Utilizing Gnotobiotic Mice to Understand the Role of the Microbiome in Murine Disease Models
The environmentally exposed surfaces of mammals, such as the skin, mouth, gut, and vagina, are colonized by a diverse ecosystem of microbes. Though many of these bacteria - particularly those of the distal gut - are considered symbiotic, the microbiome has the capacity to induce both pro- and anti- inflammatory responses. Accumulating evidence suggests that a properly balanced gut microbiome is crucial for a correctly functioning immune system, and that imbalances in the microbial community of the intestine are linked to a multitude of auto-inflammatory and auto-immune diseases. This symposium will discuss the roles of the microbiome in murine models of various inflammatory disease states, and the advantages to utilizing germ-free/gnotobiotic mice when probing disease models with a microbiome component.

Lora Hooper (UT Southwestern) 1: Mammalian gut microbiota: Mammals and their symbiotic gut microbes
https://www.ibiology.org/immunology/gut-microbiota/ Overview: Dr. Hooper studies how the gut microbiota changes during illness or disease and how it influences our ability to fight infections. In part 2, Hooper explains how a healthy gut microbes induce a host protein called RegIIIγ which helps to protect the host from infection by pathogenic gram-positive bacteria. Detailed description: In this lecture, Dr. Hooper introduces us to the fascinating world of human microbiota; the microorganisms that live within our bodies. Although we may think that most bacteria are harmful, Hooper provides ample evidence that symbiotic gut microbes are important to good human health. Her lab is interested in understanding how the microbiota changes during illness or disease and how it influences our ability to fight infections. Using germ-free mice, they were able to demonstrate that a healthy microbiota can shape development of the host immune system and provide protection against dangerous infections like salmonella. In the second part of her talk, Hooper explains how the balance of organisms in the microbiota is maintained. By comparing DNA microarray data from normal mice and germ-free mice, Hooper’s lab was able to look for genes induced by the microbiota. They identified RegIIIγ, an important protein involved in the protection against pathogenic bacteria. They showed that RegIIIγ forms pore complexes in the membranes of gram-positive bacteria and kills them. In mice and humans, the intestinal epithelium is coated with a layer of mucus. Typically, there is a gap between gut bacteria, which are found in the outer part of the mucus layer, and the epithelial cells. Hooper’s lab showed that RegIIIγ helps to maintain this gap by preventing gram-positive bacteria from colonizing the intestinal epithelial surface. This, in turn, prevents infection of the host. Speaker Biography: Although she always was interested in science, Lora Hooper’s love for biology started after taking an introductory class at Rhodes College in Memphis, TN where she was an undergraduate. Hooper continued her graduate education in the Molecular Cell Biology and Biochemistry Program at Washington University in St. Louis where she joined Dr. Jacques Baenziger's lab. For postdoctoral training, she stayed at Washington University, in the lab of Jeffrey Gordon, where she began her studies of the interaction between gut bacteria and host cells and discovered that bacteria have the capacity to modify carbohydrates important for cell signaling. Currently, Hooper is a Professor at The University of Texas Southwestern Medical Center and a Howard Hughes Medical Institute Investigator. She has established one of the handful of mouse facilities that have the capacity to breed germ-free mice. Using these mice, her lab explores the symbiotic relationship between a host and its microbiota with the aim of providing insight into human health. Hooper was a recipient of the Edith and Peter O’Donnell Awards in 2013 and in 2015 she was elected to the National Academy of Sciences.

Exercise and gut bacteria
We’re learning what a vital role good gut bacteria play in immune health, brain health, mood, and, of course, gut health. One of the best health quotes of all time is… “Health comes from above, down, inside, out” We also know that the best way to beef up your good gut bacteria is through eating lots of different kinds of vegetables and fruits every day. But researchers have discovered yet another way to promote healthy gut bacteria: Regular exercise. Our digestive tract is home to trillions of gut bacteria that weigh about three to four pounds all together, and are made up of over a 1,000 different species and 5,000 strains. This is the very definition of a symbiotic relationship. Our body depends on these gut bacteria to: • Metabolize nutrients • Protect the intestinal wall • Produce vitamin K and short chain fatty acids (SCFA), which are important for immune health • Maintain health of the digestive tract • Regulate immunity • Prevent inflammation • Promote good brain health and function - infant many studies are even finding that Parkinsons may actually start in the gut and work its way up the vagus nerve into the brain. But that is another post for another blog. Very interesting stuff though. As our understanding of healthy gut bacteria evolves, so does the information on how to cultivate your own “microbiome” while inhibiting overgrowth of “bad” bacteria that are infectious and inflammatory. This imbalance of good and bad bacteria is often what is referred as dysbiosis - Too many bad bacteria and not enough good bacteria. Initially, fermented foods and probiotics were thought to be the main recourse for improving gut health, and they do go a long ways. But, they are not the only way. Then we learned eating a diet comprised primarily of vegetables and fruits and continually changing up the produce you eat is a great way to develop a rich and diverse gut bacteria population. Now, scientists have used both a mouse study and a human study to show regular exercise, independent of diet or other factors, also promotes healthy gut bacteria. Meaning that if you do nothing other than exercise you can beneficially change your gut bacteria. In the first study, researchers transplanted fecal material from both exercised and sedentary mice into mice with sterile guts. The activity level of the mice receiving the transplants clearly mirrored that of their donors, showing that the kind of gut bacteria we have plays a role in how inclined we are to be sedentary or active. The exercised mice recipients also showed more bacteria that produce butyrate, a short-chain fatty acid (SCFA) that promotes healthy intestinal cells, reduces inflammation, and increases energy. They also were more resistant to ulcerative colitis. N-butyrate is THE most important short chain fatty acid. In the second study, researchers tracked the composition of gut bacteria in 18 lean and 14 obese adults as they transitioned from a sedentary lifestyle, to an active one, and then back to a sedentary one. Their exercise routine consisted of 30 to 60 minutes of cardiovascular exercise three times a week for six weeks. Their diets remained the same.

Food for Good Gut Bacteria w/ Drs Justin & Erica Sonnenburg
Episode #81: Drs  Justin and Erica Sonnenburg are two top microbial scientists at Stanford University and author of The Good Gut. In this interview these two pioneers share diet tips from their work at Stanford that can help you increase the diversity of the trillions of bacterial organisms in your gut, boost your metabolism and reduce inflammation. The Good Gut Book: http://amzn.to/1SYkEeB Read the Interview Show Notes: http://highintensityhealth.com/justin-erica-sonnenburg-top-foods-to-fuel-healthy-gut-bacteria/ --------------------------------------Lets Connect---------------------------------- ➢ Facebook https://www.facebook.com/MikeMutzelMS ➢ Listen to the Audio in iTunes: http://highintensityhealth.com/itunes ➢ Instagram https://www.instagram.com/metabolic_mike --------------------------------------Key Takeaways--------------------------------- 2:29 The Power of Microbes: Over the past decade there has been an awakening about the gut, microbiome and genetics. Microbes connect in major ways to human biology with digestion, metabolism, systemic immune function and central nervous system. There is no part of our body that is not touched, directly or indirectly, by these microbes in some way. 4:32 Microbial Digestion: Gut microbes rely upon complex carbohydrates (dietary fiber) to complete their functions in the gut. They digest our resistant complex polysaccharides that come from plant material; fruits, vegetables, legumes, and whole grains. At the same time, they release compounds into our gut that are soaked into our bloodstream that do things like help maintain our immune system balance and help us decide whether we are storing calories or burning them. 5:56 Feed Your Microbes: High fiber foods feed your microbes. The Sonnenburgs make sure that their family consumes high fiber foods at every meal. 7:30 Microbial Diversity – The Jelly Bean Analogy: Think of each species of gut bacteria as a color of jelly bean. The Western diet will be a simple mix of a few colors. Modern day hunter gatherers or those who live similarly to those at the beginning of agriculture, have many more colors of jelly beans. They have species of gut bacteria that are not seen in the Western world. In the environment, if an ecosystem loses its diversity, it’s a bad thing. Potentially, that is the case with our microbial ecosystem? 9:25 A Skewed Perspective of Microbes: Research has primarily focused on Westerners, but now research is looking into populations around the globe. The NIH Human Microbiome Project spent years working to determine what a healthy microbiota is and working to determine how the microbiome changes in different disease states. 10:20 Microbiota, a Key Player in Disease: Just because someone is healthy, doesn’t mean they have a healthy microbiota. Evidence is building that shows that most Americans have unhealthy gut microbiota, which predisposes us to many Western diseases. Metabolic syndrome, heart disaease, autoimmune diseases, cancers, and the like, are all become more prevalent. It is possible that there are individual causes for these diseases, but more likely, that there are only a few causes and that gut microbiota is central of them. 11:54 Traditional Societies: Humans have spent 95% of our time on the earth as hunter gatherers. By looking at hunter gatherer societies today, we can get a better understanding of what our gut microbiota is supposed to be. 13:39 The High MAC Diet: Microbiota Accessible Carbohydrates are dietary fiber that we consume to feed our microbiota. Tubers eaten by hunter gatherers have not been modified by agriculture, making it texturally and nutritionally different from what we eat. Since we cannot recreate the diet of hunter gatherers, we can eat lots of different foods, including tubers, along with berries and leafy greens and increase fiber to diversify and sustain our microbiota. 15:56 Polyphenols: When researching the impact of plant fiber, it is challenging for researchers to parse out the other benefits of the consumption of plants. In general, Westerners should eat more plants that contain complex dietary fibers, not only to feed their microbiota, but to garner the other benefits. 18:01 Fiber Consumption Comparison: Hunter gatherers consume about 150 – 200 grams per day of dietary fiber. In the U.S., we struggle to eat 15 grams per day. If you starve the microbes in the gut, they begin to consume the mucus lining of your digestive tract. 19:32 Short Chain Fatty Acids Created By Our Microbiota: Acetate, propionate, and butyrate are the major ones. In mice, propionate has been shown to be a regulator of metabolism. Butyrate and propionate have shown in mice to be a regulator of inflammation. They may also play a role in satiety. One day we will have enough information to match our foods to specific microbes in our gut. Increase dietary fiber, to increase short chain fatty acids.

The microbiota as instructor and arbiter of immune responses in health and disease
The microbiota as instructor and arbiter of immune responses in health and disease Air date: Wednesday, February 22, 2017, 3:00:00 PM Category: WALS - Wednesday Afternoon Lectures Runtime: 01:07:59 Description: NIH Director's Wednesday Afternoon Lecture Series The vertebrate intestinal tract is colonized by hundreds of species of bacteria that outnumber the total cells in the host, yet must be compartmentalized and tolerated to prevent invasive growth and harmful inflammatory responses. A key function of commensal microbes is to contribute to the adaptive immune repertoire and to diverse lymphocyte effector functions. T cell responses against non-invasive commensals contribute to shaping the repertoire of effector/memory and regulatory T cells. How T cells elicited by commensal bacteria can influence autoimmunity is a central question that remains unsolved. The Littman Lab studies the antigenic specificity of microbiota-induced T cells and the mechanisms by which their functions are acquired upon interaction with distinct commensal species. His lab finds that Th17 cells, which are central to mucosal barrier defense but also participate in autoimmune disease, are induced by specific constituents of the microbiota, and acquire effector function only after additional exposure to endogenous adjuvants, such as the serum amyloid A proteins. The lab's studies in mice are not only relevant for human autoimmune diseases, many of which have Th17 cell involvement, but may also provide insights into how commensal microbe-specific T cell responses could be harnessed for mucosal vaccination and cancer immunotherapy.

Gut Bacteria and Mental Health: How Inflammation Affects Us:  Thomas DeLauer
Please Subscribe for 3-4x Videos Per Week! http://www.ThomasDeLauer.com Gut Bacteria and Mental Health: How Inflammation Affects Us: Thomas DeLauer Microbiomes are communities of microorganisms that are a combination of both beneficial and potentially harmful bacteria Lifestyle factors such as exercise and managing stress appear to dramatically affect the diversity and quantity of healthy microbiome in the intestines The human gut harbors over 100 trillion microorganisms - approximately 10 times the number of cells in the human body Microbes begin residing within human intestines shortly after birth. These microbiomes are vital to the development of the immune system and various neural functions – known as the gut-brain axis *The gut-brain axis is the biochemical signaling that takes place between the gastrointestinal tract and the central nervous system* An increasing body of research results confirms the importance of the "gut-brain axis" for neurology and indicates that the triggers for a number of neurological diseases, specifically anxiety and depression, may be located in the digestive tract How the Gut Interacts with the Brain The gut is connected to the brain via the vagus nerve, the enteric nervous system, and the gut-brain axis. Vagus Nerve The vagus nerve extends from the brainstem down into the neck, thorax, and abdomen. The nerve exits the brainstem through rootlets in the medulla that are caudal to the rootlets for the ninth cranial nerve The vagus nerve supplies motor parasympathetic fibers to all organs except adrenal glands, all the way from the neck down to the second segment of the transverse colon. It helps regulate heart rate, speech, sweating, and various gastrointestinal functions. Enteric Nervous System The enteric nervous system connects with the central nervous system. It contains 200-600 million neurons Local and centrally projecting sensory neurons in the gut wall monitor mechanical conditions in the gut wall. Local circuit neurons, on the other hand, integrate this information. This enables motor neurons to influence the activity of the smooth muscles in the gut wall and glandular secretions such as digestive enzymes, mucus, stomach acid, and bile The enteric nervous system has been referred to as a “second brain” because of its ability to operate autonomously and communicate with the central nervous system through the parasympathetic (i.e., via the vagus nerve) and sympathetic nervous systems. Gut-Brain Axis Finally, the gut-brain axis consists of bidirectional communication between the central and the enteric nervous system, linking emotional and cognitive centers of the brain with peripheral intestinal functions. There is strong evidence from animal studies that gut microorganisms can activate the vagus nerve and play a critical role in mediating effects on the brain and behavior. (1) Connections between the gut and the brain/Anxiety and Depression Recent studies on laboratory animals that grow up without any microorganisms (germ-free) show that microorganisms in the gut are capable of influencing mood Maintaining a Healthy Gut No one knows the exact ingredients for a healthy microbial gut; however, having a diet rich in probiotic foods to maintain a healthy gut seems like the way to go Probiotics seemingly boost mood in two important ways: They generate a particular neurotransmitter called gamma-aminobutyric acid (GABA) and also enhance the brain receptors for GABA as well. GABA is calming amino acid, known to calm areas of the brain that are over active in anxiety and panic and in some forms of anxious depression.

How The Gut Microbiota Affects Our Health with Dr. Erica & Dr. Justin Sonnenburg
Dr. Justin Sonnenburg is an associate professor of microbiology and immunology at Stanford and Dr. Erica Sonnenburg is a senior research scientist in the Sonnenburg lab where they the research many aspects the interaction between diet with the 100 trillion or so bacteria in the gut (specifically the colon) and how this impacts the health of the host (which in this case is a laboratory research mouse). In this episode we discuss the pivotal role fiber plays in fueling good bacteria in the gut to produce compounds that regulate the immune system including increasing the number of T regulatory cells, which are specialized types of immune cells that keep the immune system in check and prevent autoimmune responses, and how these compounds also increase other types of blood cells in the body in a process known as hematopoiesis. We also talk about how the lack of fiber in the typical American diet actually starves these good bacteria of their food. This has an effect not only on the immune system and autoimmune diseases but also results in the breakdown of the gut barrier, which leads to widespread inflammation and inflammatory diseases. Lastly, in this podcast, Dr. Erica Sonnenburg talks about how C-sections, have a negative effect on the infant’s gut due to the lack of exposure to bacteria present in the mother’s vaginal canal, and how the use of formula deprives the infant not only from the good bacteria present in Mom’s gut but also from special carbohydrates in breast milk that are good for the infant gut flora known as HMOs or human milk oligosaccharides. ▶︎ Get the show notes! https://www.foundmyfitness.com/episodes/the-sonnenburgs Links related to the Sonnenburgs: ▶︎ http://sonnenburglab.stanford.edu/ ▶︎ http://www.facebook.com/thegoodgut ▶︎http://www.amazon.com/gp/product/1594206287/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=1594206287&linkCode=as2&tag=foun06-20&linkId=IOKAGDTRCL47XQN6 Links related to FoundMyFitness: ▶︎ Join my weekly newsletter: http://www.foundmyfitness.com/?sendme=nutrigenomics ▶︎ Crowdfund more videos: http://www.patreon.com/foundmyfitness ▶︎ Subscribe on YouTube: http://www.youtube.com/subscription_center?add_user=foundmyfitness ▶︎ Subscribe to the podcast: http://itunes.apple.com/us/podcast/foundmyfitness/id818198322 ▶︎ Twitter: http://twitter.com/foundmyfitness ▶︎ Facebook: http://www.facebook.com/foundmyfitness ▶︎ Instagram: http://www.instagram.com/foundmyfitness

We have 3 key questions regarding weight loss. Have you struggled with your weight? Have you tried numerous diets where you've lost weight, but then ended up regaining those pounds and more? Have you given up? If you answered “Yes” to any of these questions, then the answer resides in the makeup of your gut microbiome. While an unhealthy diet, a sedentary lifestyle, and perhaps your genetic makeup can contribute to your battle of the bulge, more and more research is showing that this is not a human genetic issue but rather a microbiome issue. Many times, the foods you crave, have very little to do with want you want. Rather it's your microbiome that's influencing your food choices. How to we know this to be true? Well, the most famous study in this area is the one done on identical human twins. Each twin has the same genetic makeup. However one twin was overweight and the other twin was lean. The researchers then took their human microbiome and injected it into the gut flora of mice so that the microbiome of the mice took on the nature of the human twin. Each recipient mice was given the same diet and daily activities. The results were that the mice with the microbiome from the lean human twin stayed lean. And, the mice with the mircobiome from the overweight human twin gained weight and stored fat. For the overweight twins, their microbial community was dominated by Firmicutes. Whereas, the microbial community of the lean twins were dominated by Bacteroidetes. Unfortunately, there are several common triggers that increase firmicutes over bacterioidetes: Trigger 1 – High intake of omega-6 fatty acids from vegetable oils. Most processed foods use some form of vegetable oil for shelf stability. The problem is these types of omega-6 oils trigger inflammation, which favors the Firmicutes. Trigger 2 – Animal protein creates less diversity in the microbial community, which then allows the Firmicutes to dominate. Trigger 3 – Sugar and processed carbohydrates, like modern-day wheat, are fuel for Firmicutes, which again allows them to dominate your abdominal microbiome. Trigger 4 – Stress triggers the releases of adrenal hormones like cortisol and adrenaline, which lower the Bacterioidetes in your abdominal cavity. To help you started on the right path, Judy and I would like to offer you a 4 step program. Step #1 – Eliminate omega-6 vegetable oils from your diet. Ones like Soybean Oil Canola Oil Vegetable Oil While the food industry, and our government, have tried to convince us that these omega-6 vegetable oils are safe and heart-healthy, they are not. These oils are inflammatory, and help create an environment that allow Firmicutes to flourish, which then creates toxins that your body has to address. Step #2 – Replace the omega-6 vegetable oils with omega 3 healthy fats like Coconut Oil Avocados Grass-fed Butter Fish Rich in Omega 3s Grass-fed Beef Extra-virgin Olive Oil When used in weight management studies, these healthy, anti-inflammatory omega 3 fats create an environment where healthy gut flora can dominate, which lowers inflammation levels, produces significantly less toxins, and increases the probability of weight loss. Step #3 – Eliminate Wheat from your diet. Why are we targeting wheat. Because modern-day wheat has been genetically engineered so that it now has a higher glycemic index that table sugar. It's fuel for firmicutes and a toxin producer. Step #4 – Limit Your Sugar Intake Most of the foods you eat come packaged. With a section on the label for Nutrition Facts. Find it and locate the line that says “Total Carbohydrate” Under this you will see a line that says “Total Sugars” This is the line that you want to pay attention to. Here's what you need to remember: 1 teaspoon of sugar is equal to 4 grams. If you divided the number of grams of sugar by 4 you will determine the number of teaspoons of sugar per serving. Ideally you only want to consume foods that are less than 1 teaspoon or 4 grams of sugar per serving.

Gut Microflora Destroyed During Long Hosptial  Stays w/ John Alverdy, MD
Listen to the Podcast in iTunes: http://highintensityhealth.com/itunes Show Notes-- 4:06 Healing from Surgery and Gut Flora: When you are a surgical patient, you have your procedure, you go home, and you start eating your regular food. You have generally had one shot of antibiotics, which assaults your gut microbiome, but you can rebuild your gut flora quickly at home by resuming your regular diet. There are about 80,000 elective operations done every day and most of us heal quickly at home. 5:00 Longer Hospital Recovery and Gut Biodiversity: Sometimes we have a prolonged recovery, for example after, a car accident, a liver transplant, or burn injuries. In the intensive care unit, even when there is no identified source of infection, doctors will put 80% of us on antibiotics unnecessarily. 6:37 The Consequences of Unnecessary Antibiotics in Prolonged Recovery: It is called ecological collapse of the normal gut biome. Your normal health-promoting microbiome is replaced with a pathobiome. Harmful, pathogenic, bacteria become predominant in your gut. This dysbiosis can directly impair the immune system and directly and adversely affect the outcome. Instead of being better in a day or two, it may take you 2 weeks to recover. 7:23 The Impact of a Pathogenic Gut Microbiome on the Immune System: There is now evidence that your normal gut bacteria drive your entire body’s immune response. Studies in animals show that even a sterile incision distant from the gut heals much worse if you destroy the gut microbiome. 8:25 Overuse of Antibiotics: Dr. Alverdy is glad that we have antibiotics. They save countless lives. Clearly, we are overusing them. Now that we have the molecular tools to understand it and as we have the science to back it up, we can use this science to change the clinical course of treatment. Perhaps, we could narrow the antibiotic’s spectrum or use alternative approaches like delivering the antibiotic to the wound site rather than systemically. 10:36 Chemically Defined Diets Impact Upon Gut Biodiversity: With food, the whole is greater and more powerful than the sum of its parts. Using chemicals that have many of the components of food does not feed the microbiome and does not fully nourish the body. Using chemicals that have the components of the gut flora byproducts does not nourish the body either. Chemically defined diets are inadequate. They do not have the same effect on the microbiome, and thus the immune system, as real food. We cannot eat real food when we are very sick. Dr. Alverdy is hoping that through the sciences of metabolomics, proteomics, and microbial genetics, we will make discoveries that will allow us to better nourish our people and their gut microbiome. 14:15 Prophylactic Probiotics before Surgery: Probiotic supplements offer a few strains of bacteria for the gut. To re-faunate the gut, you would need a multitude of bacterial strains to create the diversity required to maintain your health. 17:25 The Leaky Gut and Endotoxin Relationship: In leaky gut, your gut lining has been compromised and toxins, released by your gut bacteria, leaks into your bloodstream in small amounts, triggering an immune response. Leaky gut is being linked in theory to diseases for which there is no identified infectious agent, like autism, MS, and fibromyalgia. It is unclear whether the endotoxin in the blood is a marker for the problem or it is driving the problem. In Dr. Alverdy’s opinion, it is more likely that the endotoxin is the result of the leaky gut rather than the cause. 18:58 Your Gut is REALLY Smart: Your GI tract is discriminating. It lets the good stuff in and keeps the bad stuff out. It constantly surveys what is in the gut, so it can be ready for anything at any time. It is a very molecularly complex process. Lymph nodes serve as checkpoints where intruders are identified and detoxified. The endotoxin that may seep through a permeable intestine would probably be mostly detoxified. 20:25 Microbial Shifts Post Surgery: In a recent study, gastric bypasses were performed on mice. Their stool microbiome dramatically changed. Pre-surgery stools and post-surgery stools were transplanted into over-weight mice. The overweight mice that received the post-surgery stool lost weight. They also had improved glucose tolerance, improved metabolic syndrome, and improved fatty liver. Gastric bypass, through alterations in the gut microbiome, appears to change energy efficiency and energy regulation. We are nowhere near a place where we can take a pill to implement these changes and lose weight. It could be that people who struggle with their weight all of their lives, have some sort of altered energy balance. They are eating more than

Breaking News  - Study links gut bacteria to every age-related disease
Changing your diet to maintain healthy gut bacteria could help to protect you from nearly all age-related diseases, new research suggests.Imbalanced gut bacteria may to blame for many age-related diseases, according to the new study from University Medical Center Groningen, The Netherlands.The researchers found that the poorly balanced gut bacteria in older mice could induce ‘inflammaging’ in younger mice when it was transplanted to them.Inflammaging is a chronic inflammation condition associated with aging, which is linked to most serious age-related health conditions, like stroke, dementia and cardiovascular disease.Scientists know that elderly people tend to have different gut bacteria profiles from younger people. This new research suggests that this change in balance is linked to inflammaging, which is in turn related to most late-onset diseases and disorders.In recent years, we’ve found out that the gut is at the heart of just about everything, with many calling our second brain.Inflammaging is a catch-all term for the tendency of elderly people to have generalized inflammation. It is thought to be related to evolved changes that the immune system undergoes as a person gets older.It isn’t clear whether aging causes inflammation or inflammation causes aging, but the two go hand-in-hand, and susceptibility to many diseases goes along with both of them.Since they knew that the bacterial microbiome also undergoes changes with age, the researchers, led by Dr Floris Fransen, wanted to test the relationship between the three factors.They took samples from older mice – whose gut bacteria composition, like humans’, changes with age – and introduced them to the bodies of younger mice. After the procedure, the younger mice developed chronic inflammation, like the inflammaging that would normally have struck them later in life.The scientists also transplanted gut bacteria from one group of younger mice to another group of mice of around the same ages to see if the immune response was just to the introduction of foreign bacteria.But only the mice with transplanted gut bacteria from older ones developed inflammaging.The differences in the responses suggested to the researchers that aging leads to an imbalance in gut bacteria, such that there are more ‘bad’ bacteria than good in the microbiome.The proliferation of the bad bacteria leaves the gut lining more permeable to toxins that can contaminate the bloodstream and lead to disorders like inflammatory bowel disease, obesity, diabetes, anxiety, autism and even cancer.The study suggests a causal relationship between aged gut bacteria and inflammaging in mice, and, though the same has not been proven in humans, the researchers report that a correlation has already been observed.Still, the findings are enough to determine that ‘strategies that alter the gut microbiota composition in the elderly,’ such as developing a good diet and taking probiotics and prebiotics, ‘reduce inflammaging and promote healthy aging,’ says Dr Fransen.

WILL BABY POOP BACTERIA BECOMES THE NEW PROBIOTIC? Could the key to better gut health reside in a probiotic cocktail brewed from the contents of an infant's dirty diaper? That's the question driving a new line of research investigating the power of baby poop as a potential source of microbes that could contribute to healthier digestion. And experiments recently showed that certain types of bacteria extracted from baby feces could promote the production of short-chain fatty acids (SCFA) in mice, and in a medium simulating the human gut. SCFA molecules are a subset of fatty acids that are churned out by some types of gut microbes during the fermentation of fiber. They're associated with maintaining gut health and protecting against disease, so a probiotic containing baby-poop microbes could provide health benefits by boosting SCFA production in a compromised digestive system, researchers reported in the new study. [5 Ways Gut Bacteria Affect Your Health] "Short-chain fatty acids are a key component of good gut health," lead study author Hariom Yadav, an assistant professor of molecular medicine at Wake Forest School of Medicine, said in a statement. "People with diabetes, obesity, autoimmune disorders and cancers frequently have fewer short-chain fatty acids. Increasing them may be helpful in maintaining or even restoring a normal gut environment, and hopefully, improving health," Yadav said. Fecal microbiota transplants (FMT), or "poop transplants," can treat a type of gut disorder with an infusion of diverse bacteria from a healthy digestive system, distilled from a donor's poop. This helps to correct imbalances of microbial diversity when the gut microbiome is dominated by the bacteria Clostridium difficile (C. diff), which can lead to serious gut disorders. Previous studies have investigated the use of probiotics — those healthy gut bacteria — by testing their impact in guts already affected by disease, the researchers wrote in the study. For the new investigation, they wanted to see how a probiotic would impact SCFA production in a healthy gut. They chose to work with baby poop because infants' gut microbiomes are typically free from age-related diseases "such as diabetes and cancer," and because of the sheer abundance of infant feces at their disposal. ("Their poop is readily available," Yadav said.) In the small, new study, the researchers isolated 10 bacterial strains — five species of Lactobacillus bacteria, and five species of Enterococcus — in samples from 34 babies, identifying the strains as good candidates for crafting a probiotic cocktail of microbes that could survive in a human host's gut and stimulate SCFA production, according to the study. They then tested different doses of the 10-bacterial probiotic blend in mice, as well as in a slurry of human feces meant to mimic the environment of a human digestive system. The scientists found that even single doses maintained the healthy microbial balance and increased SCFA production in both the mice and the feces medium, the researchers reported. "This work provides evidence that these human-origin probiotics could be exploited as [treatments] for human diseases associated with gut microbiome imbalance and decreased SCFA production in the gut," Yadav said. Still, much more research is needed before you'll find baby-poop probiotics on the shelves of your health-food stores. "Our data should be useful for future studies aimed at investigating the influence of probiotics on human microbiome, metabolism and associated diseases," Yadav said. The findings were published online Aug. 23 in the journal Scientific Reports.

Hidde Ploegh (Boston Children’s Hospital) 1: Immunology: The Basics of Antibody Diversity
https://www.ibiology.org/immunology/antibody-diversity/ Dr. Ploegh describes how antibody diversity lets us resist the multitude of infectious agents we encounter every day. He also explains how camelid antibody fragments are changing medicine. Talk Overview: How does our immune system protect us against all of the infectious agents and foreign substances we encounter? Much of the answer lies in antibody diversity.  In his first talk, Dr. Hidde Ploegh explains how B cells shuffle their genetic material such that regions of the immunoglobulin protein are rearranged. This generates the antibody diversity needed to recognize an almost infinite number of antigens. Interactions of B cells with T helper cells results in the formation of structurally distinct classes of immunoglobulins, further increasing antibody diversity.  T killer cells are primed to attack infectious agents when immunoglobulins on their surface recognize antigens presented by the major histocompatibility complex (MHC). Ploegh explains that by subverting the MHC pathway, viruses and cancer cells can evade the immune system. In part two, Ploegh describes how his lab takes advantage of the unique properties of antibodies from the Camelidae family (alpacas, llamas, camels, etc). In addition to traditional antibodies, these animals naturally make small, heavy-chain only antibodies (nanobodies). These molecules can be isolated, amplified in bacteria, and engineered for new applications. As well as using nanobodies to target viruses and inflammasomes, Ploegh explains how his lab uses labelled nanobodies for non-invasive, live imaging of cancer tumors in mice. These technologies have exciting implications in basic and biomedical studies. Speaker Biography: Dr. Hidde Ploegh is an immunologist at Boston Children’s Hospital. His love for immunology began when he was an undergraduate at the University of Groningen in the Netherlands. As a student, he wrote a letter to renowned immunologist Jon van Rood but never heard back. However, as an undergraduate researcher, he had an opportunity to work with Dr. Jack Strominger at Harvard University for 6 months. The experience was so great that after earning a BS and Masters in Biology and Chemistry from the University of Groningen, he returned to Strominger’s lab for his graduate studies. Ironically, his thesis committee chair ended up being Jon van Rood. Ploegh ultimately received his PhD from Leiden University in the Netherlands. Following graduate school, Ploegh was highly sought after by several institutions. Fresh from his PhD, Ploegh was first offered a position as a junior group leader in immunology at the University of Cologne, Germany in 1980. Since then, he has worked at the Netherlands Cancer Institute, Massachusetts Institute of Technology, Harvard Medical School and most recently, the Whitehead Institute. His accolades, in addition to prestigious awards, include induction into the European Molecular Biology Organization (1986), the American Academy of Arts and Science (2002) and the National Academy of Sciences (2012). He has contributed to over 500 papers.

Diet and Gut Microbiota - mSystems
Dietary modification has long been used empirically to modify symptoms in inflammatory bowel disease, irritable bowel syndrome, and a diverse group of diseases with gastrointestinal symptoms. There is both anecdotal and scientific evidence to suggest that individuals respond quite differently to similar dietary changes, and the highly individualized nature of the gut microbiota makes it a prime candidate for these differences. To overcome the typical confounding factors of human dietary interventions, here we employ ex-germfree mice colonized by microbiotas of three different humans to test how different microbiotas respond to a defined change in carbohydrate content of diet by measuring changes in microbiota composition and function using marker gene-based next-generation sequencing and metabolomics. Our findings suggest that the same diet has very different effects on each microbiota’s membership and function, which may in turn explain interindividual differences in response to a dietary ingredient.

Effects of Stress - How does stress affect to our health - Torii Labs - Plant Medicine Company
Visit our website: https://toriilabs.com Subscribe to our Channel: http://www.enlaze.es/toriiyt Torii Labs - Plant Medicine Company - Herbal Elixirs How does stress affect our health Stress hormones called CRF’s can cause inflammation in the gut and affect the diversity and health of the microbiome in our intestinal tract. Research in mice has found that exposure to stress led to an overgrowth of certain types of bacteria while simultaneously reducing microbial diversity in the large intestine of the stressed mice. Due to our strong gut-brain axis, a stressed gut can cause depression and other psychological disorders by reducing essential neurotransmitters such as dopamine and serotonin, of which 95% are produced in our large intestinal tract. As the HPA system becomes depleted from excessive and prolonged activation we are unable to produce healthy amounts of stress hormones which is essential to feeling energized and focused. This is typically known as adrenal fatigue. In conclusion – stress is something we have to address on a daily basis. When managed properly it facilities a positive physiological response that helps us response effectively to the demands and threats that we encounter. However, if the fight or flight response is prolonged, usually through emotionally driven perceived threats, then the body and mind can experience a multitude of diseases that deplete our well-being and vitality.

The Microbiome and Mental Health
Each month The Brain & Behavior Research Foundation hosts a Meet the Scientist Webinar featuring a researcher discussing the latest findings related to mental illness. In July, 2017, the Foundation featured Dr. Christopher Lowry of the University of Colorado, Boulder. Description: Stress can aggravate inflammatory diseases by affecting the relationship between gut bacteria and the immune system. Treatment with immune-regulating bacteria may help prevent against stress-induced illness, a study in mice suggests. In this study, Dr. Lowry investigates how stress acts on the normal relationship between the body and the microbial community occupying the body, which is collectively called the microbiota. Dr. Lowry found that stress disrupts this relationship, resulting in elevated inflammation. These findings can help researchers develop microbiome- and immunoregulation-based strategies to prevent disorders related to stress.

Fecal transplants & why you should give a crap | Mark Davis | TEDxSalem
How swallowing someone else's poop could save your life! Dr. Mark Davis is a Portland-based naturopath who specializes in stomach and intestinal health. He is an expert in fecal transplantation, having successfully administered it for patients of many conditions. Davis cofounded Microbiomes, LLC, which was the first group in the U.S. to offer a fecal transplant capsule, which is taken orally. He hopes that the U.S. Food and Drug Administration will eventually allow more patients to benefit from fecal transplantation.

Photo by Artak Petrosyan on Unsplash Reference Details For MTT: Article Abstract Microbiota Transfer Therapy alters gut ecosystem and improves gastrointestinal and autism symptoms: an open-label study. Publication Microbiome - Jan. 23, 2017 Author(s) Dae-Wook Kang, James B. Adams, Ann C. Gregory, Thomas Borody, Lauren Chittick5,15, Alessio Fasano, Alexander Khoruts, Elizabeth Geis, Juan Maldonado, Sharon McDonough-Means, Elena L. Pollard, Simon Roux, Michael J. Sadowsky, Karen Schwarzberg Lipson, Matthew B. Sullivan, J. Gregory Caporaso and Rosa Krajmalnik-Brown Background Autism spectrum disorders (ASD) are complex neurobiological disorders that impair social interactions and communication and lead to restricted, repetitive, and stereotyped patterns of behavior, interests, and activities. The causes of these disorders remain poorly understood, but gut microbiota, the 1013 bacteria in the human intestines, have been implicated because children with ASD often suffer gastrointestinal (GI) problems that correlate with ASD severity. Several previous studies have reported abnormal gut bacteria in children with ASD. The gut microbiome-ASD connection has been tested in a mouse model of ASD, where the microbiome was mechanistically linked to abnormal metabolites and behavior. Similarly, a study of children with ASD found that oral non-absorbable antibiotic treatment improved GI and ASD symptoms, albeit temporarily. Here, a small open-label clinical trial evaluated the impact of Microbiota Transfer Therapy (MTT) on gut microbiota composition and GI and ASD symptoms of 18 ASD-diagnosed children. Results MTT involved a 2-week antibiotic treatment, a bowel cleanse, and then an extended fecal microbiota transplant (FMT) using a high initial dose followed by daily and lower maintenance doses for 7–8 weeks. The Gastrointestinal Symptom Rating Scale revealed an approximately 80% reduction of GI symptoms at the end of treatment, including significant improvements in symptoms of constipation, diarrhea, indigestion, and abdominal pain. Conclusions This exploratory, extended-duration treatment protocol thus appears to be a promising approach to alter the gut microbiome and virome and improve GI and behavioral symptoms of ASD. Improvements in GI symptoms, ASD symptoms, and the microbiome all persisted for at least 8 weeks after treatment ended, suggesting a long-term impact. Similarly, clinical assessments showed that behavioral ASD symptoms improved significantly and remained improved 8 weeks after treatment ended. Bacterial and phagedeep sequencing analyses revealed successful partial engraftment of donor microbiota and beneficial changes in the gut environment. Specifically, overall bacterial diversity and the abundance of Bifidobacterium, Prevotella, and Desulfovibrio among other taxa increased following MTT, and these changes persisted after treatment stopped (followed for 8 weeks). ----------- References Full text of this article: https://microbiomejournal.biomedcentral.com/articles/10.1186/s40168-016-0225-7 Download PDF of this article here.

Save the Microbes
NYU Langone Medical Center, Lab of Martin Blaser. Humans have co-evolved with the resident microbes that call us "home", known as the microbiota, consisting of trillions of cells that colonize our bodies. The microbiota carry out many beneficial functions, such as producing vitamins, aiding in digestion, and protecting against invading microbes, but disruption from antibiotics or delivery by Caesarian section may have consequences for human health. Recently, antibiotic use has been linked with obesity and asthma. Using both human studies and experimentally observed mice, we are beginning to understand how antibiotics may lead to the disappearance of microbes and to identify key microbes that impact our health.
