How dietary fiber helps the intestine maintain gut health

Andreas Bäumler, Ph.D.

Mariana X. Byndloss

UC Davis Health researchers have discovered how by-products of the digestion of dietary fiber by gut microbes act as the right fuel to help intestinal cells maintain gut health.

The research, published August 11 in the journal Science, is important because it identifies a potential therapeutic target for rebalancing gut microbiota and adds to a growing body of knowledge on the complex interplay between gut microbiota and dietary fiber.

An accompanying Insights / Perspectives article in the same issue of the journal describes gut microbes as “partners” in the body’s defense against potential infectious agents, such as Salmonella.

“Our research suggests that one of the best approaches to maintaining gut health might be to feed the beneficial microbes in our intestines dietary fiber, their preferred source of sustenance,” said Andreas Bäumler, professor of medical microbiology and immunology at UC Davis Health and senior author of the study.

Contaminated Medical Marijuana Believed to have Killed Cancer Patient

George Thompson, M.D.

A rare fungal infection has killed a California man undergoing cancer treatment and it’s believed he got it from medical marijuana, CBS Los Angeles reports.

The treatment left the man’s immune system compromised, but his death still surprised doctors because he was relatively young and his cancer was beatable. He was using medical marijuana to fend off the treatment’s effects. After his death, testing of 20 medical marijuana samples from across the state found the vast majority were contaminated with dangerous bacteria and fungi.

“It started with a couple patients that were undergoing very intensive chemotherapy and a stem cell therapy, and those patients were very immune-compromised,” explained Dr. Joseph Tuscano of the University of California, Davis Cancer Center.

The California man was one of those patients who was already in a very serious cancer fight. Then that fight suddenly became much more complicated with a relatively rare but particularly lethal fungal infection.

“We thought it was strange to have cases of such a bad fungal disease in such a short amount of time,” said Dr. George Thompson, a fungal infection expert with UC Davis Medical Center.

How maternal immune response to allergies may affect neurodevelopment

Paul Ashwood, Ph.D.

Researchers at UC Davis have published a study that illustrates how maternal immune activation could affect neurodevelopment in offspring.

Common characteristics that underlie many neuropsychiatric disorders such as autism spectrum disorder, schizophrenia, attention-deficit/hyperactivity disorder (ADHD) and bipolar disorder suggest they may share common causes. Epidemiological and clinical studies have identified links between these disorders and a family history of immune conditions. Most notably, mothers who have experienced increased immune activity during pregnancy are more likely to have a child with one of these neuropsychiatric disorders.

Led by Paul Ashwood, professor in the UC Davis Department of Medical Microbiology and Immunology, the study demonstrated that young mice showed increased hyperactivity and repetitive behaviors when mothers were exposed to allergens. The study findings were published in a paper entitled “Behavioral impact of maternal allergic-asthma in two genetically distinct mouse strains” in the journal Brain, Behavior, and Immunity.

Genetics and environment combine to influence autism-associated genes

Janine LaSalle, Ph.D.

Researchers at UC Davis have shown that a well-known neurotoxin (PCB 95) and a chromosomal duplication (Dup15q) have a profound impact on DNA methylation, the epigenetic process that can influence gene activity. These cumulative genetic and environmental “hits” alter the epigenetic landscape during development, altering genes linked to autism spectrum disorder (ASD). The study was published in the journal Cell Reports.

“We found multi-hit, cumulative impacts that are affecting epigenetic signatures in a common group of genes involved in synapses and autism,” said Janine LaSalle, professor in the Department of Medical Microbiology and Immunology. “This study is an example of how you can have two independent effects that, when combined, affect a larger set of genes important in the developing brain.”

Gut pathogens thrive on body’s tissue-repair mechanism

Andreas Bäumler, Ph.D.

Christopher-Lopez

Why do some foodborne bacteria make us sick? A paper published Sept. 16 in the journal Science has found that pathogens in the intestinal tract cause harm because they benefit from immune system responses designed to repair the very damage to the intestinal lining caused by the bacteria in the first place.

”The finding is important because it explains how some enteric pathogens can manipulate mammalian cells to get the oxygen they need to breathe,” said Andreas Bäumler, a professor of medical microbiology and immunology at UC Davis School of Medicine and lead author of the study. “It also offers new insight into developing strategies targeting the metabolism of the intestinal lining to prevent the expansion of harmful bacteria in the gut, a situation that is exacerbated by the overuse of antibiotics.”

A healthy large intestine is mostly free of oxygen, and the beneficial microbes residing there thrive in this anaerobic environment. In contrast, enteric pathogens, such as Escherichia coli in humans or Citrobacter rodentium in mice, need oxygen to survive.

Bäumler’s team discovered how these pathogens change the gut environment to favor their own growth.

“Enteric pathogens deploy virulence factors that damage the intestinal lining and cause diarrhea,” Bäumler said. “To repair the damage, the body accelerates the division of epithelial cells that form the intestinal lining, which brings immature cells to the mucosal surface. These new cells contain more oxygen and wind up increasing oxygen levels in the large bowel, creating an environment that allows gut pathogens like E. coli to outcompete the anaerobic-loving resident microbes.”

Bäumler’s research has important implications for developing new treatment strategies that target factors that compromise the intestinal-lining function or bolster microbiota composition to offer either resistance or assistance to invading pathogens.

“The rise of antibiotic-resistant strains of bacteria has become a major public health threat worldwide, Bäumler said. “As more bacterial strains do not respond to the drugs designed to kill them, the advances made in treating infectious diseases over the last 50 years are in jeopardy.”

This year, the Centers for Disease Control and Prevention identified three drug-resistant organisms – Clostridium difficile, Carbapenem enterobacteriaceae and Neisseria gonorrhoeae – as requiring urgent attention, and in May, a report commissioned by the UK government predicted that by 2050 antimicrobial-resistant infections could claim 10 million lives a year and cost up to $100 trillion from the global economy.

Understanding how gut pathogens manipulate the body’s natural defense mechanisms to grab hold and contribute to abnormal states within and beyond the GI tract is a burgeoning area of research at UC Davis. Scientists from schools and colleges across the campus are investigating antibiotic resistance as well as the influence that gut-flora imbalances have on many conditions, including brain health and behavior, obesity, inflammatory bowel disease, irritable bowel syndrome, GI cancers, cardiovascular disease, fatty liver disease, autism, arthritis and asthma.

Antibiotics increase nutrient availability for pathogens

Andreas Bäumler, Ph.D.

Franziska Faber, Ph.D.

UC Davis study details how treatment with antibiotics increases availability of oxidized sugars to generate nutrients that benefit the growth of bacterial pathogens.

The research on antibiotics has traditionally focused on the mechanisms by which they contribute to controlling the growth of bacteria as well as on the development of new drugs. But it has also been known that, paradoxically, some bacterial pathogens can benefit from the consequences of antibiotic treatment in causing disease. However, the mechanisms behind this relation remain elusive.

Antibiotics enable pathogens to breath in the gut

Antibiotics are essential for fighting bacterial infection, but paradoxically, in some instances they can make us more prone to developing diarrhea. That is because antibiotics don’t just kill “bad” bacteria; they can also kill the “good” ones normally residing in our gut to protect us from pathogens. However, the mechanisms by which our resident gut microbes confer protection against pathogens, such as Salmonella, remain poorly understood. In a paper published April XX, 2016, researchers from UC Davis and UT Southwestern figured out why.

Andreas Bäumler, Ph.D.

Our body absorbs nutrients in the small intestine, but our digestive tract cannot break down natural fibers from vegetables. Thus fibers pass through into the large intestine, which is teaming with beneficial microbes that are specialized on breaking down this plant material into a short organic acid, termed butyrate. To generate energy for water absorption, our cells lining the large intestine then use oxygen to burn microbe-derived butyrate; that’s how we consume fiber. A team led by Dr. Baumler found that when mice were given antibiotics, the beneficial microbes were depleted along with butyrate, thus preventing the cells lining the large intestine to consume oxygen, which dramatically increased oxygen availability in the gut lumen. Unlike our beneficial microbes, which specialize on growing in the complete absence of oxygen, Salmonella was able to benefit from the resulting increase in oxygen availability, which drove a bloom of the pathogen in the gut after antibiotic treatment. Thus by preventing beneficial microbes from providing nutrition for the cells lining our large intestine, antibiotic treatment can make us more susceptible to Salmonella infection. This finding will help to devise strategies to prevent this unwanted side effect of antibiotic treatment.

Cells sensing hostile takeover by pathogens also sound alarm to alert immune system

Renee Tsolis, Ph.D.

Researchers at UC Davis have discovered an unexpected link between how the immune system sounds an alarm when its cells are taken over by pathogens during an infection and how an inflammatory response is triggered.

The finding of this novel link, published in the journal Nature on March 23, is important because it helps researchers understand how a cell senses bacterial or viral infection, and how these pathways are linked to inflammatory diseases, such as inflammatory bowel disease, diabetes and atherosclerosis.

Surprising discovery: HIV hides in gut, evading eradication

Researchers at UC Davis have made some surprising discoveries about the body's initial responses to HIV infection. Studying simian immunodeficiency virus (SIV), the team found that specialized cells in the intestine called Paneth cells are early responders to viral invasion and are the source of gut inflammation by producing a cytokine called interleukin-1 beta (IL-1β).

Though aimed at the presence of virus, IL-1β causes breakdown of the gut epithelium that provides a barrier to protect the body against pathogens. Importantly, this occurs prior to the wide spread viral infection and immune cell killing. But in an interesting twist, a beneficial bacterium, Lactobacillus plantarum, helps mitigate the virus-induced inflammatory response and protects gut epithelial barrier. The study was published in the journal PLoS Pathogens.

One of the biggest obstacles to complete viral eradication and immune recovery is the stable HIV reservoir in the gut. There is very little information about the early viral invasion and the establishment of the gut reservoir.

"We want to understand what enables the virus to invade the gut, cause inflammation and kill the immune cells," said Satya Dandekar, lead author of the study and chair of the Department of Medical Microbiology and Immunology at UC Davis.

"Our study has identified Paneth cells as initial virus sensors in the gut that may induce early gut inflammation, cause tissue damage and help spread the viral infection. Our findings provide potential targets and new biomarkers for intervening or blocking early spread of viral infection," she said.

Breast versus bottle feeding in rhesus monkeys

Infants receiving different diets after birth develop distinct immune systems

Dr. Dennis Hartigan-O'Connor recently had a study published in Science Translational Medicine on September 3, 2014, researchers from the California National Primate Research Center (CNPRC) at UC Davis and from UC San Francisco have shown that breast-and bottle-fed infant rhesus macaques develop different immune systems.

Diet has a strong influence on the intestinal microbiota in both humans and animal models. It is well established that microbial colonization is required for normal development of the immune system and that specific microbial constituents prompt the differentiation or expansion of certain immune cell subsets. Nonetheless, it has been unclear how profoundly diet might shape the primate immune system or how durable the influence might be. We show that breast-fed and bottle-fed infant rhesus macaques develop markedly different immune systems, which remain different 6 months after weaning when the animals begin receiving identical diets. In particular, breast-fed infants develop robust populations of memory T cells as well as T helper 17 (TH17) cells within the memory pool, whereas bottle-fed infants do not. These findings may partly explain the variation in human susceptibility to conditions with an immune basis, as well as the variable protection against certain infectious diseases.

UC Davis researchers discover how cells distinguish friend from foe

Dr. Andreas Baumler, Professor in the department of Medical Microbiology and Immunology at UC Davis, and his team have shown how the innate immune system distinguishes between dangerous pathogens and friendly microbes. Like burglars entering a house, hostile bacteria give themselves away by breaking into cells. However, sensing proteins instantly detect the invasion, triggering an alarm that mobilizes the innate immune response. This new understanding of immunity could ultimately help researchers find new targets to treat inflammatory disorders. The paper, titled "Manipulation of small Rho GTPases is a pathogen-induced process detected by NOD1" was published in Nature on March 31.
