Departmental News and Events
Dr. Satya Dandekar, Professor and Chair of Medical Microbiology and Immunology, is one among the three UC Davis Health faulty members who have been elected to the newest class of fellows of the American Association for the Advancement of Science (AAAS) for their scientifically or socially distinguished efforts to advance science or its applications. They are among 15 UC Davis faculty to receive the honor.
Dr. Paul Ashwood's lab has a new publication in the journal Brain, Behavior, and Immunity. The first author of the paper was Destanie Rose, a graduate student in the laboratory of Paul Ashwood.
Their research has found that children with autism spectrum disorder (ASD) have reduced immune system regulation, as well as shifts in their gut microbiota. The immune deregulation appears to facilitate increased inflammation and may be linked to the gastrointestinal issues so often experienced by children with ASD.
Dr. Barbara Shacklett's lab has a new publication in the Journal of Immunology that was selected by the journal for a special feature. The first author of the paper was Brenna Kiniry, PhD, a recent graduate of the Microbiology Graduate Group from Dr. Shacklett’s lab.
The articles highlighted in the Journal of Immunology are considered to be among the top 10% of articles published in the journal.
Dr. Renée Tsolis, Professor of Microbiology and Immunology, is one of 96 new fellows elected to the American Academy of Microbiology in 2018. Fellows of the American Academy of Microbiology, an honorific leadership group within the American Society for Microbiology, are elected annually through a highly selective, peer-review process, based on their records of scientific achievement and original contributions that have advanced microbiology. The new fellows will be honored at the ASM Microbe 2018 conference in June.
Lillian Zhang, an MD/PhD candidate in the lab of Dr. Andreas Bäumler has been awarded a Ruth L. Kirschstein National Research Service Award (NRSA) F30 Predoctoral Fellowship. Lillian is the first student in the history of UC Davis to have been awarded this prestigious fellowship.
The purpose of the Kirschstein-NRSA, dual-doctoral degree, predoctoral fellowship (F30) is to enhance the integrated research and clinical training of promising predoctoral students, who are matriculated in a combined MD/PhD or other dual-doctoral degree training program, and who intend careers as physician/clinician-scientists.
UC Davis MIND Institute researchers have shown in a mouse model that an elevated maternal immune response changes the epigenetic landscape in offspring’s microglia, immune cells found in the brain and spinal cord. These changes affect genes associated with immune signaling and neural development, some of which have been implicated in autism spectrum disorder (ASD). The study was published online in the journal Glia.
“The genes we identified that had differences in methylation and changes in expression showed an overlap or enrichment for genes that had been identified as genetic risk factors for autism, as well as genes that were differentially expressed in autism human brain samples,” said Annie Vogel Ciernia, Autism Research Training Program (ARTP) fellow, senior postdoctoral researcher in the LaSalle lab at UC Davis and first author on the paper.
The Zymo Research Corp. Board of Directors has announced the appointment of Dr. Jonathan Eisen, Biologist, to its Scientific Advisory Board, effective immediately.
Dr. Jonathan Andrew Eisen currently works at the University of California, Davis. He holds appointments in the Department of Evolution and Ecology in the College of Biological Sciences and in the Department of Medical Microbiology and Immunology in the School of Medicine. Dr. Eisen's lab is located at the UC Davis Genome Center. His areas of expertise include evolutionary biology, genomics, microbiology and computational biology. He has been actively involved in the "open science" movement especially in the move towards more "open access" publishing. In addition, he is an active and award-winning science communicator.
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.
Outstanding Senior in the Global Disease Biology major
Don Nguyen, an undergraduate researcher from Dr. Satya Dandekar's lab, has been named "Outstanding Senior in the Global Disease Biology major". This award recognizes students' contributions to the intellectual environment of their department, through involvement in research or classroom discussion, leadership in student groups committed to the advancement of learning, or other intellectual pursuits with faculty and fellow students.
The Global Disease Biology academic major at UC Davis uses an integrated, One Health-based approach to advance student understanding of the concept(s) of disease, the societal and personal impacts of past, present and future diseases, and the science behind disease discoveries, causes, evolution, diagnosis, treatment, and prevention. This major is offered by College of Agricultural and Environmental Sciences and is partnered with School of Medicine and School of Veterinary Medicine.
(CBS NEWS) 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.
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.
Departmental faculty member, Shirley Luckhart, Ph.D., has been awarded the “Award for Career Excellence in Medical, Urban, and Veterinary Entomology”.
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.”
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.
UC Davis study details how treatment with antibiotics increases availability of oxidized sugars to generate nutrients that benefit the growth of bacterial pathogens.
(SACRAMENTO, Calif.) -- 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 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.
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.
For outstanding teaching and mentoring, molecular biologist Shirley Luckhart has been named the recipient of the 2016 “Award for Excellence in Service to Graduate Students,” sponsored by the UC Davis Graduate Student Association.
“This is a wonderful surprise,” said Luckhart, professor with the Department of Medical Microbiology and Immunology and adjunct professor in the Department of Entomology and Nematology.
She will receive the award on April 8 at the annual Interdisciplinary Graduate and Professional Student Award Banquet.
Luckhart, whose expertise includes molecular cell biology and biochemistry of malaria parasite transmission, was singled out for creating a thriving lab environment and her drive to help her students succeed.
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.
Highly active anti-retroviral therapy (HAART) has helped millions survive the human immunodeficiency virus (HIV). Unfortunately, HIV has a built-in survival mechanism, creating reservoirs of latent, inactive virus that are invisible to both HAART and the immune system.
The study was published in PLoS Pathogens Journal
Some doctoral students at the University of California, Davis, are going far beyond campus labs and academia. They are engaging in practical work at a leading pharmaceutical company, studying air pollution for a state agency and researching malaria in Uganda.

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 vs. bottle feeding in rhesus monkeys

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.
