Research Emphasis: gut microbiota, exoelectrogenic bacteria, metagenomics, mucosal immunology, pathology, comparative medicine, translational medicine
Our lab is interested in differences in the composition of the gut microbiota in inbred strains and outbred stocks of mice and rats, factors that drive those differences, and the impact of the resulting enterotypes on rodent models of disease, particularly models of colitis and colitis-associated colorectal cancer. Using rederivation via embryo transfer and fecal microbiota transfer, we modulate the gut microbiota at birth or later in life respectively, to investigate windows of vulnerability for modulation of the gut microbiota. Next-generation sequencing platforms are used to characterize the gut microbiota. Past and ongoing projects have focused on the IL-10 knockout mouse model of inflammatory bowel disease, the Pirc (Apc mutant) rat model of colorectal cancer (CRC), and the Smad3 knockout mouse model of colitis-associated CRC.
We’re also interested in the mechanisms through which certain microbes, such as segmented filamentous bacteria (SFB; see image below), affect the ontogeny of the host immune system. Specifically, certain mucosa-adherent microbes such as SFB (called exoelectrogens) are thought to induce production of electrical currents at the epithelium capable of recruiting electrotactic gut lymphocytes. Ongoing studies in our lab investigate the influence of exoelectrogenic bacteria on development of gut-associated lymphoid tissue during early life, and subsequent susceptibility to immune-mediated diseases and conditions.
Lastly, we collaborate heavily with clinical veterinarians to characterize the gut, respiratory, and dermal microbiota of dogs, cats, horses, cattle, and myriad other species, and examine associations between characteristics of the microbiota that differ between healthy or unaffected individuals and those affected with various conditions.
