Pediatric GI Research Lab
L-R: Shabba Armbrister, Yuying Liu, PhD; J. Marc Rhoads, MD; Tu Mai, MD; and Research Coordinator Nicole Fatheree.
The Pediatric GI Research Lab works to identify the role of probiotics and other gut microbial factors in the regulation of neonatal gut development and inflammatory conditions. The lab team works on mouse models for necrotizing enterocolitis, regulatory T cell deficiency-induced autoimmunity (scurfy mouse), multiple sclerosis, and more. The team specifically explores the immune modulatory mechanism of probiotics and probiotic-modulated gut microbiota and microbiota-associated metabolites. The lab recently expanded its research interest to include the effect of (1) probiotics on gut-brain signals of the neonatal stress model; (2) human breast milk factors on the function of probiotics in healthy newborn mice and autoimmune disorders; (3) probiotic-educated T cell function; and (4) maternal-infant transfer of microbial modified immunity.
This lab is also involved in clinical research projects. This versatile group processes patient samples; analyzes the circulating immune cells, plasma and fecal inflammatory biomarkers, gut permeability markers, and stool DNA isolation for gut microbiota analysis; and assessment of fecal metabolites, as well as quantitation of probiotic colony-forming units.
