Research Interest: Microbiome

The Hood Pishchany lab aims to build a community of researchers, educators, and learners partnering to cultivate understanding of the vaginal microbiome from the fundamental biology of its constituent members, the interactions between these members, and their overall impacts on host physiology. We aim to drive women’s health innovation through in-depth exploration of the vaginal microbiome, development of new tools for preclinical testing of microbiome-targeted therapies, and collaboration with academic, industry, community, and clinical partners.

My research interests involve investigation of proinflammatory neuroimmune and epigenetic mechanisms in animal models of developmental neurobiology and neurodegeneration, including (1) alcohol pharmacology, (2) alcohol responsivity and tolerance, (3) adolescent neurodevelopment, (4) cholinergic system and neurocircuitry, (5) microglial function, and (6) Alzheimer’s disease. A major focus of the laboratory is elucidation of neuroimmune and epigenetic mechanisms underlying adolescent binge alcohol-induced disruption of basal forebrain cholinergic neurocircuitry in adulthood. A second major focus of the laboratory is investigation of lasting adolescent binge drinking-induced neuroimmune priming as a novel etiological factor contributing to the onset and progression of basal forebrain neuropathology in Alzheimer’s disease. Our laboratory combines ex vivo and in vivo rodent models of alcohol abuse and Alzheimer’s disease with innovative molecular techniques.

Our lab performs translational investigations of nutritional and microbiota determinants of host-pathogen interactions. We use gnotobiotic techniques (eg. germ free) mice to investigate complex microbe-microbe interactions in the context of host malnutrition, a common but poorly understood global health problem. Specific pathogens we model include Giardia (a ubiquitous parasite with unclear mechanisms of pathogenesis) and other intestinal parasites and multi drug resistant Enterobacterales (eg. Klebsiella). We work with several collaborators to translate findings in experimental models to outcomes in human cohorts. Emerging projects include determinants of host immune responses to mucosal viral infections and vaccines (eg. Polio and SARS-CoV-2).
