Research Interests:

Dr. Brown's laboratory investigates the functional consequences of neuronal communication with epithelial and immune cells in mucosal tissues, particularly those found in the intestine, female reproductive tract and airways. His studies demonstrate that drugs of abuse, which alter peripheral neurotransmission at these sites, can affect protective mechanisms and microbial colonization at mucosal surfaces. Studies are conducted primarily at the molecular, cellular, and tissue levels using an array of cutting-edge methodological approaches. The results of these investigations provide important insights into drug targets for the alleviation of infection, inflammation and pain as well as enhancements in vaccine efficacy and drug delivery.
