     Thesis Research:
     The balance of intestinal immunity and tolerance is key in infection and
     autoimmunity, as well as in homeostatic responses to ingested antigen and commensal microbes. Lamina propria dendritic cells (lpDC) are antigen-presenting cells that reside below the intestinal epithelium and initiate adaptive immune responses to regulate this balance. There are several distinct subsets of lpDC, however the *in vivo* function of these subsets remains to be elucidated. Using transgenic mice in which we specifically target these subsets for deletion or genetic modification, my research aims to understand the subset-specific functions of lpDC in maintaining steady-state tolerance and in promoting immunity to pathogens.
