Thrilled to share my research from Dan Littman's lab at @nyulangone, online today in @Nature. If you are interested in the differentiation of CD4 T cell programs and the mucosal iTreg response, this is for you. #Treg, #ILC3, #Tolerance, go.nature.com/3RCXHkw, A 🧵 /1 CD4 T cell programs govern immune responses, directing inflammation or tolerance. It is widely accepted that classical DCs (cDC) present microbial peptides on MHCII to activate and direct the differentiation of all CD4 T cell programs. Our results challenge this dogma. /2
