Dendritic cells interact with CD4 T cells in intestinal mucosa.

abstract：:The lymphotoxin signaling pathway plays an important role in the homeostasis and function of peripheral and mucosal dendritic cells, and dendritic cell-intrinsic lymphotoxin β receptor expression is required for optimal responses to opportunistic intestinal bacteria. However, it is unknown whether dendritic cell-intri...
