It takes a village to skew a lymph node

Unconventional T cells (UTCs) play important roles in protecting barrier tissues. In this issue of Immunity, Ataide and colleagues show an additional function for these cells: populating downstream lymph nodes and skewing their cytokine profiles. This process allows tissues to adjust the function of draining lymph nodes through imprinting UTC cytokine production, subsequently influencing the immune responses that are triggered.

Unconventional T cells play important roles in protecting barrier tissues, and they also have the ability to adjust lymph nodes function and influence immune responses.
