Question

Quizplus · Accepted Answer

L-selectin is expressed abundantly on naive T cells, but not effector T cells, and binds to peripheral lymph node addressin (PNAd) on high endothelial venules in lymph nodes
This adhesive interaction is required for naive T cell migration from blood into lymph nodes, a first step in the initiation of cell-mediated immune responses.
