The Entry of Naive T Cells from the Blood into Lymph

question 27

Essay

The entry of naive T cells from the blood into lymph nodes and mucosal lymphoid tissues occurs by a process that involves similar steps and similar adhesion molecules to the process by which leukocytes are recruited into sites of inflammation. Yet naive T cells do not enter tissues at sites of inflammation, but rather, home to lymphoid tissues. Which class of adhesion molecules direct the specific homing of naive T cells to lymphoid tissues?
