CD62L is a 74-95 kD glycoprotein,also known as L-selectin, LECAM-1, Ly-22 and MEL-14.It is a member of the selectin family and is expressed on the majority of B and naïve T cells,a subset of memory T cells,granulocytes ,subsets of thymocytes and NK cells.CD62L is important in lymphocyte homing to high endothelial venules in peripheral lymph nodes and leukocyte “rolling” on activated endothelium. CD62L also contributes to neutrophil emigration at inflammatory sites.CD62L is rapidly shed from lymphocytes and neutrophils upon activation and the expression levels of CD62L (in conjunction with other markers) hae been used to distinguish naïve, effector and memory T cells.CD62L has been reported to interact with )-glycans presented on CD34, GlyCAM-1, and MadCAM-1.
