L-selectin


SELL

A gene on chromosome 1q23-q25 that encodes l-selectin, a cell surface adhesion/homing receptor required for binding and rolling of leukocytes on endothelial cells, facilitating leukocyte migration into secondary lymphoid organs and inflammation sites. 
Molecular pathology
SELL polymorphisms are associated with various diseases, including IgA nephropathy.

L-selectin

An adhesion molecule that triggers off the interaction between leukocytes and blood vessel endothelium. It is shed from the surface membrane of haematopoietic cells and circulates in the blood as a functional receptor.
