Answer #1

In this context, the correct answer is L-selectin. This molecule is a cellular adhesion molecule which is expressed in the surface of leukocytes. Its main function is to provide the initial adhesion in order to allows the migration to the vascular endothelium.

The inactive leukocytes posses high expression on their surface of L-selectin. During the immunological response, the concentration of this molecule will vary in order that the active leukocytes interacts with endothelial cells.
