extravasation of neutrophil
p selectin and integrin act as a receptor for the glycoprotein present on the surface of the plasma membrane of neutrophil.
glycoprotein for integrin and glycoprotein for p selection helps in the movement of neutrophil to the infection site.
neutrophil show roling movement over the innersurface of capillary.
Capillaries innersurface contain endothelial cell. Those endothelial cells contain integrin and p selection that act as receptor for the glycoprotein.
At the site of infection integrin shows a tight adhesion with the glycoprotein ligand present on the surface of glycoprotein.
Infection site releases some signals that stimulate extravasation of neutrophil to the infection site.
