What signal is released by endothelial cells to recruit circulating leukocytes?

#SCPH28 | Zoology

  1. Vesicle-sequestered P-selectins are moved to the cell surface.

  2. Vesicle-sequestered αLβ2 molecules are moved to the cell surface.

  3. Integrins are cleaved from the plasma membrane so that the extracellular domain can bind leukocytes.

  4. Secreted glycoproteins trigger leukocytes to initiate “rolling” motility.
