Question

Where are Vascular Addressins found? What do they bind to?

a) Found on endothelial cells, bind to integrins
b) Found on red blood cells, bind to antibodies
c) Found on platelets, bind to clotting factors
d) Found on white blood cells, bind to antigens

Answer 1

Vascular addressins are located on endothelial cells and bind to integrins, playing a crucial role in the immune response by helping white blood cells exit the bloodstream.

Step-by-step explanation:

Vascular addressins are found on endothelial cells and they bind to integrins. These molecules are important in the process where white blood cells move from the bloodstream into tissues. Vascular addressins, such as selectins, interact with integrins on the surface of white blood cells, facilitating their adhesion to the vascular endothelium and subsequent migration out of blood vessels in response to inflammation or tissue injury.
