Question

L-Selectin, P-Selectin, E-Selectin will all bind to Vascular Addressins.
a) True
b) False

Answer 1

L-Selectin, P-Selectin, and E-Selectin bind to carbohydrate molecules on the surface of endothelial cells in blood vessels, known as vascular addressins.

Step-by-step explanation:

False. L-Selectin, P-Selectin, and E-Selectin are all selectins, which are cell adhesion molecules. They bind to carbohydrate molecules on the surface of endothelial cells in blood vessels. Selectins are involved in the recruitment of leukocytes, or white blood cells, to sites of inflammation or injury. Vascular addressins refer to the carbohydrate molecules on the surface of endothelial cells that selectins bind to. They help mediate the adhesion of leukocytes to blood vessels and play a role in inflammation and immune responses.
