Endothelial determinant | Vascular location | Regulation |
---|---|---|
PECAM-1 (CD31) | Throughout vasculature. | Stably expressed |
ICAM-1 (CD54) | Throughout vasculature. | Increased expression during inflammation. |
VCAM-1 (CD106) | Expressed in inflamed vascular endothelium | Increased expression during inflammation. |
E-selectin (CD62E) | Expressed in inflamed vascular endothelium | Increased expression during inflammation. |
P-selectin (CD62P) | Expressed in inflamed vascular endothelium | Activation by agonists can results in rapid transport to cell surface. |
APP | Differentially expressed in vasculature. Increased expression in pulmonary vascular endothelium. Also expressed in heart, liver, and kidney. | Not known. |
PV1 (PLVAP) | Expression in majority of tissues. | Increased expression by VEGF in vitro. |
ACE (CD143) | Throughout vasculature. Increased in the lung capillaries. | ACE activity enhanced by chloride. |
TM (CD141) | Throughout vasculature. Endothelial specific. | Downregulated by factors such as TNF, oxidative stress, hypoxia, C-reactive protein, cAMP, phorbolesters, and oxidized LDL. Upregulated by thrombin, retinoic acid, VEGF, and heat shock. |
