Profiling of brachial vein endothelial cells that were collected showed an increase in inflammatory genes (such as IL-1β, CXC motif chemokine 10 (CXCL10), VCAM-1, IL-8, CXC motif chemokine ligand 1 (CXCL1), Lymphotoxin beta, ICAM-1, cyclooxygenase-2 (COX-2), and chemokine CC motif ligand 3 (CCL3)) in individuals with psoriasis compared to the control group. Here, VCAM1 is linked to psoriasis.
