Figure Lengend Snippet: (A) Differential transcript expression following in vitro human aortic endothelial cells stimulation with IL-17 versus PBS, IL-17+TNF-α versus PBS, IL-17+IFN-γ versus PBS (p<0.05 for all changes). (B) Direct analysis of venous endothelial cells harvested from psoriasis patients compared to controls show transcript upregulation in intracellular adhesion molecules (VCAM-1, ICAM-1), inflammation (COX-2) as well as chemokines (CXCL10, CXCL1, CX3CL1, CCL3, MCP-1) interleukins and tumor necrosis factors (IL-1β, IL-8, Lymphotoxin beta). (C) Differential endothelial transcript expression in psoriasis over controls stratified by psoriasis severity (control, PASI: ≤ 10, > 10). (D) Endothelial inflammatory activation in psoriatic patients, as assessed by nuclear p65 NFκB localization in the vascular endothelium of brachial vein endothelial cells. Direct immunofluorescence staining of harvested venous endothelial cells (VE-cadherin, green) of psoriasis patients compared to healthy controls show increased p65 NFκB (red) nuclear (DAPI - blue) co-localization (n=6). p<0.05*, p<0.01**. DAPI, 4’,6-diamidino-2-phenylinodle; IL, interleukin; NFκB, Nuclear factor kappa-light-chain-enhancer of activated B cells; PASI, psoriasis area and severity index; PSB, phosphate buffered-saline; TNF, tumor necrosis factor; VEGFA, vascular endothelial growth factor A; vWF, von willebrand factor.
