• Interleukin (IL)-17A possesses biological activities to promote vascular endothelial cell migration and microvessel development. To clarify which angiogenic factors are involved in IL-17A-modified angiogenesis-related functions of vascular endothelial cell migration and microtube development or not. The potential contribution of various angiogenic stimulators to in vitro angiogenic activities of IL-17A was assessed with both modified Boyden Chemotaxicell chamber assay and in vitro angiogenesis assay. The addition of a neutralizing antibody (Ab) for hepatocyte growth factor (HGF), basic fibroblast growth factor (bFGF) or vascular endothelial growth factor (VEGF)-A to the upper and lower compartments in a modified Boyden Chemotaxicell chamber significantly attenuated human dermal microvascular endothelial cell (HMVEC) migration elicited by IL-17A. Moreover, IL-17A-induced capillary-like microvessel development in human umbilical vein endothelial cell (HUVEC) and human dermal fibroblast (HDF) co-culture system was significantly impaired by a neutralizing Ab against HGF, bFGF, VEGF-A, cysteine-x-cysteine ligand 8 (CXCL8)/IL-8 or cysteine-x-cysteine (CXC) chemokine receptor (CXCR)-2. Our findings demonstrate the involvement of HGF, bFGF, VEGF-A and/or CXCL8/IL-8, to various degrees, in migration and microvessel development of vascular endothelial cells mediated by IL-17A.
