CTLA4-Ig/CD86 interactions in cultured human endothelial cells: effects on VEGFR-2 and ICAM1 expression

Description

Previous studies have reported the presence of CD86 (B7.2) costimulatory molecule on endothelial cells (ECs) and recent data have shown that CTLA4-Ig (abatacept), used as a biological agent in rheumatoid arthritis, interacts with CD86 expressed on different cells involved in synovitis. Therefore, the effects of CTLA4-Ig/CD86 interaction on VEGFR-2 (vascular endothelial growth factor receptor 2) and ICAM1 expression, were evaluated in cultured ECs.
