Increased Fas Antigen in Uremia Accelerates Adhesion of Mononuclear Cells to Endothelial and Sinovial Cells Via Stimulated Hyaluronan Production
2001
Abstract We examined influences of increased soluble Fas (sFas) and hyaluronan in uremia on apoptosis and peripheral blood mononuclear cell (MNC) adhesiveness. Synovocytes, human umbilical cord endothelial cells (HUVEC), human coronary artery smooth muscle cells (CASMC), and MNC were prepared in this study. In cultures of synovocytes, HUVEC, and CASMC, sFas or high molecular hyaluronan was added to media at medium change. After 1 day, Fas-positive cells were calculated by fluorescence-activated cell sorting. Uremic level of sFas enhanced Fas-positive cells in all cell lines (P
