Does interleukin-15 inhibit sodium nitroprusside-induced apoptosis of synovial fibroblasts and vascular endothelial cells?
IL-15 promotes survival of VECs on Matrigel and inhibits SNP-induced apoptosis of endothelial cells. We hypothesize that this mechanism may be relevant to the stabilization of newly formed vascular structures in JRA synovium.
The Mc1r(e) gene stimulates pheomelanin synthesis in the epidermis, dermis and hair follicles. In addition, eumelanin and pheomelanin contents in Mc1r(e)/Mc1r(e) hairs may be influenced by the sex difference.
