JAK3-STAT pathway blocking benefits in experimental lupus nephritis

Lupus nephritis (LN) is a complex chronic autoimmune disease of unknown etiology characterized by loss of tolerance against several self-antigens. Cytokines are known to be central players in LN pathogenesis. The Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway is one important pathway that mediates signal transduction of several cytokines. In this study, we examined the pathogenic role of this pathway and how CP-690,550 treatment influences LN outcome. Six-month-old NZB/NZWF1 mice were divided into two different treatment groups: (1) control animals given vehic... Mehr ...
