1 METHODS: After whole-blood activation with the gamma(c) cytokines IL-2, IL-7, and IL-15, STAT5 phosphorylation was determined in T cells of de novo kidney transplantation patients treated with tofacitinib/basiliximab (n=5), calcineurin inhibitor (CNI) (cyclosporine A)/basiliximab (n=4) or CNI (tacrolimus)-based immunosuppression (n=6). tofacitinib signal transducer and activator of transcription 5A Homo sapiens
2 In kidney transplantation patients, 7 days after starting tofacitinib/basiliximab treatment, cytokine-induced P-STAT5 was inhibited in CD4(+) T cells (92% for IL-2 activation, 60% for IL-7, and 75% for IL-15), which persisted for the 2-month study period. tofacitinib signal transducer and activator of transcription 5A Homo sapiens
3 CONCLUSIONS: Tofacitinib therapy strongly inhibits gamma(c) cytokine-induced JAK/STAT5 activation, whereas basiliximab suppresses IL-2-stimulated activation only. tofacitinib signal transducer and activator of transcription 5A Homo sapiens
