This study was stimulated by the clinical observation of a rapid response of a chilblain lupus patient to treatment with JAK1/2-kinase inhibitor ruxolitinib. We investigated the in vivo expression of phospho-JAK2 in CLE skin samples as well as the immunomodulatory in vitro effect of ruxolitinib in cultured immortalized keratinocytes and in a 3D human epidermis model (epiCS). Our results demonstrate that ruxolitinib significantly decreases the production of CLE-typical cytokines (CXCL10, CXCL9, MxA) and might be a promising drug for future clinical studies in patients with CLE and related autoimmune skin diseases.
本研究受冻疮样狼疮患者对JAK1/2激酶抑制剂鲁索替尼治疗产生快速反应的临床观察启发。我们研究了CLE皮肤样本中磷酸化JAK2的体内表达,以及鲁索替尼在培养的永生化角质形成细胞和三维人表皮模型(epiCS)中的体外免疫调节作用。我们的结果表明,鲁索替尼显著降低了CLE典型细胞因子(CXCL10、CXCL9、Mx A)的产生,可能是未来用于CLE及相关自身免疫性皮肤病患者临床研究的一种有前景的药物。
