Downregulation of Renal Hsa-miR-127-3p Contributes to the Overactivation of Type I Interferon Signaling Pathway in the Kidney of Lupus Nephritis.

ABSTRACT: MicroRNAs are involved in the pathogenesis of systemic lupus erythematosus (SLE) and dysregulated in the kidneys of lupus nephritis (LN) patients, but their pathogenic roles in LN are largely unknown. Janus Kinase 1 (JAK1) mediates the activation of the downstream signaling pathways of many inflammatory cytokines, including type I interferon (IFN-I) signaling pathway which is critical to the development of SLE and LN. Thus, JAK1 is a potent therapeutic target for these autoimmune diseases. However, there are few studies demonstrating the dysregulation of JAK1 in autoimmune diseases and the molecular mechanism behind it. In this concise report, we show an inhibitory effect of hsa-miR-127-3p, a microRNA that is downregulated in the renal tissues of LN patients, on IFN-I signaling. We found t
