Abstract:
:Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease and currently has no effective therapy. The genome-wide analyses indicate that interleukin-1 receptor associated kinase 1 (IRAK1) is associated with the susceptibility of SLE in humans. In the present study, we identified that IRAK1 was overexpressed and hyper-activated in splenic mononuclear cells from B6.MRL-Faslpr/Nju (B6.lpr) mice and peripheral blood mononuclear cells (PBMCs) from SLE patients. Intraperitoneal treatment with a small molecular inhibitor of IRAK1 (IRAK1/4 inhibitor or IRAK-Inh) significantly mitigated inflammatory responses and renal injury in B6.lpr mice. IRAK-Inh treatment or knockdown of IRAK1 by specific siRNA decreased the relative levels of NF-κBp65 phosphorylation in human PBMCs from SLE patients. Therefore, IRAK1 may be a potential target for anti-inflammatory therapy for SLE and other inflammatory diseases.
