ABSTRACT
The progression of renal damage in diabetic nephropathy(DN)is closely related to Nod-like receptor protein3(NLRP3)inflammasome activation. The characteristics of NLRP3 inflammasome activation include the changed expression and combination levels of NLRP3, apoptosis-associated speck-like protein(ASC)and pro-caspase-1, the increased expression levels of caspase-1, interleukin(IL)-1β and IL-18 and the excessive release levels of the relative inflammatory mediators. Its molecular regulative mechanisms involve the activation of multiple signaling pathways including reactive oxygen species(ROS)/thioredoxin-interacting protein(TXNIP)pathway, nuclear factor(NF)-κB pathway, nuclear factor erythroid-related factor 2(Nrf2)pathway, long non-coding RNA(lncRNA)pathway and mitogen-activated protein kinases(MAPKs)pathway. In addition, more importantly, never in mitosis aspergillus-related kinase 7(Nek7), as a kinase regulator, could target-combine with NLRP3 at upstream to activate NLRP3 inflammasome. Some extracts of Chinese herbal medicines(CHMs)such as quercetin, curcumin, cepharanthine, piperine and salidroside, as well as Chinese herbal compound prescriptions such as Wumei Pills both could treat NLRP3 inflammasome to ameliorate inflammatory renal damage in DN. Therefore, accurately clarifying the targets of anti-inflammatory CHMs and Chinese herbal compound prescriptions delaying DN progression by targeting the molecular regulative mechanisms of NLRP3 inflammasome activation will be one of the development directions in the future.
