Abstract:
Diabetic nephropathy(DN),a severe complication of diabetes,is widely recognized as a primary contributor to end-stage renal disease.Recent studies indicate that the inflammation triggered by Toll-like receptor 4(TLR4)is of paramount importance in the onset and progression of DN.TLR4 can bind to various ligands,including exogenous ligands such as proteins and polysaccharides from bacteria or vi-ruses,as well as endogenous ligands such as biglycan,fibrinogen,and hyaluronan.In DN,the expression or release of TLR4-related ligands is significantly elevated,resulting in excessive TLR4 activation and increased production of proinflammatory cytokines through downstream signaling pathways.This process is closely associated with the progression of DN.Natural compounds are biologically active products derived from natural sources that have advantages in the treatment of certain diseases.Various types of natural compounds,including alkaloids,flavonoids,polyphenols,terpenoids,glycosides,and polysaccharides,have demonstrated their ability to improve DN by affecting the TLR4 signaling pathway.In this review,we summarize the mechanism of action of TLR4 in DN and the natural compounds that can ameliorate DN by modulating the TLR4 signaling pathway.We specifically highlight the potential of compounds such as curcumin,paclitaxel,berberine,and ursolic acid to inhibit the TLR4 signaling pathway,which provides an important direction of research for the treatment of DN.
