TLR4 and diabetic kidney disease: HG conditions in diabetic kidney disease could induce the increased expression of TLR4, cleaved caspase‐1, GSDMD‐NT and secretion of IL‐1β, and IL‐18; pyroptosis in these HG conditions could be partly reversed by TLR4 inhibitors (TAK‐242) and NF‐κB inhibitors (parthenolide).234
