L. plantarum facilitates wound healing in diabetic rats. SD rats were intraperitoneally injected with 60 mg/kg STZ to establish a diabetic rat model. The skin wounds (1.3×1.3cm) were made using a scissor on the midback of rats at 72h after STZ administration. The rats were treated with either 10 mg/kg of MCC950 or 2×106 CFU/mL of L. plantarum for 7 or 14 days. (A and B) photographs of wounds were taken to calculate the healing rate. (C) Pathological changes of the ulcer tissue were analyzed by HE staining (scale bar, 50 μm). (D and E) The levels of IL-1β and IL-18 were detected by ELISA. (F) The expression of NLRP3, ASC, Caspase-1p20, and GSDMD-N was detected by Western blot. ***P<0.001 vs control; #P<0.05, ##P<0.01, ###P<0.001 vs STZ.
