Abstract:
Objective:To investigate the effect of curcumin on Th17/Treg cell immune balance in acne mice by regulating the JAK2/STAT3 signaling pathway.Methods:An acne mouse model was established by injecting propionibacterium suspension.The suc-cessfully established mice were randomly separated into the acne group,low(curcumin-L,50 mg/kg curcumin),medium(curcumin-M,100 mg/kg curcumin),high dose(curcumin-H,150 mg/kg curcumin)curcumin groups,and curcumin-H+JAK2/STAT3 pathway activator-olivelin group(150 mg/kg curcumin+1.0 mg/kg colivelin),with healthy mice as the control group,after intervention,the mice were scored for skin lesions;blood was taken from the orbit,ELISA and flow cytometry were applied to detect serum levels of IL-6 and IL-10,and the ratios of Th17 and Treg cells;HE was applied to detect pathological changes in auricle tissue;Western blot was applied to detect the expressions of p-JAK2,p-STAT3,JAK2,STAT3,Treg transcription factor forked transcription factor 3(FOXP3)and Th17 transcription factor retinoic acid related solitary receptor(RORγt)proteins in auricle tissue.Results:Compared with the control group,the pathological damage in the acne group was severe,the skin lesion and pathological scores,IL-6 level,Th17 cells ratio,p-JAK2/JAK2,p-STAT3/STAT3,and RORγt expression were obviously increased,the IL-10 level,Treg cells ra-tio,and FOXP3 expression were obviously reduced(P<0.05);compared with the acne group,the skin lesion and pathological scores,IL-6 level,Th17 cells ratio,p-JAK2/JAK2,p-STAT3/STAT3 and RORγt expression in curcumin-L,curcumin-M,and curcumin-H groups were obviously reduced,the IL-10 level,Treg cells ratio,and FOXP3 expression were obviously increased(P<0.05);com-pared with the curcumin-H group,the skin lesion and pathological scores,IL-6 level,Th17 cells ratio,p-JAK2/JAK2,p-STAT3/STAT3,and RORγt expression in curcumin-H+colivelin group were obviously increased,the IL-10 level,Treg cells ratio,and FOXP3 expression were obviously reduced(P<0.05).Conclusion:Curcumin can improve the immune balance of Th17/Treg cells in acne mice,which may be related to the inhibition of the JAK2/STAT3 signaling pathway.
