ABSTRACT
Objective:
To investigate the effects of TLR4 knockout on immune cells and adipokines in mouse visceral adipose tissue.Methods:
Cells were isolated from the spleen and epididymal adipose tissue of 20-week-old male wild type mice C57BL/6 and TLR4-/-.The expression of F4/80,CD11b,CD11c,CD3,CD4 and CD8 in these cells were analyzed by flow cytometry.The expression of IL-6,HMGB1,TNF-α,adiponectin and resistin in epididymal adipose tissue were detected by qPCR.Results:
Compared with wild type C57BL/6 mice,the percentage of M1 macrophage which marked F4/80+CD11b+CD11c+ in spleen and epididymal adipose tissue of TLR4-/-mice increased(P<0.05) greatly,while that of M2 macrophage which marked F4/80+CD11b+CD11c-was decreased(P<0.05)significantly.This trend was more remarkable in epididymal adipose tissue than in spleen(P<0.05).In epididymal adipose tissue,the percentage of CD4+T cells decreased but that of CD8+T cells increased in TLR4-/-mice.Moreover,the high-level expressions of IL-6,HMGB1,resistin were found in epididymal adipose tissue of TLR4-/-mice.However,the expressions of TNF-α and adiponectin decreased obviously.Conclusion:
TLR4 knock-out could lead to a disorder in adipokine and immune cells in visceral adipose tissue.
