ABSTRACT
Objective To investigate the changes of regulatory T cells (Tregs) and whether Tregs can modulate the distribution of macrophage subtypes in visceral adipose tissue in the early stage of obesity.Methods After C57BL/6 mice obesity models were successfully established,metabolic parameters and numbers of Tregs and M1/M2 macrophage were measured at 4,10,and 20 weeks.The changes of metabolic parameters and adipose tissue inflammation in obesity mice after rapamycin intervention were evaluated. Results The early-stage obesity models were successfully established.Compared with normal diet mice,high fat diet mice had significantly higher epididymal adipose tissue mass and serum leptin levels(P<0.05).However,there was no statistical difference in blood glucose and insulin levels between these two groups(All P>0.05). Macrophages infiltration in adipose tissue in high fat diet mice gradually increased with time,coincident with decrease in Treg numbers. Increased numbers of Treg,improved metabolic parameters,and decreased ratio of M1/M2 can be seen after rapamycin intervention in mice.Conclusion The decrease of Tregs in the early stage of obesity may contribute to abnormal distribution of macrophage subtypes in visceral adipose.
