Estrogen contributes to the sex difference in the occurrence of senescence-related T cells during the development of visceral adipose tissue inflammation

Abstract

The accumulation pattern of adipose tissue differs between the sexes; however, it is unclear whether sex differences exist during the development of adipose tissue inflammation and whether estrogen plays a role. We demonstrated sex differences in immune cells’ subpopulation of visceral adipose tissue. The proinflammatory environment appeared earlier in males than in females. In addition, our results suggest that estrogen plays a role in visceral adipose tissue inflammation, particularly by regulating the appearance of senescence-related T cells.
