Adipocyte senescence
WebCellular senescence has a causal role in adipose tissue dysfunction, presumably through induction of low-grade inflammation and inhibition of adipogenic differentiation resulting in insulin resistance, dyslipidaemia and ultimately development of cardiometabolic disease. WebOct 30, 2024 · This study highlights a phenotype of senescence in adipose tissue of severely obese individuals, which characterises prominently subcutaneous fat depots. Subcutaneous adipose tissue senescence is significantly linked to altered glucose metabolism and body fat distribution.
