Why the study?
Adipose tissue inflammation is proposed to cause insulin resistance and systemic inflammation, but the strength of this relationship in humans is unclear.
Does adipose tissue macrophage burden correlate with insulin resistance and systemic inflammation independent of adipocyte size in humans?
Population
97 volunteers (BMI 20–38 kg/m 2)
Comparison
Correlations and discordant/concordant matching for adipose tissue macrophage burden and adipocyte size
Design
Cross-sectional study
Key result
In 97 volunteers, adipose tissue macrophage burden did not predict insulin resistance, systemic inflammation, or dyslipidemia independent of adipocyte size and body composition.

Suggests adipocyte hypertrophy rather than macrophage infiltration primarily drives metabolic dysfunction; challenges prevailing mechanistic models of insulin.

Does adipose tissue macrophage burden correlate with insulin resistance and systemic inflammation independent of adipocyte size in humans?
Adipose tissue macrophage burden does not independently predict insulin resistance or systemic inflammation when accounting for adipocyte size and body composition.
Jia et al. (2020) conducted a cross-sectional in Insulin resistance and systemic inflammation (n=97). Adipose tissue macrophage (ATM) burden was evaluated on Insulin resistance, systemic inflammation, and dyslipidemia. In 97 volunteers, adipose tissue macrophage burden did not predict insulin resistance, systemic inflammation, or dyslipidemia independent of adipocyte size and body composition.
