PM2.5-induced adipose tissue dysfunction can trigger metabolic disturbances

Exposure to particulate matter ≤2.5 μm in diameter (PM2.5) alters cardiometabolic homeostasis. The reduced oxidative capacity in brown adipocytes and the development of inflammation and insulin resistance in white adipose tissue (WAT) can account for the dysmetabolic setting on PM2.5 exposure. In this forum article, we discuss relevant evidence to highlight a causal connection between PM2.5-induced adipose tissue dysfunction and cardiometabolic disturbances.
