Fat cell inflammation emerges as a primary driver of atherosclerosis progression

Adipocyte dysfunction triggers a cascade of systemic inflammation and oxidative stress that accelerates atherosclerotic plaque accumulation, according to findings in atherosclerosis-prone mice fed a Western diet over 12 weeks. Researchers delivered NaKtide, a peptide inhibitor of Na/K-ATPase signaling, directly to adipocytes in Apoe-/- mice, achieving a 67% reduction in atherosclerotic plaque area in the aortic arch and 48% in the aortic sinus. CD68+ macrophage infiltration decreased by 45% and α-SMA+ smooth muscle cell content by 53%, alongside improvements in glucose tolerance and systemic inflammation markers. While complete reversal of established plaques remains therapeutically elusive, this mechanism reveals adipose tissue as an endocrine orchestrator of cardiovascular pathology, positioning fat tissue metabolism as a legitimate intervention target for longevity-focused readers seeking to reshape their cardiometabolic trajectory beyond conventional calorie restriction.
