Adipocyte fibrosis
WebJul 20, 2024 · Studies point to overlapping and potentially synergistic mechanisms by which obesity and hypertension promote inflammation and cardiac fibrosis. In obesity, adipose tissue expansion is accompanied by an increase in infiltrating immune cells and a shift in macrophage polarization toward a pro-inflammatory activation state. WebJan 3, 2024 · Less fibrosis was associated with adipocyte hypertrophy, reduced pre-adipocyte hyperplasia, and AT dysfunction . Thus, the role of ECM remodeling and fibrosis in human AT dysfunction is stage dependent and likely fat depot specific. This debate is also a reflection of the fact that no consensus has emerged as to how we should define fibrosis.
