NLRP3‐Caspase‐1 Axis in Human Adipose Tissue Crown‐Like Structures: A Potential Mediator of Inflammation and the Effects of Bariatric Surgery

Our findings demonstrate that both CLS-forming and single cell macrophage populations in human adipose tissue express NLRP3 and Caspase-1. The study highlights the significance of the NLRP3 inflammasome macrophages in the pathogenesis of adipose tissue inflammation in obesity. The previously reported abundance of CLS in untreated obesity and their reduction after bariatric surgery suggest that the NLRP3-Caspase-1 axis within CLS may serve as an important mediator of the beneficial metabolic effects associated with bariatric surgery.
