IL1B and Insulin resistance: Mechanistically, HFD LINK‐A KI mice induce the infiltration of inflammatory factors, including IL‐1β and CXCL16, through the LINK‐A/HB‐EGF/HIF1α feedback loop axis in a self‐amplified manner, thereby promoting the adipose tissue microenvironment remodeling and adaptive thermogenesis disorder, ultimately leading to obesity and insulin resistance.
