Obesity-induced adipose stress leads to the upregulation of ligands for natural cytotoxicity triggering receptor 1(NCR1) on adipocytes, which promotes the activation of NK cells to proliferate, and the release of IFN-γ induces macrophage polarization, which leads to glucose metabolism abnormality and insulin resistance, which suggests that NK cells can exacerbate the metabolic disorders through the cytokine release to exacerbate the symptoms of metabolic diseases [117]. Here, NCR1 is linked to Other metabolic disease.
