FCER1G and atherosclerosis: Moreover, TYROBP and FCER1G were found to be the common hub genes of the 2 genes through the PPI network, and the common mechanism involved may be immunity and lipid metabolism.[42] TYROBP and FCER1G, important immune-related genes, are both involved in the process of atherosclerosis.[43,44] Abnormal lipid metabolism and atherosclerosis are the physiological and pathological basis of MI, of which both indicate the relationship between MI and immune mechanisms.
