RT-qPCR results showed that compared with the normal group, the mRNA expression of IFNA2 was reduced, but the mRNA expressions of TLR2, TLR4, and MyD88 were significantly increased in the rat myocardial tissues of the T2DM group (p < 0.05; Figures 2B,C). Here, MYD88 is linked to type 2 diabetes mellitus.
