Abstract:The incidence of diabetes remains high, more and more patients with cardiovascular diseases are involved. Therefore, myocardial fibrosis as one of the physiological and pathological changes leading to cardiac dysfunction in patients with diabetes. Toll-like receptors is one of the most representative receptors in the innate immune response, TLR-4 is a protein closely related to inflammatory response in the TLRs family. In this paper, the effects of TLR-4 inflammatory signaling pathway on myocardial fibrosis in type 2 diabetes were summarized, and the effects of the pathway on myocardial fibrosis in type 2 diabetes were preliminarily expounded from the perspective of inflammatory response.
