Problems solved by technology

Although this method can reflect the level of myocardial inflammation and fibrosis to a certain extent, these indicators often fluctuate greatly in the body, which is prone to individual differences, and the stability of indicators is difficult to fully grasp.

Abstract

The present invention provides a method for establishing a mouse model of autoimmune myocarditis (Experimental Autoimmune Myocarditis, EAM) induced by an autoantigen epitope. The relationship between AchR and autoimmune myocarditis is determined for the first time. Injection of AchR-Freund's complete adjuvant solution, AchR-Freund's incomplete adjuvant solution and immune booster to produce antibodies against cardiomyocyte M2 cholinergic receptors to induce autoimmune myocarditis, and the established model has cardiomyocyte hypertrophy , myocardial fibrosis and cardiac dysfunction. At the same time, with 18 F-FDG PET / CT myocardial metabolic imaging is the core, combined with echocardiography, HE staining of myocardial tissue sections, myocardial Mason staining and myocardial tissue immune antibody special staining to verify the characteristic changes related to the mouse model. Provide a new mouse model for further research on autoimmune myocarditis.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for establishing an EAM mouse model induced by an autoantigen epitope. Background technique [0002] Myocarditis is an inflammatory disease characterized by myocardial inflammatory cell infiltration and non-ischemic necrosis of myocardial cells. The clinical manifestations of myocarditis vary greatly. Mild cases have no obvious clinical symptoms and are easily overlooked. In severe cases, the myocardium is damaged, leading to arrhythmia, cardiogenic shock or sudden death. The etiology of myocarditis can be divided into infectious factors, such as viruses, bacteria, parasites, chlamydia, fungi, protozoa, etc., and non-infectious factors, such as autoimmune diseases, chemical and drug toxins and allergic reactions. [0003] In the past 2 years, autoimmune myocarditis has received high attention due to the use of PD-1 / PD-L1 monoclonal antibody to treat tumors and t...
