Activation and apoptosis of spleen lymphocytes in patients with viral myocarditis / 中国病理生理杂志

ABSTRACT

AIM: To explore the role of activation and apoptosis of splenic lymphocytes in the development of viral myocarditis (VMC). METHODS: Apotosis and MHC II antigen of splenic lymphocytes were detected in the VMC group (VMC, death, 8 cases) and control group (non-cardiac death, 4 cases) with TUNEL and immunohistochemistry methods.RESULTS: Compared with the control group, the increased expression of MHC II antigen and apoptosis were found in the splenic lymphocytes in the VMC group. CONCLUSION: These results suggest that the abnormality of the apoptosis/activation of splenic lymphocytes may be involved in the pathogenesis of VMC.
