Altered naive CD4+ T cell homeostasis in myasthenia gravis and thymoma patients.
Journal of neuroimmunology(2019)
摘要
In Myasthenia Gravis (MG) thymic pathologies are often present and thymectomy is used as treatment. By flow cytometry we elucidated alterations of naïve CD4+ T cell homeostasis in MG patients and patients with thymoma. MG patients showed increased absolute numbers of CD31- centralnaïve CD4+ T cells. Thymoma patients displayed a significantly higher fraction of peripheral blood CD31+ thymicnaive T cells. We show an altered naive CD4+ T cell homeostasis in MG patients that might predispose to autoimmunity. Aberrant generation of T cells in thymoma can be detected by an increased frequency of CD31+ thymicnaive CD4+ T cells in the periphery.
