简要总结
The purpose of this study is to assess the level of CD4 and CD8 T cell activation in an observational cohort study of HIV-1 patients, virosuppressed on combined antiretroviral therapy (< 50 copies/ml) for at least 2 years and to focus on two factors that could participate in this activation: cytomegalovirus infection and auto-immune disorders.
详细描述
T cell activation plays a central role in HIV pathogenesis and is highly correlated to disease progression even in HIV patients virosuppressed on combined antiretroviral therapy since years. The mechanisms underlying this activation in virosuppressed patients are poorly understood. Identifying some factors involved in immune activation that can be targeted by therapies could optimize the treatment of HIV patients. The purpose of this study is to assess the level of CD4 and CD8 T cell activation in an observational cohort study of HIV-1 patients, virosuppressed on combined antiretroviral therapy (< 50 copies/ml) for at least 2 years and to focus on two factors that could participate in this activation: cytomégalovirus infection and auto-immune disorders.
