title: The T cell receptor V beta repertoire shows little change during treatment interruption-related viral rebound in chronic HIV infection.
abstract: In this study, changes in plasma virus load, peripheral blood CD4 T cell counts and the T cell repertoire were assessed in eight chronically HIV-infected individuals suspending antiretroviral therapy. Despite rapid increases in virus load and substantial CD4 T cell losses during treatment interruption, no marked changes in the T cell receptor beta chain repertoire were observed. The magnitude of associated T cell repertoire perturbation thus contrasts with that observed during primary HIV infection.
