Transient T cell receptor beta-chain variable region-specific expansions of CD4+ and CD8+ T cells during the early phase of pediatric human immunodeficiency virus infection: characterization of expanded cell populations by T cell receptor phenotyping.

Abstract excerpt

T cell receptor (TCR) repertoire perturbations are commonly detected in CD8+ T cells during adult primary human immunodeficiency virus (HIV) infection and have been associated with HIV-specific cytotoxic T cell responses. By use of flow cytometry, transient high-level TCR beta-chain variable region-specific expansions of CD4+ and CD8+ T cells were observed more frequently in HIV-infected children than in children...
