Infection by HIV-1 has been associated with perturbations in the TCR V beta repertoire, suggesting the involvement of a superantigen. Among the hallmarks of superantigens is the capacity to delete T cells bearing specific TCR V beta families in the developing thymus. To verify the presence of a superantigen in HIV-1, we analyzed the SCID-hu Thy/Liv TCR V beta repertoire within CD4+CD8+, CD4+CD8-, or CD4-CD8+ thymocytes subsets by flow cytometry using a panel of Abs recognizing about 60% of the… CONTINUE READING
