Abstract

We sought to determine the relationship between virus-mediated CD4+ T-lymphocyte cytopathicity and viral coreceptor preference among various human immunodeficiency virus type 1 (HIV-1) subtypes in an ex vivo-infected human lymphoid tissue model. Our data show that all R5 HIV-1 infections resulted in mild depletion of CD4+ T lymphocytes, whereas all X4 HIV-1 infections caused severe depletion of CD4+ T lymphocytes regardless of their subtype origin. Thus, at least for the viruses within subtypes A, B, C, and E that were tested, coreceptor specificity is a critical factor that determines the ability of HIV-1 to deplete CD4+ T cells in human lymphoid tissue infected ex vivo.
