Understanding why human immunodeficiency virus (HIV) preferentially infects some CD4(+) CD45RO(+) memory T cells has implications for antiviral immunity and pathogenesis. We report that differential expression of a novel secreted factor, ps20, previously implicated in tissue remodeling, may underlie why
