CD30, a member of the tumor necrosis factor (TNF) receptor family, is expressed constitutively on the surface of the human T cell line ACH-2, which is chronically infected with human Immunodeficiency virus type-1 (HIV)-1. We demonstrate that cross-linking CD30 with an anti-CD30-specific monoclonal antibody, which mimics the described biological activities of the CD30 ligand (CD30L), results in HIV expression. CD30 cross-linking does not alter proliferation of ACH-2 cells and the induction of HIV expression is not mediated by endogenous TNFα/β. Furthermore, cross-linking of CD30 leads to NF-κB activation and enhanced HIV transcription. Thus, CD30-CD30L Interactions mediate the induction of HIV expression by a κB-dependent path-way that is Independent of TNF. This mechanism may be Important In the activation of HIV expression from latently Infected CD4+ T cells, especially in lymphoid organs where cell to cell contact is conducive to receptor-ligand interactions.
