We present a patient with haemophilia A showing human immunodeficiency virus type 1 (HIV-1) infection and factor VIII inhibitor in whom a novel T-cell subpopulation, double-negative (CD4-CD8-) T cells bearing T-cell receptor (TCR)-alpha beta, proliferated polyclonally in the peripheral blood. An interleukin-2-dependent T-cell line with a CD4-CD8-TCR-alpha beta+ phenotype was established from the peripheral blood lymphocytes of the patient, and its biological functions were studied. It was found that the CD4-CD8-TCR-alpha beta+ T cells possessed both HLA-unrestricted cytotoxicity and helper function for immunoglobulin production by B cells. In addition, these T cells were found to produce interferon-gamma and interleukin-2 following activation via CD3-TCR complexes. These data demonstrating the multifunction of these newly defined CD4-CD8-TCR-alpha beta+ T cells thus suggest that these cells play an important role in protection against HIV infection. The mechanism of production of factor VIII inhibitor in the present case is also discussed focusing on the CD4-CD8-TCR-alpha beta+ T cells.
