Virions produced after HIV-1 infection of HTLV-I transformed cells have an expanded tropism that has been attributed to the presence of HTLV-I glycoproteins in the envelope. This report now directly identifies these phenotypically mixed virions by immunogold labelling electron microscopy. Furthermore we estimate there are 2% of these in cell-free supernatant, which represents up to 1 x 10(7) particles/ml from an in vitro infection. HTLV-1 envelope labelling was localised to a single region, suggesting a defined event in packaging of foreign envelope proteins into HIV-1 virus particles.
