 AB    Recently, data demonstrating that CD4 is an essential component of the
       receptor for human herpesvirus 7 (HHV-7) as well as for human
       immunodeficiency virus have been accumulating. Since gangliosides and
       phorbol esters are known to induce selective down-modulation of cell
       surface CD4 expression, it might be expected that treatment with these
       agents would interfere with HHV-7 infection of CD4+ T cells. The present
       study, undertaken to verify this possibility, demonstrated that addition
       of monosialoganglioside-GM1 or 12-O-tetradecanoylphorbol 13-acetate
       effectively induced disappearance of CD4 from the cell surface and also
       reduced HHV-7 infectivity, as judged by the CPE on virus-infected cells
       and studies of indirect immunofluorescence, TCID50 and semi-quantitative
       PCR of the HHV-7 genome. Taken together with previous studies, the
       present data strongly suggest that the CD4 molecule is a critical
       component of the receptor for HHV-7.
