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.
