AB Cellular CD4 is the primary membrane molecule that binds HIV-1 through
interaction with viral gp120. Membrane glycolipids and cell adhesion
molecules have also been noted to be involved in the interaction of
HIV-1 with cells and in syncytium formation in infected cells. The
purpose of this study was to determine the role of the cell adhesion
molecule CD44 in HIV-1 infection of cells. Both normal blood monocytes
and lymphocytes expressed CD44 as determined by flow cytometry using the
anti-CD44 antibody A3D8. Anti-CD44 monoclonal antibodies A3D8, A1G3, and
5F12 [ascites, purified IgG, and F(ab')2] inhibited infection of
monocytes and peritoneal macrophages with HIV-1-BaL and HIV-1-ADA, but
had no effect on HIV-1-IIIB infection of mitogen-stimulated lymphocytes,
or cells of a T lymphocyte line. CD44 monoclonal antibodies were not
toxic for monocytes, and the observed inhibitory effect of CD44
monoclonal antibodies was not dependent on complement. These results
suggest that CD44 may be a determinant of HIV-1 infection of mononuclear
phagocytes in vitro.
