- 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.
