pubmed:abstractText |
Simian immunodeficiency virus (SIV) and human immunodeficiency virus share the property of tropism for CD4-bearing cells. Infection is initiated by a high-affinity interaction between CD4 and conserved domains on the viral envelope glycoprotein. In this report, we demonstrated that SIV had a restricted host range among human CD4+ cells when compared with human immunodeficiency virus type 1 or type 2. This restricted tropism was associated with the inability of the SIV envelope glycoprotein to induce membrane fusion in cells not susceptible to productive exogenous infection by SIV. We conclude that the major route of SIV entry into CD4+ cells is by envelope-mediated direct fusion with the cell and that additional envelope-cell interactions after CD4 binding are required for productive infection.
