HIV infection leads to immune dysfunction through CD4+ T-cell depletion (immunodeficiency) and immune activation (immunosuppression). Studies in long-term nonprogressors indicate that the HIV- specific immune responses in these patients are distinguished by clonal expansions of antigen-specific CD8+ T cells.
Infection requires CD4 protein on the surface of the cell as receptor. • Therefore can only infect CD4+ (“helper") T cells, monocytemacrophages and a few others. 2. Almost all infected cells die within 12 days of infection. 3. Infected CD4 cells make enough virus particles to infect about the same number of new cells (10100
