DNA Vaccination with the Human Immunodeficiency Virus Type 1 SF162
V2 Envelope Elicits Immune Responses That Offer Partial
Protection from Simian/Human Immunodeficiency Virus Infection to
CD8+ T-Cell-Depleted Rhesus Macaques
V2 envelope elicited
lymphoproliferative responses and potent neutralizing antibodies. The
animals were depleted of their CD8+ T lymphocytes and then
challenged intravenously with SHIV162P4. Compared to unvaccinated
animals, the vaccinated macaques had lower peak viremia levels, rapidly
cleared plasma virus, and showed delayed seroconversion.
