pubmed:abstractText
Purified whole virus preparations of HIV-1 were produced from supernatants of infected cells and concentrated 5000-fold. After inactivation with formaldehyde, the concentrates were combined with one of three different adjuvants, and used to immunize three groups of three chimpanzees each. The chimpanzees were monitored for HIV-specific humoral and cellular immune responses by ELISA, immunoblot, virus neutralization, delayed-type hypersensitivity, lymphocyte proliferation and antibody-dependent cell-mediated cytotoxicity. Weak and inconsistent responses were observed in animals that received HIV-1 formulated with alum as adjuvant, whereas HIV-1 formulated with incomplete Freund's adjuvant or an experimental adjuvant (BWZL) induced good humoral and cellular immune responses to the virus. The three animals that received HIV-1 with the BWZL adjuvant generated overall the best immune responses; therefore, 2 weeks after the sixth immunization these animals were challenged with infectious HIV-1. Despite the presence of good humoral and cell-mediated immunity, all three immunized animals and a control animal became infected within 4 weeks, as evidenced by repeated isolation of HIV-1 from peripheral blood mononuclear cells and anamnestic antibody responses. The new experimental adjuvant has to be further investigated in other vaccine trials and different animal models.
