摘要:
This invention provides methods for eliciting an immune response in a subject comprising administering to the subject as part of a regimen (i) more than one dose of a nucleic acid prime, and (ii) more than one dose of a protein boost composition, wherein each dose of the nucleic acid prime is administered to the subject at a first predefined interval and each dose of the protein boost composition is administered to the subject at a second predefined interval, and wherein the protein boost composition comprises a prophylactically or therapeutically effective dose of (a) a trimeric HIV-1 gp140 protein complex, or (b) a superparamagnetic particle and a trimeric HIV-1 gp140 protein complex so affixed thereto as to permit recognition of the complex by a subject's immune system. The invention also provides methods for prophylactically or therapeutically treating HIV-1 infection in a subject. The invention further provides uses of a nucleic acid prime and a protein boost composition for the manufacture of separate coadministerable medicaments to be administered to a subject.
摘要:
This invention provides a protein comprising (a) a first polypeptide which comprises consecutive amino acids, the sequence of which corresponds to the sequence of a modified gp120 envelope polypeptide portion of a gp140 envelope of (i) an HIV-I KNH1144 isolate, or a quasi-species thereof, or (ii) an HIV-I 5768.4 isolate, or a quasi-species thereof; and (b) a second polypeptide which comprises consecutive amino acids, the sequence of which corresponds to the sequence of a modified gp41 ectodomain polypeptide portion of the gp140 envelope of (i) the HIV-I KNH1144 isolate or such quasi-species thereof, or (ii) the HIV-I 5768.4 isolate or such quasi-species thereof. This invention also provides nucleic acids encoding such proteins, vectors, host cells and compositions thereof. Also provided are trimeric complexes (‘trimers’) of these proteins and methods of using such trimers to combat HIV-I infection.
