    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.
