Abstract
In one aspect, the invention provides an HIV envelope heterotrimer comprising at least two different Env glycoprotein monomers. In some heterotrimers, at least two Env glycoprotein monomers are from different HIV isolates, for example, different HIV-1 isolates. Heterotrimers may contain Env glycoprotein monomers from HIV isolates belonging to the same clade or to different clades or both. At least one of the Env glycoprotein monomers in a heterotrimer of the invention may be modified in a way that alters its amino acid composition. In another aspect, the invention provides methods for inducing an immune response in a vertebrate host against HIV or an HIV-infected cell, comprising administering to a vertebrate host a prophylactically or therapeutically effective amount of a composition comprising an HIV envelope heterotrimer.
