Abstract

HIV-1 Env ectodomain trimers stabilized in a prefusion mature closed conformation and methods of their use and production are disclosed. In several embodiments, the HIV-1 Env ectodomain trimers and/or nucleic acid molecules can be used to generate an immune response to HIV-1 in a subject. In additional embodiments, the therapeutically effective amount of the HIV-1 Env ectodomain trimers can be administered to a subject in a method of treating or preventing HIV-1 infection.
