Conformational states of a soluble, uncleaved HIV-1 envelope trimer
HIV-1 envelope spike [Env; trimeric (gp160)3, cleaved to (gp120/gp41)3] induces membrane fusion, leading to viral entry. It is also the viral component targeted by neutralizing antibodies. Vaccine development requires production, in quantities suitable for clinical studies, of a recombinant form that resembles functional Env. HIV-1 gp140 trimers the uncleaved ectodomains of (gp160)3 from a few ...

متن کاملStable, uncleaved HIV-1 envelope glycoprotein gp140 forms a tightly folded trimer with a native-like structure.
The HIV-1 envelope spike [trimeric (gp160)3, cleaved to (gp120/gp41)3] is the mediator of viral entry and the principal target of humoral immune response to the virus. Production of a recombinant preparation that represents the functional spike poses a challenge for vaccine development, because the (gp120/gp41)3 complex is prone to dissociation. We have reported previously that stable HIV-1 gp1...
متن کاملEngineering and Characterization of a Fluorescent Native-Like HIV-1 Envelope Glycoprotein Trimer.
Generation of a stable, soluble mimic of the HIV-1 envelope glycoprotein (Env) trimer on the virion surface has been considered an important first step for developing a successful HIV-1 vaccine. Recently, a soluble native-like Env trimer (BG505 SOSIP.664) has been described. This protein has facilitated major advances in the HIV-1 vaccine field, since it was the first Env immunogen that induced...
