Stabilized HIV-1 envelope glycoprotein trimers for vaccine use
PURPOSE OF REVIEW To provide an update on the latest developments in the field of HIV-1 antibody-based soluble envelope glycoprotein (Env) trimer design for vaccine use. RECENT FINDINGS The development of soluble native-like HIV-1 Env trimer immunogens has moved the field of antibody-based vaccine design forward dramatically over the past few years with refinement of various stabilizing appro...
متن کاملEnvelope Glycoprotein Trimers as HIV-1 Vaccine Immunogens
The HIV-1 envelope glycoprotein spike is the target of neutralizing antibody attack, and hence represents the only relevant viral antigen for antibody-based vaccine design. Various approaches have been attempted to recapitulate Env in membrane-anchored and soluble forms, and these will be discussed here in the context of recent successes and challenges still to be overcome.
متن کاملMurine Antibody Responses to Cleaved Soluble HIV-1 Envelope Trimers Are Highly Restricted in Specificity.
UNLABELLED Generating neutralizing antibodies (nAbs) is a major goal of many current HIV-1 vaccine efforts. To be of practical value, these nAbs must be both potent and cross-reactive in order to be capable of preventing the transmission of the highly diverse and generally neutralization resistant (Tier-2) HIV-1 strains that are in circulation. The HIV-1 envelope glycoprotein (Env) spike is the...
متن کاملStabilized HIV-1 envelope glycoprotein trimers lacking the V1V2 domain, obtained by virus evolution.
The envelope glycoproteins (Env) are the focus of HIV-1 vaccine development strategies based on the induction of humoral immunity, but the mechanisms the virus has evolved to limit the induction and binding of neutralizing antibodies (NAbs) constitute substantial obstacles. Conserved neutralization epitopes are shielded by variable regions and carbohydrates, so one strategy to increase their ex...
متن کاملSoluble Envelope Glycoprotein Trimers from a CD4-Independent HIV-1 Elicit Antibody-Dependent Cellular Cytotoxicity-Mediating Antibodies in Guinea Pigs.
CD4-independent HIV-1 variants can infect coreceptor-expressing cells lacking CD4. The envelope (Env) glycoproteins on these HIV-1 variants expose a coreceptor binding site that overlaps some CD4-induced (CD4i) epitopes. Reports have demonstrated that CD4i antibodies mediate antibody-dependent cellular cytotoxicity (ADCC). Here we investigated the immunogenicity of soluble Env trimers (sgp140) ...
