The HIV-1 envelope glycoprotein (Env) is the sole neutralizing determinant on the surface of the virus. The Env gp120 and gp41 subunits mediate receptor binding and membrane fusion and are generated from the gp160 precursor by cellular furins. This c

An effective HIV vaccine likely requires the elicitation of neutralizing antibodies (NAbs) against multiple HIV-1 clades. The recently developed cleavage-independent native flexibly linked (NFL) envelope (Env) trimers exhibit well-ordered conformatio

HIV envelope (Env) is a potential vaccine antigen and its N-glycans are part of the epitope of broadly neutralizing antibodies. Here, the authors show that glycosylation of Env from infectious virus closely matches Env from recombinant membrane-bound

Summary: Broadly HIV-1 neutralizing VRC01 class antibodies target the CD4-binding site of Env. They are derived from VH1-2∗02 antibody heavy chains paired with rare light chains expressing 5-amino acid-long CDRL3s. They have been isolated from infe

Broadly neutralizing antibodies targeting HIV Env could potentially be utilized as therapeutics. Here, Steinhardt et al. engineer a trispecific antibody with specificity for the receptor-binding site, a conserved Env glycan patch and the Env membrane

The analysis of site-specific glycosylation of HIV Envelope glycoprotein (Env) is challenging as it contains 25–30 glycosylation sites with multiple glycan forms at each site. Here the authors present a generally applicable mass spectrometry-based

ABSTRACT The filoviruses are etiological agents of life-threatening hemorrhagic fever with high mortality rate and risk of potential outbreak. Among members of this family, the Ebola (EBOV), Sudan (SUDV), and Marburg (MARV) viruses are considered the

A major step toward an HIV-1 vaccine is an immunogen capable of inducing neutralizing antibodies. Envelope glycoprotein (Env) mimetics, such as the NFL and SOSIP designs, generate native-like, well-ordered trimers and elicit tier 2 homologous neutral

Soluble HIV-1 envelope glycoprotein (Env) trimers are under active investigation as vaccine candidates in relevant pre-clinical models. Like SOSIPs, the cleavage-independent native flexibly linked (NFL) trimers are faithful mimics of the Env spike. H

Viral glycoproteins mediate entry by pH-activated or receptor-engaged activation and exist in metastable pre-fusogenic states that may be stabilized by directed rational design. As recently reported, the conformationally fixed HIV-1 envelope glycopro
