Structural Constraints at the Trimer Apex Stabilize the HIV-1 Envelope in a Closed, Antibody-Protected Conformation

open access: yesmBio, 2018
The human immunodeficiency virus type 1 (HIV-1) envelope (Env) trimer evades antibody recognition by adopting a closed prefusion conformation. Here, we show that two conserved tyrosines (Y173, Y177) within the second variable (V2) loop of the gp120 Env ...

Guanylate-Binding Proteins 2 and 5 Exert Broad Antiviral Activity by Inhibiting Furin-Mediated Processing of Viral Envelope Proteins

open access: yesCell Reports, 2019
Summary: Guanylate-binding protein (GBP) 5 is an interferon (IFN)-inducible cellular factor reducing HIV-1 infectivity by an incompletely understood mechanism.

Recombinant Flag-tagged E1E2 glycoproteins from three hepatitis C virus genotypes are biologically functional and elicit cross-reactive neutralizing antibodies in mice [PDF]

open access: yes, 2018
Hepatitis C virus (HCV) is a globally disseminated human pathogen for which no vaccine is currently available. HCV is highly diverse genetically and can be classified into 7 genotypes and multiple sub-types. Due to this antigenic variation, the induction

Monoclonal anti-envelope antibody AP33 protects humanized mice against a patient-derived hepatitis C virus challenge [PDF]

open access: yes, 2016
End-stage liver disease caused by hepatitis C virus (HCV) infection is a major indication for liver transplantation. However, immediately after transplantation the liver graft of viremic patients universally becomes infected by circulating virus ...

Herpes Simplex Virus 1 Envelope Cholesterol Facilitates Membrane Fusion

open access: yesFrontiers in Microbiology, 2017
Methyl beta-cyclodextrin (MβCD) treatment of herpes simplex virus 1 (HSV-1) reduced envelope cholesterol levels and inhibited viral entry and infectivity in several cell types, regardless of the dependence of entry on endocytosis or low pH. Viral protein

Cell type-specific delivery by modular envelope design

open access: yesNature Communications, 2023
The delivery of genetic cargo remains one of the largest obstacles to the successful translation of experimental therapies, in large part due to the absence of targetable delivery vectors.

Understanding the process of envelope glycoprotein incorporation into virions in simian and feline immunodeficiency viruses [PDF]

open access: yes, 2014
The lentiviral envelope glycoproteins (Env) mediate virus entry by interacting with specific receptors present at the cell surface, thereby determining viral tropism and pathogenesis.

Envelope-receptor interactions in Nipah virus pathobiology. [PDF]

open access: yes, 2007
Nipah (NiV) and Hendra (HeV) viruses are members of the newly defined Henipavirus genus of the Paramyxoviridae. Nipah virus (NiV) is an emergent paramyxovirus that causes fatal encephalitis in up to 70% of infected patients, and there is increasing ...

HIV-1 Diversity in the Envelope Glycoproteins: Implications for Viral Entry Inhibition

open access: yesViruses, 2013
Entry of HIV-1 into a host cell is a multi-step process, with the viral envelope gp120 and gp41 acting sequentially to mediate the viral attachment, CD4 binding, coreceptor binding, and fusion of the viral and host membranes.

Evolution of replication efficiency following infection with a molecularly cloned feline immunodeficiency virus of low virulence [PDF]

open access: yes, 2002
The development of an effective vaccine against human immunodeficiency virus is considered to be the most practicable means of controlling the advancing global AIDS epidemic.
