HIV gp120 induces TREM1 expression through TLR–PGE₂ signalling in human monocyte-derived microglia [PDF]
Microglia serve as a long-lived reservoir for HIV in the brain and are resistant to the cytopathic effects of infection. As such, they pose a significant barrier to eradication strategies and contribute to chronic neuroinflammation in people living with ...

Human immunodeficiency virus envelope protein Gp120 induces proliferation but not apoptosis in osteoblasts at physiologic concentrations. [PDF]
Patients with HIV infection have decreased numbers of osteoblasts, decreased bone mineral density and increased risk of fracture compared to uninfected patients; however, the molecular mechanisms behind these associations remain unclear.

Insights from the interfaces of HIV-1 envelope (ENV) trimer viral protein GP160 (GP120-GP41)
The Human Immunodeficiency Virus (HIV-1) type 1 viral protein is a life threatening virus causing HIV/AIDS in infected humans. The HIV-1 envelope (ENV) trimer glycoprotein GP160 (GP120-GP41) is gaining attention in recent years as a potential vaccine ...

HIV envelope antigen valency on peptide nanofibers modulates antibody magnitude and binding breadth
A major challenge in developing an effective vaccine against HIV-1 is the genetic diversity of its viral envelope. Because of the broad range of sequences exhibited by HIV-1 strains, protective antibodies must be able to bind and neutralize a widely ...

Summary: Approximately 50% of the mass of the Envelope (Env) glycoprotein surface subunit (gp120) of human immunodeficiency virus type 1 (HIV-1) is composed of N-linked carbohydrate. Until now, the dogma has been that HIV-1 lacks O-linked carbohydrate on

A mechanistic understanding of allosteric immune escape pathways in the HIV-1 envelope glycoprotein. [PDF]
The HIV-1 envelope (Env) spike, which consists of a compact, heterodimeric trimer of the glycoproteins gp120 and gp41, is the target of neutralizing antibodies. However, the high mutation rate of HIV-1 and plasticity of Env facilitates viral evasion from

Quantifying Anti-HIV Envelope-Specific Antibodies in Plasma from HIV Infected Individuals
Quantifying HIV Envelope (Env)-specific antibodies in HIV+ plasma is useful for interpreting antibody dependent cellular cytotoxicity assay results. HIV Env, the only viral protein expressed on the surface of infected cells, has a native trimeric closed ...

The influence of N-linked glycans on the molecular dynamics of the HIV-1 gp120 V3 loop. [PDF]
N-linked glycans attached to specific amino acids of the gp120 envelope trimer of a HIV virion can modulate the binding affinity of gp120 to CD4, influence coreceptor tropism, and play an important role in neutralising antibody responses.

Evolution of the HIV-1 envelope glycoproteins with a disulfide bond between gp120 and gp41
Background We previously described the construction of an HIV-1 envelope glycoprotein complex (Env) that is stabilized by an engineered intermolecular disulfide bond (SOS) between gp120 and gp41.
