Amelioration of Neurotoxic Effects of HIV Envelope Protein gp120 by Fibroblast Growth Factor: A Strategy for Neuroprotection [PDF]

Journal of Neuropathology & Experimental Neurology, 2001
Approximately two thirds of patients with human immunodeficiency virus encephalitis (HIVE) show cognitive impairment and neurodegeneration, while one third are cognitively unimpaired and their neuronal populations are preserved. Thus, it is possible that these individuals might have the capacity to produce neurotrophic factors capable of protecting ...

HIV-1 gp120 Protein Activates Cyclin-Dependent Kinase 1, a Possible Link to Central Nervous System Cell Death

Viruses, 2022
Human immunodeficiency virus-1 (HIV-1)-associated neurodegenerative disorder (HAND) is frequently reported in HIV-infected individuals. The gp120 envelope viral protein has been implicated in the pathogenesis of HAND in HIV-1-infected patients; however ...

Surfactant protein D binds to human immunodeficiency virus (HIV) envelope protein gp120 and inhibits HIV replication

Journal of General Virology, 2005
The envelope protein (gp120) of human immunodeficiency virus (HIV) contains highly conserved mannosylated oligosaccharides. These glycoconjugates contribute to resistance to antibody neutralization, and binding to cell surface lectins on macrophages and dendritic cells. Mannose-binding lectin (MBL) binds to gp120 and plays a role in defence against the

Quantifying Anti-HIV Envelope-Specific Antibodies in Plasma from HIV Infected Individuals

Viruses, 2019
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 ...

Sequence-Conserved and Antibody-Accessible Sites in the V1V2 Domain of HIV-1 gp120 Envelope Protein [PDF]

AIDS Research and Human Retroviruses, 2014
The immune-correlates analysis of the RV144 trial suggested that epitopes targeted by protective antibodies (Abs) reside in the V1V2 domain of gp120. We mapped V1V2 positional sequence variation onto the conserved V1V2 structural fold and showed that while most of the solvent-accessible V1V2 amino acids vary between strains, there are two accessible ...

Gp120 on HIV-1 Virions Lacks O-Linked Carbohydrate.

PLoS ONE, 2015
As HIV-1-encoded envelope protein traverses the secretory pathway, it may be modified with N- and O-linked carbohydrate. When the gp120s of HIV-1 NL4-3, HIV-1 YU2, HIV-1 Bal, HIV-1 JRFL, and HIV-1 JRCSF were expressed as secreted proteins, the threonine ...

Canonical Antibodies Adopt Distinct Binding Modes to Recognize Viral Glycan Shields

Advanced Science, EarlyView.
Canonical Y‐shaped antibodies recognize viral glycan shields through adaptive Fab assembly states shaped by glycan organization and somatic hypermutation. Structural analyses ofbroadly neutralizing antibodies VRC35 and VRC36 across glycoproteins of HIV‐1, influenza, SARS‐CoV‐2, and Lassa viruses reveal distinct Fab assembly states, spanning monovalent,

Mass Spectrometric Characterization of a Discontinuous Epitope of the HIV Envelope Protein HIV-gp120 Recognized by the Human Monoclonal Antibody 1331A [PDF]

The Journal of Immunology, 2000
Abstract The characterization of a discontinuous epitope in the C5 region of the HIV envelope protein HIV-gp120, recognized by 1331A, a human mAb, is reported. Regions involved in affinity binding in the HIV-gp120 molecule were identified by epitope excision/extraction methods followed by matrix assisted laser desorption-time of flight ...

Structural insights into tyrosine sulfation of CCR5 by human tyrosylprotein sulfotransferase‐1

The FEBS Journal, EarlyView.
Structural analysis of human tyrosylprotein sulfotransferase‐1 (hTPST1) bound to a CCR5 N‐terminal peptide reveals how hTPST1 recognizes the Tyr3 sulfation site. Structure‐guided models of additional CCR5 sulfation states and full‐length assemblies provide a framework for understanding CCR5 tyrosine sulfation, a post‐translational modification relevant
