Resveratrol-decreased hyperalgesia mediated by the P2X receptor in gp120-treated rats

Molecular Pain, 2017
Background Chronic pain is a common symptom in human immunodeficiency virus (HIV)-1 infection/acquired immunodeficiency syndrome patients. The literature shows that the HIV envelope glycoprotein 120 (gp120) can directly cause hyperalgesia by stimulating ...

The V2 domain of HIV gp120 mimics an interaction between CD4 and integrin ⍺4β7.

PLoS Pathogens, 2023
The CD4 receptor, by stabilizing TCR-MHC II interactions, plays a central role in adaptive immunity. It also serves as the HIV docking receptor. The HIV gp120 envelope protein binds directly to CD4.

Molecular evolution of HIV-1 CRF01_AE Env in Thai patients. [PDF]

PLoS ONE, 2011
BACKGROUND: The envelope glycoproteins (Env), gp120 and gp41, are the most variable proteins of human immunodeficiency virus type 1 (HIV-1), and are the major targets of humoral immune responses against HIV-1.

The HIV-1 Env gp120 Inner Domain Shapes the Phe43 Cavity and the CD4 Binding Site

mBio, 2020
The HIV-1 envelope glycoproteins (Env) undergo conformational changes upon interaction of the gp120 exterior glycoprotein with the CD4 receptor. The gp120 inner domain topological layers facilitate the transition of Env to the CD4-bound conformation. CD4

Structural dynamics of HIV-1 envelope Gp120 outer domain with V3 loop. [PDF]

PLoS ONE, 2012
BACKGROUND: The net charge of the hypervariable V3 loop on the HIV-1 envelope gp120 outer domain plays a key role in modulating viral phenotype. However, the molecular mechanisms underlying the modulation remain poorly understood.

Impact of stabilizing mutations on the antigenic profile and glycosylation of membrane-expressed HIV-1 envelope glycoprotein.

PLoS Pathogens, 2023
Recent HIV-1 vaccine development has centered on "near native" soluble envelope glycoprotein (Env) trimers that are artificially stabilized laterally (between protomers) and apically (between gp120 and gp41).

Role of CD4 epitopes outside the gp120-binding site during entry of human immunodeficiency virus type 1 [PDF]

, 1997
CD4 is the primary receptor for human immunodeficiency virus (HIV). The binding site for the surface glycoprotein of HIV type 1 (HIV-1), gp120, has been mapped to the C'-C" region of domain 1 of CD4. Previously, we have shown that a mutant of rat CD4, in

Comparing Antigenicity and Immunogenicity of Engineered gp120 [PDF]

Journal of Virology, 2005
ABSTRACTWe have engineered monomeric gp120 in such a way as to favorably present the conserved epitope for the broadly neutralizing antibody b12 while lowering the exposure of epitopes recognized by some weakly neutralizing and nonneutralizing antibodies.

A hepatic enigma: Pediatric presentation of primary biliary cholangitis

JPGN Reports, EarlyView.
Abstract Primary biliary cholangitis (PBC) is a chronic autoimmune condition characterized by destruction of intrahepatic bile ducts, leading to fibrosis and cirrhosis of the liver. It is an extremely rare pediatric disease with very few pediatric cases reported to date. Here, we report the case of a 14‐year‐old female who presented with elevated liver
