What is the BEAT-HIV Delaney Collaboratory? The Delaney Collaboratory to Cure HIV-1 Infection by Combination Immunotherapy (BEAT-HIV Collaboratory) is a 


Continued efforts to understand the signaling pathways that modulate the expression of this HIV coreceptor will allow us to test specific inhibitors that may serve to block HIV infectivity. We are grateful to Hiro Moriuchi (Department of Pediatrics, Nagasaki University School of Medicine, Nagasaki, Japan) and Anthony Fauci for their generous gift of the pGL‐CXCR4 constructs.

We were not only able to confirm previously established markers of X4-capability, but also found previously unreported V3 substitutions predictive of X4-capable viruses. Additionally, we found evidence indicating that the V1/V2 region also modulates HIV-2 coreceptor usage. Coreceptor usage and sensitivity to neutralization of HIV-1 and HIV-2. Author: Shi, Yu.

HIV coreceptor tropism is mainly determined by the third hypervariable loop of the viral envelope (gp120-V3) [ 4 ]. coreceptor function, CXCR4–CXCR2 receptor chimeras were tested for the ability to support HIV-1 envelope (env) protein-mediated membrane fusion. Receptor chimeras containing the first and second extracellular loops of CXCR4 supported fusion by T tropic and dual-tropic HIV-1 and HIV-2 strains and binding of a monoclonal antibody to CXCR4, 12G5, that Loetscher, M. et al.

Coreceptor usage of primary human immunodeficiency virus type 1 isolates varies according to biological phenotype. J Virol. 1997 Oct;71(10):7478-87. PMID: 

Both the CCR5 and the CXCR4 co-receptors are seven-trans-membrane (7TM) G protein-coupled receptors. AIDS ResearchTwo papers published in this week's issue of Nature and a third that will appear in the 28 June issue of Science (with independent results from at least one other team reportedly about to be published) report the identification of an essential “coreceptor” for the HIV strains involved in the critical early stages of infection. Human (H-) CCR5 is the primary coreceptor for ENV-mediated fusion by R5 strains of human immunodeficiency virus type 1, whereas mouse (M-) CCR5 lacks this function.

Drugs known as chemokine coreceptor antagonists block the virus from binding to the coreceptor. HIV-1 Coreceptor Tropism, Proviral DNA - The use of CCR5 antagonists requires screening for viral tropism to exclude patients harboring X4 or D/M virus. HIV-1 Proviral DNA tropism test is useful for determination of viral tropism in patients with undetectable HIV-1 viral RNA (virologically suppressed). Last month, another coreceptor, called “fusin,” was reported in Science (10 May, p. 809). The discovery of these two coreceptors--and perhaps others yet to be identified--suggests that HIV may use different molecules to enter the cell at different stages of the disease.

Coreceptor for hiv

Here we report that overexpression of the Oct-2 transcription factor and octamer coactivator BOB.1/OBF/OCA-B, both of which are induced in T cells following T cell receptor … Co-receptors for HIV Entry. The primary cellular receptor for HIV entry is CD4. However, expression of CD4 on a target cell is necessary but not sufficient for HIV entry and infection.

Image (s): (Click to enlarge) 2019-10-01 · A coreceptor probably functions by stabilizing and anchoring the CD4-induced conformation of the Env trimer near the cell membrane to facilitate productive membrane fusion. Thus, according to this model, fortuitous naming of the HIV-1 primary receptor and coreceptor could not be more accurate even in a mechanistic sense.

We conjecture a role for CCR2 as a coreceptor for HIV-1 infection and map the HIV-1 binding site to the amino-terminal part of this receptor. This concurs with results showing that the CCR5 amino terminus is relevant in HIV-1 infection, although chimeric fusion of various extracellular domains shows that other domains are also implicated.
