A coreceptor tropism test determines whether a patient exclusively harbors R5-tropic virus or has X4-tropic or D/M virus. Patients who exclusively harbor R5-tropic virus can be treated with CCR5 antagonists such as maraviroc (Selzentry ®). CCR5 antagonists block R5 viruses from binding to the CCR5 coreceptor and infecting cells.

( kō'rē-sep'tōr ), A cell surface receptor, which, when bound to its respective ligand, modulates antigen receptor binding or affects cellular activation after antigen-receptor interactions.

Coreceptor

coreceptor (Noun) A cell surface receptor that binds a signaling molecule in addition to a primary receptor in order to facilitate ligand recognition and initiate a biological process, such as entry of a pathogen into a host cell How to pronounce coreceptor? The CD4 coreceptor can only stabilize TCR:MHC II complexes while the CD8 coreceptor can only stabilize the TCR:MHC I complex. Consequently, although there are no important subtypes of TCR itself, differential expression of CD4 and CD8 on different T-cell populations allows functional subpopulations of T-cells to exist. Recent studies have identified the C-X-C chemokine receptor CXCR4 (also named fusin or Lestr) and the C-C chemokine receptor CCR5 as the principal entry cofactors for T-cell-line-tropic and non-T-cell-line-tropic HIV-1, respectively. 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.

2020-11-08 · Orco Odorant receptor co-receptor [ (fruit fly)] Data suggest that Orco interactome, which includes physiologically meaningful candidates, would guide further research on the molecular mechanisms of the insect odorant receptor family.

Thereby, downstream signal transduction may be modulated quantitatively and qualitatively.

The term co-receptor is defined as a type of accessory receptor on the cell surface that does not directly control signaling, but rather indirectly regulates it by binding to the ligand and causing subsequent cascades (Kirkbride, Ray, & Blobe, 2005). A co-receptor implies a molecule that binds to the ligand and supports or stabilizes the formation of a signaling complex. Thereby, downstream signal transduction may be modulated quantitatively and qualitatively.

The proposed model is: 2020-10-13 · a coreceptor of a brassinosteroid receptor BRI1 (7, 8), is able to interact with FLS2 or EFR when flg22 or elf18 is present (9, 10). BAK1, also named SOMATIC EMBRYOGENESIS RECEP-TOR-LIKE KINASE 3 (SERK3), belongs to a SERK subfamily, which contains five members in Arabidopsis. Unlike FLS2 or EFR that possesses a large extracellular domain (ECD) for a BAK1, as a shared coreceptor, plays a key role in multiple PTI pathways, making it an ideal target for microbial effectors.

FcRH1 thus has the potential to serve as an activating coreceptor on B cells.

Tillsammans med T-cellsreceptorn binder denna till MHC klass I-molekylerna, och håller mördar-T-cellen och målcellen bundna tätt ihop när mördar-T-cellen aktiveras.
