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. It is an efficient strategy for plants to trigger much stronger defense responses to eliminate microbes if BAK1 is attacked . Coreceptor tropism, i.e. the type of coreceptor that is used by an HIV-1 virus, has important clinical implications.

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. Several chemokine receptors act as co-factors that allow HIV entry when co-expressed with CD4 on a cell surface. CXCR4.

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. 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.

coreceptor ( plural coreceptors ) ( molecular biology) 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. co·re·cep·tor. ( 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.

Methods: We examined mice with impaired Wnt signaling caused by loss of the Wnt coreceptor Lrp5 in models of lung fibrosis induced by bleomycin or an adenovirus encoding an active form of transforming growth factor (TGF)-β. The identification of LRP4 as a coreceptor for agrin could provide insight into mechanisms of how agrin stimulation leads to AChR clustering. First, bridging agrin and MuSK, LRP4 could transmit signal to MuSK and thus activate intracellular cascades that have been identified, leading to AChR clustering. Second, LRP4 may regulate MuSK activity. 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 ®).
