IFNAR

Interferon-α/β receptor; Interferon-alpha/beta receptor

The interferon-α/β receptor (IFNAR) is composed of two subunits, IFNAR1 and IFNAR2, encoding transmembrane polypeptides. Type-I IFNs, interferon α (IFN-α) and interferon β (IFN-β), act through a shared receptor complex, IFNAR. Binding of type-I IFN to IFNAR1 will robustly activate Janus activated kinase-signal transducer and activator of transcription (JAK-STAT) signaling pathway. Aberrant activation of the type-I IFN response results in a spectrum of disorders called interferonopathies.

Type-I IFN response occurs when IFN-α/β binds to their receptor complex, IFNAR. The ligand-receptor complex is phosphorylated, presumably by pre-associated Janus activated kinases (JAKs) namely tyrosine kinase 2 (TYK2) on IFNAR1 and JAK1 on IFNAR2. The phosphorylated receptors are docking sites for signal transducers and activators of transcription (STAT) factors that dimerise and translocate to the nucleus. STATs 1, 2, 3, 4, and 5 are activated by type-I IFNs in many cell types. Other kinases (e.g., mitogen-activated protein kinases) and transcription factors (e.g., nuclear factor-κB) can also be activated in response to type-I IFNs. Multiple pathways and IFN-regulated genes are activated by IFNs, many of which remain unknown.

    Inhibitor
    VA06 is a derivative of QS-21 (HY-101092A) that retains potent adjuvant activity while significantly reducing toxicity. VA06 self-assembles into flexible worm-like micelles with continuously elongated nanostructures and enhanced drug-loading encapsulation capacity. VA06 induces antigen-specific antibody production, enhances the secretion of TNF-α, IFN-γ and IL-2 in CD4+ and CD8+ T cells, and promotes the expression of immune-related and antiviral-related genes in mature dendritic cells. VA06 does not require liposome formulation, which simplifies production and storage processes. VA06 can be used in the research of varicella-zoster virus infection and Mycobacterium tuberculosis infection.
