UltraSensKine Human IFN-γ ELISA Kit

Interferon-gamma (IFN-γ) is a dimeric cytokine central to innate and adaptive immunity, primarily produced by activated T cells and natural killer (NK) cells. Structurally, IFN-γ exists as a homodimer, with each subunit comprising six α-helical domains stabilized by intra- and interchain disulfide bonds. It signals through a heterodimeric receptor complex composed of IFNGR1 and IFNGR2, initiating JAK-STAT pathway activation. Post-translational glycosylation at asparagine residues (e.g., Asn25 and Asn97 in humans) enhances its stability and modulates receptor interaction dynamics. Immune Regulatory Roles and Therapeutic Cross-Talk of IFN-γ: Interferon-gamma (IFN-γ) orchestrates multifaceted immune responses, exerting critical antiviral and antitumor defense by inducing cellular antiviral states and enhancing tumor immunosurveillance through upregulation of MHC class I/II expression. It activates macrophages to bolster phagocytosis, reactive oxygen species production, and pathogen clearance, while polarizing CD4+ T cells into Th1 subsets to amplify cell-mediated immunity. Despite its protective roles, IFN-γ exhibits a dual nature in inflammation, where excessive levels contribute to autoimmune disorders (e.g., rheumatoid arthritis, multiple sclerosis) and chronic inflammatory pathologies. Therapeutically, IFN-γ synergizes with proinflammatory cytokines like TNF-α and IL-12 to amplify immune activation, while counteracting the immunosuppressive effects of IL-4 and IL-10, highlighting its pivotal yet complex role in balancing immune defense and inflammatory regulation.
