Activity summary

CXCL9 also known as MIG (monokine induced by gamma interferon) is a small cytokine protein with a molecular weight of approximately 13 kDa. CXCL9 exhibits strong chemotactic properties and is secreted by various cells including endothelial cells macrophages and fibroblasts upon stimulation by interferon-gamma. Its expression primarily occurs in inflamed tissues and is associated with immune responses. Researchers often use tools like a CXCL9 ELISA kit or CXCL9 test to measure its expression levels in biological samples aiding in understanding its role in various conditions.

Biological function summary

This cytokine plays a pivotal role in the immune system by regulating leukocyte trafficking. CXCL9 exerts its function through binding to the CXCR3 receptor attracting T cells towards sites of inflammation or infection. This interaction is significant in mediating immune surveillance and host defense. CXCL9 does not form part of a larger protein complex but its chemokine activity is critical for immune system coordination. Scientific studies often highlight its involvement through CXCL9 function and expression analysis.

Pathways

CXCL9 significantly influences the chemokine signaling pathway and the Th1-type adaptive immune response. Within these pathways it interacts closely with other chemokines like CXCL10 and CXCL11 which also bind to the CXCR3 receptor. These pathways highlight the coordinated mobilization of T cells during immune challenges and inflammation emphasizing how CXCL9 is often examined alongside these related chemokines in research settings.

Associated diseases and disorders

CXCL9 is notably associated with autoimmune diseases such as rheumatoid arthritis and inflammatory conditions like psoriasis. Its elevated expression is often observed in affected tissues contributing to disease pathogenesis through T cell migration and activation. In these contexts CXCL9 is frequently examined alongside other pro-inflammatory cytokines such as interferon-gamma and TNF-alpha which are known to modulate its expression and activity impacting disease progression and therapeutic strategies.
