Activity summary

The chemokine receptor CXCR3 also known as CD183 is a protein that plays an important role in immune responses. This receptor is a part of the G protein-coupled receptor (GPCR) family and weighs approximately 41 kDa. CXCR3 is expressed on activated T cells some B cells natural killer (NK) cells and certain subsets of dendritic cells. Its expression is mostly found in inflamed tissues and in conditions where the immune system is active such as infections or autoimmune diseases.

Biological function summary

CXCR3 is involved in directing the migration of immune cells to sites of inflammation. This receptor binds to specific chemokines—CXCL9 CXCL10 and CXCL11—that are produced in response to cytokines like IFN-gamma. CXCR3 does not function as part of a larger protein complex; instead it operates independently facilitating the trafficking and activation of its expressing cells. Its activity is pivotal in immune responses assisting in rapid mobilization and targeting of effector cells to needed areas.

Pathways

CXCR3 is a component of the chemokine signaling pathway which is important for leukocyte chemotaxis. Within this pathway CXCR3 interacts with other receptors and proteins that modulate immune responses such as CXCR4 and CCR5 which also mediate chemotactic migration of leukocytes. Moreover it plays a role in the Jak-STAT signaling pathway impacting gene transcription and cell survival particularly in response to inflammatory signals.

Associated diseases and disorders

CXCR3 is closely associated with autoimmune diseases like multiple sclerosis and rheumatoid arthritis due to its role in inflammation and immune cell recruitment. The receptor is also involved in cancer where its dysregulation can impact tumor growth and metastasis. CXCR3 through its interaction with chemokines like CXCL10 can influence the tumor microenvironment by affecting the infiltration and function of immune cells. Understanding these interactions can provide insights into therapeutic strategies targeting CXCR3 in these conditions.
