CXCR3 is a G protein-coupled receptor (GPCR) for interferon-inducible chemokines CXCL9, CXCL10, and CXCL11. It is expressed on various immune cells and plays critical roles in chemotaxis, cell activation, and inflammatory responses. In the nervous system, CXCR3 contributes to neuroinflammation in neurodegenerative diseases.
CXCR3 is a typical 7-transmembrane GPCR:
CXCR3 mediates directed migration of:
CXCR3 signaling induces:
CXCR3 on autoreactive T cells mediates their migration into the CNS:
CXCR3-mediated neuroinflammation contributes to pathology:
CXCR3 signaling in PD:
In motor neuron disease:
CXCR3 antagonists are being developed for:
The study of Cxcr3 Protein has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
