The chemokine receptor CXCR3 plays an important role in T cell recruitment in various immune responses and autoimmune diseases. CXCR3 overexpression in GC is associated with increased DC and TIL infiltration and improved OS, and thus could be further exploited as a biomarker of favorable prognosis and a therapeutic target in GC. CXCR3 is a chemokine receptor expressed on a wide range of leukocytes, and it is involved in leukocyte migration throughout the blood and lymphatics.
