The upregulation of (C-X-C motif) receptor 3 (CXCR3) and its ligand (C-X-C motif) ligand (CXCL)10 (CXCL10) has been documented in many autoimmune disorders. Many studies have suggested that the CXCL10/CXCR3 axis plays a critical role in the autoimmune process and in β-cell destruction in Type 1 Diabetes (T1D). Serum CXCL10 level "Th1 chemokine" is high in T1D patients, and this suggests that CXCL10 may be a candidate for a predictive marker of T1D. Furthermore, serum CXCL10 levels measurement may be useful to assess the pathophysiology of the disease course in T1D. Blocking of the CXCL10 chemokine expression in newly onset of diabetes seems to be a possible approach for the therapy of T1D. Further studies are needed to investigate interactions between chemokines and cytokines in the pathogenesis of T1D.
