CXCL9 and vitiligo: Collectively, ROS accumulation following oxidative stress induces the production of chemokines, thus promoting the infiltration of T cells trafficking into vitiligo lesions, providing insight into the importance of the CXCL9/CXCL10-CXCR3 axis that orchestrates the migration of immune cells involved in the progression and maintenance of vitiligo, indicating potential targets for treating vitiligo.
