Abstract
Vitiligo is a depigmenting disease marked by progressive T cell–driven destruction of melanocytes in the skin, hair, and mucosa. While vitiligo is known to be a T cell–mediated autoimmune disease, its triggers have remained poorly understood and treatment options limited. In this issue of the JCI, Kang et al. demonstrated how hyperglycemia exacerbates vitiligo progression through the succinate/SUCNR1 axis. These findings identify succinate as a potential biomarker for disease activity and highlight an independent pathway for targeting in therapeutic intervention. More broadly, the findings linking succinate and glucose metabolism to vitiligo suggest that lifestyle factors could be modified to slow development of vitiligo and other autoimmune diseases linked to succinate.
