Vitiligo: A Review of Pathogenesis and Treatments, Including New Therapies on the Horizon.

Summary: Vitiligo is a skin condition affecting about 1% of the world's population, where the immune system mistakenly attacks pigment cells, leaving white patches on the skin. While traditional treatments like light therapy and surgery haven't always been effective, scientists have identified a specific cellular pathway (JAK-STAT) responsible for this immune attack. New drugs called JAK inhibitors are showing exciting results in reversing this process and restoring skin color. While these new treatments are promising, researchers are still determining the safest dosages and long-term effects.
