In vitiligo, autoreactive T cells attack melanocytes, leading to white spots on the skin. Depigmentation typically recurs upon cessation of treatment, so new therapies are needed for permanent patient relief. Richmond and colleagues reasoned that targeting tissue-resident memory T cells may allow for durable therapy. They observed that T cells from patient lesional samples expressed the receptor for IL-15, an important survival cytokine.
