Treatment with Modified Heat Shock Protein Repigments Vitiligo Lesions in Sinclair Swine.

HSP70i is secreted by stressed melanocytes, is associated with human vitiligo lesions, and functionally contributes to a mouse model of vitiligo. Henning et al. report that treatment with a modified version of the protein reversed depigmentation in Sinclair swine, a useful animal model of vitiligo. These studies provide the rationale for testing in human studies.
