T Cells in Hair (IMAGE) Dartmouth-Hitchcock Medical Center Caption Image of T cells in hair follicles of mice with vitiligo. Dartmouth researchers have shown that these T cells also reside in vitiligo-affected skin, where they can fight melanoma tumors, serve a critical role in protecting against future tumors, and provide long-term immunity to melanoma. Generation of such cells in humans may be used as future cancer therapies. Credit Yina Huang Usage Restrictions This photo is copyrighted and may not be reproduced without permission.
