  • Shadmehr Demehri, MD, PhD, Erik B. Schiferle, and colleagues determined benign nevi harbor CD4+ T cells that can be activated in situ to reject the nevus. If a novel therapy could block immunosuppressive regulatory T cells, CD4+ cells might prevent progression to melanoma in high-risk patients and enhance immunotherapy.

  • Shawn Demehri, MD, PhD, of the Center for Cancer Research and the Cutaneous Biology Research Center, and team discovered that commensal papillomaviruses cross protect against skin cancer in mice and human tissue—and further findings suggest T-cell–based vaccines may have a role in preventing squamous cell carcinoma.
