The papillomas on those mice treated with OT-1 cells continued to grow (Fig 7A, bottom panel), whereas the papillomas on mice treated with the MusPV1 E6-specific CD8 T cell line stabilized for 3 weeks, shrank significantly by weeks 6–8 (Fig 7A, top panel) and were not apparent by 10 weeks post treatment. The gene discussed is CD8A; the disease is papilloma.
