T cells infiltrating KPAR tumours were alsomore activated, with a higher proportion of effector memory CD8+ andCD4+ T cells (Fig. 4C) andincreased expression of the activation marker CD44 on both CD8+ andCD4+ T cells (Supplementary Fig. 7C-D) as well as the early activation marker CD69 onCD8+ T cells (Supplementary Fig. 7E). The gene discussed is CD8A; the disease is neoplasm.
