The expression pattern of CD8+ T cells overlapped and they concluded that ILD was induced by nivolumab‐activated peritumoral CD8+ T cells.24 Laubli et al. also revealed a similarity between T cells in irAEs lesions and tumor infiltrating lymphocytes (TILs).25 These findings suggest that ILD reflects the infiltration of T cells with a specificity similar to tumor‐infiltrating T cells. The gene discussed is CD8A; the disease is neoplasm.
