Inactive CD8 TIL can get reactivated with antibodies targeting PD1, PD‐L1, or CTLA (Duraiswamy et al,2013; Huang et al,2017); however, CD8 TIL are often either scarce or located inside the tumor stroma not reaching the tumor cells (Joyce & Fearon, 2015). The gene discussed is CD274; the disease is neoplasm.
