In the meantime, MHC‐I blocking could partly hinder the recovery of tumor‐infiltrating CD8+ CTLs (both IFN‐γ+CD8+ CTLs and GZMB+CD8+ CTLs) caused by MARCO‐knockdown TAMs (Figure S9, Supporting Information), which is consistent with the in vitro findings. The gene discussed is CD8A; the disease is neoplasm.
