Interestingly, OVA-specific CD8+ T cell infiltration is similar between WT and tumours that do not express MHC-I (H2-Kb/DbKO) (Supplementary Fig. 2I, J), highlighting the importance of the tumour microenvironment for recruiting/maintaining antigen-specific CD8+ T cells at the tumour site. Here, CD8A is linked to neoplasm.
