Upregulation of PD‐L1, CD90, PDGFRβ, CD248 and Rgs5 which inhibit CD4+ and CD8+ cytotoxic T‐cell activity was reported in pericytes derived from within tumour microenvironments, which facilitates immunosuppression and eventual immune evasion of tumour cells.62 This evidence concerns the gene CD248 and neoplasm.
