On the CT26 and B16F10 tumor models, both local and systemic, CMP enhanced the expression of interferon‐β (IFN‐β), tumor necrosis factor‐α (TNF‐α), and CXCchemokineligand‐10 (CXCL10) proinflammatory cytokines, and promoted tumor invasion of CD8+ T cells, thus showing a good therapeutic effect. Here, CD8A is linked to neoplasm.
