Table 1 summarizes main cell types involved in immune reaction during colorectal cancer disease
Immune cell type: phenotype and descriptionEffect on colorectal cancer prognosis
CD8+CD45RO+ T cells: memory cytotoxic T cells, associated with a T helper 1 orientationFavorably influencing relapse-free, progression-free and overall survival
FOXP3+CD25+CD4+ T cells: Regulatory T cells with suppressive effect on effector cytotoxic lymphocytesUnfavorably influencing relapse-free and overall survival
CD14+CD163-IL10high M1 macrophages: classically activated macrophagesFavorably influencing prognosis by enhancing Th1-type antitumor immune response
CD14+CD163+IL12high M1 macrophages: classically activated macrophagesUnfavorably influencing prognosis by exerting immunosuppressive effect and enhancing Th2-type response
Lin-HL-ADR-CD11b+CD33+ cells: Myeloid-derived suppressor cellsUnfavorably influencing prognosis by promoting metastatic spread
