The tumour immune phenotype and predicted response to immunotherapy. The inflamed-excluded phenotype is defined through less interaction or contact of cytotoxic immune cells (CD8+ T-cells, natural killer cells) with the tumour epithelial compartment, which may result from a barrier formed from a particular composition of tumour ECM (shown as the orange and green fibres in the illustration above). The ECM barrier reduces immunotherapy response.
