Cytotoxic CD8 T lymphocytes are able to recognize malignant cells. Production of neoantigens by tumour cells can lead to peptides which are presented to CD8 T cells bound to MHC I. After antigen recognition, CD8 T cells destroy tumor cells using IFN-ɤ, TNF-α, granzyme B and perforin. However, malignant cells can avoid this elimination by various mechanisms such as the loss of MHC I molecule, induction of anti-inflammatory tumor micro-environment, inhibition of T cell fun…
