Hope you enjoy this recently completed illustration explaining the basic MHC Class I immune process following the phagocytosis of a tumor cell.
The story starts following the phagocytosis and degradation of a tumor cell by a dendritic cell. Further degradation of tumor protein by proteasomes creates 8 to 10 amino acid long antigenic peptides. T cells become activated as a result of the presentation of these antigenic peptides by MHC Class I to the T cell receptor (TCR).
