Costimulatory and coinhibitory receptors in anti‐tumor immunity
21 Apr 2009
Abstract excerpt
SUMMARY: Despite the expression of antigens by tumor cells, spontaneous immune-mediated rejection of cancer seems to be a rare event. T-cell receptor engagement by peptide/major histocompatibility complexes constitutes the main signal for the activation of naive T cells but is not sufficient to initiate a productive generation and maintenance of effector cells. Full activation of T cells requires additional...
