Immunotherapy to Fight Cancer
Immune checkpoint blocking therapies, or ICBs, help fight cancer by inhibiting the down-regulation of effector T cell activity. Here, two CD8+ T cells (in blue) approach a cancer cell (in brown), while ICB antibodies flow in from the upper right to block interaction between PD-1 and PDL-1. Peptide fragments (in red) are being presented by the cancer cell on its surface in HLA-I (Human Leukocyte Antigen) molecules, which make up
