Immune checkpoint blockade therapies have changed the paradigm of cancer therapies. Reseachers performed in vivo screening for anti-PD-1 therapy across 23 syngeneic tumor models and found that CT-26 and Colon 26, which are murine colorectal carcinoma derived from BALB/c mice, showed different sensitivity to anti-PD-1. In vivo studies for anti-PD-1 antibody across 23 syngeneic tumor models were performed by Medicilon.
