In another study, simultaneous treatment with anti-PD1 and anti-VEGFR2 in a murine colon cancer model synergistically inhibited tumour growth [73].While PD1 blockade had no impact on angiogenesis, several proinflammatory cytokines were overexpressed, suggesting an effect in T-cell infiltration into tumours and enhanced immune activation. The gene discussed is KDR; the disease is neoplasm.
