An Inhibitory Role for Human CD96 Endodomain in T Cell Anti-Tumor Responses

Cells, 2023
Immune checkpoint blockade (ICB) therapy involves the inhibition of immune checkpoint regulators which reverses their limitation of T cell anti-tumor responses and results in long-lasting tumor regression. However, poor clinical response or tumor relapse
