Immune checkpoint inhibitor

Immune checkpoint inhibitors are a type of cancer treatment that help the immune system recognize and attack cancer cells. Normally, the body has mechanisms (checkpoints) that prevent immune responses from being too strong, which can keep the immune system from effectively targeting tumors. Checkpoint inhibitors block these mechanisms, allowing the immune system to better identify and destroy cancer cells. This approach has shown significant success in various cancers, leading to longer survival rates and improved outcomes for many patients. Examples include drugs like pembrolizumab and nivolumab, which target specific checkpoints on immune cells.
