Sentences with phrase «immune checkpoint»

The phrase "immune checkpoint" refers to a mechanism in our immune system that regulates its activity. It acts as a sort of security checkpoint, preventing the immune system from overreacting and attacking our own healthy cells. These checkpoints help maintain a balance, ensuring the immune system responds appropriately while avoiding excessive damage to the body. Full definition
