Checkpoint inhibitor

Okay kiddo, have you ever heard of the immune system? It's like a superhero in your body that helps keep you healthy by fighting off bad germs and viruses.

Sometimes your immune system can get a little confused and start attacking healthy cells in your body, like when you have allergies or autoimmune diseases. But there are special proteins in your body that can help control your immune system and stop it from attacking the wrong things.

A checkpoint inhibitor is a medicine that helps those special proteins do their job even better. It works by putting the brakes on certain cells in your immune system that might be trying to attack healthy cells by mistake. This way, your immune system can focus on fighting the bad germs and cancer cells without hurting your body.

Checkpoint inhibitors are used to help people with certain types of cancer, like melanoma, lung cancer, and bladder cancer. They're like sidekicks to your immune system superhero, helping it fight off the villains and protect your body.
