Checkpoint inhibitors are a type of immunotherapy that work by blocking specific proteins, known as checkpoints, which are responsible for regulating the body's immune response. These proteins help to prevent the immune system from attacking healthy cells and tissues. However, cancer cells can exploit these checkpoints to evade detection and destruction by the immune system.
Checkpoint inhibitors work by blocking these checkpoints, allowing the body's immune system to recognize and attack cancer cells more effectively. This type of treatment is particularly useful for certain types of cancer that have been difficult to treat with traditional therapies such as chemotherapy or radiation.
Overall, checkpoint inhibitors are a promising area of research in cancer immunotherapy, offering new hope for patients who may not respond well to other forms of treatment.
