Introduction
PD-1 inhibitors, also known as immune checkpoint inhibitors, have revolutionized cancer treatment. These drugs work by blocking the PD-1 protein, which is expressed on the surface of T cells and regulates the immune response. By inhibiting PD-1, PD-1 inhibitors allow T cells to more effectively recognize and attack cancer cells.
Cancers Treated with PD-1 Inhibitors
PD-1 inhibitors have been approved for the treatment of a wide range of cancers, including:
Types of PD-1 Inhibitors
There are several types of PD-1 inhibitors currently available, including:
Mechanism of Action
PD-1 inhibitors work by blocking the PD-1 protein on the surface of T cells. PD-1 is a checkpoint protein that regulates the immune response. When PD-1 binds to its ligand, PD-L1, it sends a signal to the T cell to stop attacking. By blocking PD-1, PD-1 inhibitors prevent this signal from being sent, allowing T cells to more effectively recognize and attack cancer cells.
Benefits of PD-1 Inhibitors
PD-1 inhibitors offer several benefits over traditional cancer treatments, including:
Side Effects
PD-1 inhibitors can cause side effects, including:

FAQs
Call to Action
If you have been diagnosed with a type of cancer that may be treated with PD-1 inhibitors, talk to your doctor to learn more about this revolutionary treatment option. PD-1 inhibitors have the potential to significantly improve the quality of life and extend the lives of cancer patients.
