The human body’s immune system serves as a guardian against diseases by identifying and neutralizing threats like bacteria, viruses, and cancer cells. Scientists are using immunotherapy to enhance the body’s immune response to combat abnormal cells, such as cancer cells. Checkpoint inhibitors are a key component of immunotherapy, blocking molecules that cancer cells use to evade the immune system. Different types of tumors respond differently to immunotherapy, with hot tumors showing more immune activity than cold tumors. Emerging approaches such as CAR-T cell therapy and cancer vaccines offer new possibilities for personalized treatment beyond cancer.Continued research in immunotherapy holds promise for targeted and tailored treatments for a range of conditions, but challenges such as high cost and patient selection remain.
