Understanding Targeted Immunotherapy
What is immunotherapy?
Immunotherapy is a revolutionary approach to cancer treatment that harnesses the power of the immune system to target and attack cancer cells. Unlike traditional therapies such as chemotherapy or radiation, which directly kill cancer cells, immunotherapy works by boosting or modifying the body’s own immune response to better recognize and eliminate cancer cells.
How does targeted immunotherapy work?
Targeted immunotherapy specifically focuses on combating cancer by utilizing various mechanisms. One of the most widely used methods is through monoclonal antibodies. These are designed to target specific molecules on cancer cells, flagging them for destruction by the immune system. Another approach is the use of checkpoint inhibitors, which prevent cancer cells from evading the immune system’s surveillance. Cancer vaccines, on the other hand, stimulate the immune system to recognize and attack cancer cells. CAR-T cell therapy involves engineering a patient’s own immune cells to better target and destroy cancer cells. Additionally, bispecific antibodies are designed to bind to both cancer cells and immune cells, redirecting the immune response towards cancer cells.
Advantages of targeted immunotherapy
Targeted immunotherapy has numerous advantages over traditional cancer treatments. One significant advantage is its specificity, as it directly targets cancer cells while sparing healthy cells. This targeting reduces the risk of side effects commonly associated with chemotherapy, such as hair loss and nausea. Furthermore, targeted immunotherapy has shown improved effectiveness compared to traditional therapies, especially in certain types of cancer. It also provides treatment options for advanced or metastatic cancer when other therapies may no longer be effective. The potential for long-term remission is another remarkable advantage that makes targeted immunotherapy a favorable option for cancer treatment.
Different Types of Targeted Immunotherapy
Monoclonal Antibodies
Monoclonal antibodies are laboratory-produced proteins that are designed to target specific molecules on cancer cells. By binding to these molecules, monoclonal antibodies can activate the immune system to directly destroy cancer cells or inhibit their growth. They can also deliver drugs or radioactive substances directly to cancer cells, increasing the effectiveness of treatment. Some commonly used monoclonal antibodies in cancer therapy include trastuzumab for breast cancer and rituximab for certain types of lymphoma.
Checkpoint Inhibitors
Checkpoint inhibitors are a type of targeted immunotherapy that block proteins known as checkpoints, which cancer cells use to evade immune detection. By inhibiting these checkpoints, the immune system’s ability to recognize and attack cancer cells is enhanced. Checkpoint inhibitors have demonstrated remarkable success in the treatment of various cancers, including melanoma, lung cancer, and bladder cancer. Pembrolizumab, nivolumab, and ipilimumab are examples of widely used checkpoint inhibitors.
Cancer Vaccines
Cancer vaccines work by stimulating the immune system to specifically target cancer cells. Unlike traditional vaccines that prevent infectious diseases, cancer vaccines aim to enhance the immune response against cancer cells. These vaccines can be composed of cancer-specific antigens or genetically modified cancer cells. Cancer vaccines have shown promise in treating certain types of cancer, including prostate cancer and some melanomas. Sipuleucel-T is an FDA-approved vaccine used in the treatment of metastatic prostate cancer.
CAR-T Cell Therapy
CAR-T cell therapy is a groundbreaking approach in which a patient’s own immune cells, known as T cells, are genetically engineered to express a chimeric antigen receptor (CAR) on their surface. This receptor allows the modified T cells to recognize and target specific molecules on cancer cells. Once infused back into the patient, CAR-T cells multiply and attack cancer cells, leading to their destruction. CAR-T cell therapy has shown remarkable results in the treatment of certain blood cancers, including acute lymphoblastic leukemia and non-Hodgkin’s lymphoma.
Bispecific Antibodies
Bispecific antibodies are designed to bind to both cancer cells and immune cells to redirect the immune response towards cancer cells. These antibodies can engage various immune cells, such as T cells or natural killer cells, and bridge them to cancer cells, enhancing their destruction. Bispecific antibodies have shown promising results in the treatment of hematological malignancies and solid tumors. Blinatumomab is an example of a bispecific antibody approved for the treatment of acute lymphoblastic leukemia.
Targeted Immunotherapy Mechanisms
Recognition of cancer-specific antigens
Targeted immunotherapy relies on the recognition of cancer-specific antigens, which are unique molecules present on the surface of cancer cells. Monoclonal antibodies and CAR-T cell therapy specifically target these antigens to trigger the immune response against cancer cells. By targeting cancer-specific antigens, the immune system can selectively attack cancer cells while minimizing harm to healthy cells.
Stimulating the immune system
One mechanism of targeted immunotherapy involves stimulating the immune system to recognize and attack cancer cells. Cancer vaccines, for example, contain cancer-specific antigens that trigger an immune response, leading to the destruction of cancer cells. Checkpoint inhibitors work by releasing the brake on the immune system, allowing it to effectively recognize and eliminate cancer cells.
Direct destruction of cancer cells
Certain targeted immunotherapies directly destroy cancer cells. Monoclonal antibodies can deliver drugs or radioactive substances directly to cancer cells, leading to their destruction. CAR-T cell therapy involves genetically engineering immune cells to express receptors that directly target cancer cells, resulting in their destruction. By directly eliminating cancer cells, targeted immunotherapy aims to eradicate the disease and prevent its recurrence.
