Immunotherapy Explained


Immunotherapy is a type of medical treatment that stimulates the body’s immune system to fight diseases, including certain types of cancer. The immune system plays a crucial role in identifying and eliminating abnormal cells, such as cancer cells, but sometimes it needs assistance to recognize and attack them effectively. Immunotherapy can enhance or modify the body’s natural immune response to target and destroy specific cells, such as cancer cells or cells infected with viruses.

There are different approaches to immunotherapy, and they include:

  1. Checkpoint Inhibitors: These drugs block certain proteins on the surface of immune cells or cancer cells, preventing them from inhibiting the immune system’s response. Checkpoint inhibitors can unleash the immune system to attack cancer cells more effectively.
  2. Monoclonal Antibodies: These are laboratory-produced molecules designed to mimic the immune system’s ability to fight off harmful pathogens. In cancer treatment, monoclonal antibodies can be designed to recognize and attach to specific proteins on cancer cells, marking them for destruction by the immune system.
  3. Cancer Vaccines: Cancer vaccines stimulate the immune system to recognize and attack cancer cells. Unlike traditional vaccines that prevent infections, cancer vaccines are designed to treat existing cancers or prevent cancer recurrence.
  4. Adoptive Cell Transfer: This involves removing immune cells (usually T cells) from the patient, genetically modifying them to enhance their ability to target cancer cells, and then reintroducing them into the patient’s body.
  5. Cytokines: These are proteins that regulate the immune response. Immunotherapy may involve administering certain cytokines to boost the immune system’s ability to recognize and destroy cancer cells.

Immunotherapy has shown promising results in treating various cancers, and it is an active area of research and development in the field of oncology. It’s important to note that not all patients or types of cancer respond equally well to immunotherapy, and its effectiveness can vary from person to person. Additionally, immunotherapy can have side effects, and its use is typically tailored to the specific characteristics of the patient’s cancer.
