What is Immunotherapy?
Historical Background
Key Points
12 points- 1.
Immunotherapy uses the body's own immune system to fight cancer and other diseases.
- 2.
There are several types of immunotherapy, including checkpoint inhibitors, T-cell transfer therapy, monoclonal antibodies, and cancer vaccines.
- 3.
Checkpoint inhibitors block proteins that prevent the immune system from attacking cancer cells, allowing the immune system to recognize and destroy them.
- 4.
T-cell transfer therapy involves taking immune cells from the patient, modifying them in a lab to better target cancer cells, and then re-infusing them back into the patient.
- 5.
Monoclonal antibodies are lab-created antibodies that can target specific proteins on cancer cells, marking them for destruction by the immune system.
- 6.
Cancer vaccines stimulate the immune system to recognize and attack cancer cells. Unlike traditional vaccines, they are given after a person has cancer.
- 7.
Immunotherapy can be used to treat a variety of cancers, including melanoma, lung cancer, kidney cancer, and lymphoma.
- 8.
Side effects of immunotherapy can vary depending on the type of treatment and the individual patient, but can include fatigue, skin rash, and inflammation.
- 9.
Immunotherapy is often used in combination with other cancer treatments, such as chemotherapy, radiation therapy, and surgery.
- 10.
The effectiveness of immunotherapy can vary depending on the type of cancer, the stage of the disease, and the individual patient's immune system.
- 11.
Biomarkers are being developed to help predict which patients are most likely to respond to immunotherapy.
- 12.
Research is ongoing to develop new and improved immunotherapy treatments, including personalized therapies tailored to individual patients.

1 topicsFrequently Asked Questions
61. What is Immunotherapy and why is it important for the UPSC exam?
Immunotherapy is a type of treatment that uses the body's own immune system to fight diseases, including cancer. It is important for the UPSC exam, particularly for GS-3 (Science and Technology) and GS-2 (Health), as questions can focus on the types of immunotherapy, their mechanisms, applications, and challenges.
Exam Tip
Remember the different types of immunotherapy and their mechanisms of action for the exam.
2. How does Immunotherapy work in practice?
Immunotherapy works by enhancing the body's natural ability to fight diseases. It doesn't directly attack the cancer like chemotherapy or radiation. Instead, it boosts the immune system to find and attack harmful substances like cancer cells. Different types of immunotherapy work in unique ways to enhance the immune response. For example, checkpoint inhibitors block proteins that prevent the immune system from attacking cancer cells.
3. What are the different types of Immunotherapy?
There are several types of immunotherapy, including:
- •Checkpoint inhibitors
- •T-cell transfer therapy
- •Monoclonal antibodies
- •Cancer vaccines
Exam Tip
Make sure to understand the basic principle behind each type of immunotherapy.
4. What are the key provisions related to Immunotherapy?
The key provisions related to Immunotherapy are:
- •Immunotherapy uses the body's own immune system to fight cancer and other diseases.
- •There are several types of immunotherapy, including checkpoint inhibitors, T-cell transfer therapy, monoclonal antibodies, and cancer vaccines.
- •Checkpoint inhibitors block proteins that prevent the immune system from attacking cancer cells.
- •T-cell transfer therapy involves modifying immune cells in a lab to better target cancer cells.
- •Monoclonal antibodies are lab-created antibodies that target specific proteins on cancer cells.
Exam Tip
Focus on understanding how each provision contributes to the overall effectiveness of immunotherapy.
5. What are the challenges in the implementation of Immunotherapy?
Some challenges in the implementation of immunotherapy include:
- •High cost of treatment, making it inaccessible for many patients in India.
- •Limited research and development in India compared to other countries.
- •Need for specialized infrastructure and trained medical professionals.
- •Potential side effects and immune-related adverse events.
Exam Tip
Consider the socio-economic factors affecting access to advanced treatments like immunotherapy in India.
6. How has Immunotherapy evolved over time?
The idea of using the immune system to fight cancer dates back to the late 19th century. Early forms of immunotherapy, like 'Coley's toxins,' were developed in the 1890s. The discovery of monoclonal antibodies in 1975 revolutionized immunotherapy research. Recent developments include initiatives to promote research and development in India and a focus on affordable treatments.
Exam Tip
