What is CAR-T Cell Therapy?
Historical Background
Key Points
12 points- 1.
CAR-T cell therapy is a personalized cancer treatment. It uses the patient's own immune cells to fight the disease.
- 2.
The process involves extracting T cells from the patient's blood, genetically modifying them in a lab, and then infusing them back into the patient.
- 3.
The chimeric antigen receptor (CAR) is a key component. It allows the T cells to recognize and bind to specific proteins on cancer cells.
- 4.
CAR-T cell therapy is primarily used for blood cancers, such as leukemia, lymphoma, and multiple myeloma.
- 5.
Common side effects include cytokine release syndrome (CRS) and neurotoxicity. CRS is an inflammatory response that can cause fever, low blood pressure, and difficulty breathing.

Science & TechnologyUPSC Relevance
CAR-T cell therapy is relevant for GS-3 (Science and Technology). It can be asked directly or indirectly. Questions can focus on the technology itself, its applications in cancer treatment, ethical considerations, or government initiatives to promote research in this area.
It's important to understand the basic science behind CAR-T cell therapy, its advantages and disadvantages, and its potential impact on healthcare. In Mains, you might be asked to analyze the challenges in making CAR-T cell therapy accessible in India. In Prelims, factual questions about the components of CAR-T cells or the diseases it treats are possible.
Recent years have seen an increase in questions related to biotechnology and medical advancements.
Frequently Asked Questions
61. What is CAR-T cell therapy, and what are its key provisions relevant for the UPSC exam?
CAR-T cell therapy is a type of immunotherapy where T cells are taken from a patient's blood, genetically modified to target cancer cells, and then infused back into the patient. Key provisions include: * It's a personalized cancer treatment using the patient's own immune cells. * The process involves genetic modification of T cells with a chimeric antigen receptor (CAR). * It is primarily used for blood cancers like leukemia and lymphoma. * Common side effects include cytokine release syndrome (CRS) and neurotoxicity.
