Case Study on AIIMS-SYLLABUS Biology syllabus Biotechnology and its applications
Biotechnology in Medicine – Gene Therapy for Genetic Disorders
One notable application of biotechnology is gene therapy, which holds promise for treating genetic disorders. Let’s explore a case study highlighting the use of gene therapy to treat a specific genetic disorder.
Case Study: Treatment of Severe Combined Immunodeficiency (SCID)
Severe Combined Immunodeficiency (SCID) is a rare genetic disorder characterized by a severely compromised immune system. Patients with SCID are highly susceptible to infections and often have a limited lifespan without treatment. In the early 2000s, a groundbreaking gene therapy trial was conducted to treat SCID caused by a specific mutation.
Patient Background: A young boy named David was diagnosed with SCID caused by a mutation in the IL2RG gene, which is essential for the development of immune cells. David’s immune system was severely compromised, and he was unable to fight off even the mildest infections.
Gene Therapy Approach: The researchers devised a gene therapy approach to treat David’s SCID. The goal was to insert a functional copy of the IL2RG gene into his cells, enabling the production of immune cells capable of combating infections.
Treatment Procedure:
- Collection of Bone Marrow Cells: The researchers collected a sample of David’s bone marrow cells, which contained hematopoietic stem cells (HSCs) capable of giving rise to various blood cells, including immune cells.
- Gene Insertion: In the laboratory, the scientists used a viral vector, typically a modified virus, to deliver a functional copy of the IL2RG gene into David’s HSCs. The viral vector acted as a vehicle to transport the therapeutic gene into the cells.
- Modified Cell Infusion: After successful gene insertion, David’s modified HSCs were infused back into his body through an intravenous injection.
- Cell Integration and Immune Reconstitution: Once inside David’s body, the modified HSCs migrated to his bone marrow, where they began to produce functional immune cells, including T cells, B cells, and natural killer (NK) cells. Over time, these cells helped rebuild his immune system.
Results and Impact: Following the gene therapy treatment, David’s immune system gradually improved, and he became less susceptible to infections. He no longer required isolation or protective measures and was able to lead a more normal life.
This case study highlights the potential of gene therapy in treating genetic disorders. While this specific gene therapy approach was successful for treating SCID caused by a particular mutation, it is important to note that gene therapy is still an evolving field, and its effectiveness can vary depending on the specific disorder, gene, and delivery method.
Further research and clinical trials are ongoing to refine gene therapy techniques, expand its applications, and address challenges such as long-term efficacy and safety. Nevertheless, this case study demonstrates the transformative impact of biotechnology in the field of medicine, offering hope for patients with genetic disorders and potentially paving the way for future advancements in personalized medicine.
