What is Gene Therapy?
Gene therapy is a groundbreaking medical approach that aims to treat or prevent diseases by directly modifying the genes within an individual's cells. This innovative technique holds the potential to address a wide range of genetic disorders, some of which have long been deemed untreatable. By targeting the underlying genetic causes of diseases, gene therapy offers a more precise and effective treatment option compared to traditional methods.The primary purpose of gene therapy is to correct or replace faulty genes responsible for disease development.This can be achieved through various mechanisms, including:
- Gene addition: Introducing a healthy copy of a gene to compensate for a nonfunctional or missing gene.
- Gene editing: Using technologies like CRISPR-Cas9 to directly alter the DNA sequence of a gene, thereby correcting mutations.
- Gene silencing: Inhibiting the expression of a harmful gene that contributes to disease progression.
- Somatic gene therapy: This involves altering the genes in somatic (non-reproductive) cells. The changes made are not inherited by future generations, making it suitable for treating diseases in adults.
- Germline gene therapy: This type targets reproductive cells (sperm and eggs), leading to heritable changes. While it holds promise for preventing genetic disorders in offspring, it raises significant ethical concerns and is currently prohibited in many countries, including the UK.
- Exosomal therapy: A novel approach that utilises exosomes—small vesicles released by cells—to deliver therapeutic genes or proteins. This method enhances the delivery efficiency and reduces potential side effects associated with direct gene transfer.
