What is Gene Therapy?
Gene Therapy
A method used to treat or prevent diseases by altering the genes inside a person's cells. It aims to fix or replace faulty genes that cause illness, potentially leading to cures for genetic disorders.
Overview
Gene therapy involves introducing, removing, or altering genetic material within a person's cells to treat disease. This technique often uses viruses as vectors to deliver new or modified genes into the patient's cells. By correcting defective genes or providing new functions, gene therapy can address the underlying causes of certain genetic disorders. The process typically starts with identifying a specific gene responsible for a condition, such as cystic fibrosis, where a faulty gene affects lung function. Scientists can then create a healthy copy of this gene and deliver it to the patient's cells. Once inside, the new gene can help produce the necessary proteins that the faulty gene could not, potentially alleviating symptoms or even curing the disease. Gene therapy matters because it represents a shift in how we approach treatment, moving from managing symptoms to targeting the root causes of diseases. This approach has shown promise in clinical trials, with some therapies already approved for conditions like spinal muscular atrophy. As research continues, gene therapy could become a standard treatment for a variety of genetic disorders, significantly improving patient outcomes.
