What exactly is gene therapy?
Gene therapy involves altering the genes inside your body’s cells in an effort to treat or stop disease. Genes contain your DNA — the code that controls much of your body’s form and function, from making you grow taller to regulating your body systems. Genes that don’t work properly can cause disease.
What is an example of gene therapy?
Gene therapy is the introduction of genes into existing cells to prevent or cure a wide range of diseases. For example, suppose a brain tumor is forming by rapidly dividing cancer cells. The reason this tumor is forming is due to some defective or mutated gene.
What are types of gene therapy?
There are two types of gene therapy treatment: Somatic cell gene therapy and germline therapy. Somatic cell gene therapy involves obtaining blood cells from a person with a genetic disease and then introducing a normal gene into the defective cell (Coutts, 1998).
Why is gene therapy bad?
The idea of germline gene therapy is controversial. While it could spare future generations in a family from having a particular genetic disorder, it might affect the development of a fetus in unexpected ways or have long-term side effects that are not yet known.
Why was gene therapy created?
The goal was to replenish Ashanti’s blood cells with ones that could produce ADA. Gene therapy had the advantage that the cells originated from Ashanti so there was no risk of rejection.
Why are viruses used in gene therapy?
Certain viruses are often used as vectors because they can deliver the new gene by infecting the cell. The viruses are modified so they can’t cause disease when used in people. Some types of virus, such as retroviruses, integrate their genetic material (including the new gene) into a chromosome in the human cell.
Who invented gene therapy?
French Anderson, MD, was “dubbed ‘the father of gene therapy’ after a team he led in 1990 cured a hereditary disease of the immune system in a 4-year-old girl.” That’s not quite the way it happened.
What is the difference between gene therapy and cell therapy?
Gene therapy involves the transfer of genetic material, usually in a carrier or vector, and the uptake of the gene into the appropriate cells of the body. Cell therapy involves the transfer of cells with the relevant function into the patient.
HOW WAS gene therapy used in the 1990 trials?
Researchers drew blood from both girls, inducing the T cells from their blood to replicate in culture. Retroviral vectors infused with functional ADA genes were transferred into the cultured T cells. The gene-corrected T cells were reinfused back into the girls about 12 days after blood was drawn.

What diseases are treated by gene therapy?
Gene therapies for sickle cell disease, beta-thalessemia, and Fanconi anemia all show promise and are at various stages of clinical trials. Among the most developed gene therapies, Learn more about available treatments and others on the horizon for LCA, retinitis pegmentosa, choroideremia and more.
What is gene therapy and how is it delivered?
Gene therapy products work by introducing genetic material into the nucleus of the cell . In order to introduce the genetic material, scientists need a delivery system that can transport the gene, nuclease, or short hairpin RNA (shRNA) to the nucleus of a human cell. The vehicle that carries this genetic material is known as a vector.
