Used in order to try and supplement a defective mutant allele with one that is functional through the insertion of genes into tissues and cells, gene therapy is a type of therapy that has been used with some success, but is still being researched and evaluated in order to try and perfect the process. A number of diseases and illnesses can be treated through this type of therapy.
In short, the process of gene therapy aims to replace abnormal genes that can cause disease with normal genes. Some of the diseases that scientists and researchers have been hoping to tackle through gene therapy include cystic fibrosis, sickle cell anemia, muscular dystrophy, and hemophilia.
The methods used to administer gene therapy can vary. If performed ex-vivo the cells are actually removed from the body and treated before being inserted back into the body. Vivo gene therapy, on the other hand, involves the treatment of the cells with gene therapy while the cells are still in the body.
Although gene therapy is still in its earlier stages, in the grand scheme of things, scientists and researchers are continuing to find a way to make this method successful in the hope that it can be used to successfully treat and prevent a variety of diseases and illnesses in the future. A number of clinical trials involving gene therapy have proven successful.
