Detailed explanation-1: -This one-time therapy involves the insertion of a functional copy of a missing or faulty gene into a person’s cells by way of a viral or non-viral genetically-engineered vector (delivery vehicle). The goal of this therapy is for the new gene to produce a protein the body couldn’t (previously) produce adequately.
Detailed explanation-2: -The most common gene therapy vectors are viruses because they can recognize certain cells and carry genetic material into the cells’ genes. Researchers remove the original disease-causing genes from the viruses, replacing them with the genes needed to stop disease.
Detailed explanation-3: -Gene therapy techniques allow doctors to treat a disorder by altering a person’s genetic makeup instead of using drugs or surgery. The earliest method of gene therapy, often called gene transfer or gene addition, was developed to: Introduce a new gene into cells to help fight a disease.
Detailed explanation-4: -Gene therapy is a technique that modifies a person’s genes to treat or cure disease. Gene therapies can work by several mechanisms: Replacing a disease-causing gene with a healthy copy of the gene. Inactivating a disease-causing gene that is not functioning properly.
Detailed explanation-5: -There are basically three types of gene therapy: ex vivo, in vivo, and in situ.
