Gene therapy research. Researchers working with viral vectors for gene therapy. Gene therapy is the treatment or curing of disease by the insertion of a gene. The gene in question is inserted into an inactivated virus that is targeted at certain cells in the body. The virus infects these cells and incorporates its DNA (deoxyribonucleic acid), including the therapeutic gene, into the DNA of the cell. The gene may replace a faulty or missing gene, or supplement genes already present. Gene therapy could be used to treat genetic diseases such as cystic fibrosis, degenerative diseases such as Alzheimer's, and cancers. Photographed at Transgene, France.
