9. Gene Therapy
Gene therapy was actually first developed in the 1960s, but it has only come to light recently in the medical field and is being used to help people. Back then, doctors considered that DNA sequences could help patients with certain genetic disorders. In the 1980s, doctors wrote a paper on how a virus could introduce genes into the stem cells for beneficial purposes. Today, we’re able to see a complete blueprint of our own DNA to know which conditions we’re more prevalent to.
Gene therapy first became successful in a four-year-old patient born with severe combined immunodeficiency, which caused her T cells to die off so that she couldn’t fight infections. However, through gene therapy, her body became able to fight these infections off, and she is still alive today. Gene therapy mainly falls into two broad categories: ex vivo and in vivo. Ex vivo is where cells are removed from a patient and used as a vector for new genetic material to be reintroduced. In vivo involves the direct infusion of the vector into the bloodstream or other targeted organs. Keep reading for more medical breakthroughs that changed the healthcare industry.
