[Vaccination and gene therapy with naked DNA]

Abstract:
After injection into the organism, naked DNA causes a slight protein expression. A vaccination is possible, if the DNA encodes for viral or tumor antigens. The DNA proved to be a successful vaccine against virus as well as carcinoma in small animals and safe in humans. However, efficiency has to be increased in the latter. Therefore, combinations of different substances are currently under investigation. Naked DNA is also suitable for gene replacement or gene medicine. However, this is possible only if lowest amounts of proteins cause a biologic effect as done by cytokines, growth hormones etc. DNA is a cheap option for vaccination and treatment, it is easy to transport and therefore of interest for third world countries.

RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...
Cancer Vaccines
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
