Nanotechnology is part of the fight against Alzheimer's

Abstract:
There is currently no cure for Alzheimer's disease and its ultimate cause is still unknown. The disease affects an estimated 4.5 million people in the United States alone. That figure is expected to rise dramatically as the population ages, experts predict. Genetic factors are known to be important in causing the disease, and dominant mutations in different genes have been identified that account for both early onset and late onset Alzheimer's. For a number of years, researchers have been working to alleviate neurodegenerative disorders such as Alzheimer's or Parkinson's disease through gene therapy. In this type of treatment, a gene's DNA is delivered to the neurons in individual cells, allowing them to produce their own therapeutic proteins. Gene therapy typically aims to supplement a defective mutant allele (the location of DNA codings on a chromosome) with a functional one. Currently, the most common carrier vehicles to deliver the therapeutic genes to the patient's target cells are viruses that have been genetically altered to carry normal human DNA. These viruses infect cells, deposit their DNA payloads, and take over the cells' machinery to produce the desirable proteins. One problem with this method is that the human body has developed a very effective immune system that protects it from viral infections. Thanks to advances in nanotechnological fabrication techniques, the development of nonviral nanocarriers for gene delivery has become possible. This is attractive due to the potential for improved safety, reduced ability to provoke an immune response, ease of manufacturing and scale up, and the ability to accommodate larger DNA molecules compared to virus-based delivery tools.
