Gene therapy is where DNA or RNA is transported by a carrier to other cells to provide instructions for replacing damaged genes. This is difficult because the carrier must be able to get the genetic material through the membranes protecting these damaged cells.However, chitosan nanoparticles have recently been used as a carrier and they have shown the ability to safely carry the genetic material to the desired destinations. Chitosan is produced from shrimp shells and does a good job keeping DNA and RNA's large molecules in order to transport them. So far Chitosan has been able to transport this genetic material successfully to the hair in the inner ear of guinea pigs, but it is not yet proven to work in humans.
Gene therapy seems to be the new wave of health care. Its amazing what doctors and scientist can do with technology these days. I wonder if the gene therapy can help cure those who have gone deaf for reasons other than genetics?
ReplyDeleteI think it's interesting that the chiotsan molecules were derived from shrimp shells. It's amazing how we can find use for things that are usually useles.
ReplyDeleteConsidering the equipment used for deaf patients to allow them to hear is extremely expensive this is a great new discovery. Hopefully in the near future a cheaper procedure will be formed that can be used nationwide for patients with hearing problems.
