Researchers at the Albert Einstein College of Medicine, a part of Yeshiva University, are using novel nanoparticles to significantly speed up the healing of wounds. They discovered that the naturally produced fidgetin-like 2 (FL2) enzyme slows down the migration of cells as they travel toward a wound site. To counteract this process, the investigators developed a silencing RNA (siRNA) drug that inhibits the gene responsible for the production of FL2.
In order to actually deliver the siRNA into the interior of cells before degrading, the researchers encapsulated it in specially designed nanoparticles that keep their cargo fresh and intact before reaching the cell and letting it flow out.
