New ‘Smart’ Nanotherapeutics Can Deliver Drugs Directly to the Pancreas

ScienceDaily (Jan. 12, 2012) — A research collaboration between the Wyss Institute for Biologically Inspired Engineering at Harvard University and Children’s Hospital Boston has developed “smart” injectable nanotherapeutics that can be programmed to selectively deliver drugs to the cells of the pancreas. Although this nanotechnology will need significant additional testing and development before being ready for clinical use, it could potentially improve treatment for Type I diabetes by increasing therapeutic efficacy and reducing side effects.

The approach was found to increase drug efficacy by 200-fold in in vitro studies based on the ability of these nanomaterials to both protect the drug from degradation and concentrate it at key target sites, such as regions of the pancreas that contain the insulin-producing cells. The dramatic increase in efficacy also means that much smaller amounts of drugs would be needed for treatment, opening the possibility of significantly reduced toxic side effects, as well as lower treatment costs.
