Microcapsules Target Arthritic Cartilage

Researchers at Queen Mary University of London have developed a new technique for delivering protein molecules to cartilage affected by osteoarthritis. When delivered in this manner, the protein (CNP) can reduce and possibly repair the damage caused by arthritic inflammation.

The researchers constructed tiny microcapsules, just 2 microns in diameter, with individual layers containing CNP that could release the protein slowly and therefore deliver the treatment in the most effective way.

In experiments on samples of cartilage taken from animals, they showed that the microcapsules could deliver the anti-inflammatory CNP in a highly effective way. The researchers believe that injections of microcapsules could in the future be used to heal damaged cartilage in people with osteoarthritis. The injections could be delivered easily by a GP.
