New evidence to explain

USA Today (Society for the Advancement of Education),  August, 2006  

New evidence to explain how the body's natural joint lubricant prevents the wear and tear that can lead to osteoarthritis has been uncovered by engineers at Duke University, Durham, N.C. The findings may lead to new methods for treating arthritis. The researchers found that, rather than simply reducing friction, lubricin forms a very thin barrier that repels joint surfaces to prevent their contact.

The researchers also discovered that lubricin, in combination with a second constituent of joint fluid known as hyaluronic acid, produces an even greater protective effect than either of the components alone.
