It uses tiny particles that are naturally made by the body to protect and repair damaged joints. This should mean that arthritis is better-treated reducing pain and improving movement of millions. It may also cut the need for painful, complicated and expensive hip and knee replacement operations. The hope centres on microvessicles tiny, fluid-filled bubbles made by the body’s cells. Research at Queen Mary University of London (QMUL) has shown that the thick fluid that bathes the joints in arthritis sufferers is rich microvessicles that are battling against the disease. These microvessicles are packed with a protein called Annexin A1 that protects the cartilage that lines and cushions the joints from the ravages of arthritis. In experiments on arthritic mice, an injection of the microvessicles into the joints reduced cartilage damage. Plus, arthritis was worse in mice that made lower than usual levels of these microvessicles. Excitingly, the protein may even repair damage. This is important because while existing treatments for arthritis can stop further damage to the cartilage, they cannot repair damage that has already been done. It is thought that the microvessicles are made by white blood cells that travel to arthritic joints in a bid to limit damage. Normally, they aren’t present in high enough numbers to stop the disease from taking its course. But if they could be extracted from the blood and injected back into the body in a concentrated form, they could be a powerful new treatment. It might even be possible to arm them with drugs to make them even more effective. Patients could go into hospital as day cases, have blood taken and their microvessicles filtered out, before being injected back into their joints, the journal Science Translational Medicine reported. Mauro Perretti, the study’s lead author, said that, subject to funding, a treatment could be available in just five years’ time. Professor Perretti’s experiments focused on rheumatoid arthritis but he believes people with osteoarthritis could also benefit. Stephen Simpson, medical director of charity Arthritis Research UK, said: ‘Using the body’s own transport system to get therapeutic agents directly into the cartilage holds the promise that we will be able to reduce joint damage more effectively than ever. ‘Healthy and intact joints result in less pain and disability, improving the quality of life for millions of people living with arthritis in the UK.’ SM/IINA
