Three scientists shared the Nobel Prize in Medicine for pioneering work in studying the immune system.

The winners are: Bruce A. Beutler from the United States, Jules A. Hoffmann from Luxembourg, and Ralph M. Steinman from Canada.

Their work on immune system, where the signaling molecules of antibodies react to microbial invasion, has got a high reward.

Its understanding opens the doors to the invention of new drugs, as well as solving the problem of immune disorders such as asthma, rheumatoid arthritis and Crohn’s disease.

“Their work opens up new possibilities for prevention and treatment of infections, cancer and inflammatory diseases,” – said one of the jurors.
