"The puzzle about the ancestral function of toll-receptors has been solved. For more than 25 years, researchers from medicine and biology have been studying toll-receptors, revealing functions in immune defence on the one hand and developmental biology on the other. A research team from Kiel University (Germany) is now reporting that toll-receptors have primarily served to identify germs and to control bacterial colonisation of organisms \u2013 typical immune defence functions. The study was now published online in the Proceedings of the National Academy of Sciences (PNAS) and has implications for human medical research."^^<http://www.w3.org/2001/XMLSchema#string>
