When bacteria, viruses and other microorganisms attack our bodies, our immune system goes to work. It has two lines of defence, the innate immunity and the adaptive immunity. Bruce Beutler and Jules Hoffmann have contributed to our understanding of how so-called receptors detect microorganisms and activate our innate immunity. In 1996, by studying fruit flies with mutations, Hoffmann showed that the so-called Toll-gene is active in the development of receptors which are crucial for the immune system of the fly.
