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 Hoffman have contributed to our understanding of how so-called receptors detect microorganisms and activate our innate immunity. In 1998, by studying mice with mutations, Bruce Beutler found a gene which is active in the development of a receptor which binds lipopolysaccharide, a substance produced by several pathogenic bacteria.
