alphadogg writes "This year's Nobel Laureates have revolutionized our understanding of the immune system by discovering key principles for its activation. Scientists have long been searching for the gatekeepers of the immune response by which man and other animals defend themselves against attack by bacteria and other microorganisms. Bruce Beutler and Jules Hoffmann discovered receptor proteins that can recognize such microorganisms and activate innate immunity, the first step in the body's immune response. Ralph Steinman discovered the dendritic cells of the immune system and their unique capacity to activate and regulate adaptive immunity, the later stage of the immune response during which microorganisms are cleared from the body."
The opposite of a correct statement is a false statement. But the opposite
of a profound truth may well be another profound truth.
