Molecular Autoimmunity

2004 marks the 100th anniversary of the first description of the autoimmune disease paroxysmal cold hemoglobinuria, a rare hemolytic disorder, by Julius Donath and Karl Landsteiner. After a century of research, the list of autoimmune diseases has become impressive. With a prevalence of approximately 5% of the world-wide population, these chronic, debilitating conditions affect almost every major organ of the body and, for reasons that remain unclear, are much more prevalent in woman than in men.
