Abstract Autoantibodies to DNA were discovered over 40 years ago following the discovery a few years earlier of the 'LE' cell phenomenon by Hargraves and colleagues in 1948. These investigators noted that, when leucocytes were incubated with serum from lupus patients, changes in the nucleus could be seen together with phagocytosis of nuclear remnants by polymorphonuclear leucocytes. Since that time numerous studies in many laboratories have investigated almost every aspect of anti-DNA antibodies, partly to identify what determines their pathology. Whilst a subset of anti-DNA antibodies, especially anti-native, or double-stranded DNA (dsDNA) antibodies constitutes a hallmark of lupus disease and a diagnostic criterion, it is now clear that not all anti-DNA autoantibodies are of pathogenic relevance. Moreover, anti-DNA autoantibodies may also be found in other connective tissue disorders. Here we briefly review studies presented at the fifth international workshop on anti-DNA autoantibodies held in London to highlight relevant properties of pathogenic anti-DNA antibodies.
