Volume 2 Issue 9, September 2001

Red plaster mask representing the twisting of the immune system, normally a protector of health and well being (right side of mask) into an instrument of destruction and dysregulation (left side). Half of this month's issue (pages 755 to 822) is focused on the new theoretical frameworks that have arisen to explain autoimmunity and recent developments in treatment of autoimmune disorders. Additional features are available free on Nature Immunology's website (immunol.nature.com). Mask by Christopher Cassidy.

  • Type 1 diabetes is preventable in animal models and predictable in humans. The increase in our knowledge of basic immunology has allowed the initiation of large-scale clinical efforts to prevent diabetes.

  • Graves' disease and other autoimmune syndromes affecting the thyroid are the archetypes of organ-specific autoimmunity. Despite intensive research, the relative contribution of genetic and environmental factors to disease pathogenesis is not clear. Here, the latest developments in understanding the determinants of these diseases are discussed.

  • Autoimmune diseases are more prevalent in women than men. A new interest in understanding the biology of this difference as well as funding opportunities have focused attention on research priorities in sex differences.

  • Differences in multiple sclerosis patient's disease and their responses to standard drugs indicate that today's therapies need to be more individualized. It is proposed that gene expression profiling in conjunction with magnetic resonance imaging be used to optimize future treatment approaches.

  • In early July 2001 a small meeting was held in Baltimore on the associations of lymphomas with autoimmune conditions. Topics ranged from the effects of defective apoptosis to questions of antigen-drive lymphoproliferation.

  • Individual lymphocytes express antigen receptors of a singular specificity. How this process, known as allelic exclusion, is established and maintained is unknown. Differences in subnuclear localization appear to contribute to enforcement of monoallelic receptor expression.

  • The era of genomic-wide sequence analysis promises to yield new insights in global regulatory gene control. Comparative genome studies have identified a critical regulator of TH2 cytokine expression.

  • Although some cellular responses induced by TLRs are abolished in MyD88-deficient mice, TLR4, unlike TLR9, can still induce activation of NF-κB and MAPKs. The discovery of a cytoplasmic adapter protein for TLR4, called TIRAP, helps explain this phenomenon.

  • Dendritic cells can prime naïve lymphocytes. New data show how dendritic cells provide early activation cues by expression of IL-2, which may greatly enhance both T and B cell responses.
