ReviewAutoimmune bullous skin diseases, pemphigus and pemphigoid.
Autoimmune bullous skin diseases, such as pemphigus and pemphigoid, may enable clarification of the mechanisms of immune regulation in the skin. Pemphigus and pemphigoid are mediated by essentially IgG autoantibodies against structural proteins of the desmosomes at cell-cell junctions and hemidesmosomes at epidermal-dermal junctions, respectively, and are characterized by blisters and erosions in the skin and/or mucous membranes. Intensive investigation over the last 3 decades has identified their target antigens and developed serological diagnostic tools as well as mouse models to help us understand their pathophysiology. Based on these advances, several new therapeutic approaches have become available, and more effective and less toxic targeted approaches are under development.

On the cause and consequences of IgE to galactose-α-1,3-galactose: A report from the National Institute of Allergy and Infectious Diseases Workshop on Understanding IgE-Mediated Mammalian Meat Allergy.
The mammalian meat allergy known as the "α-Gal syndrome" relates to IgE specific for galactose-α-1,3-galactose (α-Gal), an oligosaccharide that is present in cells and tissues of nonprimate mammals. The recognition of delayed reactions to food derived from mammals in patients with IgE to α-Gal and also the association with tick bites have been increasing worldwide. ⋯ The participants provided suggestions for specific research priorities and for the development of resources to advance our knowledge of the mechanisms, diagnosis, management, and prevention of this allergic disease. This publication is a summary of the workshop and the panel's recommendations are presented herein.
