    Pemphigus.
    Nat Rev Dis Primers 2017 May 11;3:17026. Epub 2017 May 11.
    Department of Dermatology, Keio University School of Medicine, 35 Shinanomachi, Shinjuku-ku, Tokyo 160-8582, Japan.
    Pemphigus is a group of IgG-mediated autoimmune diseases of stratified squamous epithelia, such as the skin and oral mucosa, in which acantholysis (the loss of cell adhesion) causes blisters and erosions. Pemphigus has three major subtypes: pemphigus vulgaris, pemphigus foliaceus and paraneoplastic pemphigus. IgG autoantibodies are characteristically raised against desmoglein 1 and desmoglein 3, which are cell-cell adhesion molecules found in desmosomes. Read More

    Childhood Pemphigus Foliaceus with Exclusive Immunoglobulin G Autoantibodies to Desmocollins.
    Pediatr Dermatol 2016 Jan-Feb;33(1):e10-3
    Department of Dermatology, Tel Aviv Sourasky Medical Center, Tel Aviv, Israel.
    Pemphigus refers to a group of potentially fatal blistering skin diseases that are often due to the deleterious effects of autoantibodies directed against desmosomal antigens. Although desmogleins have been mainly implicated as autoantigens in pemphigus, a steadily growing body of evidence suggests that other desmosomal proteins may be causally involved as well. Antibodies directed against desmocollin-3 have been shown to play a direct role in the pathogenesis of several types of pemphigus. Read More
