Abstract

Pemphigus vulgaris is an autoimmune blistering disease caused by anti-desmoglein 3 IgG autoantibodies. It is accepted that interactions between autoreactive B and T cells are key to humoral autoimmunity targeting desmoglein 3. This orchestrated process usually occurs in secondary lymphoid organs, including the spleen and lymph nodes. Thus, it seems likely that autoreactive B cells reside and produce autoantibodies in these tissues. Yuan et al. analyzed lymphocytes in the lesional skin of patients with pemphigus vulgaris using several experimental techniques and concluded that desmoglein 3-reactive B cells were present. This finding expands our understanding of the pathogenesis of pemphigus and should be considered when following the clinical course of skin lesions and thinking about adjunctive therapy.
