The goal of contemporary research in pemphigus vulgaris and pemphigus foliaceus is to achieve and maintain clinical remission without corticosteroids. Recent advances of knowledge on pemphigus autoimmunity scrutinize old dogmas, resolve controversies, and open novel perspectives for treatment. Elucidation of intimate mechanisms of keratinocyte detachment and death in pemphigus has challenged th...

BACKGROUND Pemphigus is a severe autoimmune blistering disorder caused by autoantibodies to desmoglein 1 and 3. The disease course is typically severe, thus requiring multiple immunosuppressive agents. The treatment is still challenging and in some patients with recalcitrant disease, therapies fail and therapeutic options are limited. OBJECTIVES To investigate whether depletion of B lymphocyt...

Pemphigus vulgaris (PV) is an autoimmune blistering disease, in which autoantibodies against PV antigen (PVA or Dsg3) play a pathogenic role in inducing blister formation. Bacterial fusion proteins of PVA failed to absorb pathogenic autoantibodies from PV patients' sera probably because they did not represent the proper conformation. Therefore, a chimeric protein, PVIg, consisting of the whole ...

Autoantibodies against the epidermal desmosomal cadherins desmoglein 1 (Dsg1) and Dsg3 have been shown to cause severe to lethal skin blistering clinically defined as pemphigus foliaceus (PF) and pemphigus vulgaris (PV). It is unknown whether antibody-induced dissociation of keratinocytes is caused by direct inhibition of Dsg1 transinteraction or by secondary cellular responses. Here we show in...

Autoimmune skin disease occurs in pregnancy, and treatment is often required to control both maternal disease and fetal outcomes. Here we present the available safety data in pregnancy and lactation for medications used to treat autoimmune skin diseases, including cutaneous lupus erythematosus, dermatomyositis, morphea and systemic sclerosis, pemphigus vulgaris, pemphigus foliaceus, and pemphig...
