Pemphigus is caused by loss of epidermal cells cohesion and detachment of keratinocytes, termed acantholysis [1]. Pemphigus exists in two major types, pemphigus vulgaris (PV) which is a clinically severe form of the disease affecting both the skin and mucosal membranes with stratified epithelium (oral mucosa, oesophagus, genital mucosa) and pemphigus foliaceus (PF) with a milder clinical picture where acantholysis is found in the skin alone. The major clinical variant, pemphigus vulgaris (PV) is caused by a loss of intercellular adhesion of epidermal keratinocytes which is induced by IgG autoantibodies against components of desmosomes.

An introduction to the immune pathogenesis of pemphigus vulgaris Pemphigus vulgaris (PV) is a life‐threatening autoimmune blistering disease caused by anti‐desmoglein (Dsg) IgG that leads to a loss of epidermal cell-cell adhesion, called acantholysis, leading to chronic, progressive blistering of the mucous membranes and skin. In these disorders, autoantibodies are mainly directed to desmosomal cadherins. Though the pathogenetic role of autoantibodies directed against desmoglein 3 is certain, a number of other factors have been suggested to determine acantholysis in PV.

Pemphigus vulgaris (PV) is the most common subtype, and is characterized by . Altered microRNA expression is found in serum, cells and tissues of pemphigus and pemphigoid patients. Pemphigus Vulgaris is an autoimmune disease that results in blister formation in the epidermis and in mucosal tissues due to antibodies recognizing desmosomal cadherins, mainly desmoglein-3 and -1. In PV, antibodies against desmoglein 3 (Dsg3) cause loss of cell adhesion in the deep layers of stratified squamous epithelia, whereas in PF, anti-desmoglein 1 (Dsg1) antibodies cause loss of cell adhesion in superficial epidermis but not in mucous membrane. Pemphigus vegetans - rare variant of Vulgaris - split into Hallopeau (mild) and Nenmann (severe) - forms vegetations and papillomatous proliferations!! predominant apoptotic pathway involved in the pathogenesis of pemphigus vulgaris is the extrinsic pathway (86% of the reviewed studies). The oral lesions are usually painful erosions and ulcers. N Engl J Med 2007;357:545-52. Despite numerous investigations, the pathological mechanisms of PV are still incompletely understood .
