Abstract

Pemphigus is a group of rare autoimmune blistering diseases of the skin in which autoantibodies to desmosome cadherins, desmogleins, induce loss of cell-cell adhesion (acantholysis). In addition to steric hindrance and activation of intracellular phosphorylation cascade signaling pathways, apoptosis has been suggested to contribute to the mechanism by which pathogenic IgG induces acantholysis. We review the literature examining the role of apoptosis in pemphigus. Current data recognize a central role of apoptosis in the mechanisms of blister induction. In particular, here we stress the key role of FasL in pemphigus, as it is able to first induce apoptosis, then acantholysis. Being pro-apoptotic molecules important in blister formation, they could represent new specific targets for pemphigus treatment.
