Inmunopatogenia del pénfigo vulgar y el pénfigo foliáceo
ABSTRACT: Pemphigus vulgaris and pemphigus foliaceus are autoimmune blistering diseases mediated by antibodies against desmosomal proteins. They are strongly associated with major histocompatibility complex alleles with the ability to present antigenic peptides of desmogleins. In the affected indivi...

| Summary: | ABSTRACT: Pemphigus vulgaris and pemphigus foliaceus are autoimmune blistering diseases mediated by antibodies against desmosomal proteins. They are strongly associated with major histocompatibility complex alleles with the ability to present antigenic peptides of desmogleins. In the affected individuals the presence of auto-reactive T and B lymphocytes, and alterations in the immune system regulation with imbalance of the Th1/Th2 responses have been described. Damage mechanisms are not yet precisely known but current investigation indicates that antibodies play an important pathogenic role: they start different signaling cascades that lead to acantholysis and apoptosis of keratinocytes. Better knowledge of the pathogenesis of autoimmune blistering diseases has been the basis for the development and implementation of new therapeutic approaches. |
