What are Desmoglein antibodies?

Desmogleins are protein substances located in and on the surface of keratinocytes. These proteins have been shown to be a critical factor in cell-to-cell adhesion. Antibodies to desmogleins can result in loss of cell adhesion, the primary cause of blister formation in pemphigus.

What is the pathogenesis of pemphigus vulgaris?

The pathogenesis of pemphigus involves the production of activated B-cells and IgG with stimulation by IL-4 by T-helper 2 cells. Clinically these diseases present most often with epidermal erosions of the mucosae and skin caused by rapid rupturing of flaccid bullae.
