bullous impetigo
Sunday 5 February 2006
Desmosomal cadherins are the pathophysiologic targets of autoimmune or toxin-mediated disruption in the human diseases pemphigus and bullous impetigo, including its generalized form, called staphylococcal scalded skin syndrome (SSSS).
Conformational epitopes of antidesmoglein autoantibodies in pemphigus patients sera and the specific cleavage site of desmoglein-1 (DSG1) by exfoliative toxin have been identified, implicating the N-terminal extracellular domains of the desmogleins as critical regions for controlling intercellular adhesion.
