Pemphigus vulgaris acantholysis ameliorated by cholinergic agonists.
BACKGROUND Pemphigus vulgaris (PV) is an autoimmune, IgG autoantibody-mediated disease of skin and mucosa leading to progressive blistering and nonhealing erosions. Patients develop autoantibodies to adhesion molecules mediating intercellular adhesion and to keratinocyte cholinergic receptors regulating cell adhesion. OBSERVATIONS To determine whether a cholinergic agonist can abolish PV IgG-...
متن کاملScanning electron microscopy of acantholysis in pemphigus foliaceus*
We performed scanning electron microscopy of an inverted blister roof in a case of pemphigus foliaceus. The loss of intercellular adherence could be easily seen with low magnification. The acantholytic keratinocytes displayed an irregular and sometimes polygonal contour. Round cells, typically seen in light microscopy, were also observed. The examination of a blister roof allows ultrastructural...
متن کاملApoptosis is not required for acantholysis in pemphigus vulgaris.
The autoimmune blistering skin disease pemphigus vulgaris (PV) is caused primarily by autoantibodies against desmosomal cadherins. It was reported that apoptosis can be detected in pemphigus skin lesions and that apoptosis can be induced by PV-IgG in cultured keratinocytes. However, the role of apoptosis in PV pathogenesis is unclear at present. In this study, we provide evidence that apoptosis...
متن کاملA unique case of localized pemphigus vulgaris.
A 47-year-old Japanese male noticed an erosive lesion on his left lower lip margin in February 1995. Treatment with a corticosteroid ointment gave no improvement. In March 1995, he also noticed a keratotic lesion on his left shoulder; the keratotic mass sometimes fell off, resulting in an erosive lesion, which then became keratotic again. Prior to the lesions, no bulla had been formed. When exa...
متن کاملA Hypothesis Concerning a Potential Involvement of Ceramide in Apoptosis and Acantholysis Induced by Pemphigus Autoantibodies
Autoimmune diseases affect more than 50 million Americans, resulting in significant healthcare costs. Most autoimmune diseases occur sporadically; however, endemic pemphigus foliaceus (EPF) is an autoimmune skin disease localized to specific geographic loci. EPF, and the related diseases pemphigus vulgaris (PV) and pemphigus foliaceus (PF), are characterized by skin lesions and autoantibodies t...
