091 Gene expression profiling points to complement activation as important for blister formation in bullous pemphigoid

The complement system in bullous pemphigoid. I. Complement and component levels in sera and blister fluids.

Compared with other serum and blister fluid proteins, total hemolytic complement was reduced in the blister fluid of six serologically positive bullous pemphigold patients while four serologically negative cases had blister fluid complement levels closely approaching the serum levels. Except for pemphigus vulgaris blisters. blister fluids from most patients with other bullous diseases and exper...

92-kD gelatinase is produced by eosinophils at the site of blister formation in bullous pemphigoid and cleaves the extracellular domain of recombinant 180-kD bullous pemphigoid autoantigen.

Eosinophils are prominent in bullous pemphigoid (BP), and proteases secreted from these and other inflammatory cells may induce disruption of the basement membrane. We used in situ hybridization and immunohistochemistry to localize the sites of 92-kD gelatinase expression in BP lesions. In all samples (20/20), a strong signal for gelatinase mRNA was detected only in eosinophils and was most pro...

Bullous pemphigoid with prominent milium formation.

Milia are very common superficial keratinous cysts, clinically seen as pearly white dome-shaped lesions with a diameter of 1-2 mm. Bullous pemphigoid (BP) is an autoimmune bullous disease characterized clinically by tense bullae on the extremities and trunk. The major target autoantigens of BP are BP180 and BP230. We report a 55-year-old Polish BP patient presenting prominent milium formation. ...

Bullous pemphigoid

Disease summary: Bullous Pemphigoid is an acquired, chronic, blistering autoimmune subepidermal bullous disease in which autoantibodies are directed against component of basement membrane zone of the skin [1]. It is characterized by formation of cutaneous bullae on the skin and mucous membrane. The pathogenesis involves migration of inflammatory cells into subepithilial tissues due to activatio...
