Eosinophils Mediate Tissue Injury in the Autoimmune Skin Disease Bullous Pemphigoid

The Autoimmune Skin Disease Bullous Pemphigoid: The Role of Mast Cells in Autoantibody-Induced Tissue Injury

Bullous pemphigoid (BP) is an autoimmune and inflammatory skin disease associated with subepidermal blistering and autoantibodies directed against the hemidesmosomal components BP180 and BP230. Animal models of BP were developed by passively transferring anti-BP180 IgG into mice, which recapitulates the key features of human BP. By using these in vivo model systems, key cellular and molecular e...

Low-dose oral methotrexate induces apoptosis of tissue eosinophils in bullous pemphigoid.

We have shown previously that eosinophils are abundant in blood and tissue in bullous pemphigoid and that they rapidly disappear, without sign of necrosis, during methotrexate therapy. The aim of the present study was to investigate the role of apoptosis in this phenomenon. The terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labelling method for detecting apoptosis was used,...

Differential roles for beta2 integrins in experimental autoimmune bullous pemphigoid.

Bullous pemphigoid (BP) is an autoimmune disease associated with autoantibodies directed against the hemidesmosomal antigens anti-BP230 and anti-B180. Neonatal mice injected with rabbit anti-mouse BP180 (mBP10) IgG develop a BP-like disease. Complement, immune complexes, mast cells, and neutrophils play a key role in subepidermal blistering in this animal model. In this study we investigated th...

Tissue Factor in Dermatitis Herpetiformis and Bullous Pemphigoid: Link between Immune and Coagulation System in Subepidermal Autoimmune Bullous Diseases

Dermatitis herpetiformis (DH) and bullous pemphigoid (BP) are skin diseases associated with eosinophilic and neutrophilic infiltrations. Although chemokines are critical for the selective accumulation and activation of various leukocyte subsets in the inflammatory process, there are few findings concerning inflammatory cells and production of coagulation factors in blistering diseases. Skin bio...
