OBJECTIVE We aimed to develop consensus-based recommendations for streamlining medical communication among various health care professionals, to improve accuracy of diagnosis and treatment, and to facilitate future investigations for mucous membrane pemphigoid. PARTICIPANTS Because of the highly specific nature of this group of diseases, the 26 invited(More)
In most stem cell systems, the organization of the stem cell niche and the anchoring matrix required for stem cell maintenance are largely unknown. We report here that collagen XVII (COL17A1/BP180/BPAG2), a hemidesmosomal transmembrane collagen, is highly expressed in hair follicle stem cells (HFSCs) and is required for the maintenance not only of HFSCs but(More)
Transmissibility of characteristic lesions to experimental animals may help us understand the pathomechanism of human autoimmune disease. Here we show that human autoimmune disease can be reproduced using genetically engineered model mice. Bullous pemphigoid (BP) is the most common serious autoimmune blistering skin disease, with a considerable body of(More)
Junctional EB was once considered a uniformly fetal autosomal recessive skin disease. One of the first and best characterized forms of generalized JEB that has a more favorable prognosis was GABEB. Since its initial description in 1976, many additional cases have been compiled, all sharing the features of chronic blistering from birth, nail dystrophy, hair(More)
Antibodies against the extracellular domain of bullous pemphigoid antigen 2 (BPAG2) are thought to play a key role in the pathogenesis of bullous pemphigoid (BP), the most frequent autoimmune bullous disease of the skin. Autoreactive T cell responses to BPAG2 were investigated in 16 BP patients and 24 healthy controls by coculture of PBMC with two(More)
We have examined the release of histamine and LTC4 from purified human basophils challenged with several different stimuli, both physiological and nonphysiological. Basophils (n = 16) challenged with 0.1 micrograms/ml anti-IgE released 38 +/- 4% of their available histamine and 39 +/- 12 ng LTC4/10(6) basophils within 15-30 min. F-Met peptide (n = 8) caused(More)
CD200 (OX-2) is a transmembrane glycoprotein that transmits an immunoregulatory signal through the CD200 receptor (CD200R) to attenuate inflammatory reactions and promote immune tolerance. CD200 expression in the skin has not been described previously. We now report that freshly isolated cells of the murine epidermis contain a subpopulation of major(More)
Non-Herlitz junctional epidermolysis bullosa (nH JEB) is characterized by generalized blisters that predominate in sites exposed to friction, trauma, or heat. Whereas infants and children with nH JEB often appear to resemble patients with other forms of EB, adults with this disorder typically display atrophic scars, hypopigmentation, or hyperpigmentation at(More)
Although bullous pemphigoid and cicatricial pemphigoid are sometimes associated with malignancy, it remains uncertain whether such an association is pathogenetically related or just a coincidence attributable to the advanced age of the patients. We report a 61-year-old patient with antiepiligrin (laminin 5) cicatricial pemphigoid (AeCP) associated with an(More)
Autoimmune blistering diseases are generally distinct entities characterized by relatively consistent clinical, histologic, and immunopathologic findings. These disorders may cause impaired adhesion of epidermis to epidermal basement membrane (eg, the pemphigoid group of disorders [bullous, gestational, and mucous membrane]) or impaired adhesion of(More)
