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)
BACKGROUND Since publication in 2000 of the Second International Consensus Report on Diagnosis and Classification of Epidermolysis Bullosa, many advances have been made to our understanding of this group of diseases, both clinically and molecularly. At the same time, new epidermolysis bullosa (EB) subtypes have been described and similarities with some(More)
BACKGROUND Several new targeted genes and clinical subtypes have been identified since publication in 2008 of the report of the last international consensus meeting on diagnosis and classification of epidermolysis bullosa (EB). As a correlate, new clinical manifestations have been seen in several subtypes previously described. OBJECTIVE We sought to(More)
In response to extracellular signals, cell surface receptors engage in connections with multiple intracellular signaling pathways, leading to the cellular responses such as survival, migration, proliferation and differentiation. The 'pY-->SH2/SH3-->effector' connection is a frequently used scheme by many cell surface receptors, in which SH2/SH3-containing(More)
A genome-wide screen revealed previously unidentified components required for transport and Golgi organization (TANGO). We now provide evidence that one of these proteins, TANGO1, is an integral membrane protein localized to endoplasmic reticulum (ER) exit sites, with a luminal SH3 domain and a cytoplasmic proline-rich domain (PRD). Knockdown of TANGO1(More)
Epidermolysis bullosa acquisita (EBA) is an acquired blistering skin disease characterized by the presence of IgG autoantibodies to type VII collagen. EBA autoantibodies recognize four major immunodominant epitopes localized within the amino-terminal, noncollagenous (NC1) domain. In this study, we developed a rapid, quantitative enzyme-linked immunosorbent(More)
Treatment of epidermolysis bullosa acquisita (EBA) with conventional therapy frequently does not result in improvement. Extracorporeal photochemotherapy (ECP) is a novel immunomodulating technique which might be of benefit in the treatment of autoimmune disease. We prospectively studied three patients with refractory EBA who were treated with ECP. All three(More)
Epidermolysis bullosa acquisita (EBA) is a severe, chronic blistering disease of the skin. EBA patients have circulating and tissue-bound autoantibodies to a large (Mr = 290,000) macromolecule that is localized within the basement membrane zone between the epidermis and dermis of skin, the site of blister formation. The "EBA antigen" is known to be distinct(More)
Type VII collagen, a major component of skin-anchoring fibrils, is synthesized by both fibroblasts and keratinocytes, the two principal cell types in the skin. In this study, we examined the effects of ultraviolet A (UVA) irradiation on the expression of type VII collagen in human fibroblasts. UVA irradiation (0-15 J/cm2) caused a dose-dependent increase(More)
Type VII collagen is synthesized and secreted by both human keratinocytes and fibroblasts. Although both cell types can secrete type VII collagen, it is thought that keratinocytes account for type VII collagen at the dermal-epidermal junction (DEJ). In this study, we examined if type VII collagen secreted solely by dermal fibroblasts could be transported to(More)
