Dermatitis herpetiformis sera or goat anti-transglutaminase-3 transferred to human skin-grafted mice mimics dermatitis herpetiformis immunopathology.

Dermatitis herpetiformis (DH) is characterized by deposition of IgA in the papillary dermis. However, indirect immunofluorescence is routinely negative, raising the question of the mechanism of formation of these immune deposits. Sárdy et al. (2002. J. Exp. Med. 195: 747-757) reported that transglutaminase-3 (TG3) colocalizes with the IgA. We sought to create such deposits using passive transfe...

Dermatitis herpetiformis.

Dermatitis herpetiformis (DH) is an autoimmune, pleiomorphic, papulovesicular disorder associated with celiac disease and gluten sensitivity. DH is characterized by subepidermal bullae on hematoxylin and eosin staining and granular immunoglobulin A deposits in the dermal papillae using the direct immunofluorescence method. Antibodies to tissue transglutaminase and epidermal transgulatminase can...

Dermatitis herpetiformis.

Dermatitis herpetiformis (DH), described over 100 years ago, is a life-long blistering skin disease that can appear at any age. Dapsone controls the rash effectively and has been used for over 50 years in the treatment of DH. Major landmark in the research of DH was 30 years ago the discovery of granular IgA deposits in the upper papillary dermis,1 and further differentiation of an autoimmune d...

Dermatitis herpetiformis and vitiligo.

Dermatitis herpetiformis (DH) is a rare immunobullous disorder of the skin that is associated with gluten hypersensitivity. Subepidermal IgA-type antibody deposition against tissue transglutaminase leads to dense neutrophilic microabscess and eventually into vesicles in dermal papillae, which may occasionally merge into bullae. Being a subepidermal vesiculobullous disorder, DH is frequently ass...
