چکیده
Bullous pemphigoid (BP) and dermatitis herpetiformis (DH) are chronic subepidermal bullous diseases, which progress together with an itch and an inflammatory reaction. These symptoms may be the cause of a phenomenon described in the literature as a neurogenic skin inflammation. Neuropeptides are one of the mediators which take part in this process. The aim of our study was to indicate the expression of selected neuropeptides - CRF (corticotropin releasing factor), CGRP (calcitonin gene-related peptide), NKB (neurokinin B), SP (substance P) and the receptor for endothelin B (ETRB) - in the skin of patients suffering from BP or DH. A significantly increased expression of CRF was found in the specimen collected from the skin lesions of patients with BP and DH as well as a significantly increased expression of receptor for endothelin B in the patients with DH by the immunohistochemical method. The results obtained give evidence of a possible participation of CRF and receptor for endothelin B in the pathogenesis of the itch in the dermatitis herpetiformis as well as CRF in bullous pemphigoid.

Expression of selected adhesion molecules in dermatitis herpetiformis and bullous pemphigoid.
Dermatitis herpetiformis (DH) and bullous pemphigoid (BP) are autoimmune diseases characterized by destruction of the basement membrane zone (BMZ) and anchoring fibres by autoantibodies and infiltration. Adhesion molecules can take part in these phenomena. Skin biopsies were taken from 13 patients with DH, 21 with BP, and from 10 healthy subjects. The localization and expression of E and L sele...
متن کاملExpression of the JAK/STAT Signaling Pathway in Bullous Pemphigoid and Dermatitis Herpetiformis
A family of eleven proteins comprises the Janus kinases (JAK) and signal transducers and activators of transcription (STAT) signaling pathway, which enables transduction of signal from cytokine receptor to the nucleus and activation of transcription of target genes. Irregular functioning of the cascade may contribute to pathogenesis of autoimmune diseases; however, there are no reports concerni...
متن کاملGenetic polymorphisms of CYP2D6 oxidation in patients with autoimmune bullous diseases
INTRODUCTION Bullous skin diseases, which include, among others pemphigoid, pemphigus, and dermatitis herpetiformis are classified as severe autoimmune dermatoses. It has been shown that a pattern of xenobiotic metabolism may play a role in the pathogenesis of autoimmune diseases. AIM To estimate whether the CYP2D6 genotype may be considered a predisposing factor in autoimmune bullous disease...
متن کاملTissue 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...

Itch which is one of the major, subjective symptoms in a course of bullous pemphigoid and dermatitis herpetiformis makes those two diseases totally different than other autoimmune blistering diseases. Its pathogenesis is still not fully known. The aim of this research was to assess the role of IL-31 in development of itch as well as to measure its intensity. Obtained results, as well as literat...
