Dermatitis herpetiformis (DH) and bullous pemphigoid (BP) are skin diseases associated with eosinophilic and neutrophilic infiltrations. Although cytokines are critical for the inflammatory process, there are single findings concerning concentration of IL-17 in bullous diseases. The goal of this study was to assess IL-17 expression in DH and BP patients. Skin biopsies were taken from 10 DH, 14 BP patients and from 10 healthy subjects. The localization and expression of IL-17 was studied by immunohistochemistry and the serum concentration was measured by immunoassays. Expression of IL-17 in the epidermis and in influxed cells in dermis was detected in skin biopsies. Expression of IL-17 was statistically higher in epidermis and infiltration cells in specimens from BP than from DH patients. Examined interleukin expression was detected in perilesional skin of all patients but it was much lower than in lesional skin. The expression of IL-17 was not observed in biopsies from healthy people. Serum level of IL-17 was statistically higher in BP and DH groups as compared to control group. Our results provide the evidence that IL-17 may play an essential role in activating and recruiting eosinophils and neutrophils, which ultimately contribute to the tissue damage in DH and BP.

Bullous pemphigoid (BP) and dermatitis herpetiformis (DH) are skin diseases associated with inflammation. However, few findings exist concerning the role of mast cells in autoimmune blistering disease. Skin biopsies were taken from 27 BP and 14 DH patients, as well as 20 healthy individuals. Immunohistochemistry was used to identify the localization and mast cell expression of TNFα and MMP9 in skin lesions and perilesional skin. The serum concentrations of TNFα, MMP9, chymase, tryptase, PAF, and IL-4 were measured by immunoassay. TNFα and MMP9 expression in the epidermis and in inflammatory influxed cells in the dermis was detected in skin biopsies from patients. Although these mediators were found to be expressed in the perilesional skin of all patients, the level was much lower than that in lesional skin. Increased serum PAF levels were observed in BP patients. Mast cells may play an essential role in activating inflammation, which ultimately contributes to the tissue damage observed in BP and DH. Our findings suggest that differences in the pattern of cytokine expression directly contribute to variations in cellular infiltration in DH and BP.

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 biopsies were taken from 14 patients with DH, 27 with BP, and 20 control subjects. The localization and expression of tissue factor (TF) in skin lesions and perilesional skin were studied by immunohistochemistry and confirmed by Western Blot. Moreover the plasma concentrations of TF were measured by immunoassays. D dimers, fibrinogen, and selected coagulation parameters were measured by routine methods. Expression of TF in the epidermis and in inflammatory influxed cells in dermis was detected in skin biopsies from BP patients. Examined TF expression was detected in perilesional skin of all BP patients too. The expression of TF was not observed in biopsies from healthy people and DH patients. The findings of the study show an increased expression of tissue factor in the lesional and perilesional skin of patients with bullous pemphigoid. The difference in chemokine pattern expression and variations in the cellular infiltration in BP and DH cause variable expression of TF.

The role of the process of apoptosis is investigated in the pathogenesis of many autoimmune diseases; however at present, there is not much information about its role in dermatitis herpetiformis. Skin biopsies were taken from 18 DH patients and from 10 healthy subjects. The localization and expression of Bax, Fas, FasL, TRAIL, TRAIL-R in skin lesions, and perilesional skin were studied by immunohistochemistry. Expression of Bax, Fas, and Fas ligand was detected in the keratinocytes in skin biopsies from DH patients. Expression of TRAIL and TRAIL receptor was confirmed in epidermis, infiltration cells, and some fibroblasts. The expression of examined molecules in biopsies from healthy people was observed only in single cells. There were statistically significant differences between lesional, perilesional, and healthy skin of control group in Bax expression analysis and between lesional skin and control group in Fas, FasL, and TRAIL expression. There were statistically significant differences between control group and perilesional skin in Bax and FasL expression. Our results show that selected proapoptotic molecules may take part in pathogenesis of dermatitis herpetiformis, but the role of apoptosis in this process is not clear.

Apoptosis is a form of cell death that is claimed to be involved in a number of chronic inflammatory and malignant skin diseases. The aim of this study was to investigate whether apoptosis may contribute to the pathogenesis of epidermal changes in dermatitis herpetiformis (DH) and, in particular, whether certain apoptosis-related markers such as Bax, Bcl-2, Fas and Fas ligand (FasL) take part in this process. For the detection of apoptotic nuclei, terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labelling technique (TUNEL) was employed on cryostat sections. Skin lesions from six and perilesional skin from four DH patients were stained with monoclonal antibodies to Bax, Bcl-2, Fas and FasL. The same evaluation was also performed on three patients affected by bullous pemphigoid (BP) and in two healthy donors. Using TUNEL technique, a remarkable increase in the apoptotic rate within the epidermal compartment was observed in DH and BP patients in comparison with normal controls. In our immunohistochemical analysis, Bax/Bcl-2 ratio was almost the same in the epidermis of perilesional/lesional DH, BP and healthy skin specimens. In DH and BP specimens both Bax and Bcl-2 proteins were increased in the dermal perivascular compartment. Fas showed a prevalently epidermal staining, both in DH and BP lesions, while FasL was distributed in perivascular and subjunctional dermis; some FasL+ cells infiltrated the DEJ and the basal layer of epidermis. This study allowed us to highlight conspicuous apoptotic phenomena in basal and suprabasal keratinocytes within lesional and perilesional skin of DH. We conclude that in DH, as well as in BP, apoptosis plays a role in the pathogenesis of cutaneous lesions in concert with other pathogenetic mechanisms.

Stat Signaling

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 concerning autoimmune bullous diseases yet to be published. The aim of this study was to evaluate the expression of proteins constituting the JAK/STAT signaling pathway in skin lesions and perilesional area in dermatitis herpetiformis (DH) and bullous pemphigoid (BP), as well as in the control group. Skin biopsies were collected from 21 DH patients, from 20 BP patients, and from 10 healthy volunteers. The localization and expression of selected STAT and JAK proteins were examined by immunohistochemistry and immunoblotting. We found significantly higher expression of JAK/STAT proteins in skin lesions in patients with BP and DH, in comparison to perilesional skin and the control group, which may be related to proinflammatory cytokine network and induction of inflammatory infiltrate in tissues. Our findings suggest that differences in the JAK and STAT expression may be related to distinct cytokines activating them and mediating neutrophilic and/or eosinophilic infiltrate.

Introduction. The introduction of antiretroviral therapy has significantly improved the long-term prognosis of AIDS patients, but opportunistic infections can still be life-threatening for this population. Among them, a large group constitutes of herpesvirus infections, which are frequent manifest forms of dermatological manifestations of HIV. The researching of IL-31, as a prospective diagnostic predictor of dermatological diseases, has been actively conducted in recent years. This is due to the interest in its biological action, which extends primarily to the skin. Тhe identification of molecular targets underlying inflammatory and infectious dermatoses is promisingly for the development of new, targeted treatments. Objective: to study the role of IL-31 in the immunopathogenesis of herpesvirus infections associated with HIV infection. Research objectives: 1) to compare the levels of IL-31 in the blood serum in patients with herpesvirus skin diseases associated with HIV infection and in healthy subjects; 2) to determine the presence of a relationship between the levels of IL-31 in the blood serum and the clinical stage of the disease. Materials and methods. The study included patients with herpesvirus infection caused by HSV-1, HSV-2, VZV-3, EBV and HHV-8 associated with HIV infection and healthy individuals. Serum IL-31 levels were measured by ELISA using commercial kits (Human IL-31 ELISA Kit, Abcam, Cambridge, MA, USA). Were collected the baseline clinical characteristics, assessment of the activity of the infectious process and the degree of immunosuppression. Results. Our study involved 39 patients with herpesvirus infection associated HIV and 31 patients of the control group. In patients with herpesvirus infection against the background of HIV infection, the average level of IL-31 in the blood serum was significantly higher than that of healthy subjects. Serum IL-31 levels in patients with herpesvirus infection did not differ significantly depending on the severity of the process and the degree of immunosuppression. Conclusion. The levels of IL-31 in the blood serum of patients with herpesvirus infection were differed by statistically significant validity in comparison with similar indicators of healthy individuals, which confirms its role in the pathogenesis of infectious skin diseases.

Blister development in bullous pemphigoid (BP) results from destruction of hemidesmosomes and basement membrane components within the dermoepidermal junction by autoantibodies. Adhesion molecules can take part in pathogenesis of this disease. The aim of the study was to determine the localization and expression of L- and E-selectins andβ1,β3, andβ4 integrins by immunohistochemistry in skin lesions of 21 patients with BP, compared with 10 healthy subjects. Expression of L and E selectins andβ1,β3 integrins was detected mainly in basal keratinocytes and in inflammatory infiltrates in the dermis, expression ofβ4 integrin was irregular and was detected mainly in dermal part of the blister, while in the control group only weak and single expression of the examined molecules was detected in basal keratinocytes and endothelium cells. The obtained results reveal the important role of selected selectins and integrins in development of skin lesions in BP.

Dermatitis herpetiformis (DH) is a subepidermal autoimmune disease characterized by skin and intestinal lesions consistent with coeliac disease. There are also some data that metalloproteinases (MMPs) are involved in the development of skin lesions in DH, however their exact role in this process is not fully understood. The aim of the study was to investigate whether MMPs and their inhibitors are involved in pathogenesis of DH. Skin biopsies were taken from 13 patients with active DH and from 10 healthy subjects. The localization and expression of MMPs and TIMPs were examined by immunohistochemistry. MMPs expression was detected in basal keratinocytes and in the whole epidermis in all of the DH subjects. Neutrophils in microabscesses and in blister fluid were also positive for MMPs. Expression of TIMPs was moderate or weak in all examined biopsies. Our results allow us to conclude that imbalance between these enzymes takes an important role in the pathogenesis of DH.

Subepidermal blistering diseases of childhood have, in the past, been thought to represent cases of juvenile dermatitis herpetiformis, bullous pemphigoid, or benign chronic bullous dermatosis of childhood. While the small-blister variety closely resembles adult-type dermatitis herpetiformis, the large-blister, or bullous, variety has clinical and histologic resemblances to bullous pemphigoid. The patient presented in this report clearly fits previous descriptions of the large-blister type of juvenile dermatitis herpetiformis, bullous pemphigoid, or benign chronic bullous dermatosis of childhood both clinically and histologically, while his therapeutic response to dapsone and the presence of in vivo bound IgA at the basement membrane of normal and perilesional skin are highly characteristic of the adult type of dermatitis herpetiformis. Immunofluorescent studies of similar cases reported in the literature, however, have shown variable results, thus obscuring their classification. Though the proper place of all such cases in the nosology of blistering diseases is not yet clear, at least some of them closely resemble adult-type dermatitis herpetiformis by two important criteria-immunologic and therapeutic.
