Cím:Repopulation of Langerhans cells during wound healing in an experimental human skin/SCID mouse model / Juhász István, Simon Miklós, Herlyn Meenhard, Hunyadi János
Dátum:1996
ISSN:0165-2478
Megjegyzések:The epidermal repopulation of Langerhans cells (LCs) during wound healing was examined using a human skin severe combined immunodeficient (SCID) mouse model. The experiments, were carried out after proving the human origin of keratinocytes repopulating the wound beds using the W6/32 monoclonal antibody. It was shown that CD1a- and HLA-DR-positive dendritic cells (mostly LCs) are already detectable 2 days after injury within the newly formed epithelium. In the excisional wounds investigated, neither HLA-DR nor ICAM-1 expression of human keratinocytes was observed. Our present data suggest that LC repopulation is an early event in the process of re-epithelization.

Cím:Myeloid but not plasmacytoid blood DCs possess Th1 polarizing and Th1/Th17 recruiting capacity in psoriasis / Khasawneh Ahmad, Baráth Sándor, Medgyesi Barbara, Béke Gabriella, Dajnoki Zsolt, Gáspár Krisztián, Jenei Adrienn, Pogácsás Lilla, Pázmándi Kitti, Gaál János, Bácsi Attila, Szegedi Andrea, Kapitány Anikó

Megjegyzések:Psoriasis is a common inflammatory skin disease and dendritic cells (DCs) play crucial role in the development of skin inflammation. Although the characteristics of skin DCs in psoriasis are well defined, less is known about their peripheral blood precursors. Our aim was to characterize the phenotypic features as well as the cytokine and chemokine production of CD1c+ myeloid DCs (mDCs) and plasmacytoid DCs (pDCs) in the blood samples of psoriatic patients. Blood DCs were isolated by using a magnetic separation kit, and their intracytoplasmic cytokine production and CD83/CD86 maturation/activation marker expression were investigated by 8-colour flow cytometry. In CD1c+ mDCs the intracellular productions of Th1, Th2, Th17, Th22 and Treg polarizing cytokines were examined simultaneously, whereas in pDCs the amounts of IFN? as well as IL-12, IL-23 and IL-6 were investigated. The chemokine production of both DC populations was investigated by flow-cytometry and ELISA. According to our results psoriatic CD1c+ mDCs were in a premature state since their CD83/CD86 maturation/activation marker expression, IL-12 cytokine, CXCL9 and CCL20 chemokine production was significantly higher compared to control cells. On the other hand, blood pDCs neither produced any of the investigated cytokines and chemokines nor expressed CD83/CD86 maturation/activation markers. Our results indicate that in psoriasis not only skin but also blood mDCs perform Th1 polarizing and Th1/Th17 recruiting capacity, while pDCs function only in the skin milieu.

Cím:Expansion of circulating follicular T helper cells associates with disease severity in childhood atopic dermatitis / Szabó Krisztina, Gáspár Krisztián, Dajnoki Zsolt, Papp Gábor, Fábos Beáta, Szegedi Andrea, Zeher Margit
Dátum:2017

Megjegyzések:Follicular helper T (TFH) cells play crucial role in B-cell differentiation and antibody production. Although, atopic dermatitis (AD) is often associated with increased serum IgE levels, B-cell mediated responses have not been studied thoroughly. The aim of our study was to investigate the proportion of TFH-like cells in the disease. Twelve children and 17 adults with AD as well as 14 healthy controls were enrolled in the study. The frequency of CD4+CXCR5+ICOS+PD-1+ TFH-like cells and their IL-21 cytokine production were determined by flow cytometry. Immunohistochemical analysis was performed on skin biopsy specimens from AD patients for the detection of TFH markers. The percentages and absolute numbers of circulating TFH-like cells were significantly increased in children with AD compared to adult patients and healthy controls. IL-21 cytokine production of TFH-like cells was also elevated and showed a strong positive correlation with paediatric patients' SCORAD index. The expression of TFH-specific markers showed only a non-specific scattered pattern in skin biopsy specimens. This is the first study to demonstrate that TFH-like cells expanded in the peripheral blood of children with AD compared to adults. These results reinforce the importance of further investigations on TFH-like cells in different phenotypes and endotypes of AD.

Cím:Elevated rate of Thelper1 (T(H)1) lymphocytes and serum IFN-gamma levels in psoriatic patients / Andrea Szegedi, Magdolna Aleksza, Andrea Gonda, Beatrix Irinyi, Sándor Sipka, János Hunyadi, Péter Antal-Szalmás
Dátum:2003
ISSN:0165-2478
Megjegyzések:Several disorders are known to be associated with altered Thelper1/Thelper2 (T(H)1/T(H)2) cytokine balance. Psoriasis is characterized by increased systemic and local production of T(H)1 and pro-inflammatory cytokines. Furthermore recent data indicate the dominant presence of T(H)1 lymphocytes in the circulation and T(H)1 and Tcytotoxic1 (T(C)1) cells in lesional skin of psoriatic patients. In order to assess the systemic T(H)1/T(H)2 imbalance in psoriasis most of the studies so far tested isolated peripheral mononuclear cells. As a new approach we applied a whole blood flow cytometric assay to determine the rate of circulating T(H)1/T(H)2 and T(C)1/Tcytotoxic2 (T(C)2) lymphocytes based on their intracellular IFN-gamma, IL-4 and IL-10 expression. Besides, serum levels of these cytokines were determined in healthy controls and psoriatic patients by commercial ELISAs. In psoriatic patients we found significantly (P<0.02) increased rates of CD4(+)/IFN-gamma(+) lymphocytes (30.3+/-8.8%) while the percent of CD4(+)/IL-4(+) cells (0.37+/-0.31%) were significantly (P<0.03) lower compared to healthy controls (CD4(+)/IFN-gamma(+): 20.1+/-7.3% and CD4(+)/IL-4(+): 0.78+/-0.44%). The IL-10-positive CD4(+) and CD8(+) cells also had higher rate in psoriasis, but the difference between patients and controls was not significant, similarly to the rate of CD8(+)/IFN-gamma(+) and CD8(+)/IL-4(+) lymphocytes. Beside cellular expression, serum IFN-gamma levels were also significantly higher (control: 4.9+/-6.4 pg/ml; psoriatic patients: 35.9+/-47.0 pg/ml; P<0.05). Our results provide further evidence for an altered T(H)1/T(H)2 balance in psoriasis measured in non-separated whole blood T cells.
