Cím:Colostrinin decreases hypersensitivity and allergic responses to common allergens / Istvan Boldogh, Leopoldo Aguilera-Aguirre, Attila Bacsi, Barun K. Choudhury, Alfredo Saavedra-Molina, Marian Kruzel
Dátum:2008
Megjegyzések:Colostrinin (TM) (CLN), isolated from mothers' pre-milk fluid (colostrum), is a uniform mixture of low-molecular-weight, proline-rich polypeptides. CLN induces neurite outgrowth of pheochromocytoma cells, extends the lifespan of diploid fibroblast cells, inhibits beta-amyloid-induced apoptosis and improves cognitive functions when administered to Alzheimer's disease patients. Objective: The aim of this study was to investigate potential allergic responses to CLN and its impact on allergic sensitization and inflammation caused by common allergens. Methods: We used a well-characterized mouse model of allergic airway inflammation. Changes in IgE/IgG1 and mucin levels, airway eosinophilia and hyperreactivity to methacholine were determined by ELISA, differential cell counting and whole-body plethysmography, respectively. Results: CLN did not increase IgE/IgG1 levels or induce cutaneous hypersensitivity reaction, airway inflammation and mucin production. Importantly, CLN significantly (p < 0.001) decreased IgE/IgG1 production, airway eosinophilia, mucin production and hypersensitivity induced by allergenic extracts from ragweed pollen grains and house dust mites. Conclusion: CLN itself is non-allergenic; however, it is effective in preventing allergic responses to known indoor and outdoor allergens. These data support the safe application of CLN and its potential use in the prevention of allergic inflammation in humans.

Cím:Class I HLA oligomerization at the surface of B cells is controlled by exogenous [béta]2-microglobulin : implications in activation of cytotoxic T lymphocytes / Bodnar A., Bacso Z., Jenei A., Jovin T. M., Edidin M., Damjanovich S., Matko J.
Dátum:2003
ISSN:1460-2377
Megjegyzések:Submicroscopic molecular clusters (oligomers) of class I HLA have been detected by physical techniques [e.g. fluorescence resonance energy transfer (FRET) and single particle tracking of molecular diffusion] at the surface of various activated and transformed human cells, including B lymphocytes. Here, the sensitivity of this homotypic association to exogenous beta(2)-microglobulin (beta(2)m) and the role of free heavy chains (FHC) in class I HLA oligomerization were investigated on a B lymphoblastoid cell line, JY. Scanning near-field optical microscopy and FRET data both demonstrated that FHC and class I HLA heterodimers are co-clustered at the cell surface. Culturing the cells with excess beta(2)m resulted in a reduced co-clustering and decreased molecular homotypic association, as assessed by FRET. The decreased HLA clustering on JY target cells (antigen-presenting cells) was accompanied with their reduced susceptibility to specific lysis by allospecific CD8(+) cytotoxic T lymphocytes (CTL). JY B cells with reduced HLA clustering also provoked significantly weaker T cell activation signals, such as lower expression of CD69 activation marker and lower magnitude of TCR down-regulation, than did the untreated B cells. These results together suggest that the actual level of beta(2)m available at the cell surface can control CTL activation and the subsequent cytotoxic effector function through regulation of the homotypic HLA-I association. This might be especially important in some inflammatory and autoimmune diseases where elevated serum beta(2)m levels are reported.

Cím:The CD45 tyrosine phosphatase regulates Campath-1H (CD52)-induced TCR-dependent signal transduction in human T cells / Hederer, R. A., Guntermann, C., Miller, N., Nagy, P., Szollosi, J., Damjanovich, S., Hale, G., Alexander, D. R.
Dátum:2000
Megjegyzések:Campath-1H, a humanized mAb undergoing clinical trials for treatment of leukemia, transplantation and autoimmune diseases, produces substantial lymphocyte depletion in vivo.The antibody binds to CD52, a highly glycosylated molecule attached to the membrane by a glycosylphosphatidylinositol anchor. Cross-linked Campath-1H is known to activate T cells in vitro. We have investigated the molecular basis for these effects by comparing the protein tyrosine phosphorylation signals induced by Campath-1H and the CD3 mAb OKT3 in primary T cells, and in CD45(+)TCR(+), CD45(-)TCR(+) and CD45(+)TCR(-) Jurkat subclones transfected with CD52. Our results show that Campath-1H triggers similar tyrosine phosphorylation events as OKT3 in both primary T cells and in the CD45(+)TCR(+) Jurkat sub-clone, albeit at quantitatively lower levels. However, no phospholipase C gamma 1 activation nor calcium signals were detected in response to CD52 ligation. The CD52-mediated induction of protein tyrosine phosphorylation was absolutely dependent upon the expression of both the TCR and the CD45 phosphotyrosine phosphatase at the cell surface. Cross-linking of Campath-1H was essential for signal transduction in all cells investigated. Fluorescence resonance energy transfer was used to demonstrate CD52 homo-association at the cell surface in Jurkat T cells in a TCR- and CD45-independent manner, and CD52-TCR association in CD45(+)TCR(+) cells. We propose a model to explain the activating effects of Campath-1H in which CD52 mAb cross-linking causes the trapping of TCR polypeptides within molecular complexes at the cell surface, thereby inducing signals via the TCR by a process which depends on the CD45-mediated regulation of the p56(lck) and p59(fyn) tyrosine kinases.

Cím:Clinical and laboratory examinations in the subgroups of chronic urticaria / Irinyi B., Széles Gy., Gyimesi E., Tumpek J., Herédi E., Dimitrios G., Ádány R., Hunyadi J., Szegedi A.
Dátum:2007
Megjegyzések:The aetiology of chronic urticaria is heterogeneous. Physical urticaria (PU) is estimated at around 35 %, autoimmune urticaria (AIU) at 25 % and chronic idiopathic urticaria (CIU) at 35% of all chronic urticaria cases. Methods: Differences in clinical and laboratory parameters among AIU, PU and CIU groups were examined. AIU was diagnosed if basophil CD63 assay was positive. Demographic data, severity of symptoms, and association with allergic and autoimmune diseases were analysed by the aid of an internationally accepted questionnaire a questionnarie. Immunoassays were carried out and the effectiveness of therapy was also investigated. Results: Female dominance in the AIU group was prominent. Concerning the urticaria score, there were significant differences between the AIU and PU patients (p=0.015) and between AIU and CIU cases (p=0.013). Between the CIU and PU patients, we found an insignificant difference in the urticaria score (p=0.78). AIU was more frequently associated with autoimmune diseases in the personal (p<0.001), and with other types of urticaria in the family history (p<0.001). Also anti-thyroid antibodies were more frequently detected in the AIU group. Antihistamine therapy was less effective in the AIU group (12.8%) than in the PU (70.3%) and CIU groups (68.6 %), but there were no significant differences between the CIU and PU groups regarding the effectiveness of antihistamine therapy. Conclusion: The autoimmune subgroup represents the most severe form of chronic urticaria. On the other hand between the CIU and PU groups there were no significant differences in urticaria scores as well as in response to antihistamine therapy.

Megjegyzések:Background: Interleukin (IL)-16 has been characterized as animmunomodulatory cytokine. Besides its chemotactic properties,IL-16 amplifies inflammatory processes and possessesimmunoregulatory functions. Our aim was to investigate theassociation between serum IL-16 levels and the degree of allergicsensitization in patients with atopic dermatitis (AD).Methods: The serum level of IL-16 was measured by immunoenzymaticassays. Eosinophil cell count, serum total andspecific IgE levels were assessed; prick tests were also carriedout. Based on specific IgE levels and prick tests, AD patientswere divided into sensitized and nonsensitized subgroups,and correlations among serum IL-16, total IgE levels and eosinophilcell counts were measured in the total patient groupand in subgroups. Results: In the total patient group, significantlyhigher levels of IL-16 were found in the sera of patientswith AD, compared to healthy individuals and patientswith psoriasis. A significant correlation was detected betweenserum levels of IL-16 and total IgE, total IgE andeosinophil counts, but not between IL-16 and eosinophils.

Cím:Expression and function of Toll-like receptors 2 and 4 in human keratinocytes / Andor Pivarcsi, Laszlo Bodai, Bence Réthi, Anna Kenderessy-Szabó, Andrea Koreck, Márta Széll, Zsuzsanna Beer, Zsuzsanna Bata-Csörgő, Mária Magócsi, Éva Rajnavölgyi, Attila Dobozy, Lajos Kemény

Megjegyzések:Keratinocytes have the ability to kill pathogenic fungi and bacteria by producing antimicrobial substances. Recent studies suggest that microbial components use signaling molecules of the human Toll-like receptor (TLR) family to transduce signals in various cells. Here we provide evidence that keratinocytes express both TLR2 and TLR4 at the mRNA and protein levels, and show that TLR2 and TLR4 are present in the normal human epidermis in vivo and that their expression is regulated by microbial components. The expression of myeloid differentiation protein gene (MyD88), which is involved in the signaling pathway of many TLR, was also demonstrated in keratinocytes. LPS + IFN-gamma increased the expression of TLR2 and TLR4 50- and 5-fold respectively. Treatment of keratinocytes with Candida albicans, mannan, Mycobacterium tuberculosis or LPS with IFN-gamma resulted in the activation and nuclear translocation of NF-kappaB. Inhibition of NF-kappaB blocked the Candida-killing activity of keratinocytes, suggesting that the antimicrobial effect of keratinocytes requires NF-kappaB activation. LPS + IFN-gamma, C. albicans (4 Candida/KC), peptidoglycan (1 micro g/ml) or M. tuberculosis extract significantly increased IL-8 gene expression after 3 h of treatment (P < 0.05). The increases over the 0-h level were 15-, 8-, 10.8- and 7-fold, respectively. The microbial compound-induced increase in IL-8 gene expression could be inhibited by anti-TLR2 and anti-TLR4 neutralizing antibodies, suggesting that TLRs are involved in the pathogen-induced expression of this pro-inflammatory cytokine. Our findings stress the importance of the role of keratinocytes as a component of innate immunity.

Cím:Non-pro-vitamin A and pro-vitamin A carotenoids in atopy development / R. Rühl
Dátum:2013
ISSN:1018-2438
Megjegyzések:Carotenoids are important derivatives of the human diet and occur in high concentrations in the human organism. Various carotenoids are also present in human breast milk and are transferred to breast-fed children. The alternative to breastfeeding is supplementation with an infant milk formula, but these formulas contain only a limited variety of carotenoids. Our question is: 'What is the function of various carotenoids in human nutrition with a special emphasis on child development and the development of atopy?' In this review, the mechanisms of action of the most important non-pro-vitamin A and pro-vitamin A carotenoids: α-carotene, β-carotene, β-cryptoxanthin, lutein, zeaxanthin, lycopene and retinoids are discussed. In summary, the combination of carotenoids, especially lycopene, seems to be of great importance, and exclusive usage of β-carotene in infant formula may yield in an increased atopy prevalence mediated in various target organs like the skin, lungs and immune competent cells. We conclude that the determination of novel bioactive metabolites of various carotenoids, at various stages in different organs during atopy development, might be the key to understanding the potential importance of carotenoids on atopy development.

Cím:Histamine modulates multiple functional activities of monocyte-derived dendritic cell subsets via histamine receptor 2 / Simon T., Gogolák P., Kis-Tóth K., Jelinek I., László V., Rajnavölgyi E.
Dátum:2012
ISSN:0953-8178
Megjegyzések:Expression of CD1a proteins in human monocyte-derived dendritic cells (DCs) specifies functionally distinct subsets with different inflammatory properties. Histamine is recognized as an inflammatory mediator released by various cell types including DCs. The diverse biological effects of histamine are mediated by G-protein-coupled histamine receptors (HRs), which are able to modulate the functional activities of DC subsets. The goal of the present study was to compare the expression and activity of HRs in the CD1a- and CD1a+ monocyte-derived DC subsets and to test the effects of histamine on the differentiation, activation and functional activities of these subsets. We show that H2R is present at high levels in both DC subsets, whereas H1R and H4R are expressed in a subset-specific manner. Histamine shifts DC differentiation to the development of CD1a- DCs and modulates DC activation through its inhibitory effect on CD1a+ DC differentiation. Histamine-induced reduction of CD1a+ DCs is associated with increased secretion of IL-6 and IL-10, up-regulation of a typical combination of chemokines, expression C5aR1 by the CD1a- DC subset and enhanced migration of both activated DC subsets supported by the production of MMP-9 and MMP-12 enzymes. All these effects were shown to be mediated in a H2R-specific manner as revealed by the specific antagonist of the receptor. As H2R is expressed at high levels in both DC subsets, we propose that it may dominate the regulation of multiple DC functions. In contrast, H1R and H4R with opposing subset-related expression may have a regulatory or fine-tuning role in histamine-induced functional activities.
