Study of interleukin 37 and its role in rheumatoid arthritis
Jandová, Romana ; Šenolt, Ladislav (advisor) ; Krulová, Magdaléna (referee)
Dysregulation between pro- and anti-inflammatory cytokines activity in rheumatoid arthritis (RA) contributes to immune dysregulation, chronic inflammation and subsequent joint destruction. Interleukin-37 (IL-37) has been described as an anti-inflammatory cytokine in several autoimmune diseases. The main aim of this work was to determine the levels of IL-37 in serum and synovial fluid (SF) of RA patients and to compare them with the levels in patients with osteoarthritis (OA) and further explore the association of IL-37 with disease activity and other clinical parameters. Subsequent goal was to study its anti-inflammatory function on RA synovial fibroblasts and describe other cells types of synovial tissue contributing to its production. IL-37 levels were detected using enzyme-linked immunosorbent assay (ELISA). Synovial fibroblasts were stimulated by lipopolysaccharide (LPS) and recombinant IL-37 (rIL-37). The levels of studied genes were detected by PCR. Synovial tissues and immune cells were visualized by immunohistochemical and by immunofluorescence staining. We found increased levels of IL-37 in SF of patients with RA in comparison to OA patients. There was a significant correlation between serum and SF levels of IL-37. RA as well as OA patients showed increased levels of IL-37 in serum than in...

Th17 lymphocytes and autoimmunity diseases with the intention of diabetes 1. type
Labiková, Jana ; Štechová, Kateřina (advisor) ; Procházková, Jana (referee)
Th17 cells were recently identified as a cell source of IL-17. They turned up to be a T cell lineage independent of previously described Th1 and Th2. The differentiation of naive CD4+ T cells towards Th17 requires the combination of TGFβ (a cytokine essential for the development of anti-inflammatory regulatory T cells) plus IL-6 or IL-21. IL-23 is required for in vivo function and phenotype maintenance of Th17. STAT3 and RORγt were identified as pivotal transcription factors in Th17 differentiation program. Th17 proved to have pro- inflammatory effects and are characterized by the production of IL-17A, IL-17F and IL-22 - cytokines implicated in host defense against certain extracellular pathogens. The cytokine products of Th17 cells act on wide range of cell types. They induce cytokines, chemokines and metalloproteinases and they also mediate neutrophil recruitment and production of antimicrobial peptides. Autoreactive Th17 are highly pathogenic and the production of IL-17 has been detected in several autoimmune diseases such as rheumatoid arthritis, multiple sclerosis, psoriasis, Crohn's disease and type 1 diabetes. These diseases were thought to be mediated by Th1 cells, but it is becoming increasingly clear that the regulation of autoimmunity is influenced at least in some diseases by Th17 cells as well.

Interpretation of Common Used Tumor Markers Affectedy by Systemic and Inflammatory Diseases
Čásová, Miroslava ; Topolčan, Ondřej (advisor) ; Ludvíková, Marie (referee) ; Šafarčík, Kristian (referee)
Interpretation of Common Used Tumor Markers Affected by Systemic and Inflammatory Diseases Introduction: An examination of tumor markers is often made as a basis for the successful diagnosis and follow-up treatment of patients with malignant tumors. However, are tumor markers truly significant by themselves, or are they just a baseline quantitative expression of value that we use to diagnose a patient as better or worse based on it increasing or decreasing value? Objective: This paper attempts to answer the question of what factors can affect serum protein and mucin markers and thus lead to a misinterpretation of their results. Methods: Tumor markers were determined by isotopic and non-isotopic laboratory analysis methods, using operational protocols of the immunoanalytic laboratory. All methods were checked using internal quality control, and four times a year using an external quality control. Additionally, 16 236 samples were analysed using 3180 probands during the period 2008-2014. Results: We discovered that in premenopausal women, the markers AFP, CA 125 and HE 4 rise during ovulation peak periods while other markers changed minimally or not at all. However, in postmenopausal women, we proved the incidence of a false positivity marker. With women in the 1st and 2nd trimester of pregnancy, the...

The role of microbiome in celiac disease
Tučková, Kateřina ; Konečná, Klára (advisor) ; Jílek, Petr (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Subject of study: Healthcare bioanalytics Student: Kateřina Tučková Supervisor: RNDr. Klára Konečná, Ph.D. Title: The role of microbiome in celiac disease Background: Descriptions of the celiac disease problematics. Focus on the origin of the disease and its possible connection and role of the intestinal microbiome. Define the term microbiome and point out its possible role in human health. Finally, address the attention to possibilities in the treatment of celiac disease. Main findings: The role of the microbiome in celiac disease and other diseases is a frequently discussed topic. Patients with the celiac disease diagnosis depend on a lifelong gluten-free diet. The microbiome is highly specific to and is affected by many external stimuli, which can often be affected. Current studies point to a linkage between the microbiome and many diseases, including celiac disease. Conslusions: More knowledge is needed for the complex insight into the problematics of the relationship between celiac disease and the microbiome. In general, the microbiome composition has a much more significant impact on human lives than previously thought. Intestinal microbiome imbalance is related to celiac disease...

Comorbidity of psychical and autoimmune diseases
Kaňková, Zuzana ; Šolc, Roman (advisor) ; Mravec Bencúrová, Dominika (referee)
Mental and autoimmune disorders represent a wide range of different diseases and are currently one of the most common health problems. In recent years, a significant association between these two types of disorders has been observed, supported by both their frequent coexistence and other important findings such as shared genetic risk factors, the discovery of neuronal surface antibodies or immune system changes related to some mental disorders. This work attempts to map the autoimmune diseases that occur more often or rarely in patients with various mental disorders (and vice versa) and also describes possible mechanisms that may play a significant role in the development of this phenomenon. Key words mental disorders, autoimmune diseases, comorbidity, etiology, epidemiology, shared risk factors

Maternal and fetal microchimerism.
Hynková, Marie ; Tlapáková, Tereza (advisor) ; Pačes, Jan (referee)
Microchimerism is defined as the presence of small amount of genetically distinct cells in one individual. It most often arises during pregnancy and breastfeeding. It can also arise from blood transfusion or organ transplantation. During pregnancy there occurs a bidirectional migration of cells through the placenta between the mother and the fetus. Cells which are transferred during pregnancy and breastfeeding can persist in the offspring until adulthood. During breastfeeding, a big number of immune cells is transferred to the offspring via mother's milk. These cells protect the offspring against pathogens and are involved in modulation of its immune system. Fetal cells persist in mother organism even decades after giving birth and can have long-lasting effect on mother's health condition. These fetal cells can help to regenerate mother's damaged tissues, but they can also contribute to the development of serious autoimmune diseases.

The Mechanism of Pathogenesis of Experimental Autoimmune Uveitis and Possilbilities of Their Regulation
Klímová, Aneta ; Heissigerová, Jarmila (advisor) ; Pitrová, Šárka (referee) ; Holáň, Vladimír (referee)
Introduction:Uveitis in an ocular inflammation affecting mostly people of working age. Uveitis is responsible for severe visual impairment despite of expanding new therapeutics. The animal models of uveitis were established, because the wide clinical variability of uveitis limits the studies in human medicine. The goal our project was to establish a reproducible model of experimental autoimmune uveitis in Czech Republic, and further on this model to observe the frequency of CD3+ and F4/80+ cells in retina, to assess the influence of microbial environment on intensity of intraocular inflammation and to test the therapeutical possibilities. Material and methods: The C57BL/6J mice were immunized by retinal antigen (IRBP 1-20, interphotoreceptor retinoid binding protein), enhanced by complete Freund's adjuvant and pertussis toxin and mild posterior autoimmune uveitis was induced. The mice were bred in conventional and germ-free (gnotobiotic) conditions. The uveitis intensity was evaluated in vivo biomicroscopically and post mortem histologically on hematoxylin eosin stained sections according to the standard protocol. The histological eye specimen were analyzed also by imunohistochemisty and by flow cytometry. Each experiment was performed for 35 days. The conventional mice with uveitis were treated...

Quality of life with scleroderma
Bendlová, Iva ; Tomášková, Anežka (advisor) ; Anděl, Michal (referee)
This bachelor thesis deals with the evaluation of the quality of life with scleroderma, a chronic autoimmune disease. The work is focused on determining the health-related quality of life of patients with localized and systemic scleroderma. The values obtained are then compared with the quality of life of the healthy population and with the health-related quality of life of the patients with selected diseases (psoriasis, systemic lupus erythematosus, rheumatoid arthritis and breast cancer). The research was conducted in the form of a randomized SF-36 questionnaire, a globally used tool for assessing the quality of life in chronically ill patients, which evaluates 8 areas of life. The results of the SF-36 questionnaire were further evaluated by T-test to determine statistically significant values. This questionnaire was further extended by supplementary questions. The results show that patients with scleroderma do not achieve the same quality of life as a healthy population in all evaluated areas. Patients with scleroderma rate their quality of life worse than all selected diseases (except for patients with localized scleroderma compared to those with systemic lupus erythematosus). Keywords - scleroderma - localized scleroderma (morphea) - systemic scleroderma - quality of life (QoL) - health related...

Mesenchymal stem cells and their effects on regulatory B cells
Smolová, Helena ; Boháčová, Pavla (advisor) ; Stříž, Ilja (referee)
Mesenchymal stem cells (MSC) are multipotent cells with the ability to regulate reactivity of cells of immune system. Regulatory B cells (Bregs) are also capable of modulating immune responses. Both these cell types are able of creating anti-inflammatory and tolerogenic environments and represent potential of cell-mediated therapy for autoimmune diseases and transplantation reactions. The effect of MSC on Bregs activation and function has been only studied in recent years, and mechanisms of their effects are not yet well characterized. However, studies have demonstrated a decrease in effector B lymphocytes and antibody production, and a support of activation of Bregs subpopulation and increased production of anti-inflammatory interleukin 10. Various molecules produced by MSC are involved in Bregs induction. Unfortunately, their effects have not yet been sufficiently described, and different models yields diverse results. In addition to the current studies in experimental models, the first clinical trials on Bregs have been initiated. The positive results suggesting the potential for future use of Bregs for the treatment of autoimmune diseases and transplantation reactions have been obtained in both cases. Key words: regulatory B cells, mesenchymal stem cells, immunomodulation, autoimmune diseases,...
