Trans-species polymorphism in immune genes at wildlife animals
Těšický, Martin ; Vinkler, Michal (advisor) ; Matiašovic, Ján (referee)
Trans-species polymorphism (TSP) is described as the occurrence of identical or similar alleles in related species, excluding cases where the similarity arose by convergence. In TSP the alleles are inherited from ancestor to the descendant species. Neutral TSP is frequent in closely related newly diverged species and it gradually disappears. Considering evolution of immune system and host- pathogen interaction, balanced long-lasted TSP is much more important. Balanced TSP in immune- related genes is maintained by the mechanism of balancing selection and commonly persists for millions of years. In my thesis I map the contemporary knowledge on TSP in immune-related genes, focusing mainly on wild animals. The chief emphasis is given to evolutionary mechanisms influencing the width and age of TSP, distinguishing TSP from other TSP-like evolutionary patterns and methodical difficulties with the assignment of TSP. Presently, most articles dealing with TSP concentrate only on genotyping the Major histocompatibility loci (MHC I and MHC II), especially in the peptide binding region. Our knowledge concerning other immune genes with putative TSP is, therefore, insufficient. Most importantly, this is true for innate immunity genes. More effort should be given to comparative large-scale well-sampled studies...

New ferritin nanoparticles for specific targeting of experimental melanoma in mice: in vitro and in vivo tests.
Rajsiglová, Lenka ; Vannucci, Luca Ernesto (advisor) ; Šírová, Milada (referee)
Cancer diseases represent second most frequent cause of death after cardiovascular diseases in Europe. Nowadays used medical treatments like chemotherapy and radiotherapy are nonspecific and cause huge side effects. Various systems to deliver therapy directly inside the tumour microenvironment and reduce side effects are under development. Protein nanoparticles seem to be very promising strategy to achieve that goal. Our group in cooperation with CNR in Rome tested nanoparticles based on heavy chain of human ferritine. These constructs, modified to expose the tumor targeting molecule, were able to be specifically internalised by B16F10 melanoma cells in vitro. They also specifically target and localise at the sites of primary melanoma and lung metastases of different size in mouse in vivo model. These nanoparticles can carry either therapeutic or diagnostic molecules. Thus they represent a suitable candidate for further studies for potential use in clinical praxis as a diagnostic and/or therapeutic agents (theranostics). Powered by TCPDF (www.tcpdf.org)

The Position of the Czechoslovakia Senate in the Political System in the First Republic
Kouřimský, Jan ; Pehr, Michal (advisor) ; Polášek, Martin (referee)
The goal of this thesis is to show the life and functioning of the Senate of the National Assembly of Czechoslovakia. The upper house of the Czechoslovak Parliament functioned between 1920 and 1939 after which it was officially dissolved during the Protectorate of Bohemia and Moravia. In the concerned period, the chamber was gradually saw 444 lawmakers of seven different nationalities. The biggest number consisted of Czechs and Germans. The functioning of the Senate is analyzed from multiple angles. First the debate accompanying the establishment of a second chamber before the adoption of the new Constitution in 1920 is analyzed. Attention is also paid to the period debates and unrealized proposals for a Senate reform at the end the 1920's, linked to the proposed creation of the Economic Parliament. Also shown is the proportional representation electoral system used for elections to the Senate. The results were reflected in a large number of political parties with low electoral gains, which in turn hindered the creation of a stable political environment. The thesis considers the party, ethnic, social, intellectual and oratory activities of individual senators. The lives of some of the lawmakers who held seats in the upper chamber in the First Republic and were negatively affected by the German...

Changes in expression of immune-related genes after induction of inflammation in birds
Pojezdná, Anežka ; Vinkler, Michal (advisor) ; Chudíčková, Milada (referee)
Inflammation is one of the most important immunological mechanisms that protect animals from diseases. In my thesis I summarized information on changes in gene expression in tissues in the course of the inflammatory immune response in birds. I tried to describe the main features of the immune response in birds and highlight the differences to other vertebrates, especially mammals. I focused mainly on the surface molecules of various types of immune cells, as well as on signalling by soluble factors called cytokines. Although in general features are the inflammatory reactions in birds and mammals similar, in my thesis I have shown that a large portion of mediators and signalling molecules work very differently in these two vertebrate groups (e. g. the TNF SF-mediated pro-inflammatory signalling) and that substantial variation many be found even between different species of birds.

Translational control in immune response.
Hlaváček, Adam ; Valášek, Leoš (advisor) ; Čáp, Michal (referee)
Immune reaction often requires a prompt modification of gene expression that in turn alters cellular physiology. There are an increasing number of articles supporting a critical role of translational control in this aspect of cellular biology. The aim of this work is to present some of cellular and molecular mechanisms that connect translational control and immune reaction in immune and somatic cells and can be possibly misused by some viruses. Perhaps not surprisingly, many immunologically relevant translational control mechanisms are similar to those acting during the stress response. Over the years it has been documented that the T cells, dendrocytes, Natural killer cells and macrophages utilize translational control for their immunological activation following stimulation. Combination of general and gene-specific translational control mechanisms enables fast changes in proteome and physiology that are characteristic for immune cell activation. The overall impact of translational control on immune response is further illustrated by the fact that it acts upon each stage of life of immune cells - from their activation, through survival, to a programmed cell death. Even in some non-immune cells the translational control plays an important role with respect to immunity, as these cells are known to have an...

Patková, Lucie ; Šturma, Pavel (advisor) ; Faix, Martin (referee)
The thesis deals with topic of universal jurisdiction with an emphasis on British House of Lords' decisions in case of former Chilean president Augusto Pinochet from years 1998 and 1999. Universal jurisdiction enables to prosecute crimes committed abroad by persons, who at time of such commission were neither the citizens of state in question nor the permanent residents of the state. It is expression of an idea, that it is common interest of the whole international community to prosecute the most serious crimes under international law, irrespective of any link to the prosecuting state, because such crimes relate to the whole international community and not only single state. The first chapter of the thesis deals with national criminal jurisdiction, whose comprehension is necessary for further understanding of universal jurisdiction. The universal jurisdiction is the main topic in the second chapter, in which I outline a brief history of the concept, mention application of the universal jurisdiction in case with Adolf Eichmann in Jerusalem, and try to find out where the importance of universal jurisdiction lies or what the main alleged disadvantages and risks are as well. My further concerns are the scope of universal jurisdiction, that is the crimes that are subjects to its application, universal...

Effect of inhaled IgY and Fab fragments on the lung inflammation
Majerová, Barbora ; Hodek, Petr (advisor) ; Koblas, Tomáš (referee)
Human respiratory system is in constant contact with heterogeneous environmental agents, which can possibly become initiators of inflammatory responses. Mechanical barriers and balance between the innate and adaptive immunity provide protection from external agents without initiation of any inflammatory response. Under certain circumstances, overreaction of the immune system might occur and leads to the production of various inflammatory cytokines and mediators such as TNF-α and GM-CSF factors or interleukins IL-1ß and IL-6. Respiratory system of the human suffering from cystic fibrosis is unable to defend against bacterial infections effectively. Chicken egg immunoglobulins (IgY) could eventually become a suitable tool for the protection from opportunistic pathogens, because they, when bound to antigen, don't activate the complement cascade. One method of determining the immunogenicity of the studied agent is the exposure of experimental animal and further measurement of inflammatory cytokine concentration. In this thesis, the potential inflammatory effect of IgY, IgY-derived Fab fragments and ovalbumin was determined after an exposure of Wistar rats by long-term inhalation. Correct implementation of inhalation experiment was confirmed via production of specific antibodies against the inhaled...

Stropková, Romana ; Hošťálková, Monika (advisor) ; Strnadová, Alice (referee)
The bachelor thesis is focused on the problems of the food allergies. The aim was to discover how much the population is informed in this field, if the population has experienced the food allergies, having found the symptoms present on themselves or their friends, family. And finally the awareness of these allergies in a family taking care of an allergic person is studied. In the theoretical part the definitions of the food allergies and similar reactions are explained. It is followed by anatomical and physiological descriptions of digestive and immune systems which are closely related to the food allergy. The causes and symptoms of the food allergies, diagnostics, treatment and prevention are integral to the theoretical part. The importance of probiotics and prebiotics which differs in scientists' opinions and in results of scientific studies is also studied. In the end of this chapter a new antigen and the education of the general public are mentioned. In the empirical part the characteristics of research assignment and methods of the research are described. I chose a questionnaire as a method for data collection. I deal with the results of the questionnaires in this part too. Research shows that the majority of respondents knows what the food allergy is and have an idea of its causes and...

Autophagy in the immune system
Vávra, Dan ; Černý, Jan (advisor) ; Janštová, Vanda (referee)
Autophagy is an essential, homeostatic process - survival mechanism that protects cells by various ways: cells break down their own components to recycle nutrients, remodel and dispose unwanted cytoplasmic constituents. Autophagy is involved in the degradation of long-lived proteins and entire organelles, but paradoxically, considering important prosurvival functions, autophagy may be deleterious. It plays an important role during development, tumor suppression, immunity and is required for the adaptation to environmental stresses such as starvation. Recent studies indicate, that autophagy is a central player in the immunological control of bacterial, parasitic and viral infections. The process of autophagy may degrade intracellulal pathogens. This work describes the mechanism of autophagy and highlights the role of autophagy in innate and adaptive imunity, summarizes some advances in understanding the functions of autophagy and its possible roles in the causation and prevention of human deseases.
