Dendritic cells in health and disease
Horváth, Rudolf ; Špíšek, Radek (advisor) ; Krejsek, Jan (referee) ; Stříž, Ilja (referee)
During the past decades several spectacular finding s have been made in the field of immunology. Elucidating the functions of the antigen presenting cells (APCs) belong to the most important. Dendritic cells (DCs) represent a specific group of APCs with a unique ability to initiate primary immune responses. Despite the fact that, in vivo, they are very rare and difficult to isolate, DCs came very fast into the focus of scientific interests. Development of novel laboratory techniques facilitated a robust expansion of their research. With time it has been proven that DCs play a pivotal role in initiation, maintenance and control of the immune responses. The extraordinary features of DCs were soon investigated in human clinical trials, where DCs have been particularly used as vectors for vaccination protocols, especially in the treatment of tumors. However, DCs capability to polarize the outcome of immune response and the potential to induce or suppress immunity under specific circumstances led to the idea that they might be also used in the treatment of autoimmune and allergic diseases or in transplantation medicine as well. There is a need to stress that most of the knowledge has been obtained from the in vitro generated DCs, but advanced technological methods bring us the opportunity to study DCs directly...

Dysregulation of immune system in the patients with Common Variable Immunodeficiency
Milota, Tomáš ; Horváth, Rudolf (advisor) ; Stříž, Ilja (referee) ; Freiberger, Tomáš (referee)
This thesis includes set of published experimental results, which were obtained at the Department of Immunology, Second Faculty of Medicine Charles University within the project focused on the basal and applied research of the Primary immunedeficiencies (PID), particularly Common variable immunodeficiency (CVID). The first, theoretical part, is divided into two sections. The first section is dedicated to the general aspects of Primary antibody deficiencies (PAD). The second section is focused on epidemiology, ethiopathogenesis, classification, clinical and therapeutical aspects of CVID. The main consideration is devoted particularly to non-infectious complications, which significantly contribute to morbidity and mortality of CVID patients. The second part consists of the set of publications describing specific mechanisms of immune system dysregulation and their clinical manifestation, which are briefly commented. The spectrum of issues resolved within the project covers following basic aspects: 1) characteristics of lung complications in CVID from the point of view of bronchial asthma, 2) characteristics of associated malignancies, 3) significance of genetic background for the specific treatment, 4) therapy of CVID focused on aspects of immunoglobulin substitution. The results of the other...
