BAFF (B-cell Activating Factor of the TNF Family) in patients with idiopathic inflammatory myopathieswith respect to autoantibody profile.
 Kryštůfková, Olga ; Vencovský, Jiří (advisor) ; Tlaskalová - Hogenová, Helena (referee) ; Blažíčková, Stanislava (referee)
The idiopathic inflammatory myopathies (IIMs) are a heterogeneous group of chronic muscle diseases with frequent extramuscular organ involvement that contributes to serious prognosis. The presence of autoantibodies and composition of muscle infiltrates both support autoimmune nature of the disease and pathogenic role of B lymphocytes. Besides the traditional diagnostic subgroups, autoantibody characterised phenotype subsets have been identified with presumed similar pathogenic mechanisms. The best known is the antisynthetase syndrome which is characterised by presence of myositis, antisynthetase autoantibodies (with anti-Jo-1 being the most frequent), interstitial lung disease and other extramuscular manifestations. BAFF (B cell-Activating Factor of the TNF Family) is a key factor in B cell homeostasis modulation. In high levels, it allows survival of autoreactive B cell clones and thus participates in the pathogenesis of autoimmune diseases. Its expression is induced by type I interferons (IFN-1). The aim of the PhD thesis was to explore the role of BAFF in pathogenesis of IIMs by analysis of its serum levels, the receptors for BAFF in muscle tissue, their associations to IFN-1 and expression of BAFF gene mRNA transcription variants in peripheral blood cells. Further aspect was to study a possible...

Study of Common Pathogenetic Factors of Alzheimer Disease and Type 2 Diabetes Mellitus
 Vacínová, Gabriela ; Vaňková, Markéta (advisor) ; Lukášová, Petra (referee)
Alzheimer's disease (AD) and type 2 diabetes mellitus (T2DM) are aging-associated diseases that have rising prevalence in all industrialized countries. AD is a neurodegenerative disease characterized by progressive loss of cognitive functions. It is a complex disease which formation involves both genetic factors and environmental factors. The most important marker associated with this disease is the risk allele ε4 in APOE gene. From the latest genome-wide association study emerged another ten candidate genes. As the most significant from those genes appears the minority G allele of rs744373 polymorphism in the gene BIN1. AD is connected with many metabolic and immune disorders. To the markers of interest belongs also the new parameter visfatin which can act as a pro-inflammatory cytokine. T2DM is a chronic disease characterized by raised levels of blood glucose, which is also characterized by neurological disorders. In the case of both of these diseases can be found a large number of metabolic disorders. One of the most important disorders is insulin resistance. This thesis consists of two parts - the biochemical and genetic one. The biochemical part of the thesis studies the visfatin level in patients with AD and healthly control and studies whether visfatin is related to AD. In this part of the...
