Development of selected CD markers and their role in the phylogenesis of human immune system
Podolská, Tereza ; Růžičková, Šárka (advisor) ; Vinkler, Michal (referee)
In the first part of the thesis we investigated the origin of selected surface CD markers of human, namely CD19, CD20, CD21, CD24, CD27 and CD38 molecules. In addition, nucleotide and amino acid sequences of these molecules were compared using in silico approach. Bioinformatic databases of sequences of selected molecules at DNA, mRNA and protein level, such as GeneBank, NCBI BLAST, Homologene and OrthoDB, have been used. The intent was to identify at the domain level the first organism in which it is possible to find the searched molecule. At the N-terminal domain of the CD38 of birds, a sequence showing significant similarity to the archaebacterial flagellin domain was found. This flagellin sequence in the CD38 avian molecule is located in the region of transmembrane domain, indicating that the occurrence of this sequence might be related to the formation of the transmembrane domain. The approach used here could be implemented in comparative hybridization studies as a tool in the preparatory non-laboratory phase of the research of the presence of paralogs and orthologs in phylogenetically old species. Keywords: CD marker, immunocyte, B lymphocyte, innate and adaptive immunity, sequence database, amino acid, nucleotide

Leukaemia associated immunophenotype in childhood acute leukaemias and its development during the course of disease
Podolská, Tereza ; Fišer, Karel (advisor) ; Drbal, Karel (referee)
Acute lymphoblastic leukaemia (ALL) is the most frequent childhood malignancy. One of the recent improvements in ALL treatment was the introduction of minimal residual disease (MRD) monitoring that enables risk stratification based treatment adaptation. The same MRD monitoring helps to choose relapse treatment, to guide indication for stem cell transplantation (SCT) and allows for a more personalized management of patients undergoing SCT. One of the main routes of MRD levels detection is characterisation of leukemic blasts using flow cytometry. However, flow cytometry is limited by its mainly manual expertise-based analysis. Such analysis is subjective and clearly insufficient for current complex data. While new computational tools are available for multidimensional flow cytometry data, there is an urgent need to test and adapt them for the use in clinical environment. The goal of this thesis is to detect immunophenotypes associated with leukaemia and their development by leveraging machine-assisted analysis of a set of diagnostic files selected based on information about more than three hundred thousand of multiparameter flow cytometry datasets. Advanced bioinformatic tools will help to detect blast and healthy haematopoietic populations, to derive their immunophenotypes and to identify individual...
