Investigation of the molecular mechanisms of elimination of clinically relevant tumors by killer cells of the immune system.
Libigerová, Martina ; Bezouška, Karel (advisor) ; Bosáková, Zuzana (referee)
Carbohydrates have an essentials role in wide range of biological phenomena. It is well known that most of the eukaryotic proteins are glycosylated and that their glycosylation undergoes dynamic changes, nevertheless the biological imperative for these modifications is still not fully understood. However, one area in which the importace of cell surface glycosylation has recently been the subject of active investigations is the tumor plasma membrane biology, where many changes in glycosylation have been found useful for diagnosis, and mostly recent, even for the therapies of malignant disease. Interestingly cell surface glycoconjugates, namely N-linked and O-linked oligosaccharides have been found therapeutically attractive for treatment of certain tumors. And although our understanding of the participation of these principal glycan classes in tumorigenesis is far from complete, there are already several examples of carbohydrate-based antitumor vaccines. Therefore, we decided to give this issue more attention, especially the molecular mechanisms responsible for identifying changes in glycosylation of the surface of tumor cells of the immune system. Although in the past in our laboratory identified a receptor-type lectin specific lectin receptors on natural killer cells, very little is yet known...
