Inhibitory NK cell receptors and possibilities of manipulation of cytotoxic properties.
Švubová, Veronika ; Frič, Jan (advisor) ; Krulová, Magdaléna (referee)
Acute myeloid leukemia makes up for 18 % of all leukemias among pediatric and young adult patients. The complete remission rate (80-90 %) and the overall survival (70 %) of the patients is relatively high, nevertheless, the relapse rate is still almost at 50 % and the prognosis remains extremely bad. The relapse treatment is rather challenging because the persisting leukemic clones might in fact start to be refractory to chemotherapy. Lately, NK cells are being perceived as an attractive therapeutical tool for treatment of the relapses. NK cells are a subpopulation of innate lymphoid cells, possessing the ability to eliminate dysfunctional cells through cytotoxic activities and further perpetuate the immune response. One of the advantages of NK cells is their functional independency of specific antigens. In the light of growing evidence about the role of leukemic stem cells in context of acute myeloid leukemia, NK cells seem to offer a new perspective in therapeutical efforts to eliminate them via several cytotoxic mechanisms. Yet despite optimistic preliminary results, treating this disease has proved to be rather challenging and the NK cell-based immunotherapy is still facing several limitations. Transforming growth factor β is partially responsible for maintenance of leukemic stem cell...
