Použití imunomodulace pro potenciaci chemoterapie polymerními cytostatiky
Chmelová, Helena ; Kovář, Marek (vedoucí práce) ; Drda Morávková, Alena (oponent)
Cancer treatment with polymer-bound cytostatic drugs and its potentiation through immunomodulation Poly[N-2-(hydroxypropyl)-methacrylamide] (PHPMA) is a synthetic water soluble and biocompatible polymer which can be used as a carrier of a cytostatic drug and an antibody as a targeting moiety. The antibody ensures the site-specific delivery of the conjugate. Nevertheless, even polymeric conjugates without any tumor-specific targeting moiety are passively accumulated within solid tumors via so called Enhanced Permeability and Retention (EPR) effect, in case that their molecular wight is at least 40 kDa. Antibody-targeted polymeric drugs have been shown previously to have a cytostatic activity in vitro and an antitumor activity in vivo. Since treatment of cancer diseases in practice is far from such ideal conditions and many tumors have no strictly specific marker suitable for targeted therapy, upgrading of the treatment efficacy represents the major challenge. One of the possible ways how to improve insufficient chemotherapy outcome can be using of a combination of polymer-bound cytostatic drug and potent immunomodulation able to induce a robust anti-cancer immune response. In this study, we have used B cell leukemia BCL1 as an experimental tumor model. BCL1 cells express surface IgM with an unique...
