Abstract
Structure and function of biological membranes will be investigated as well as the interaction of biologically active substances and liposomes - vectors for the targeted delivery of drugs, with cells and tissues. The method is based on the semi- or non-destructive investigation of membranes and interactions in cells and tissues in situ and in vivo. In this project we will study membrane transport, binding and partitioning of hydrophobic molecules, mechanisms of formation of free radicals, the reactive intermediates important in series of biologically relevant lipid transformations, as well as the conformation of proteins and lipid-protein interactions in lipoproteins. The influence of lipid composition in liposome membranes as well as their size and lamelarity on the liposome stability and their interaction with cells and tissues will be also investigated. This will contribute to better understanding of the mechanism of action of membranes and their interactions with biologically active molecules and to the development of the methods for more rational transfer of drugs to the desired place in the cell or organism.
