Research subject for a potential FP6 project

Biological membranes are heterogenous assemblies of lids and proteins whose biogenesis and functions are controlled by a network of interacting genes. Membrane functions linked to intracellular transport, information processing and to energy transformation are profoundly involved in normal functioning of cells. Current state of knowledge about membrane structure and functions substantiates an integrative approach to diverse aspects of normal and pathological cellular processes from the perspective of membranes. Research project should cover structure – function analysis of biomembranes in organisms of various evolutionary complexity with relevance to human or animal health. The emphasis should be given on following aspects of membrane research: 1. Membrane structure and functions as adaptive factors in the evolution of living systems; 2. Role of membranes in the regulation of cell homeostasis with respect to the etiology of selected diseases; 3. Principles of membrane participation in energy transformation and information processing; 4. The study of artificial membranes and their biotechnological application.Conceptual and methodological design of the project should highlight the interdisciplinary approach to the study of membrane functions combining the functional genomics, integrative metabolic studies and biophysical analysis of membranes with cellular physiology and pathophysiology. The contribution of our institute could involve the evolutionary aspects of cell bioenergetics with the emphasis on mechanisms of energy transformation in ancient organisms (Archaea), regulation of membrane biogenesis and its impact on the physiology of normal and diseased cells, and application of the principles of membrane organisation in the construction of biosensors.
