The research infrastructure on experimental studies and applications of cellular processes aims at gathering national know-how in the field of cell and molecular biology, and aims at setting up an instrumental capability to develop competence and services in the fields of microbial and mammalian cell processes and their applications. The infrastructure will be built up jointly by the University of Tartu, Tallinn University of Technology, Tallinn University, Estonian University of Life Sciences and the Institute of Chemical Physics and Biophysics. The vision is to become a know-how and service centre to partner health, biotechnology and environment-focused public sector organisations, medical institutions, biotechnology and pharmacological companies. The focus will be on acquiring and setting up relevant instrumental complexes, development and offering of services, popularisation and dissemination of the field in order to ensure sustainability of researchers and future activities.

In heart muscle cells, energy is transferred from mitochondria to multiple locations in the cell, where it is utilized to perform mechanical work and maintain ion balance. On the molecular diffusion pathway, several intracellular structures impose restrictions, which are prominent in healthy cells and, some data suggests, disappear in disease. While the restrictions and some clinical data point towards a major role of creatine kinase (CK) assisted energy transfer in the cell, data from loss-of-function animal models are equivocal. In this project, we will develop and use state-of-the-art experimental and mathematical modeling approaches to characterize the diffusion environment within cardiomyocytes and quantify the role of CK in the healthy heart. By identifying the adaptations in transgenic mice, we expect to identify new treatment targets for heart failure patients with reduced CK flux.
