Head of the Group

The projects of the Cell Biology Group are complex multidisciplinary studies involving a wide range of specialists: from the laboratories of the Institute of Molecular Biology and Genetics, Heart Failure Research Laboratory, bioinformaticians of the Genomic Diversity Centre of ITMO University, the Laboratory of Myology of the Institute of Biomedical Problems of the Russian Academy of Sciences, the Department of Human and Animal Physiology of Lomonosov Moscow State University.

Major research areas

  • Study of the mechanisms of impaired skeletal muscle regeneration and metabolism in cardiovascular diseases, including chronic heart failure and laminopathies
