Our research program focuses are physical capacity and cardiovascular and skeletal muscle remodelling in healthy (young) individuals, in aging and in various diseases such as heart failure and intensive care unit (ICU) patients. Our main target tissue is skeletal muscle but other tissues/organ systems in our research programs are the myocardium and the vascular system.  Our approach is to be integrative and have a translational approach to create and use tools to answer specific scientific questions.

Our research program focuses are physical capacity, cardiovascular and skeletal muscle remodelling in healthy young individuals, in aging and in various diseases such as heart failure and intensive care unit (ICU) patients. Our main target tissue is skeletal muscle but other tissues/organ systems are included in our studies, such as the myocardium and the vascular system.  

The first component in our research program is to investigate mechanisms in healthy subjects, including signalling pathways involving capillary growth, mitochondrial biogenesis and protein synthesis in the skeletal muscle response to increased physical activity. At present, the focus in these projects includes analyses of satellite cells, circulating pluripotent cells and matrix degeneration in skeletal muscle remodelling.

Another important aspect of our research is to study the influence of gender on cardiovascular and skeletal muscle function,  by investigating these organ systems before and after sex reassignment. This will enable an evaluation regarding the effects of sex steroids on these systems in adult humans.  The second component is related to the changes in skeletal muscle structure and function involved, primarily or secondarily, in various diseases and states, such as heart failure, in ICU patients and in aging. In these conditions the importance of intrinsic skeletal muscle changes is well documented, and a common denominator is neuroendocrine stress. Beyond the processes described above, at present our aim is to investigate the importance of calcium disturbance in reduced skeletal muscle function and activation of atrophy processes. Our hypothesis is that neuroendocrine stress induces post-translational changes of intracellular calcium handling proteins in skeletal muscle, leading to a dysfunctional calcium handling. Elucidating the mechanisms behind such perturbations would provide an important future target in the protection of muscle loss in the diseases stated above.

The third and last component is to identify biomarkers for complex conditions such as sarcopenia and muscle wasting in critical illness. In these studies our aim is to identify genetic markers that are associated with early onset and risk of development of severe muscle loss and dysfunction in aging, critical illness and in the progress of heart failure disease. Secondly we want to identify genetic markers that distinguish responders from non-responders to physical activity. In these studies, the overall goal is to be able to better identify high-risk subjects and those that may benefit from more aggressive preventive strategies.
