Harm KampingaParticipant CVON-DOSIS

Brief summary of research over the last five years

The focus of my research group concerns the regulation of protein quality control (PQC). My research group try to understand how heat shock proteins are regulated to protect cells against acute proteotoxic stress as well as chronic forms of stress, exploring the discovery that HSP families are large families that likely evolved to guarantee specificity and carry out multiple PQC functions. My laboratory generated a large, regulatable expression library of both human and Drosophila HSPs to test if and how they can modulate a variety (age-related) protein folding diseases including several neurodegenerative diseases and cardiac diseases (atrial fibrillation and cardiomyopathies). We have also embarked on studies on the mechanisms by which certain mutations in HSPs cause disease, including cardiac diseases, and how other components within the HSP network might compensate for the defects associated with these mutations. In the CVON project, our insights are exploited to uncover if and how stimulation of the PQC network may compensate for increased frailty of sarcomeric components associated with gene mutations that cause inherited cardiomyopathies.
