Research Interests

The Center for Research on Cardiac Intermediate Filaments was funded within the division of Cardiology at Johns Hopkins to foster collaboration projects aimed at elucidating the pathophysiological role of this understudied component of the cytoskeleton in cardiovascular disease. Desmin is the main protein component of the cardiac intermediate filaments. The induction of desmin at the translational and post-translational level (e.g. cleavage) as well as its misfolding are hallmarks of cardiac dysfunction. The ultrastructural implications of a cytoskeletal alteration in the heart are straightforward. In addition, protein misfolding is emerging as a major contributor to the development of cardiovascular disease. Our research interests revolve around the role of desmin post-translational modifications, determining the relative contribution of desmin loss of and gain of toxic function and how to target those pharmacologically to prevent cardiac dysfunction.

Technologies offered to other EuroCellNet participants

We use a combination of cell biology (confocal microscopy, single-site mutagenesis, etc. ), advanced biochemistry (mass spectrometry) and experimental and clinical models of cardiovascular disease spanning from isolated cells, invertebrates, vertebrates and human tissue.

Technologies sought from other EuroCellNet participants

Intermediate filaments biology, live cell imaging, super-resolution microscopy
