Our lab aims to dissect the molecular mechanisms underlying cardiac diseases to increase our knowledge on the organ functioning and to develop innovative and more effective approaches to treat the failing heart, such as nanodelivery of biologicals and personalized medicine.


The challenge

Many cardiac diseases are due to dysfunctions in the electrical signaling that coordinates heart cells contraction, such as heart rhythm disorders and heart failure, a chronic condition which is the clinical end-point of many cardiovascular disorders and one of the main causes of disability worldwide. We know already that calcium plays a key role in this electrical signaling and thus in regulating the pumping function of the heart. Since abnormal regulation of calcium is directly related to many heart diseases, a better understanding of the molecular mechanisms behind cardiac cells’ handling of calcium molecules will pave the way to new therapeutic solutions, that could take advantage of innovative precision-medicine and nanoparticles-based drug delivery systems.

Main research areas

Heart muscle contraction and calcium management

Characterizing the cross-talk between stressed cardiac and immunological cells has recently received attention. In recent years, we have gained a better understanding of the subcellular regulation of the L-Type Calcium Channel (LTCC) complex, which is a key trigging actor in the Calcium Induced Calcium Release mechanism in cardiac cells. We studied the altered intracellular LTCC trafficking in numerous acquired and genetically based cardiac diseases, as well as potential therapeutic interventions. A recent focus has been also dedicated to sepsis-induced cardiomyopathy, a recognized form of transient cardiac disorder occurring in patients affected by sepsis and associated to both excessive myocardial inflammation and calcium handling.

Biomimetic nanoparticle formulations for cardiac-specific drug delivery

The application of nanotechnology to medicine represents a revolutionary approach to successfully deliver therapeutics to specific cells and tissues in the body. Despite remarkable advances in the use of nanoparticles-driven delivery to fight cancer, there are very few studies reporting nanomedicine application in cardiovascular diseases (CVDs), even though it could help to overcome some of the limitations associated with current CVDs treatments. In our lab, we are studying innovative approaches to deliver therapeutics to the diseased heart via inhalation using biocompatible and biodegradable nanoparticles.
