Calpains, key cellular enzymes for fighting influenza

Why not fight the influenza virus by blocking the cellular machinery it uses for replication? Researchers from Inserm (Unit 1100, “Respiratory Pathologies: Proteolysis and Aerosoltherapy”), Institut Pasteur and the HKU-Pasteur Research Pole in Hong Kong tested this hypothesis by specifically targeting the calpains, proteases involved in inflammatory mechanisms. Their results, obtained in animals, show that inhibiting these enzymes can not only reduce the symptoms of the disease, but also prevent infection by seasonal or pandemic influenza viruses.

Results of this study were published in the American Journal of Physiology, Lung Cellular and Molecular Physiology in January 2016.
