Study identifies enzyme that plays crucial role in resistance to influenza
PostedJanuary 16, 2014
McGill researchers, led by Dr. Maya Saleh of the Department of Medicine, have identified an enzyme, cIAP2 that helps the lungs protect themselves from the flu by giving them the ability to resist tissue damage. “It’s a discovery that offers exciting new avenues for controlling influenza, since until now attempts to target the virus itself have proven challenging, especially in the face of emerging new strains of the virus,” says Saleh, who is also a researcher at the Research Institute of the McGill University Health Centre (RI-MUHC). “The results from our study now suggest that one effective way of countering influenza infections may instead be offered by enhancing the body’s resistance to the virus.”
Like many other battles, fighting the flu is a combination of both control and defence. On the one hand, on the control end of the process, our immune system comes into play to prevent the virus from replicating inside our cells, and attacking with increasing strength. At the same time, on the defensive side, our bodies need to actively resist the destruction and harmful cell death that is caused by the virus.
