Progression of influenza virus within the respiratory tract

We are exploring how influenza virus moves down the respiratory tract after infecting the nose. We have identified a component of mouse saliva that can halt the progression from the nose to the trachea and lungs and will determine how it binds to the virus to stop infection. We will also examine how human and highly lethal avian viruses move from the upper respiratory tract to other organs in the mouse and also in the ferret, which is a much better model for mimicking what happens in man.
