Scientists watch an immune system fight the flu in real time
To date, biologists have typically had to study the progress of a virus through indirect means, such as studying the antibodies -- actually tracking the viruses themselves has been difficult. However, researchers say they've found a way to follow the progress of a virus in real time. By using multiphoton microscopy in tandem with a laser and fluorescence, the team monitored influenza virus in a mouse's trachea (where the transluency made imaging possible) through the infection and immune system response.
