However, details of the intervening steps, as researchers have learned in the past 65 years, are quite complex — certain cells carry the flu antigen to the immune system, specific immune cells respond ...

Even when immune memory cells form in the lung after influenza infection, insufficient dietary iron leaves them less able to mount a strong antiviral response, revealing how nutrition can shape ...
