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 ...
B cells are a central component of the adaptive immune system, responsible for recognising pathogens and producing antibodies that neutralise infections. Their development, activation and ...
At the surface, the immune response to a flu virus is simple. Some cells recognize the pathogen and send a signal to the immune system, and immune cells produce a potentially lifesaving antibody ...
