Influenza mutates regularly to avoid neutralizing antibodies and immune responses that target more conserved areas are needed to combat new flu pandemics. Influenza ADCC has been a neglected area of research in recent decades. We adapted and refined our HIV ADCC assays to study Influenza. We found there is a remarkable degree of cross-reactivity in Influenza ADCC immunity. We found that influenza ADCC can play a role in reducing the severity of the 2009 Swine Flu epidemic in both humans and monkeys. 147,148 * The work opens up a whole new field of Flu immunity. We are now studying how Flu-specific ADCC and antibody-dependent phagocytosis can be induced by vaccination204,240,242 * and lead to protective immunity. Recent work shows ADCC is important in controlling H7N9 avian influenza 234 * and may be important in passive transfer studies258 *.
