Evolution In Action: Our Antibodies Take 'Evolutionary Leaps' To Fight Microbes

With cold and flu season in full swing, the fact that viruses and bacteria rapidly evolve is apparent with every sneeze, sniffle, and cough. A new report explains for the first time how humans keep up with microbes by rearranging the genes that make antibodies to foreign invaders. This research fills a significant gap in our understanding of how the immune system helps us survive.

"We've known for a long time that our antibody-forming system adapts itself to every microbe we encounter," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal, "but what we didn't understand fully is exactly how this happens. Now that we know, we can begin to find ways to manipulate this process so illnesses can be prevented or made significantly less dangerous."
