You have three to five pounds of bacteria
living in and on your body right now. That's some 38 trillion bacteria,
researchers estimate. Your immune system has to manage all of them,
sorting out the good from the bad bugs.
"We have an amazing immune system to keep that all in check, and then to deal with pathogenic bacteria,"
says Catherine Leimkuhler Grimes, assistant professor of chemistry and
biochemistry at the University of Delaware. "It's fantastic when the
system works, but also horrific when it doesn't."
When a beneficial bacterium is mistakenly identified as a harmful one, the immune system's attack can trigger chronic inflammatory diseases
such as asthma, Crohn's disease and other disorders. Why this
misidentification occurs is a mystery, but Grimes and her research team
at the University of Delaware have invented a promising new method to
literally help illuminate what happens. The advance is published in Nature Communications.
