Shedding light on how body fends off bacteria

To invade organisms such as humans, bacteria make use of a protein called flagellin, part of a tail-like appendage that helps the bacteria move about. Now, for the first time, a team led by scientists at The Scripps Research Institute and Sanford-Burnham Medical Research Institute has determined the 3D structure of the interaction between this critical bacterial protein and an immune molecule called TLR5, shedding light on how the body protects itself from such foreign invaders.
