The Ultimate Decoy: Protein M Helps Bacteria Misdirect Immune System

Researchers have discovered an unusual bacterial protein that attaches to virtually any antibody and prevents it from binding to its target. Protein M, as it is called, probably helps some bacteria evade the immune response and establish long-term infections. If follow-up studies confirm Protein M's ability to defeat the antibody response, it is likely to become a target of new antibacterial therapies. The protein's unique ability to bind generally to antibodies also should make it a valuable tool for research and drug development. read more
