Answer
Bruce Beutler's findings revealed how our bodies recognize and respond to pathogens. The Toll-like receptors (TLRs) are a family of receptors that recognize pathogen-associated molecular patterns (PAMPs) on pathogens. When TLRs bind to PAMPs, they trigger an immune response that helps the body fight off infection. Beutler's work has helped us to understand how the immune system works and has led to the development of new drugs to treat infection.
