TLRs (Toll-like receptors) are phagocyte receptors that recognize and bind to Pathogen-Associated Molecular Patterns (PAMPs) on the surface of pathogens. This recognition triggers a cascade of events that leads to the activation of the immune system to eliminate the invading pathogen. TLRs are essential for the detection of various types of pathogens, including bacteria, viruses, fungi, and parasites.
