How Does the Innate Immune System Recognize Pathogens?
The innate immune system recognizes pathogens through pattern recognition receptors (PRRs). These receptors identify pathogen-associated molecular patterns (PAMPs) that are common among many types of pathogens. Examples of PRRs include Toll-like receptors (TLRs) and NOD-like receptors (NLRs). Once a PAMP is recognized, PRRs trigger a series of immune responses aimed at eliminating the pathogen.
