🍀Infection Recognition Molecules 🟠In the innate immune system, this involves interaction between Pathogen Associated Molecular Patterns (PAMPs) and Pattern Recognition Receptors (PRRs). 🟠 In the adaptive immune system, this involves interaction between Major Histocompatibility Complexes (MHCs) and T cells. 🍀Pattern Recognition Receptors 🔵The innate immune system is rapid and non-specific, quickly phagocytosing foreign cells. It uses Pattern Recognition Receptors (PRRs) to recognise pathogens. 🔵Pattern Recognition Receptors are infection recognition receptors located on immune cells such as macrophages and dendritic cells. They bind to Pathogen Associated Molecular Patterns (PAMPs). 🔵A PAMP is a specific arrangement of carbohydrates, lipids and nucleic acids on the surface of a pathogen that signals to a phagocyte that a cell is foreign. 🔵Many different molecules can act as PAMPs, including peptidoglycans, e...
