42.3: Innate Immune Response - Pathogen Recognition

WebMany of the cells actively involved in the innate immune response are phagocytes that patrol blood and tissue searching for potentially threatening invaders. Once a pathogen is found, they use germline-encoded pattern recognition receptors (PRRs) on their cell membrane to distinguish the invaders’ molecules as foreign. WebAs discussed in Chapter 25, the innate immune responses to an infection are rapid. They depend on pattern recognition receptorsthat recognize patterns of pathogen-associated molecules (immunostimulants) that are not present in the host organism, including microbial DNA, lipids, and polysaccharides, and proteins that form bacterial flagella. imwrouteversionid
