WebAug 21, 2024 · When they detect a pathogen and phagocytose (engulf) it, they then seek out T cells to present them to, connecting the innate and adaptive immune response. If the T cell recognizes the antigen the adaptive immune response is initiated. *Dendritic cells have many projections or arms that they use to sample cells with. 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.
