How do the innate and adaptive immune systems interact?
Innate can function on its own but is more effective when interacting with adaptive.Innate immune cells phagocytize items and "present" them to lymphocytes so that an adaptive immune response can be generated. Innate immune cells produce cytokine "messages" that influence lymphocyte responses. Once the adaptive immune system is up and running, the innate immune cells carry out much of their effector functions. Adaptive immune cells also produce cytokines which direct and increase, or decrease, the function of innate cells.
