This lesson is intended to cover the concepts of innate immunity. The immune system ‘sees’ the world as self and non-self. The innate immune system does this via receptors that have evolved to recognize relatively conserved structures in microbes. Once a non-self entity is recognized, innate immune cells respond by phagocytosing the threat and sounding the alarm (cytokines and chemotaxis). Most infections are stopped by innate immune responses.
