"Innate Immune Systems Provide Strong Defense Against Infections"

Abstract

The innate immune system protects the host from infections. It includes cells that immediately recognize and respond to pathogens. The innate response of the immune system is not specific: it reacts in the same way to all pathogens it recognizes. Unlike the adaptive immune system, the innate system does not provide long-term immunity against specific infections. Innate immune systems provide immediate defense against infections.
