Document Summary
Innate ( nonspecific ) immunity - the term, innate immunity, refers to the basic resistance to disease that a species possesses - the first line of defense against infection. The characteristics of the innate immune response include the following: important. Responses are broad spectrum not specific. There is no memory or lasting protective immunity. There is a limited repertoire of recognition molecules. The innate immune response is a rapid immune response, whereas adaptive immunity takes time. The innate immune system comprises the cells and mechanisms that defend the host from infection by other organisms, in a nonspecific manner. This means that the cells of the innate system recognize, and respond to, pathogens in a generic way, but unlike the adaptive immune system, it does not confer long-lasting or protective immunity to the host. Innate immune systems provide immediate defense against infection, and are found in all classes of plant and animal life.
