innate immunity


Also found in: Dictionary, Thesaurus, Legal, Encyclopedia, Wikipedia.

in·nate im·mu·ni·ty

resistance manifested by a species (or by races, families, and individuals in a species) that has not been immunized (sensitized, allergized) by previous infection or vaccination; much of it results from body mechanisms that are poorly understood but differ from those responsible for the altered reactivity associated with the specific nature of acquired immunity; in general, innate immunity is nonspecific and is not stimulated by specific antigens.

Synonym(s): natural immunity, nonspecific immunity

innate immunity

The nonspecific first line of defence against foreign pathogens that is an integral facet of the immune response, which is mediated by dendritic cells (DCs), natural killer (NK) cells, macrophages, neutrophils, basophils, eosinophils and mast cells. Macrophages and mast cells serve as sentinels stationed in tissues, which continuously monitor their microenvironment for signs of distress.
