collectins

col·lec·tins

(ko-lek'tinz),
A family of molecules that recognize and opsonize microbes during the preimmune response of a host; may activate the complement pathway.

collectins

(kō-lĕk′tĭnz)
Soluble, collagen-like proteins secreted into the blood of animals. They bind carbohydrate and fatty molecules on the surface of disease-causing microorganisms and help the body agglutinate, neutralize, or opsonize them so that they may be consumed and destroyed by white blood cells. Collectins are one component of the innate immune system.
