Bacteriotropins
DefinitionThis section has been translated automatically.
Opsonins are serum components in humans and animals that attach themselves to foreign antigenic substances, especially microorganisms, so that they can be absorbed and eliminated by phagocytes (macrophages) (see also opsonation). The most important opsonin is the complement factor C3b, which binds to the CR1 receptor and thereby initiates phagocytosis of the allergen.
