anaphylatoxin
This term is used exclusively within medical, immunological, and biochemical contexts. It describes a specific class of peptides that act as potent triggers for systemic inflammatory reactions. Because it refers to a precise molecular mechanism, it is never used in casual conversation or general descriptions of allergies.
As a technical term for a specific biological agent, it follows standard English noun pluralization. It is typically used in the singular when discussing the general mechanism of action or in the plural when referring to the various types of fragments, such as C3a and C5a.
Meanings
A potent inflammatory peptide, typically a fragment of the complement system (such as C3a or C5a), that triggers the release of histamine from mast cells and basophils, thereby inducing an anaphylactic response.
The administration of an anaphylatoxin can lead to rapid vasodilation and increased vascular permeability.
