Basophil

VA: Tomokazu Sugita/DC Douglas

A type of White Blood Cell. Said to comprise less than 1% of all White Blood Cells. When a Basophil encounters a specific antigen, it releases histamines and the like, thereby triggering an allergic reaction. It creates a substance that will draw Neutrophils and Eosinophils to the affected area.
Basophils are thought to have immunity-related functions as well, but this has yet to be sufficiently determined.
