Fluoride activation of neutrophils: similarities to formylmethionyl-leucyl-phenylalanine.


Fluoride induced degranulation of both primary and specific granules from neutrophils pretreated with cytochalasin B. There was a similarity in the dependency on extracellular Ca2+ for fluoride- and for FMLP-stimulated O2- generation and degranulation. Pertussis toxin, but not cholera toxin, inhibited FMLP and fluoride activation of neutrophils, while… (More)
