Cellular visualization of tissue prokallikrein in human neutrophils and myelocytes

1999

The vasoactive peptides bradykinin and kallidin (lysyl-bradykinin) have been implicated in diapedesis, a cellular process by which neutrophils migrate through endothelial cell gap junctions. The kinin peptides are released from their precursor moiety, kininogen, by the specific action of endoproteinases, the kallikreins. Kininogens have been demonstrated on the surface of neutrophils, and the presence of a competent processing enzyme such as tissue prokallikrein in neutrophils has been postulated, but firm evidence for this is still lacking. We have raised antibodies to a synthetic peptide that is a sequence copy of the activation segment of human TK and demonstrated that the anti-peptide a…
