using the micropore filter approach , the authors studied the chemoattracting properties of tachykinins , including substance p ( sp ) , neurokinin a ( nka ) and neurokinin b ( nkb ) , and that of calcitonin gene-related peptide ( cgrp ) for human pmnl in vitro and now show that sp in near nanomolar concentrations stimulates locomotion of human pmnl .
