PG - 37-43 AB - Human polymorphonuclear leukocytes (PMNL) which are a potential source of proteolytic enzymes and reactive oxidant species contribute to the development of pulmonary emphysema in cigarette smokers. We found that nicotine at concentrations that occur in smokers' plasma enhances human PMNL chemotactic response to zymosan-activated serum (ZAS) and n-formyl-methionyl-leucyl-phenylalanine (FMLP). Maximal increase in chemotactic migration was at nicotine concentration 1 mumol/l. Higher concentrations, above 0.1 mmol/l inhibited PMNL chemotactic response and spontaneous migration. Nicotine also enhanced PMNL influx to the place of inflammation developed in the mouse pleural cavity after injection of ZAS. The number of PMNL found in the pleural cavity was 1.9-fold higher (p less than 0.001, n = 5) when animals were pretreated with 0.15 mg of nicotine. However, this drug itself (concentrations of 0.1 mumol/l to 10 mmol/l) had weak chemotactic activity for PMNL. It seems that the stimulatory action of nicotine on PMNL chemotaxis may be partly responsible for increased PMNL numbers in the lower airways of cigarette smokers and following formation of the elastase/antielastase imbalance in lung tissue.
