Diverging effects of chemotactic serum peptides and synthetic f-Met-Leu-Phe on neutrophil locomotion and adhesion

Diverging effects of chemotactic serum peptides and synthetic f-Met-Leu-Phe on neutrophil locomotion and adhesion

H U Keller et al. Immunology. 1981 Mar.

Abstract

The chemotactic serum peptide preparations CAT 1.6.1. and C5adesArg induced marked directional locomotion over a wide concentration range without significant effects on random locomotion and adhesion of human neutrophils in Gey's solution containing 2% HSA. In contrast, f-Met-Leu-Phe produced marked negative chemokinetic effects and its capacity to induce directional locomotion was more limited with respect to magnitude and concentration range. The negative chemokinetic effect of f-Met-Leu-Phe correlated closely with increased spreading and cell adhesion.
