Abstract

The question of how changes in chemoattractant concentration translate into the chemotactic response of immune cells serves as a paradigm for the quantitative understanding of how cells perceive and process temporal and spatial information. Here, using a microfluidic approach, we analyzed the migration of neutrophil-like HL-60 cells to a traveling wave of the chemoattractants N-formyl-methionyl-leucyl-phenylalanine (fMLP) and leukotriene B4 (LTB4). We found that under a pulsatile wave that travels at a speed of 95 and 170 µm/min, cells move forward in the front of the wave but slow down and randomly orient at the back due to temporal decrease in the attractant concentration. Under a slower wave, cells reorient and migrate at the back of the wave; thus, cell displacement is canceled out or even becomes negative as cells chase the receding wave. Fluorescence resonance energy transfer (FRET)-based analysis indicated that these patterns of movement correlated well with spatiotemporal changes in Cdc42 activity. Furthermore, pharmacological perturbations showed that (re)orientation in front and back of the wave had different susceptibility to Cdc42 and ROCK inhibition. These results suggest that pulsatile attractant waves may recruit or disperse neutrophils, depending on their speed and degree of cell polarization.
