  • Cell-attached recordings of macrophages were performed using the same solution in the pipette and in the extracellular medium at 37°C in the presence of 1 mM ATP at a holding potential of –40 mV

    Values are mean ± s.d. (n=5 independent experiments)

  • * P<0.05

  • Time opened/total time of recording

  • Mean time of a single channel in the open state
