Abstract

In HL-60 cells, extracellular A TP increases intracellular $Ca^{2＋}$ ([Ca$^{2＋}$]$_{i}$) in a concentration-dependent manner with the maximal response occurring around 10 $\mu$M. However, above the maximal responsive concentration ATP elicits different patterns of $Ca^{2＋}$ signaling.(omitted)d)
