1 A large and prolonged entry of external calcium is observed in dibutyryl cAMP treated cells; this may be due to direct regulation of calcium channels by the low affinity receptor, Fc gamma RII (whose expression is up-regulated in these cells), since the smaller and more transient entry observed in interferon-gamma treated cells, (where the high affinity receptor, Fc gamma RI, is up-regulated) argues against a common pathway of store-mediated calcium entry.
