Abstract
Within about 10 seconds after stimulation of Dictyostelium discoideum cells with cyclic AMP an increased rate of 45Ca influx was observed. Part of the cellular calcium reappeared in the extra-cellular medium between 1 and 3 minutes after stimulation. No effect of 5'AMP on calcium distribution was found. The transient calcium influx is discussed in connection with chemotaxis and other cyclic-AMP induced responses.
摘要
在用环磷酸腺苷刺激盘基网柄菌细胞后约10秒内，观察到45Ca内流速率增加。刺激后1至3分钟内，部分细胞内钙重新出现在细胞外培养基中。未发现5'AMP对钙分布有影响。结合趋化性和其他环磷酸腺苷诱导的反应对瞬时钙内流进行了讨论。
