Abstract

Neuroblastoma x glioma NG108-15 hybrid cells exposed to N6, O2'-dibutyryladenosine 3':5'-cyclic monophosphate for several days release [3H]acetylcholine in response to serotonin, prostaglandin F2alpha, KCl, or veratridine. NG108-15 cells grown in the absence of dibutyrul cyclic AMP do not respond to an excitatory stimulus by releasing [3H]acetylcholine but can be shifted to a responsive state by treatment with dibutyryl cyclic AMP. Thus, the reactions that are required for acetylcholine release can be regulated in NG108-15 cells, thereby regulating the ability of cells to form synapses and the efficiency of synaptic communication.

摘要

暴露于N6, O2'-二丁酰腺苷3':5'-环一磷酸数天的神经母细胞瘤x胶质瘤NG108-15杂交细胞,会对血清素、前列腺素F2α、氯化钾或藜芦碱作出反应而释放[3H]乙酰胆碱。在没有二丁酰环磷腺苷的情况下生长的NG108-15细胞,不会通过释放[3H]乙酰胆碱对兴奋性刺激作出反应,但可以通过用二丁酰环磷腺苷处理而转变为反应状态。因此,NG108-15细胞中乙酰胆碱释放所需的反应可以被调节,从而调节细胞形成突触的能力和突触通讯的效率。
