The purpose of this study was to investigate the coexistence of gamma-aminobutyric acid (GABA) and leu-enkephalin in single neurons from the corpus striatum. Monolayer cell cultures, started from newborn rat corpus striatum, were grown in serum-free medium and examined using GABA autoradiography and leu-enkephalin immunocytochemistry in a double-label protocol. Examples of cells were found which were positive for one or the other neurotransmitter or for neither transmitter, but not for both. Furthermore, cells which appear similar by morphological criteria alone differed in transmitter specificity. We conclude that the two transmitters tested are not localized within single cells and that morphology alone is inadequate to identify functional cell classes in this area.
本研究的目的是调查纹状体单个神经元中γ-氨基丁酸(GABA)和亮氨酸脑啡肽的共存情况。从新生大鼠纹状体开始的单层细胞培养物在无血清培养基中生长,并采用双标记方案,通过GABA放射自显影和亮氨酸脑啡肽免疫细胞化学进行检测。发现了一些细胞实例,它们对一种或另一种神经递质呈阳性,或者对两种递质均呈阴性,但没有对两种递质都呈阳性的。此外,仅根据形态学标准看似相似的细胞在递质特异性方面存在差异。我们得出结论,所检测的两种递质并非定位于单个细胞内,仅靠形态学不足以识别该区域的功能性细胞类别。
