Abstract
The innervation of the antennal heart of the cockroach Periplaneta americana was studied with immunocytochemical techniques on both the light and electron microscopic levels. The antennal heart is innervated by two efferent systems, both using one biogenic amine in combination with neuropeptides. In one, we found co-localization of serotonin with proctolin and allatostatin. These fibers most likely originate from paired neurons located in the suboesophageal ganglion. In the second system, we found octopamine co-localized with the short neuropeptide F. The source of this second system is dorsal unpaired median (DUM) neurons, also located in the suboesophageal ganglion. The possible effects of these neuromediators on different targets are discussed.
研究人员利用免疫细胞化学技术,在光镜和电子显微镜下对蜚蠊触角心脏的神经支配进行了研究。触角心脏由两个传出系统支配,两个系统都使用一种生物胺和神经肽。在其中一个系统中,我们发现了血清素与促泌素和动情素的共定位。这些纤维很可能来自食管下神经节的成对神经元。在第二个系统中,我们发现了章鱼胺与短神经肽 F 的共定位。第二个系统的来源是同样位于食管下神经节的背侧无配对正中神经元(DUM)。本文讨论了这些神经介质对不同靶点可能产生的影响。
期刊介绍:
The journal publishes regular articles and reviews in the areas of molecular, cell, and supracellular biology. In particular, the journal intends to provide a forum for publishing data that analyze the supracellular, integrative actions of gene products and their impact on the formation of tissue structure and function. Submission of papers with an emphasis on structure-function relationships as revealed by recombinant molecular technologies is especially encouraged. Areas of research with a long-standing tradition of publishing in Cell & Tissue Research include:
- neurobiology
- neuroendocrinology
- endocrinology
- reproductive biology
- skeletal and immune systems
- development
- stem cells
- muscle biology.
