摘要
目的 研究神经激肽B受体 (NK3)在小鼠中枢神经系统内的定位分布。 方法 免疫组织化学染色。 结果 在小鼠中枢神经系统的绝大部分区域 ,NK3受体样免疫反应产物位于胞体和树突上 ,少部分区域位于神经毡 (neuropil)内。大量NK3受体样免疫反应神经元出现于前嗅核、伏隔核、隔区、腹侧苍白球、苍白球、尾壳核、终纹床核、下丘脑前区、下丘脑结节区、下丘脑外侧区、穹隆周区、视上核、弓状核、乳头体、黑质、腹侧被盖区、红核后区、上丘和下丘、导水管周围灰质、孤束核、及延髓和脊髓背角浅层。大脑皮质的浅层、梨状皮质、背侧海马、杏仁核、脑干网状结构等核团内也含有一定数量的阳性神经元。在丘脑的中线核团和板内核、腹侧海马和脚间核等处 ,NK3受体免疫反应产物主要位于神经毡内。 结论 NK3受体广泛分布于小鼠中枢神经系统内 。
Objective To examine the localization of neurokinin B receptor (NK3)\|like immunoreactivity (\|LI) in the central nervous system of the mouse. Methods An immunohistochemcial staining method was used. Results NK3 receptor\|LI was localized in somatic and dendritic profiles in the most parts and in neuropil in a few regions of the mouse central nervous system. A large number of neurons with NK3\|LI was seen in the anterior olfactory nuclei, accumbens nucleus, septal area, ventral pallidum, pallidum, caudate putamen, nucleus of the stria terminalis, anterior hypothalamic area, tuber cincreum area, lateral hypothalamic area, perifornical nucleus, supraoptic nucleus, arcuate nucleus, mammillar nuclei, substatia nigra, ventral tegmental area, retrorubral area, superior and inferior colliculus, periaqueductal gray, nucleus of the solitary tract, and superficial layers of the medullary and spinal dorsal horns. The superfical layers of the cerebral cortex, piriform cortex, dorsal hippocampus, amygdal complex, reticular formation of the brainstem contained some neurons with NK3 receptor\|LI. In the ventral hippocampus, median and intralaminar nuclei of the thalamus and interpeduncular nuclei, NKR\|LI was localized in neuropil. Conclusion\ Neurons with NK3 receptor\|LI were widely distributed in the central nervous system. It may be involved in many physiological functions in the central nervous system of the mouse.\;[
