The synaptology of neurotensin (NT)-, somatostatin (SS)- and vasoactive intestinal polypeptide (VIP)-immunoreactive neurons was studied in the central nucleus of the rat amygdala (CNA). Three types of axon terminals formed synaptic contacts with peptide-immunoreactive neurons in the CNA: Type A terminals containing many round or oval vesicles; Type B terminals containing many pleomorphic vesicles; and Type C terminals containing fewer, pleomorphic vesicles. Peptide-immunoreactive terminals were type A. All three types of terminals formed symmetrical axosomatic and asymmetrical axodendritic contacts. However, type B and peptide-immunoreactive terminals frequently formed symmetrical axodendritic synaptic contacts. VIP-immunoreactive terminals also formed asymmetrical axodendritic contacts. SS- and NT-immunoreactive terminals commonly formed symmetrical contacts on SS- and NT-immunoreactive cell bodies, respectively. VIP-immunoreactive axon terminals were postsynaptic to nonreactive terminals. Type B terminals appeared more frequently on VIP neurons than on NT or SS neurons.
在大鼠杏仁核中央核(CNA)中研究了神经降压素(NT)、生长抑素(SS)和血管活性肠多肽(VIP)免疫反应性神经元的突触学。三种类型的轴突终末与CNA中的肽免疫反应性神经元形成突触联系:A型终末含有许多圆形或椭圆形小泡;B型终末含有许多多形性小泡;C型终末含有较少的多形性小泡。肽免疫反应性终末为A型。所有三种类型的终末均形成对称的轴体和不对称的轴树突联系。然而,B型和肽免疫反应性终末经常形成对称的轴树突突触联系。VIP免疫反应性终末也形成不对称的轴树突联系。SS和NT免疫反应性终末通常分别在SS和NT免疫反应性细胞体上形成对称联系。VIP免疫反应性轴突终末位于无反应性终末的突触后。B型终末在VIP神经元上比在NT或SS神经元上出现得更频繁。
