Electron microscopic study of intraocular grafts of the septal and hippocampal nervous tissue revealed intensive transport and metabolic interactions between various types of the cells. High level of transport exists between the recipient's blood and intraocular fluid, on the one hand, and the graft, on the other one; the abundance of pinocytotic vesicles in the endothelium, pericytes and the glial end-feet of the capillaries, and the presence of microvilli and cilia on the graft limiting glia. Signs of active communications between interstitial glial cells, as well as between gliocytes and neurons, such as pinocytosis and gap junctions were observed. Similar interactions exist between various parts of nerve cells. Besides, there is an evidence of microphagocytic interactions, particularly between pre- and postsynaptic elements, as shown by the presence of so-called spinules. An unusual fact was observed of internalization of cytoplasmic fragments of the degenerating neuron by contacting synaptic boutons. It is suggested that the high level of transport and metabolic processes may reflect adaptive and compensatory processes in the nervous tissue developing under strict limitations of the neural and neurotrophic influences.
对鼻中隔和海马神经组织眼内移植的电子显微镜研究显示，不同类型细胞之间存在活跃的运输和代谢相互作用。一方面，受体血液与眼内液之间，另一方面与移植物之间存在高水平的运输；内皮细胞、周细胞和毛细血管的神经胶质终足中存在丰富的胞饮小泡，移植物限制神经胶质上存在微绒毛和纤毛。观察到间质神经胶质细胞之间以及神经胶质细胞与神经元之间存在活跃通讯的迹象，如胞饮作用和缝隙连接。神经细胞各部分之间也存在类似的相互作用。此外，有证据表明存在微吞噬相互作用，特别是在突触前和突触后成分之间，如所谓的棘状突起所示。观察到一个不寻常的现象，即退化神经元的细胞质片段被接触的突触小体内化。有人认为，高水平的运输和代谢过程可能反映了在神经和神经营养影响的严格限制下发育的神经组织中的适应性和补偿性过程。
