細胞和分子神經(jīng)生理學

前言

人腦或神經(jīng)系統(tǒng)是我們已知的宇宙中最復(fù)雜的物質(zhì)結(jié)構(gòu)，神經(jīng)科學是探索腦的奧秘的科學，是21世紀迅猛發(fā)展的生命科學中最為突出的領(lǐng)域之一。過去的十多年中，分子生物學和計算機科學技術(shù)的快速發(fā)展，極大地推動了神經(jīng)科學的發(fā)展，人類基因組DNA序列的闡明及其對神經(jīng)科學的推動、腦功能成像技術(shù)研究人腦和心理活動的巨大進展便是最突出的代表。對許多神經(jīng)元活動的基本過程，神經(jīng)科學家已經(jīng)可以通過基因操作，在基因及其編碼的蛋白分子的結(jié)構(gòu)和功能水平上進行描述和分析，從而精細地研究其復(fù)雜的細胞膜上和胞內(nèi)信號的調(diào)控分子機制。腦功能成像技術(shù)使得過去只能停留在人腦這個“黑箱”外、對心理現(xiàn)象的腦機制進行各種猜測和假說的時代成為過去，人腦的認知和思維活動變得“看得見”了。神經(jīng)科學不僅吸引著各類神經(jīng)生物學家、化學家和物理學家，而且吸引分子生物學家、計算機科學家和心理學家紛紛加入其中，成為真正意義上的多種學科交叉的科學。

章節(jié)摘錄

插圖：Acetylcholinesterases are glycoproteins synthesizedin the soma and carried to the terminals via antero-grade axonal transport. They are inserted into thepresynaptic membrane and the basal lamina. They dis-play an important structural polymorphism （Figure6.12b）: they have a globular form （G） or an asymmetricform （A）. These different forms have distinct localiza-tions. Globular forms （G） are anchored in the pre- orpostsynaptic membrane （these are ectoenzymes） andare secreted as a soluble protein into the synaptic cleft.Asymmetric forms （A） are anchored in the basal lam-ina （Figure 6.12c）. The molecules of acetylcholine,released in the synaptic cleft when the neuromuscularjunction is activated, cross the basal lamina through itsloose stitches. But a part of the acetylcholine moleculesis also degraded before being fixed to postsynapticreceptors, by the acetylcholinesterase inserted in thebasal lamina. The other part is quickly degraded afterits fixation. Acetylcholinesterases hydrolyze acetyl-choline into acetic acid and choline. Choline is takenup by presynaptic terminals for the synthesis of newmolecules of acetylcholine. This degradation system ofacetylcholine is a very efficient system for inactivationof a neurotransmitter.6.3.3 Nicotinic receptors for acetylcholine are abundant in the crests of the folds in the postsynaptic membrane　 The plasma membrane of muscle cells, the sar-colemma, presents numerous folds in mammalian neu-romuscular junctions. By using a radioactive ligand for atype of acetylcholine nicotinic receptor, c-bungarotoxinlabelled with a radioactive isotope or a fluorescent mole-cule, it has been shown that the radioactive materialaccumulates predominantly in the crests of the folds inthe sarcolemma. Immunocytochemical techniques pro-duce similar results. Other studies have shown that theyare anchored to the underlying cytoskeleton （see thefollowing section）.　 The nicotinic receptor is a transmembrane glycopro-tein comprising four homologous subunits assembledinto a heterologous 2B8 pentamer. It is a receptorchannel permeable to cations whose activation resultsin the net entry of positively charged ions and in depolar-ization of the postsynaptic membrane. The structureand functional characteristics of the muscular icotinicreceptors are given in Chapter 8.6.3.4 Mechanisms involved in the accumulation of postsynaptic receptorsin the folds of the postsynaptic muscular membrane　 The acetylcholine nicotinic receptors are, in theadult neuromuscular junction, present in high density（about 10,000 molecules per itm） in the postsynapticregions and occur in a much lower density in thenonsynaptic membrane （extrajunctional membrane）.Under the nerve terminal, the muscle cell is free of themyofimanents actin and myosin. At this level, four toeight cell nuclei are found, the fundamental nuclei（Ranvier 1875）. The myonuclei located outside the post-synaptic region （extrasynaptic） are the sarcoplasmicnuclei. The formation of this well organized subsynapticdomain - which concerns not only the nicotinic recep-tors but also the Golgi apparatus and the cytoskeleton（it also comprises the organization of the basal laminaand the distribution of the asymmetric form of acetyl-cholinesterase in the synaptic cleft） - occurs in numer-ous steps during maturation of the neuromuscularjunction （Figure 6.13a）:　There is an increase in the number of nicotinicreceptors （1 and 2） during fusion of the myoblasts to form myotubes, owing to the neosynthesis of these receptors. They have an even distribution over the membrane surface. This phenomenon is independent of the neuromuscular activity since it is not affected by the injection in ovo of nicotinic antagonists such as curare.~　There is formation of aggregates of nicotinic receptors under the nerve terminal （3-5） and disappearance of extrajunctional receptors （5）.
