The importance of chloride ions in cell physiology has not been fully recognized until recently, in spite of the fact that chloride (Cl-), together with bicarbonate, is the most abundant free anion in animal cells, and performs or determines fundamental biological functions in all tissues. For many years it was thought that Cl- was distributed in thermodynamic equilibrium across the plasma membrane of most cells. Research carried out during the last couple of decades has led to a dramatic change in this simplistic view. We now know that most animal cells, neurons included, exhibit a non-equilibrium distribution of Cl- across their plasma membranes. Over the last 10 to 15 years, with the growth of molecular biology and the advent of new optical methods, an enormous amount of exciting new information has become available on the molecular structure and function of Cl- channels and carriers. In nerve cells, Cl- channels and carriers play key functional roles in GABA- and glycine-mediated synaptic inhibition, neuronal growth and development, extracellular potassium scavenging, sensory-transduction, neurotransmitter uptake and cell volume control. Disruption of Cl- homeostasis in neurons underlies pathological conditions such as epilepsy, deafness, imbalance, brain edema and ischemia, pain and neurogenic inflammation. This book is about how chloride ions are regulated and how they cross the plasma membrane of neurons. It spans from molecular structure and function of carriers and channels involved in Cl- transport to their role in various diseases.
* The first comprehensive book on the structure, molecular biology, cell physiology, and role in diseases of chloride transporters / channels in the nervous system in almost 20 years
* Chloride is the most abundant free anion in animal cells. THis book summarizes and integrates for the first time the important research of the past two decades that has shown that Cl- channels and carriers play key functional roles in GABA- and glycine-mediated synaptic inhibition, neuronal growth and development, extracellular potassium scavenging, sensory-transduction, neurotransmitter uptake and cell volume control.
* The first book that systematically discusses the result of disruption of Cl- homeostasis in neurons which underlies pathological conditions such as epilepsy, deafness, imbalance, brain edema and ischemia, pain and neurogenic inflammation.
* Spanning topics from molecular structure and function of carriers and channels involved in Cl- transport to their role in various diseases.
* Involves all of the leading researchers in the field.
* INcludes an extensive introductory section that covers basic thermodynamic and kinetics aspects of Cl- transport, as well as current methods for studying Cl- regulation, spanning from fluorescent dyes in single cells to knock-out models to make the book available for a growing population of graduate students and postdocs entering the field.

我对这本书的整体印象是,它极其强调功能与结构之间的耦合关系,并且毫不避讳地探讨了许多尚未完全解决的科学难题。不同于某些只关注“是什么”的综述性著作,此书更侧重于“为什么”和“如何”——为什么特定的氯离子通道突变会导致严重的神经退行性疾病,以及这些转运机制是如何在发育过程中被精确调控的。书中对病理生理学的讨论尤为深刻,通过详尽的案例分析,展示了微小的离子流失衡如何引发癫痫、疼痛或神经精神障碍的连锁反应。阅读过程中,我常常需要停下来,反复对照图表,试图完全理解那些复杂的分子动力学描述。这种阅读体验是挑战性的,但收获是巨大的。它迫使我重新审视过去习以为常的神经元兴奋性概念,认识到氯离子梯度远非静止的背景参数,而是活跃的、时刻参与信息编码和记忆巩固的动态参与者。对于临床神经科学家而言,这本书无疑是一份及时的、基于机制的知识更新。
评分这本书的叙事风格是极其严谨且具有高度学术性的,它精准地把握住了氯离子生物学研究的前沿脉搏。从分子层面解析氯离子通道的晶体结构,到细胞层面探讨其与GABA受体或NMDA受体的互作动力学,再到器官层面分析其对整个皮层网络同步性的影响,这种跨尺度的整合能力是本书的一大亮点。我特别欣赏作者在处理“争议性”研究结果时的审慎态度,他们不会武断地下结论,而是公正地呈现不同实验体系下的矛盾数据,引导读者独立思考。此外,书中对新技术(如光遗传学、高通量测序)在揭示氯离子转运新机制中的应用进行了相当篇幅的介绍,这使得内容具有极强的时效性。对于研究生而言,这本书提供的不仅仅是知识,更是一种严谨的科学研究范式——即如何通过多角度的验证来构建一个可靠的生物学模型。它不是轻松的读物,而是需要投入大量精力的智力投资。
评分这部厚重的专著初窥门径,便觉其内容之广博与精深令人侧目。作者似乎并未满足于对基本生理机制的罗列,而是深入挖掘了氯离子转运体和离子通道在神经系统复杂功能网络中的关键作用。书中对跨膜电位调控、兴奋性/抑制性神经传递平衡的微妙机制进行了细致入微的剖析,读起来如同在迷宫中寻觅正确的路径,每一步都充满了对生物电生理学新认知的惊喜。尤其值得称道的是,它不仅仅停留在理论层面,大量的实验数据和前沿的研究成果被巧妙地融入叙述之中,使得抽象的概念变得具体可感。例如,对于特定转运蛋白亚型的空间分布及其在不同神经元亚群中的功能特异性,阐述得淋漓尽致。我感觉这不仅仅是一本教科书,更像是一份详尽的、经过时间沉淀的“研究工具箱”,为那些希望在神经科学领域深耕的学者提供了坚实的理论基石和广阔的思考空间。它迫使读者跳出传统的电生理学框架,以更动态、更立体的视角去审视氯离子在维持中枢和外周神经系统稳态中的核心地位。
评分这本书的编排结构显示出作者对该领域历史脉络的深刻理解。它并非简单地堆砌最新发现,而是巧妙地将历史上的经典实验发现与当前的分子生物学突破穿插叙述。这种“纵向发展”的叙事方式,让读者能够清晰地看到科学认知是如何一步步修正和深化的。例如,对囊性纤维化跨膜电导调节因子(CFTR)在非典型部位(如突触前膜)功能的研究,被置于其经典肺部病理学的背景之下进行讨论,极大地拓宽了我们对CFTR在神经系统中潜在角色的想象空间。对于寻求跨学科知识的读者来说,这本书提供了极佳的桥梁,它既能满足分子生物学家的精确度要求,又能满足系统神经科学家的功能性需求。总体而言,这是一部结构严谨、信息密度极高、且极具启发性的学术巨著,它无疑将成为未来十年内该领域研究人员案头的必备参考书。
评分阅读体验上,这本书给我带来了一种“抽丝剥茧”的畅快感,尤其是在氯离子平衡与细胞体积调节之间的关联描述部分。作者似乎深谙如何将复杂的生化信号通路转化为清晰的逻辑流程图。不同于许多依赖于大量抽象定义的书籍,此书的每一章都仿佛在讲述一个精心构建的故事,主角是那些看似不起眼的氯离子通道蛋白。他们如何响应pH值、磷酸化状态,甚至细胞内钙离子浓度的微小变化,进而影响神经元的“开”与“关”。书中对肾脏和中枢神经系统氯离子转运体的比较分析也极具洞察力,展示了跨组织的功能保守性与适应性进化。我感觉,这本书成功地将过去分散在各个专业期刊中的碎片化信息系统地整合起来,形成了一个关于氯离子生物学的完整生态系统视图。这对于理解中风后神经元损伤或慢性疼痛信号的维持机制,提供了无可替代的深度视角。
