Innate lymphocytes, including microglial cells, astrocytes, and oligodendrocytes, play a crucial role in initiating neuroinflammatory reactions inside the central nervous system (CNS). The prime focus of this paper is on the involvement and interplay of neurons and glial cells in neurological disorders such as Alzheimer's Disease (AD), Autism Spectrum Disorder (ASD), epilepsy, and multiple sclerosis (MS). In this review, we explore the specific contributions of microglia and astrocytes and analyzes multiple pathways implicated in neuroinflammation and disturbances in excitatory and inhibitory processes. Firstly, we elucidate the mechanisms through which toxic protein accumulation in AD results in synaptic dysfunction and deregulation of the immune system and examines the roles of microglia, astrocytes, and hereditary factors in the pathogenesis of the disease. Secondly, we focus on ASD and the involvement of glial cells in the development of the nervous system and the formation of connections between neurons and investigates the genetic connections associated with these processes. Lastly, we also address the participation of glial cells in epilepsy and MS, providing insights into their pivotal functions in both conditions. We also tried to give an overview of seven different pathways like toll-like receptor signalling pathway, MyD88-dependent and independent pathway, etc and its relevance in the context with these neurological disorders. In this review, we also explore the role of activated glial cells in AD, ASD, epilepsy, and MS which lead to neuroinflammation. Even we focus on excitatory and inhibitory imbalance in all four neurological disorders as imbalance affect the proper functioning of neuronal circuits. Finally, this review concludes that there is necessity for additional investigation on glial cells and their involvement in neurological illnesses.
先天淋巴细胞,包括小胶质细胞、星形胶质细胞和少突胶质细胞,在中枢神经系统(CNS)内引发神经炎症反应中起着至关重要的作用。本文的主要重点是神经元和神经胶质细胞在神经退行性疾病(如阿尔茨海默病(AD)、自闭症谱系障碍(ASD)、癫痫和多发性硬化症(MS))中的作用和相互作用。在这篇综述中,我们探讨了小胶质细胞和星形胶质细胞的具体贡献,并分析了神经炎症和兴奋性及抑制性过程紊乱中涉及的多种途径。首先,我们阐明了 AD 中有毒蛋白积累导致突触功能障碍和免疫系统失调的机制,并研究了小胶质细胞、星形胶质细胞和遗传因素在疾病发病机制中的作用。其次,我们专注于 ASD 以及神经胶质细胞在神经系统发育和神经元之间连接形成中的作用,并研究了与这些过程相关的遗传联系。最后,我们还讨论了神经胶质细胞在癫痫和多发性硬化症中的参与,提供了它们在这两种疾病中的关键作用的见解。我们还尝试概述了包括 Toll 样受体信号通路、MyD88 依赖性和非依赖性通路等在内的七种不同途径及其与这些神经退行性疾病相关的相关性。在这篇综述中,我们还探讨了激活的神经胶质细胞在 AD、ASD、癫痫和多发性硬化症中的作用,这些作用导致了神经炎症。我们还关注了这四种神经退行性疾病中的兴奋性和抑制性失衡,因为失衡会影响神经元回路的正常功能。最后,本综述得出结论,有必要进一步研究神经胶质细胞及其在神经疾病中的作用。
