Neuroinflammation, characterized by a complex interplay among innate and adaptive immune responses within the central nervous system (CNS), is crucial in responding to infections, injuries, and disease pathologies. However, the dysregulation of the neuroinflammatory response could significantly affect neurons in terms of function and structure, leading to profound health implications. Although tremendous progress has been made in understanding the relationship between neuroinflammatory processes and alterations in neuronal integrity, the specific implications concerning both structure and function have not been extensively covered, with the exception of perspectives on glial activation and neurodegeneration. Thus, this review aims to provide a comprehensive overview of the multifaceted interactions among neurons and key inflammatory players, exploring mechanisms through which inflammation influences neuronal functionality and structural integrity in the CNS. Further, it will discuss how these inflammatory mechanisms lead to impairment in neuronal functions and architecture and highlight the consequences caused by dysregulated neuronal functions, such as cognitive dysfunction and mood disorders. By integrating insights from recent research findings, this review will enhance our understanding of the neuroinflammatory landscape and set the stage for future interventions that could transform current approaches to preserve neuronal integrity and function in CNS-related inflammatory conditions.
神经炎症的特征是中枢神经系统(CNS)内固有和适应性免疫反应的复杂相互作用,对于应对感染、损伤和疾病病理至关重要。然而,神经炎症反应的失调可能会对神经元的功能和结构产生重大影响,导致严重的健康问题。尽管在理解神经炎症过程与神经元完整性改变之间的关系方面已经取得了巨大进展,但除了关于神经胶质激活和神经退行性变的观点外,关于结构和功能的具体影响尚未得到广泛涵盖。因此,本综述旨在全面概述神经元和关键炎症参与者之间的多方面相互作用,探讨炎症如何影响 CNS 中神经元的功能和结构完整性的机制。此外,还将讨论这些炎症机制如何导致神经元功能和结构的损伤,并强调失调神经元功能引起的后果,如认知功能障碍和情绪障碍。通过整合最近研究发现的见解,本综述将增强我们对神经炎症景观的理解,并为未来的干预措施奠定基础,这些干预措施可能会改变目前在 CNS 相关炎症情况下保护神经元完整性和功能的方法。
