Neuroinflammation is an inflammatory response occurring within the central nervous system (CNS). The process is marked by the production of pro-inflammatory cytokines, chemokines, small-molecule messengers, and reactive oxygen species. Microglia and astrocytes are primarily involved in this process, while endothelial cells and infiltrating blood cells contribute to neuroinflammation when the blood-brain barrier (BBB) is damaged. Neuroinflammation is increasingly recognized as a pathological hallmark of several neurological diseases, including amyotrophic lateral sclerosis (ALS), and is closely linked to neurodegeneration, another key feature of ALS. In fact, neurodegeneration is a pathological trigger for inflammation, and neuroinflammation, in turn, contributes to motor neuron (MN) degeneration through the induction of synaptic dysfunction, neuronal death, and inhibition of neurogenesis. Importantly, resolution of acute inflammation is crucial for avoiding chronic inflammation and tissue destruction. Inflammatory processes are mediated by soluble factors known as cytokines, which are involved in both promoting and inhibiting inflammation. Cytokines with anti-inflammatory properties may exert protective roles in neuroinflammatory diseases, including ALS. In particular, interleukin (IL)-10, transforming growth factor (TGF)-β, IL-4, IL-13, and IL-9 have been shown to exert an anti-inflammatory role in the CNS. Other recently emerging immune regulatory cytokines in the CNS include IL-35, IL-25, IL-37, and IL-27. This review describes the current understanding of neuroinflammation in ALS and highlights recent advances in the role of anti-inflammatory cytokines within CNS with a particular focus on their potential therapeutic applications in ALS. Furthermore, we discuss current therapeutic strategies aimed at enhancing the anti-inflammatory response to modulate neuroinflammation in this disease.
神经炎症是发生在中枢神经系统(CNS)内的一种炎症反应。该过程的特征是促炎细胞因子、趋化因子、小分子信使和活性氧的产生。小胶质细胞和星形胶质细胞主要参与此过程,而当血脑屏障(BBB)受损时,内皮细胞和浸润的血细胞也会促成神经炎症。神经炎症越来越被认为是包括肌萎缩侧索硬化症(ALS)在内的几种神经疾病的病理标志,并且与ALS的另一个关键特征——神经退行性变密切相关。事实上,神经退行性变是炎症的病理触发因素,而神经炎症反过来又通过诱导突触功能障碍、神经元死亡和抑制神经发生,促成运动神经元(MN)的退化。重要的是,急性炎症的消退对于避免慢性炎症和组织破坏至关重要。炎症过程由称为细胞因子的可溶性因子介导,这些因子既参与促进炎症,也参与抑制炎症。具有抗炎特性的细胞因子可能在包括ALS在内的神经炎症性疾病中发挥保护作用。特别是,白细胞介素(IL)-10、转化生长因子(TGF)-β、IL-4、IL-13和IL-9已被证明在中枢神经系统中发挥抗炎作用。中枢神经系统中其他最近出现的免疫调节细胞因子包括IL-35、IL-25、IL-37和IL-27。本综述描述了目前对ALS中神经炎症的理解,并强调了抗炎细胞因子在中枢神经系统中的作用的最新进展,特别关注它们在ALS中的潜在治疗应用。此外,我们讨论了目前旨在增强抗炎反应以调节该疾病中神经炎症的治疗策略。
