In the past few years it has become increasingly clear that an understanding of the interaction between metabolism and immune function can provide an insight into cellular responses to challenges. Significant progress has been made in terms of how macrophages are metabolically re-programmed in response to inflammatory stimuli but, to date, little emphasis has been placed on evaluating equivalent changes in microglia. The need to make progress is driven by the fact that, while microglial activation and the cell's ability to adopt an inflammatory phenotype is necessary to fulfil the neuroprotective function of the cell, persistent activation of microglia and the associated neuroinflammation is at the heart of several neurodegenerative diseases. Understanding the metabolic changes that accompany microglial responses may broaden our perspective on how dysfunction might arise and be tempered. This review will evaluate the current literature that addresses the interplay between inflammation and metabolic reprogramming in microglia, reflecting on the parallels that exist with macrophages. It will consider the changes that take place with age including those that have been reported in neurons and astrocytes with the development of non-invasive imaging techniques, and reflect on the literature that is currently available relating to metabolic reprogramming of microglia with age and in neurodegeneration. Finally it will consider the possibility that manipulating microglial metabolism may provide a valuable approach to modulating neuroinflammation.

新兴的免疫代谢领域能否提供有关神经炎症的见解?

在过去的几年中,人们越来越清楚地了解新陈代谢和免疫功能之间的相互作用,可以洞悉细胞对挑战的反应。在巨噬细胞如何响应炎症刺激进行代谢重编程方面,已经取得了重大进展,但迄今为止,几乎没有重视评估小胶质细胞的等效变化。进步的需要是由以下事实驱动的:尽管小胶质细胞激活和细胞采取炎性表型的能力对于实现细胞的神经保护功能是必要的,但小胶质细胞的持续激活和相关的神经炎症是几种神经退行性疾病的核心。疾病。了解伴随小胶质细胞反应的代谢变化可能会拓宽我们对功能障碍可能如何发生和缓解的看法。这篇综述将评估有关炎症和小胶质细胞代谢重编程之间相互作用的最新文献,以反映巨噬细胞存在的相似之处。随着无创成像技术的发展,它将考虑随着年龄而发生的变化,包括在神经元和星形胶质细胞中已报道的变化,并反思与年龄相关的小胶质细胞的代谢重编程和神经退行性变的现有文献。 。最后,它将考虑操纵小胶质细胞代谢可能提供调节神经炎症的有价值方法的可能性。这篇综述将评估有关炎症和小胶质细胞代谢重编程之间相互作用的最新文献,以反映巨噬细胞存在的相似之处。随着无创成像技术的发展,它将考虑随着年龄而发生的变化,包括在神经元和星形胶质细胞中已报道的变化,并反思与年龄相关的小胶质细胞的代谢重编程和神经退行性变的现有文献。 。最后,它将考虑操纵小胶质细胞代谢可能提供调节神经炎症的有价值方法的可能性。这篇综述将评估有关炎症和小胶质细胞代谢重编程之间相互作用的最新文献,以反映巨噬细胞存在的相似之处。随着无创成像技术的发展,它将考虑随着年龄而发生的变化,包括在神经元和星形胶质细胞中已报道的变化,并反思与年龄相关的小胶质细胞的代谢重编程和神经退行性变的现有文献。 。最后,它将考虑操纵小胶质细胞代谢可能提供调节神经炎症的有价值方法的可能性。随着无创成像技术的发展,它将考虑随着年龄而发生的变化,包括在神经元和星形胶质细胞中已报道的变化,并反思与年龄相关的小胶质细胞的代谢重编程和神经退行性变的现有文献。 。最后,它将考虑操纵小胶质细胞代谢可能提供调节神经炎症的有价值方法的可能性。随着无创成像技术的发展,它将考虑随着年龄而发生的变化,包括在神经元和星形胶质细胞中已报道的变化,并反思有关与年龄相关的小胶质细胞的代谢重编程和神经退行性变的现有文献。 。最后,它将考虑操纵小胶质细胞代谢可能提供调节神经炎症的有价值方法的可能性。
