The development and physiological and pathophysiological functions of resident macrophages and glial cells

Adv Immunol. 2021;151:1-47. doi: 10.1016/bs.ai.2021.08.001. Epub 2021 Oct 4.ABSTRACTIn the past, brain function and the onset and progression of neurological diseases have been studied in a neuron-centric manner. However, in recent years the focus of many neuroscientists has shifted to other cell types that promote neurodevelopment and contribute to the functionality of neuronal networks in health and disease. Particularly microglia and astrocytes have been implicated in actively contributing to and controlling neuronal development, neuroinflammation, and neurodegeneration. Here, we summarize the development of brain-resident macrophages and astrocytes and their core functions in the developing brain. We discuss their contribution and intercellular crosstalk during tissue homeostasis and pathophysiology. We argue that in-depth knowledge of non-neuronal cells in the brain could provide novel therapeutic targets to reverse or contain neurological diseases.PMID:34656287 | DOI:10.1016/bs.ai.2021.08.001
