In health, microglia are highly motile cells that survey their surrounding environment to maintain homeostasis [3], promote synaptogenesis, and regulate the integrity of the blood–brain barrier [4,5]. However, microglia become activated and proliferate after acute brain injury or in chronic ...
Microglia maintain existing myelinWe next asked whether these changes in myelin growth and integrity reflect disruption of myelin formation or myelin maintenance. To that end, we depleted microglia in mice when developmental myelination is complete (2 months of age onwards) by providing the CSF1R ...
Microglia, the resident macrophages of the central nervous system (CNS), utilize their specific receptor repertoire to monitor the microenvironment dynamically in the brain.1Microglia phagocytose misfolded proteins, cellular debris, and dying cells to maintain homeostasis.2Additionally, microglia could moni...

In healthy status, microglia maintain a homeostatic state, characterized by a unique transcriptional profile that includes genes like purinergic receptor P2RY12 and C-X3-C motif chemokine receptor 1 (CX3CR1). These cells perform routine surveillance of the brain environment, phagocytosing apoptotic ...
More recent evidence indicates that microglia are dispensable for OPC maturation and differentiation, nonetheless they are critical to maintain myelin health by preventing demyelination and hypermyelination [10], confirming microglia’s role in preserving myelin integrity that is altered in aging. ...
Microglia arise from yolk-sac-derived precursors and maintain their population via local self-renewal in the healthy central nervous system (CNS) [17]. In mice, microglia emerge from early erythromyeloid precursor cells (EMPs) in the extraembryonic yolk sac at embryonic day 7.5 (E7.5), subsequen...
Microglia are integral to the brain’s innate immune system and play a crucial role in its structural remodeling and function. They maintain neuronal health and integrity through mechanisms such as synaptic scaling and pruning, as well as by releasing neurotrophic factors.26 The homeostatic equilibrium...
whether TGF-β signaling is required in mature microglia to maintain their survival and function in the adult brain is not known. Moreover, serum levels of TGF-β1 in this “CNS”Tgfb1KO mouse model were undetectable8, resulting in a potential confound due to altered TGF-β1 levels in per...
