Microglia maintain structural integrity during fetal brain morphogenesis Microglia accumulate at fetal cortical boundaries where they preserve tissue integrity in the context of morphogenetic constraints. These immune cells prev... - 《Cell》 被引量: 0发表: 2024年 Stress-induced recruitment of bone ...
Specifically, HA influences tip proliferation responses in the hippocampus following vessel ablation, where juxtavascular microglia maintain their proliferative response even far away from the ablation site, and parenchymal microglia close to the ablation site exhibit heightened proliferation including an ...
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 ...
Brain tissue was carefully extracted to maintain structural integrity and allowed to incubate in 4% PFA overnight at 8°C. Brains were then thoroughly washed on a plate shaker with 1x phosphate buffered saline (PBS) three times over approximately 1 hr. Perfused and PBS-washed brains were ...
Microgliaare macrophage-likeimmune cellsof thecentral nervous systemthat play major roles in both health and disease[1,2]. In health,microgliaare highlymotile cellsthat survey their surrounding environment to maintainhomeostasis[3], promotesynaptogenesis, and regulate the integrity of the blood–brain ...
structural remodeling of neurons or release of neuromodulators [169]. These parainflammatory mechanisms are also accompanied by cell autonomous mechanisms in neurons, such as dendritic retraction and degradation of glutamate receptors, which maintain this neuronal phenotype [179,197,200,203]. Collectively...

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...
Microglia maintain neuronal survival and regulate neurogenesis throughout both the prenatal and postnatal stages of development. Microglia limit the production of cortical neurons by phagocytosing neural precursor cells99; at the same time, microglia also promote neurogenesis, as microglia depletion in mic...
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...
