Journal Article Glia · March 2024 Astrocytes are a heterogeneous population of central nervous system glial cells that respond to pathological insults and injury by undergoing a transformation called "reactivity." Reactive astrocytes exhibit distinct and context-dependent cellular, molecul ... Full text Open Access Cite

Longitudinal scRNA-seq analysis in mouse and human informs optimization of rapid mouse astrocyte differentiation protocols.

Journal Article Nature neuroscience · October 2023 Macroglia (astrocytes and oligodendrocytes) are required for normal development and function of the central nervous system, yet many questions remain about their emergence during the development of the brain and spinal cord. Here we used single-cell/single ... Full text Open Access Cite

The Drosophila chemokine-like Orion bridges phosphatidylserine and Draper in phagocytosis of neurons.

Journal Article Proceedings of the National Academy of Sciences of the United States of America · June 2023 Phagocytic clearance of degenerating neurons is triggered by "eat-me" signals exposed on the neuronal surface. The conserved neuronal eat-me signal phosphatidylserine (PS) and the engulfment receptor Draper (Drpr) mediate phagocytosis of degenerating neuro ... Full text Open Access Cite

Proteomic Alterations and Novel Markers of Neurotoxic Reactive Astrocytes in Human Induced Pluripotent Stem Cell Models.

Journal Article Frontiers in molecular neuroscience · January 2022 Astrocytes respond to injury, infection, and inflammation in the central nervous system by acquiring reactive states in which they may become dysfunctional and contribute to disease pathology. A sub-state of reactive astrocytes induced by proinflammatory f ... Full text Open Access Cite

Low FoxO expression in Drosophila somatosensory neurons protects dendrite growth under nutrient restriction.

Journal Article eLife · May 2020 During prolonged nutrient restriction, developing animals redistribute vital nutrients to favor brain growth at the expense of other organs. In Drosophila, such brain sparing relies on a glia-derived growth factor to sustain proliferation of neural ... Full text Open Access Cite
