Glial signaling pathways

Glial signaling pathways represent the diverse array of molecular interactions and communication networks between glial cells—including astrocytes, microglia, and oligodendrocytes—and neurons within the central nervous system (Source: Nature Reviews Neuroscience, 2018). These pathways are fundamental for maintaining brain homeostasis, providing metabolic support, and regulating synaptic connectivity and plasticity (Source: Frontiers in Cellular Neuroscience, 2020). Dysregulation of glial signaling is a hallmark of various neurological disorders, where it can drive chronic neuroinflammation, demyelination, and neuronal death (Source: NIH/NIA, 2022). While the term refers to a broad biological system rather than a single protein, specific components such as purinergic receptors, cytokine receptors, and growth factor pathways are targeted by drugs to treat conditions like multiple sclerosis and neurodegenerative diseases (Source: Journal of Neuroinflammation, 2021). Therapeutic strategies often aim to shift glial cells from a pro-inflammatory (neurotoxic) state to a pro-repair (neuroprotective) state to preserve neuronal function (Source: Science Translational Medicine, 2019).
