Glial cells have emerged as active and dynamic regulators of central nervous system (CNS) function, far beyond their historically perceived supportive role. This review synthesizes the most recent advances in glial biology, highlighting novel molecular mechanisms, cutting-edge imaging methodologies, and translational strategies that redefine their role in health and disease. We emphasize new findings on astrocytic signaling in neurodegeneration, NG2-glia dynamics, and microglial modulation, providing forward-looking perspectives for glia-targeted therapeutic interventions. Recent breakthroughs in high-resolution in vivo imaging, single-cell transcriptomics, and gene-editing platforms are discussed in the context of their ability to unravel glial heterogeneity and functional plasticity. By integrating molecular insights with translational research, this review aims to bridge the gap between basic neuroscience and clinical applications, offering a framework for next-generation CNS therapies.
