Article Title: A hydrogel-based nanoparticles sustained-release system selectively targeting pro-inflammatory microglia for spinal cord injury repair.
Article Snippet: Spinal cord injury (SCI) often results in irreversible neurological deficits, primarily due to chronic neuroinflammation driven by activated proinflammatory microglia.. Effective therapeutic interventions require both precise targeting of pathological immune cells and sustained modulation of the inflammatory microenvironment.. Here, we present a cell specific, hydrogel-based nanoparticle system (MG1-MM@Candesartan-Gel) designed for the selective and prolonged delivery of the angiotensin II type 1 receptor (AT1R) antagonist Candesartan to proinflammatory microglia.
