Post-hemorrhagic hydrocephalus (PHH) is a severe complication of intraventricular hemorrhage (IVH), yet its underlying mechanisms remain unclear. The glymphatic system (GS), a key pathway involved in cerebrospinal fluid (CSF) circulation and metabolic waste clearance, has recently been implicated in the pathogenesis of PHH. In this study, we employed a mouse model of IVH (n = 6 per group, assessed from 6 h to 28 days post-IVH) to investigate the role of the CCL2/CCR2 signaling axis in GS dysfunc...
