Traumatic brain injury is a global health crisis, causing significant death and disability worldwide. Neuroinflammation that follows traumatic has serious consequences for neuronal survival cognitive impairments, with astrocytes involved in this response. Following injury, rapidly become reactive, astrogliosis propagates from the core to distant regions. Homeostatic astroglial proteins are downregulated near core, while pro-inflammatory genes overexpressed. This altered gene expression considered pathological remodeling of produces recovery. In addition, glial scar formed by reactive initially necessary limit immune cell infiltration, but long term impedes axonal reconnection functional Current therapeutic strategies focused on preventing acute complications. Statins, cannabinoids, progesterone, beta-blockers, cerebrolysin demonstrate neuroprotective benefits most them have not been studied context astrocytes. review, we discuss signaling pathways activated following some potential new aimed modulate responses especially using cell-targeted miRNAs or lncRNA, viral vectors, repurposed drugs.

Aquaporins (AQPs), particularly AQP4, play a crucial role in regulating fluid dynamics the brain, impacting development and resolution of edema following traumatic brain injury (TBI). This review examines alterations AQP expression localization post-injury, exploring their effects on overall outcomes. We discuss underlying molecular mechanisms expression, highlighting potential therapeutic strategies to modulate function. These insights provide comprehensive understanding AQPs TBI suggest novel approaches for improving clinical outcomes through targeted interventions.

The Cannabinoid 2 Receptor (CB2R) has been found to provide immunological modulation in different cell types. More recently, detection of CB2R the cerebral endothelium suggests a possible role resolution inflammation at level blood-brain-barrier (BBB). Here, notion that upregulation brain endothelial cells could be exploited promote vascular protection and BBB integrity was evaluated. Targeting activation accomplished by novel highly specific chromenopyrazole based agonist, PM289. This study demonstrates is induced as early 8 h cortical vasculature an experimental mouse model TBI. Unlike CB2R, CB1R marginally detected not significantly induced. In human line, hCMEC/D3 cells, similar induction observed upon stimulation with TNFα. Analysis transendothelial electrical resistance shows PM289 markedly prevented barrier-leakiness also responsible for maintaining barrier. five-fold increase ICAM1 expression stimulated diminished due activation. Utilizing wounding assays, results showed wound repair nearly half time when agonist present compared untreated control. Lastly, mechanistically, effects may explained inhibition p65 NFκB subunit. Overall, these studies support targeting activating aid context neuroinflammation.
