Activation of neuronal Ras ‐related C3 botulinum toxin substrate 1 (Rac1) improves post‐stroke recovery and axonal plasticity in mice
We propose that activation of neuronal Rac1 mediates the release of BDNF via PAK1 signaling, which further promotes axonal plasticity and alleviates astrogliosis, and eventually contributes to functional recovery after brain ischemia. Targeting neuronal Rac1 may offer a potential therapeutic target for promoting brain remapping and functional recovery after stroke. AbstractLong-term disability after stroke is common but the mechanisms of post-stroke recovery remain unclear. Cerebral Ras-related C3 botulinum toxin substrate (Rac) 1 contributes to functional recovery after ischemic stroke in mice. As Rac1 plays divergent rol...

Activation of Neuronal Ras ‐Related C3 Botulinum Toxin Substrate 1 (Rac1) Improves Post‐Stroke Recovery and Axonal Plasticity in Mice
AbstractLong ‐term disability after stroke is common but the mechanisms of post‐stroke recovery is unclear. Cerebral Ras‐related C3 botulinum toxin substrate (Rac) 1 contributes to functional recovery after ischemic stroke in mice. As Rac1 plays divergent roles in individual cell types after central neural system injury, we herein examined the specific role of neuronal Rac1 in post‐stroke recovery and axonal regeneration. Young male mice were subjected to 60‐minutes middle cerebral artery occlusion (MCAO). Inducible deletion of neuronal Rac1 by daily intraperitoneal injection of tamoxifen (2 mg/4 0 g) into Thy1�...
