Protective effect of low-intensity transcranial ultrasound stimulation after differing delay following an acute ischemic stroke.
CONCLUSION: In the event of an acute ischemic stroke, LITUS can inhibit the decrease of ADC and the effect is closely related to the delay in treatment. The earlier the ultrasound intervention, the better the protective effect. PMID: 30552999 [PubMed - as supplied by publisher]

Chuanzhitongluo regulates microglia polarization and inflammatory response in acute ischemic stroke
CONCLUSIONS: These results indicate that CZTL alleviates neuroinflammation and brain damage after AIS in mice, which may be mediated by modulating microglia polarization.PMID:36152772 | DOI:10.1016/j.brainresbull.2022.09.015

The neuroprotective effects of Insulin-Like Growth Factor 1 via the Hippo/YAP signaling pathway are mediated by the PI3K/AKT cascade following cerebral ischemia/reperfusion injury
Brain Res Bull. 2021 Oct 27:S0361-9230(21)00309-9. doi: 10.1016/j.brainresbull.2021.10.017. Online ahead of print.ABSTRACTInsulin-like growth factor 1 (IGF-1) has neuroprotective actions, including vasodilatory, anti-inflammatory, and antithrombotic effects, following ischemic stroke. However, the molecular mechanisms underlying the neuroprotective effects of IGF-1 following ischemic stroke remain unknown. Therefore, in the present study, we investigated whether IGF-1 exerted its neuroprotective effects by regulating the Hippo/YAP signaling pathway, potentially via activation of the PI3K/AKT cascade, following ischemic str...

cPKC γ alleviates ischemic injury through modulating synapsin Ia/b phosphorylation in neurons of mice.
cPKCγ alleviates ischemic injury through modulating synapsin Ia/b phosphorylation in neurons of mice. Brain Res Bull. 2018 Jul 14;: Authors: Zhang N, Zhu H, Han S, Sui L, Li J Abstract Conventional protein kinase C (cPKC)γ and synapsin Ia/b have been implicated in the development of ischemic stroke, but their relationships and functions are unclear. In the present study, the oxygen-glucose deprivation (OGD)-induced ischemic insult in primary cultured cortical neurons in vitro and middle cerebral artery occlusion (MCAO)-induced ischemic stroke model in vivo were used to elucidate the function of cPKC...

Neuroprotective effects of matrix metalloproteinases in cerebral ischemic rats by promoting activation and migration of astrocytes and microglia.
This study was designed to investigate whether early MMPs inhibition could promote the recovery of cerebral ischemia. Male Sprague-Dawley rats underwent right middle cerebral artery occlusion (MCAO) for 1 h and reperfusion. The rats were divided into three groups: sham + vehicle (S + V) group, MCAO + vehicle (M + V) group, and MCAO + GM6001 (M + G) group. Infarct volume was assessed by 2, 3, 5-triphenyltetrazolium chloride (TTC) staining, and the expression of GFAP, IBA1, p-ERK, ERK, and MMP9 were evaluated by Western blot and immunofluorescence staining on 1, 4, 7, and 14 days after MCAO. Neurona...

Environmental enrichment enhances post-ischemic cerebral blood flow and functional hyperemia in the ipsilesional somatosensory cortex.
This study aimed to investigate the effect of environmental enrichment treatment on post-ischemic cerebral blood flow and functional hyperemia in the ipsilesional primary somatosensory cortex of rats. With laser speckle imaging, we were able to monitor the resting cerebral blood flow alteration in the middle cerebral artery occlusion model. Both 3- and 28-day post-ischemic infarct volumes were then examined with triphenyltetrazolium chloride and cresyl violet staining, respectively. We found that an exposure to environmental enrichment was associated with higher post-ischemic cerebral blood flow and less brain tissue loss ...
