Maternally Expressed Gene 3 negatively regulated Decorin to Supresse Angiogenesis, Proliferation and Migration of Endothelial Cells
CONCLUSION: Our study demonstrated the anti-growth effects of MEG3 on vasculogenesis and migration of endothelial cells. Thus, by blocking the expression of Decorin in HUVECs, the overexpression of MEG3 repressed their development and might potentially alleviate the ischemic stroke.PMID:36443969 | DOI:10.2174/1566524023666221128150800

Hypoxia induces purinergic receptor signaling to disrupt endothelial barrier function
Blood-brain-barrier permeability is regulated by endothelial junctional proteins and is vital in limiting access to and from the blood to the CNS. When stressed, several cells, including endothelial cells, can release nucleotides like ATP and ADP that signal through purinergic receptors on these cells to disrupt BBB permeability. While this process is primarily protective, unrestricted, uncontrolled barrier disruption during injury or inflammation can lead to serious neurological consequences. Purinergic receptors are broadly classified into two families: the P1 adenosine and P2 nucleotide receptors. The P2 receptors are f...

Gas6 Promotes Microglia Efferocytosis and Suppresses Inflammation Through Activating Axl/Rac1 Signaling in Subarachnoid Hemorrhage Mice
AbstractEarly brain injury (EBI) following subarachnoid hemorrhage (SAH) is characterized by rapid development of neuron apoptosis and dysregulated inflammatory response. Microglia efferocytosis plays a critical role in the clearance of apoptotic cells, attenuation of inflammation, and minimizing brain injury in various pathological con ditions. Here, using a mouse SAH model, we aim to investigate whether microglia efferocytosis is involved in post-SAH inflammation and to determine the underlying signaling pathway. We hypothesized that TAM receptors and their ligands regulate this process. To prove our hypothesis, the...

Cornin protects against cerebral ischemia/reperfusion injury by preventing autophagy via the PI3K/Akt/mTOR pathway
CONCLUSIONS: These results indicate that cornin improved neurological recovery after cerebral ischemia injury by preventing astrocytes autophagy induced by CI/R via the PI3K/Akt/mTOR signaling pathway.PMID:36280856 | DOI:10.1186/s40360-022-00620-3

Cycloastragenol suppresses M1 and promotes M2 polarization in LPS-stimulated BV-2 cells and ischemic stroke mice
This study investigated the effect of CAG on the phenotype polarization of microglia in lipopolysaccharide (LPS)-stimulated BV-2 mouse microglial cells and ischemic stroke mice. In LPS-treated BV-2 cells, we found that CAG significantly reduced the expression of M1 markers, including pro-inflammatory cytokines and enzymes. In contrast, CAG promoted the expression of M2 markers, including anti-inflammatory cytokines and growth factor. In addition, CAG inhibited the activation of nuclear factor-κB (NF-κB) and enhanced the activation of nuclear factor E2-related factor 2 (Nrf2) and the expression of its downstream heme oxyg...

Retinoic Acid Prevents the Neuronal Damage Through the Regulation of Parvalbumin in an Ischemic Stroke Model
In conclusion, retinoic acid contributes to the preservation of neurons from ischemic stroke by controlling parvalbumin expression and apoptosis-related proteins.PMID:36245066 | DOI:10.1007/s11064-022-03769-9
