Antihypertension effect of astragaloside  IV during cerebral ischemia reperfusion in rats
In conclusion, astragaloside IV may alleviate CIR injury partially by lowering systemic blood pressure.PMID:36331022 | DOI:10.3892/mmr.2022.12890

Icaritin inhibits neuroinflammation in a rat cerebral ischemia model by regulating microglial polarization through the GPER-ERK-NF- κB signaling pathway
CONCLUSIONS: These findings indicate that ICT plays roles in inhibiting the inflammatory response and achieving neuroprotection by regulating GPER-ERK-NF-κB signaling and then inhibiting microglial activation and M1 polarization while promoting M2 polarization, which provides a new therapeutic for against cerebral ischemic stroke.PMID:36447154 | DOI:10.1186/s10020-022-00573-7

Adenoviruses-mediated RNA interference targeting cytosolic phospholipase A2 α attenuates focal ischemic brain damage in mice.
Adenoviruses-mediated RNA interference targeting cytosolic phospholipase A2α attenuates focal ischemic brain damage in mice. Mol Med Rep. 2018 Feb 15;: Authors: Wu H, Liu H, Zuo F, Zhang L Abstract Cerebral ischemia injury is a clinical, frequently occurring disease, which causes a heavy burden on society and families. It has been demonstrated that cytosolic phospholipase A2α (cPLA2α) is significant in neurological injury caused by ischemic brain injury, and inhibition of cPLA2α may reduce stroke injury. In the present study, the role of cPLA2α was investigated in a mouse model of middle cerebral...

PAC proton-activated chloride channel contributes to acid-induced cell death in primary rat cortical neurons.
Authors: Osei-Owusu J, Yang J, Del Carmen Vitery M, Tian M, Qiu Z Abstract Severe local acidosis causes tissue damage and pain, and is associated with many diseases, including cerebral and cardiac ischemia, cancer, infection, and inflammation. However, the molecular mechanisms of the cellular response to extracellular acidic environment are not fully understood. We recently identified a novel and evolutionarily conserved membrane protein, PAC (also known as PACC1 or TMEM206), encoding the proton-activated chloride (Cl-) channel, whose activity is widely observed in human cell lines. We demonstrated that genetic del...

Damage to the blood ‑brain barrier and activation of neuroinflammation by focal cerebral ischemia under hyperglycemic condition
Int J Mol Med. 2021 Jul;48(1):142. doi: 10.3892/ijmm.2021.4975. Epub 2021 Jun 3.ABSTRACTHyperglycemia aggravates brain damage caused by cerebral ischemia/reperfusion (I/R) and increases the permeability of the blood‑brain barrier (BBB). However, there are relatively few studies on morphological changes of the BBB. The present study aimed to investigate the effect of hyperglycemia on BBB morphological changes following cerebral I/R injury. Streptozotocin‑induced hyperglycemic and citrate‑buffered saline‑injected normoglycemic rats were subjected to 30 min middle cerebral artery occlusion. Neurological deficits were ...
