Gene therapy of adeno-associated virus (AAV) vectors in preclinical models of ischemic stroke
CNS Neurosci Ther. 2023 Aug 8. doi: 10.1111/cns.14392. Online ahead of print.ABSTRACTStroke has been associated with devastating clinical outcomes, with current treatment strategies proving largely ineffective. Therefore, there is a need to explore alternative treatment options for addressing post-stroke functional deficits. Gene therapy utilizing adeno-associated viruses (AAVs) as a critical gene vector delivering genes to the central nervous system (CNS) gene delivery has emerged as a promising approach for treating various CNS diseases. This review aims to provide an overview of the biological characteristics of AAV vec...

Ca2+ ‐dependent activator protein for secretion 1 promotes spontaneous recovery in ischemic stroke by regulating BDNF secretion
In conclusion, CAPS1 regulates neurogenesis by upregulating BDNF release in the hippocampus, which finally facilitate spontaneous recovery after ischemic stroke.

SerpinA3N attenuates ischemic stroke injury by reducing apoptosis and neuroinflammation
CONCLUSIONS: SerpinA3N is expressed in astrocytes and penumbra neurons after stroke in mice. It reduces brain damage possibly via interacting with clusterin and inhibiting neuronal apoptosis and neuroinflammation.PMID:34897996 | DOI:10.1111/cns.13776

Morinda officinalis oligosaccharides alleviate depressive-like behaviors in post-stroke rats via suppressing NLRP3 inflammasome to inhibit hippocampal inflammation
CONCLUSION: Overall, our study reveals the antidepressive effect of MOOs on PSD rats through modulation of microglial NLRP3 inflammasome. We also provide a novel insight into hippocampal inflammation response in PSD pathology and put forward NLRP3 inflammasome as a potential therapeutic target for PSD.PMID:34559953 | DOI:10.1111/cns.13732

Issue Cover (March 2021)
Front cover:Necrostatin ‐1 (Nec‐1) has been shown to inhibit necroptosis. The mitochondrial protein Bcl‐2/adenovirus E1B 19‐kDa interacting protein 3 (BNIP3) activates a type of caspase‐independent cell death that is similar to necroptosis. Here we show that Nec‐1 is protective against death of neurons and olig odendrocytes in traumatic brain injury (TBI) in mice and in ischemic stroke in rats by inhibiting BNIP3; Nec‐1 prevents BNIP3 from integration into mitochondria to block the BNIP3 cell death pathway. The data suggest that Nec‐1 is a novel inhibitor for BNIP3.Image Content: Nec‐1 preserves structur...

LRG1 Promotes Apoptosis and Autophagy through the TGFβ-smad1/5 Signaling Pathway to Exacerbate Ischemia/Reperfusion Injury
In this study, we discussed the function and mechanism of LRG1 in acute ischemic stroke from both basic and clinical research points of view. Mice underwent transient middle cerebral artery occlusion (tMCAO) surgery two weeks after LRG1 was overexpressed by the delivery of adeno-associated virus (AAV). For wild-type mice, both the protein and the transcript of LRG1 in the brain tissue were elevated after tMCAO. Meanwhile, the serum levels of LRG1 were decreased after tMCAO. The neuronal injury was shown aggravated in the AAV-LRG1 group (AAV-LRG1 mice with tMCAO) through infarction volume, neurological score, HE, and Nissl ...

Neuroscience is the Next Oncology
by Michael D. Ehlers, MD, PhD Dr. Ehlers is with Biogen in Cambridge, Massachusetts. Innov Clin Neurosci. 2018;15(3–4):15–16 Funding: No funding was received for the preparation of this article. Disclosures: Dr. Ehlers is an employee and shareholder at Biogen Inc. in Cambridge, Massachusetts. Prominent and expensive failures in Alzheimer’s disease therapies have led to a contagious belief system in some parts of the biopharma industry that neuroscience is just too hard, too risky, and too uncertain. But, might this belief system itself be a residual bias of the past? Close inspection reveals all the signs of a coming...

Overexpression of Adiponectin Improves Neurobehavioral Outcomes After Focal Cerebral Ischemia in Aged Mice.
CONCLUSIONS: Our results demonstrate that APN overexpression reduces ischemic brain injury and improves neurobehavioral function recovery in aged mice than in young mice, suggesting APN is more beneficial in aged animals after ischemic stroke. PMID: 24164711 [PubMed - as supplied by publisher]

Changes in Levels of Hypoxia-Induced Mediators in Rat Hippocampus During Chronic Cerebral Hypoperfusion.
Abstract The hypoxia-inducible factor (HIF)-mediated signaling pathway is an adaptive and protective mechanism that is triggered by hypoxia, ischemia, and other pathophysiological conditions. The expression of HIF-1α and downstream genes, some of which are pro-apoptotic whereas others are pro-survival, is up-regulated in ischemic stroke. Interestingly, however, the effects of HIF-1α activation are different in the early and late stages of acute cerebral ischemia, and these differences may depend on the duration and severity of hypoxia. Therefore, in the present study, we investigated the effect of HIF-1α activa...
