Edaravone Dexborneol Alleviates Neuroinflammation by Reducing Neuroglial Cell Proliferation and Suppresses Neuronal Apoptosis/Autophagy in Vascular Dementia Rats
In this study, we established the VD model of rats by bilateral carotid artery occlusion to explore the neuroprotective effect of EDB and its mechanism. Morris Water Maze test was applied to assess the cognitive function of rats. H&E and TUNEL staining were applied to observe the cellular structure of the hippocampus. Immunofluorescence labeling was used to observe the proliferation of astrocytes and microglia. ELISA was applied to examine the levels of TNF-α, IL-1β and IL-6, and RT-PCR was applied to examine their mRNA expression levels. Western blotting was applied to examine apoptosis-related proteins (Bax, Bcl-2,...

Repurposing the K < sub > Ca < /sub > 3.1 Blocker Senicapoc for Ischemic Stroke
Transl Stroke Res. 2023 Apr 24. doi: 10.1007/s12975-023-01152-6. Online ahead of print.ABSTRACTSenicapoc, a small molecule inhibitor of the calcium-activated potassium channel KCa3.1, was safe and well-tolerated in clinical trials for sickle cell anemia. We previously reported proof-of-concept data suggesting that both pharmacological inhibition and genetic deletion of KCa3.1 reduces infarction and improves neurologic recovery in rodents by attenuating neuroinflammation. Here we evaluated the potential of repurposing senicapoc for ischemic stroke. In cultured microglia, senicapoc inhibited KCa3.1 currents with an IC50 of 7...

Epigenetics and stroke: role of DNA methylation and effect of aging on blood-brain barrier recovery
This study aimed to evaluate the epigenetic and transcriptional profile of cerebral microvessels after thromboembolic (TE) stroke to define potential causes of limited BBB recovery. RNA-sequencing and reduced representation bisulfite sequencing (RRBS) analyses were performed using microvessels isolated from young (6 months) and old (18 months) mice seven days poststroke compared to age-matched sham controls. DNA methylation profiling of poststroke brain microvessels revealed 11287 differentially methylated regions (DMR) in old and 9818 DMR in young mice, corresponding to annotated genes. These DMR were enriched in genes en...

Mechanism of Hypoxia-Mediated Smooth Muscle Cell Proliferation Leading to Vascular Remodeling
Biomed Res Int. 2022 Dec 24;2022:3959845. doi: 10.1155/2022/3959845. eCollection 2022.ABSTRACTVascular remodeling refers to changes in the size, contraction, distribution, and flow rate of blood vessels and even changes in vascular function. Vascular remodeling can cause cardiovascular and cerebrovascular diseases. It can also lead to other systemic diseases, such as pulmonary hypertension, pulmonary atherosclerosis, chronic obstructive pulmonary disease, stroke, and ascites of broilers. Hypoxia is one of the main causes of vascular remodeling. Prolonged hypoxia or intermittent hypoxia can lead to loss of lung ventilation,...

Cannabidiol's Multifactorial Mechanisms Has Therapeutic Potential for Aneurysmal Subarachnoid Hemorrhage: a Review
Transl Stroke Res. 2022 Sep 15. doi: 10.1007/s12975-022-01080-x. Online ahead of print.ABSTRACTSubarachnoid hemorrhage (SAH) is a major health burden that accounts for approximately 5% of all strokes. The most common cause of a non-traumatic SAH is the rupture of a cerebral aneurysm. The most common symptom associated with SAH is a headache, often described as "the worst headache of my life." Delayed cerebral ischemia (DCI) is a major factor associated with patient mortality following SAH and is often associated with SAH-induced cerebral vasospasm (CV). Cannabidiol (CBD) is emerging as a potential drug for many therapeutic...

Bone regeneration in osteoporosis: opportunities and challenges
Drug Deliv Transl Res. 2022 Aug 22. doi: 10.1007/s13346-022-01222-6. Online ahead of print.ABSTRACTOsteoporosis is a bone disorder characterised by low bone mineral density, reduced bone strength, increased bone fragility, and impaired mineralisation of bones causing an increased risk of bone fracture. Several therapies are available for treating osteoporosis which include bisphosphonates, anti-resorptive agents, oestrogen modulators, etc. These therapies primarily focus on decreasing bone resorption and do not assist in bone regeneration or offering permanent curative solutions. Additionally, these therapies are associate...

3-Hydroxymorphinan protects against hypoxia-induced cell death in primary astrocyte by regulating Ca2+ influx and the glutamate homeostasis
ConclusionTaken together, these results suggest that 3-HM has a potential to regulate glutamate release from the astrocytic cell death in hypoxic condition and could be used as a promising preventive or therapeutic agent for ischemic brain injury.

Recurrent Transient Ischemic Attack Induces Neural Cytoskeleton Modification and Gliosis in an Experimental Model
Transl Stroke Res. 2022 Jul 22. doi: 10.1007/s12975-022-01068-7. Online ahead of print.ABSTRACTTransient ischemic attack (TIA) presents a high risk for subsequent stroke, Alzheimer's disease (AD), and related dementia (ADRD). However, the neuropathophysiology of TIA has been rarely studied. By evaluating recurrent TIA-induced neuropathological changes, our study aimed to explore the potential mechanisms underlying the contribution of TIA to ADRD. In the current study, we established a recurrent TIA model by three times 10-min middle cerebral artery occlusion within a week in rat. Neither permanent neurological deficit nor ...

Therapeutic Potential of Astrocyte Transplantation
Cell Transplant. 2022 Jan-Dec;31:9636897221105499. doi: 10.1177/09636897221105499.ABSTRACTCell transplantation is an attractive treatment strategy for a variety of brain disorders, as it promises to replenish lost functions and rejuvenate the brain. In particular, transplantation of astrocytes has come into light recently as a therapy for amyotrophic lateral sclerosis (ALS); moreover, grafting of astrocytes also showed positive results in models of other conditions ranging from neurodegenerative diseases of older age to traumatic injury and stroke. Despite clear differences in etiology, disorders such as ALS, Parkinson's, ...

IN BRAIN POST-ISCHEMIC PLASTICITY, Na < sup > + < /sup > /Ca < sup > 2+ < /sup > EXCHANGER 1 AND Ascl1 INTERVENE IN MICROGLIA-DEPENDENT CONVERSION OF ASTROCYTES INTO NEURONAL LINEAGE
Cell Calcium. 2022 May 29;105:102608. doi: 10.1016/j.ceca.2022.102608. Online ahead of print.ABSTRACTThe intricate glia interaction occurring after stroke strongly depend on the maintenance of intraglial ionic homeostasis. Among the several ionic channels and transporters, the plasmamembrane Na+/Ca2+ exchanger (NCX) represents a key player in maintaining astroglial Na+ and Ca2+ homeostasis. Here, using a combined in vitro, in vivo and ex vivo experimental strategy we evaluated whether microglia responding to ischemic injury may influence the morphological and the transcriptional plasticity of post-ischemic astrocytes. Astr...
