AIMS: Ethyl pyruvate (EP) mediates protective effects after neuronal injury. Besides a direct conservation of damaged neurons, the modulation of indigenous glial cells has been suggested as one important mechanism for EP-related neuroprotection. However, the specific contribution of glial cells is still unknown. METHODS: Organotypic hippocampal slice cultures (OHSC) were excitotoxically lesioned by 50 μmol/L N-methyl-D-aspartate (NMDA, for 4 hours) or left untreated...

AIMS: Astroglial-fibrotic scar formation following central nervous system injury can help repair blood-brain barrier and seal the lesion, whereas it also represents a strong barrier for axonal regeneration. Intensive preclinical efforts have been made to eliminate/reduce the inhibitory part and, in the meantime, preserve the beneficial role of astroglial-fibrotic scar. METHODS: In this study, we established an in vitro system, in which coculture of astrocytes and meningeal fibroblasts was treated with exogenous transforming growth factor-β1 (TGF-β1) to form astroglial-fibrotic scar-like cell clusters, and thereby evaluated the efficacy of RNAi targeting ephrin-B2 in preventing scar formation from the very beginning...

AIMS: To investigate the roles of N-myc downstream-regulated gene 2 (NDRG2) in the pathology of aging and neurodegenerative disease such as Alzheimer's disease (AD). RESULTS: In this study, we confirmed the upregulation of NDRG2 in the brains of aging and AD animal models. To explore the role of NDRG2 in the pathology of AD at molecular level, we conducted a cell-based assay of highly expressed wild-type human APP695 SK-N-SH cells (SK-N-SH APPwt). By silencing and overexpressing gene of NDRG2, we demonstrated that NDRG2-mediated increase in Aβ1-42 was through the pathways of BACE1 and GGA3...

Brain is one of the most complex organs in human. The current brain research is mainly based on the animal models and traditional cell culture. However, the inherent species differences between humans and animals as well as the gap between organ level and cell level make it difficult to study human brain development and associated disorders through traditional technologies. Recently, the brain organoids derived from pluripotent stem cells have been reported to recapitulate many key features of human brain in vivo, for example recapitulating the zone of putative outer radial glia cells...

AIMS: Prenatal alcohol exposure (PAE) is associated with a higher likelihood of developing generalized tonic-clonic seizures (GTCS) in infants and children. However, experimental studies of PAE-related seizures have yielded conflicting results. Here, we investigated the effect of acute PAE on N-methyl-D-aspartate (NMDA)-induced seizures in developing rats. METHODS: Pregnant Sprague Dawley rats were given an oral dose of either ethanol (5 g/kg body weight) or vehicle on embryonic day 18...

INTRODUCTION: Apolipoprotein E4 (APOE4) is a major genetic risk factor for late-onset sporadic Alzheimer disease. Emerging evidence demonstrates a hippocampus-associated learning and memory deficit in aged APOE4 human carriers and also in aged mice carrying human APOE4 gene. This suggests that either exogenous APOE4 or endogenous APOE4 alters the cognitive profile and hippocampal structure and function. However, little is known regarding how Apoe4 modulates hippocampal dendritic morphology, synaptic function, and neural network activity in young mice...

AIMS: Cerebral small vessel disease (SVD) is the leading cause of vascular dementia. Although the most of cases are sporadic, familial monogenic causes have been identified in a growing minority of patients. CADASIL, due to mutations of NOTCH3 gene, is the most common genetic SVD, and CARASIL, linked to HTRA1 gene mutations, is a rare but well known autosomal recessive SVD. Recently, also heterozygous HTRA1 mutations have been described in patients with familial SVD. To detect a genetic cause of familial SVD, we performed mutational analysis of HTRA1 gene in a large cohort of Italian NOTCH3-negative patients...

AIMS: Thioredoxin-interacting protein (TXNIP) is associated with activation of oxidative stress through inhibition of thioredoxin (Trx). However, some evidences point out that TXNIP acts as a scaffolding protein in signaling complex independent of cellular redox regulation. The autophagy-lysosomal pathway plays important roles in the clearance of misfolded proteins and dysfunctional organelles. Lysosomal dysfunction has been involved in several neurodegenerative disorders including Parkinson's disease (PD)...

AIM: Brain inflammation is associated with several brain diseases such as multiple sclerosis (MS), a disease characterized by demyelination. Whether prenatal immune challenge affects demyelination-induced inflammation in the white matter during adulthood is unclear. In the present study, we used a well-established experimental model of focal demyelination to assess whether prenatal immune challenge affects demyelination-induced inflammation. METHODS: Pregnant rats were injected with either lipopolysaccharide (100 μg/kg, ip) or pyrogen-free saline...

AIMS: Accumulated evidence indicates that cerebral metabolic features, evaluated by proton magnetic resonance spectroscopy ((1) H-MRS), are sensitive to early mitochondrion dysfunction associated with mitochondrial encephalomyopathy (ME). The metabolite ratios of lactate (lac)/Cr, N-acetyl aspartate (NAA)/creatine (Cr), total choline (tCho)/Cr, and myoinositol (mI)/Cr are measured in the infarct-like lesions by (1) H-MRS and may reveal metabolic changes associated with ME. However, the application of this molecular imaging technique in the investigation of the pathology of ME subtypes is unknown...

Recent studies have indicated that long noncoding RNAs (lncRNAs) play important roles in multiple processes, such as epigenetic regulation, gene expression regulation, development, nutrition-related and other diseases, toxic response, and response to drugs. Although the functional roles and mechanisms of several lncRNAs have been discovered, a better understanding of the vast majority of lncRNAs remains elusive. To understand the functional roles and mechanisms of lncRNAs is critical because these transcripts represent the majority of the transcriptional output of the mammalian genome...
