OBJECTIVES: Evidence suggests that brain-derived neurotrophic factor (BDNF) and glial cell line -derived neurotrophic factor (GDNF) are important in the regulation of synaptic plasticity, which plays a key role in the cognitive processes in psychiatric disorders. Our work aimed at exploring the associations between serum BDNF and GDNF levels and cognitive functions in first-episode drug-naïve (FEDN) patients with schizophrenia. METHODS: The BDNF and GDNF levels of 58 FEDN patients and 55 age- and sex-matched healthy controls were measured and test subjects were examined using several neurocognitive tests including the verbal fluency test (VFT), the trail making test (TMT), the digit span test (DST), and the Stroop test...

REVIEW
Wei-Lin Kong, Yuan-Yuan Peng, Bi-Wen Peng
Transient receptor potential vanilloid type 1 channel (TRPV1), as a ligand-gated non-selective cation channel, has recently been demonstrated to have wide expression in the neuro-immune axis, where its multiple functions occur through regulation of both neuronal and non-neuronal activities. Growing evidence has suggested that TRPV1 is functionally expressed in glial cells, especially in the microglia and astrocytes. Glial cells perform immunological functions in response to pathophysiological challenges through pro-inflammatory or anti-inflammatory cytokines and chemokines in which TRPV1 is involved...

Endothelins (ET) are a family of highly active neuropeptides with manifold influences via ET receptors (ETR) in both the peripheral and central nervous systems. We have shown previously that satellite glial cells (SGCs) in mouse trigeminal ganglia (TG) are extremely sensitive to ET-1 in evoking [Ca(2+)]in increase, apparently via ETBR activation, but there is no functional information on ETR in SGCs of other peripheral ganglia. Here we tested the effects of ET-1 on SGCs in nodose ganglia (NG), which is sensory, and superior cervical ganglia (Sup-CG), which is part of the sympathetic nervous system, and further investigated the influence of ET-1 on SGCs in TG...

Background.: Glioblastoma cell-initiated vascularization is an alternative angiogenesis called vasculogenic mimicry. However, current knowledge on the mechanism of de novo vessel formation from glioblastoma stem cells (GSCs) is limited. Methods.: Sixty-four glioblastoma samples from patients and 10 fluorescent glioma xenograft samples were examined by immunofluorescence staining for endothelial marker (CD34 and CD31) and glial cell marker (glial fibrillary acidic protein [GFAP]) expression...

Background.: Diffuse intrinsic pontine glioma (DIPG) is a high-grade brainstem glioma of children with dismal prognosis. There is no single unifying model about the cell of origin of DIPGs. Proliferating cells in the developing human and mouse pons, the site of DIPGs, express neural stem/progenitor cell (NPC) markers, including Sox2, nestin, vimentin, Olig2, and glial fibrillary acidic protein, in an overlapping and non-overlapping manner, suggesting progenitor cell heterogeneity in the pons...

The up-regulation of thioredoxin reductase-1 (TrxR1) is detected in more than half of gliomas, which is significantly associated with increased malignancy grade and recurrence rate. The biological functions of NADPH-dependent TrxR1 are mainly associated with reduced thioredoxin-1 (Trx1) which plays critical roles in cellular redox signaling and tumour radio-resistance. Our previous work has proved that TP53 induced glycolysis and apoptosis regulator (TIGAR) knockdown could notably radiosensitize glioma cells...

Increasing evidence has indicated that activated glial cells releasing nociceptive factors, such as interleukins and chemokines, are of key importance for neuropathic pain. Significant changes in the production of nociceptive factors are associated with the low effectiveness of opioids in neuropathic pain. Recently, it has been suggested that CCL2/CCR2 signaling is important for nociception. Here, we studied the time course changes in the mRNA/protein level of CD40/Iba-1, CCL2 and CCR2 in the spinal cord/dorsal root ganglia (DRG) in rats following chronic constriction injury (CCI) of the sciatic nerve...

Neuroblastoma stem cells (NSCs) can cause drug resistance and tumor recurrence. This study aimed to enhance the lytic effect of dendritic cells (DCs) co-cultured with cytokine-induced killer (CIK) cells. NSCs were obtained by suspension culture, and DC-CIK cells were loaded with extracted NSC membrane-based microparticles (MMPs) before evaluating the lytic effect of DC-CIK cells on NSCs. After inhibiting the function or expression of human leukocyte antigen-E (HLA-E) in NSCs by anti-HLA-E monoclonal antibody or siRNA, the DC-CIK cell lytic effect on NSCs was re-assessed...

Astrocytes have in recent years become the focus of intense experimental interest, yet markers for their definitive identification remain both scarce and imperfect. Astrocytes may be recognized as such by their expression of glial fibrillary acidic protein (GFAP), glutamine synthetase (GS), glutamate transporter 1 (GLT1)quaporin-4 (AQP4)ldehyde dehydrogenase 1 family member L1 (ALDH1L1)nd other proteins. Yet these proteins may all be regulated both developmentally and functionally, restricting their utility...

Traumatic brain injury (TBI) is a serious public health problem, often with devastating consequences for patients and their families. Affordable and timely therapies can have a substantial impact on outcomes in severe TBI. Despite the common use of sedatives and anesthetics in the acute phase of TBI management, their effect on glial cells is not well understood. We investigated the effect of a commonly used sedative, pentobarbital, on glial cells and their uptake of nanoparticles. First, we studied how pentobarbital affects BV2 mouse microglial cells in culture...

BACKGROUND: Isolation of neurons from the adult mouse CNS is important in order to study their gene expression during development or the course of different diseases. NEW METHODS: Here we present two different methods for the enrichment or isolation of neurons from adult mouse CNS. These methods: are either based on flow cytometry sorting of eYFP expressing neurons, or by depletion of non-neuronal cells by sorting with magnetic-beads. RESULTS: Enrichment by FACS sorting of eYFP positive neurons results in a population of 62...

The incretin hormones glucagon-like peptide (GLP)-1 and glucose-dependent insulinotropic polypeptide (GIP) are primarily known for their metabolic function in the periphery. GLP-1 and GIP are secreted by intestinal endocrine cells in response to ingested nutrients. Both GLP-1 and GIP stimulate the production and release of insulin from pancreatic β cells as well as exhibit several growth-regulating effects on peripheral tissues. GLP-1 and GIP are also present in the brain, where they provide modulatory and anti-apoptotic signals to neurons...

The neuropeptide pituitary adenylate cyclase activating polypeptide (PACAP) has two active forms, PACAP1-27 and PACAP1-38. Among the well-established actions are PACAP's neurotrophic and neuroprotective effects, which have also been proven in models of different retinopathies. The route of delivery is usually intravitreal in studies proving PACAP's retinoprotective effects. Recently, we have shown that PACAP1-27 delivered as eye drops in benzalkonium-chloride was able to cross the ocular barriers and exert retinoprotection in ischemia...

Drug delivery into the central nervous system (CNS) is challenging due to the blood-brain barrier (BBB) and drug delivery into the brain overcoming the BBB can be achieved using nanoparticles such as dendrimers. The conventional cationic dendrimers used are highly toxic. Therefore, the present study investigates the role of novel mixed surface dendrimers, which have potentially less toxicity and can cross the BBB when administered through the carotid artery in mice. In vitro experiments investigated the uptake of amine dendrimers (G1-NH₂ and G4-NH₂) and novel dendrimers (G1-90/10 and G4-90/10) by primary cortical cultures...

Geraniol, a plant derived monoterpene, has been extensively studied and showed a wide variety of beneficial effects. The aim of this study was to investigate the therapeutic effect of geraniol on functional recovery and neuropathic pain in rats with spinal cord injury (SCI). Rats received a clip-compression SCI and were treated with geraniol 6 hours following SCI. Treatment of SCI rats with geraniol markedly improved locomotor function, and reduced sensitivity to the mechanical allodynia and thermal hyperalgesia...

Primary diffuse leptomeningeal gliomatosis (PDLG) is characterized by diffuse infiltration of the leptomeningeal space by neoplastic glial cells without evidence of intra-parenchymatous primary tumor. We report a case of PDLG in a 68-year-old man, who died 1 month after onset of symptoms. The diagnosis was made on autopsy data. We discuss the particularities of this entity, which is not registered in the WHO classification of tumors of the central nervous system (2016). In case of an unexplained inflammatory meningeal process and in the presence of atypical cells in the cerebrospinal fluid, PDLG needs to be considered...

Carotid body (CB) chemoreceptor (type I) cells can synthesize and release 5-hydroxytryptamine (5-HT) and increased autocrine-paracrine 5-HT2 receptor signalling contributes to sensory long-term facilitation during chronic intermittent hypoxia (CIH). However, recent studies suggest that adjacent glial-like type II cells can respond to CB paracrine signals by elevating intracellular calcium (Δ[Ca(2+) ]i ) and activating carbenoxolone-sensitive, ATP-permeable, pannexin-1 (Panx-1)-like channels. Here, using dissociated rat CB cultures, we found that 5-HT induced Δ[Ca(2+) ]i responses in a subpopulation of type I cells, and in most (∼67%) type II cells identified by their sensitivity to the P2Y2 receptor agonist, UTP...

MicroRNAs are small noncoding RNAs that work posttranscriptionally to negatively regulate protein levels. They influence neuronal and glial structure and function, neuroinflammatory signaling, cell death, neurogenesis, and other processes relevant to epileptogenesis. Functional studies using oligonucleotide inhibitors (antagomirs) and mimics (agomirs) to modulate microRNAs in rat and mouse models of epilepsy show effects on evoked and spontaneous seizures and attendant neuropathology. The present review summarizes recent findings and points to gaps in our knowledge of the underlying mechanisms and directions for the future...
