Despite significant progress in developing new drugs for seizure control, epilepsy still affects 1% of the global population and is drug-resistant in more than 30% of cases. To improve the therapeutic efficacy of epilepsy medication, a promising approach is to deliver anti-epilepsy drugs directly to affected brain areas using local drug delivery systems. The drug delivery systems must meet a number of criteria, including high drug loading efficiency, biodegradability, neuro-cytocompatibility and predictable drug release profiles...

The present communication investigates an application of alginate encapsulation technology to the differentiation of the embryonic cancer stem NTera2 cells (NT2) into dopamine-producing cells. The encapsulation of cells in polymeric beads allows their immune isolation and makes them eligible for transplantation, thus representing a promising biotech tool for the delivery of biologically active compounds to the brain. The polysaccharide alginate is one of the most commonly used material for this procedure since it is well tolerated by various tissues, including the brain...

PURPOSE OF REVIEW: Glioblastoma multiforme (GBM) is the most common primary malignant brain tumor in adults with a dismal prognosis despite aggressive multimodal management thus novel treatments are urgently needed. Gene therapy is a versatile treatment strategy being investigated in multiple cancers including GBM. In gene therapy, a variety of vectors or "carriers" are used to deliver genes designed for different anti-tumoral effects. Gene delivery vehicles and approaches to treatment will be addressed in this review...

Neuro-Behçet's disease (NBD) is subcategorized into parenchymal-NBD (P-NBD) and non-parenchymal-NBD types. Recently, P-NBD has been further subdivided into acute P-NBD (A-P-NBD) and chronic progressive P-NBD (CP-P-NBD). Although an increasing number of studies have reported the various clinical features of A-P-NBD and CP-P-NBD over the last two decades, there was a considerable inconsistency. Two investigators systematically searched four electrical databases to detect studies that provided sufficient data to assess the specific characteristics of A-P-NBD and CP-P-NBD...

Tailored nanocarriers have gained huge research focus for brain drug delivery, aimed at combating several neuro-oncological conditions, such as the glioblastoma multiforme (GBM). The progress of knowledge on the pathogenesis of GBM has allowed identifying the major hurdles for efficient treatment, encompassing biological interfaces (blood-brain barrier and blood-brain tumour barrier), specificities of tumour microenvironment, as well as both bulk and glioma stem cell subpopulations. These findings provided new insights into the molecular basis of GBM, being a strong driving force behind development of targeted nanomedicines in this area...

Vanadium is a potentially toxic environmental pollutant and induces oxidative damage in biological systems including the central nervous system (CNS). Its deposition in brain tissue may be involved in the pathogenesis of certain neurological disorders which after prolonged exposure can culminate into more severe pathology. Most studies on vanadium neurotoxicity have been done after acute exposure but in reality some populations are exposed for a lifetime. This work was designed to ascertain neurodegenerative consequences of chronic vanadium administration and to investigate the progressive changes in the brain after withdrawal from vanadium treatment...

Recent investments in research associated with the discovery of specific tumor biomarkers important for efficient diagnosis and prognosis are beginning to bear fruit. Key biomarkers could potentially outweigh traditional radiological or pathological methods by enabling specificity of early detection, when coupled with tumor molecular profiling and clinical associations. Only few biomarkers are approved by regulatory authorities for Central Nervous System Tumors (CNSTs), despite the evaluation of a large number of CNST related markers during clinical trials...

Transplantation of a biosynthetic nerve conduit carrying neuro-protective cytokines is promising for treating peripheral nerve injury. Here we developed a novel strategy for repairing sciatic nerve injury by EPO-loaded Chitosan nerve conduit (EPO/Chi) and sandwiched-in transplantation of mesenchymal stem cells (MSCs). Then, the beneficial effect of EPO/Chi + MSCs on nerve regeneration was also further investigated by in vitro cellular experiments. In vivo experiment showed that combination of EPO-loaded Chitosan nerve conduit with MSCs could significantly accelerate nerve healing and improve morphological repair...

The olfactory mucosa (OM) has the unique characteristic of performing an almost continuous and lifelong neurogenesis in response to external injuries, due to the presence of olfactory stem cells that guarantee the maintenance of the olfactory function. The easy accessibility of the OM in humans makes these stem cells feasible candidates for the development of regenerative therapies. In this report we present a detailed characterization of a patient-derived OM, together with a description of cell cultures obtained from the OM...

Current research in neural tissue-engineering is focused on the development of advanced biomaterials for the creation of sophisticated neuro-tissue analogues, showing that mimicking the in vivo tissue disposition and functions is a useful tool for the study of brain-related issues in normal and pathological states. In addition, the most common approach for developing new drug therapies is to carry out in vitro investigation before in vivo test, thus, it is increasingly important to develop valuable models that can predict the results of in vivo studies...

The use of genetically modified mesenchymal stem cells (MSCs) is a rapidly growing area of research targeting delivery of therapeutic factors for neuro-repair. Cells can be programmed to hypersecrete various growth/trophic factors such as brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF), and nerve growth factor (NGF) to promote regenerative neurite outgrowth. In addition to genetic modifications, MSCs can be subjected to transdifferentiation protocols to generate neural cell types to physically and biologically support nerve regeneration...

Several recent research findings indicate that schizophrenia (SCZ) may begin with an abnormal neuro-genesis from embryonic Neural Stem Cells (NSCs) and that this process may be particularly vulnerable to a number of genetic and/or environmental disturbances of early brain development. Since it is now well known that neurogenesis is not confined to the womb, but is a protracted process continuing in postnatal life well into adolescence and beyond, and since in the majority of subjects diagnosed with SCZ the first psychotic break occurs in late adolescence or early adulthood, the aim of our paper is to summarize the main findings supporting a possible link between changes in developmental postnatal neurogenesis and SCZ, with a specific focus on the critical period of adolescence and associated environmental risk factors...

Homeobox a1 (Hoxa1) is one of the most rapidly induced genes in ES cell differentiation and it is the earliest expressed Hox gene in the mouse embryo. In this study, we used genomic approaches to identify Hoxa1-bound regions during early stages of ES cell differentiation into the neuro-ectoderm. Within 2 h of retinoic acid treatment, Hoxa1 is rapidly recruited to target sites that are associated with genes involved in regulation of pluripotency, and these genes display early changes in expression. The pattern of occupancy of Hoxa1 is dynamic and changes over time...

DNA methylation of gene promoter regions represses transcription and is a mechanism via which environmental risk factors could affect cells during development in individuals at risk for schizophrenia. We investigated DNA methylation in patient-derived cells that might shed light on early development in schizophrenia. Induced pluripotent stem cells may reflect a "ground state" upon which developmental and environmental influences would be minimal. Olfactory neurosphere-derived cells are an adult-derived neuro-ectodermal stem cell modified by developmental and environmental influences...

A specialized quiescent population of hair follicle stem cells, residing in the hair follicle outer root sheath cells (ORSCs), has previously demonstrated pluripotency for differentiation into neural stem cells (NSCs). A previous study indicated that nestin‑positive hair follicle ORSCs are able to differentiate into neurons. However, little has been reported on the isolation of nestin‑negative human ORSCs and whether they can successfully differentiate into neurons in vitro. In the present study, nestin‑positive ORSCs were significantly reduced with a prolonged incubation time in vitro...

INTRODUCTION: Botulinum neurotoxins (BoNTs), the causative agents of botulism, are widely used as powerful bio-pharmaceuticals to treat neuro-muscular disorders. Due to the high potency and potential lethality of BoNTs, careful monitoring of the biologic activity of BoNT-based pharmaceuticals is required to ensure safe usage. For decades, the only approved method for potency determination of pharmaceutical BoNTs was the mouse bioassay (MBA), but in recent years improvements in cell-assay technologies have enabled MBA replacement by cell-based assays for specific product evaluations...

This review article addresses the biological factors that influence: (i) the acquisition of alcohol intake; (ii) the maintenance of chronic alcohol intake; and (iii) alcohol relapse-like drinking behavior in animals bred for their high-ethanol intake. Data from several rat strains/lines strongly suggest that catalase-mediated brain oxidation of ethanol into acetaldehyde is an absolute requirement (up 80%-95%) for rats to display ethanol's reinforcing effects and to initiate chronic ethanol intake. Acetaldehyde binds non-enzymatically to dopamine forming salsolinol, a compound that is self-administered...
