Abstract
Acetyl-11-keto-beta-boswellic acid (AKBA), a potent anti-inflammatory compound purified from Boswellia species, was investigated in a preclinical study for its potential in preventing and treating non-alcoholic fatty liver disease (NAFLD), the most common chronic inflammatory liver disorder. The study involved thirty-six male Wistar rats, equally divided into prevention and treatment groups. In the prevention group, rats were given a high fructose diet (HFrD) and treated with AKBA for 6 weeks, while in the treatment group, rats were fed HFrD for 6 weeks and then given a normal diet with AKBA for 2 weeks. At the end of the study, various parameters were analyzed including liver tissues and serum levels of insulin, leptin, adiponectin, monocyte chemoattractant protein-1 (MCP-1), transforming growth factor beta (TGF-β), interferon gamma (INF-ϒ), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-α). Additionally, the expression levels of genes related to the inflammasome complex and peroxisome proliferator-activated receptor gamma (PPAR-ϒ), as well as the levels of phosphorylated and non-phosphorylated AMP-activated protein kinase alpha-1 (AMPK-α1) protein, were measured. The results showed that AKBA improved NAFLD-related serum parameters and inflammatory markers and suppressed PPAR-ϒ and inflammasome complex-related genes involved in hepatic steatosis in both groups. Additionally, AKBA prevented the reduction of the active and inactive forms of AMPK-α1 in the prevention group, which is a cellular energy regulator that helps suppress NAFLD progression. In conclusion, AKBA has a beneficial effect on preventing and avoiding the progression of NAFLD by preserving lipid metabolism, improving hepatic steatosis, and suppressing liver inflammation.

Abstract
Oligodendrocyte (OL) damage and death are prominent features of multiple sclerosis (MS) pathology, yet mechanisms contributing to OL loss are incompletely understood. Dysfunctional RNA binding proteins (RBPs), hallmarked by nucleocytoplasmic mislocalization and altered expression, have been shown to result in cell loss in neurologic diseases, including in MS. Since we previously observed that the RBP heterogeneous nuclear ribonucleoprotein A1 (hnRNP A1) was dysfunctional in neurons in MS, we hypothesized that it might also contribute to OL pathology in MS and relevant models. We discovered that hnRNP A1 dysfunction is characteristic of OLs in MS brains. These findings were recapitulated in the experimental autoimmune encephalomyelitis (EAE) mouse model of MS, where hnRNP A1 dysfunction was characteristic of OLs, including oligodendrocyte precursor cells and mature OLs in which hnRNP A1 dysfunction correlated with demyelination. We also found that hnRNP A1 dysfunction was induced by IFNγ, indicating that inflammation influences hnRNP A1 function. To fully understand the effects of hnRNP A1 dysfunction on OLs, we performed siRNA knockdown of hnRNP A1, followed by RNA sequencing. RNA sequencing detected over 4000 differentially expressed transcripts revealing alterations to RNA metabolism, cell morphology, and programmed cell death pathways. We confirmed that hnRNP A1 knockdown was detrimental to OLs and induced apoptosis and necroptosis. Together, these data demonstrate a critical role for hnRNP A1 in proper OL functioning and survival and suggest a potential mechanism of OL damage and death in MS that involves hnRNP A1 dysfunction.

Abstract
Traumatic brain injury (TBI) can result in permanent brain function impairment due to the poor regenerative ability of neural tissue. Tissue engineering has appeared as a promising approach to promote nerve regeneration and to ameliorate brain damage. The present study was designed to investigate the effect of transplantation of the human meningioma stem-like cells (hMgSCs) seeded in a promising three-dimensional scaffold (RADA4GGSIKVAV; R-GSIK) on the functional recovery of the brain and neuroinflammatory responses following TBI in rats. After induction of TBI, hMgSCs seeded in R-GSIK was transplanted within the injury site and its effect was compared to several control groups. Application of hMgSCs with R-GSIK improved functional recovery after TBI. A significant higher number of hMgSCs was observed in the brain when transplanted with R-GSIK scaffold compared to the control groups. Application of hMgSCs seeded in R-GSIK significantly decreased the lesion volume, reactive gliosis, and apoptosis at the injury site. Furthermore, treatment with hMgSCs seeded in R-GSIK significantly inhibited the expression of Toll-like receptor 4 and its downstream signaling molecules, including interleukin-1β and tumor necrosis factor. These data revealed the potential for hMgSCs seeded in R-GSIK to improve the functional recovery of the brain after TBI; possibly via amelioration of inflammatory responses. STATEMENT OF SIGNIFICANCE: Tissue engineered scaffolds that mimic the natural extracellular matrix of the brain may modulate stem cell fate and contribute to tissue repair following traumatic brain injury (TBI). Among several scaffolds, self-assembly peptide nanofiber scaffolds markedly promotes cellular behaviors, including cell survival and differentiation. We developed a novel three-dimensional scaffold (RADA16GGSIKVAV; R-GSIK). Transplantation of the human meningioma stem-like cells seeded in R-GSIK in an animal model of TBI significantly improved functional recovery of the brain, possibly via enhancement of stem cell survival as well as reduction of the lesion volume, inflammatory process, and reactive gliosis at the injury site. R-GSIK is a suitable microenvironment for human stem cells and could be a potential biomaterial for the reconstruction of the injured brain after TBI.

Abstract
The use of neurotrophic factors is considered to be a novel therapeutic approach for restoring and/or maintaining neurological function in neurodegenerative disorders, such as multiple sclerosis (MS). Various studies have shown that conditioned medium produced by oligodendrocyte (OL-CM) contain a variety of neurotrophic factors. Here, we investigated the restorative effects of OL-CM, collected from oligodendrocytes cultured in a self-assembling peptide hydrogels scaffold (PuraMatrix), in experimental autoimmune encephalomyelitis (EAE) mouse model. Neural stem/progenitor cells, isolated from the embryonic mouse brain, were cultured and differentiated into oligodendrocyte. Cell viability and proliferation of oligodendrocytes were assessed by live/dead and MTT assays. Motor functions, myelination, cell infiltration, gliosis, and inflammatory process were assessed in EAE mice after intracranial injection of OL-CM at different concentrations. Application of OL-CM improved clinical score and neurological function in EAE mice and reduced the inflammatory cell infiltration and demyelination. Furthermore, administration of OL-CM reduced the expression of pro-inflammatory cytokines and suppressed the activation of NLRP3-inflammasome complex in EAE mice. These data suggest the potential therapeutic effect of OL-CM for MS treatment.

Abstract
Traumatic brain injury (TBI) is a disruption in the brain functions following a head trauma. Cell therapy may provide a promising treatment for TBI. Among different cell types, human neural stem cells cultured in self-assembling peptide scaffolds have been suggested as a potential novel method for cell replacement treatment after TBI. In the present study, we accessed the effects of human neural stem/progenitor cells (hNS/PCs) derived from epileptic human brain and human adipose-derived stromal/stem cells (hADSCs) seeded in PuraMatrix hydrogel (PM) on brain function after TBI in an animal model of brain injury. hNS/PCs were isolated from patients with medically intractable epilepsy undergone epilepsy surgery. hNS/PCs and hADSCs have the potential for proliferation and differentiation into both neuronal and glial lineages. Assessment of the growth characteristics of hNS/PCs and hADSCs revealed that the hNS/PCs doubling time was significantly longer and the growth rate was lower than hADSCs. Transplantation of hNS/PCs and hADSCs seeded in PM improved functional recovery, decreased lesion volume, inhibited neuroinflammation, and reduced the reactive gliosis at the injury site. The data suggest the transplantation of hNS/PCs or hADSCs cultured in PM as a promising treatment option for cell replacement therapy in TBI.

Abstract
OBJECTIVE Arsenic, an environmental pollutant, decreases neuronal migration as well as cellular maturation and inhibits the proliferation of neural progenitor cells. Curcumin has been described as an antioxidant and neuroprotective agent with strong therapeutic potential in some neurological disorders. Human adipose-derived stem cells (hADSCs), a source of multipotent stem cells, can self-renew and differentiate into neural cells. The aim of the present study was to investigate the preventive effect of curcumin against arsenic toxic effects on the viability, telomerase activity, and apoptosis of neural stem/progenitor cells (NSPCs) derived from hADSCs. MATERIALS AND METHODS The characteristics of human adipose tissue were identified by immunocytochemistry for surface markers namely, CD105, CD73, and CD90. Using neurosphere assay, hADSCs were differentiated into neuronal cells. To characterize neural cells, expression of nestin, SOX2, MAP2, and GFAP were assessed by immunocytochemistry. Cytotoxicity and viability of NSPCs were evaluated by MTT assay. Reactive oxygen species (ROS) generated by arsenic exposure, were measured and caspase 3/7 activity and caspase-3 processing as well as the telomerase activity were determined. RESULTS The isolated hADSCs positively expressed CD105, CD73, and CD90. Nestin, Sox2, GFAP, and MAP2 were expressed in the neurospheres derived from hADSCs. Curcumin/arsenic co-treatment significantly increased telomerase activity of NSPCs compared to arsenic group. Furthermore, curcumin significantly reduced arsenic-induced apoptosis (via inactivation of caspases) as well as arsenic-associated ROS generation. CONCLUSION Our findings revealed that curcumin has the potential to prevent harmful effects of arsenic on neurogenesis.

Abstract
Repetitive cortical spreading depression (CSD) can lead to cell death in immature brain tissue. Caspases are involved in neuronal cell death in several CSD-related neurological disorders, such as stroke and epilepsy. Yet, whether repetitive CSD itself can induce caspase activation in adult or juvenile tissue remains unknown. Inducing repetitive CSD in somatosensory cortices of juvenile and adult rats in vivo, we thus aimed to investigate the effect of repetitive CSD on the expression caspase-3, caspase-8, caspase-9, and caspase-12 in different brain regions using immunohistochemistry and western blotting techniques. Higher numbers of dark neurons and TUNEL-positive cells were observed in the hippocampal CA1 and CA3 regions as well as in the entorhinal and somatosensory cortices after CSD in juvenile rats. This was accompanied by higher expressions of caspase-3, caspase-8, and caspase-9. Caspase-12 levels remained unchanged after CSD, suggesting that endoplasmic reticulum stress is not involved in CSD-triggered apoptosis. Changes in caspase expression were paralleled by a decrease of procaspase-3, procaspase-8, and procaspase-9 in juvenile rat brain tissue subjected to CSD. In contrast, repetitive CSD in adult rats did not result in the upregulation of caspase signaling. Our data points to a maturation-dependent vulnerability of brain tissue to repetitive CSD with a higher degree of apoptotic damage and caspase upregulation observed in juvenile tissue. Findings suggest a key role of caspase signaling in CSD-induced cell death in the immature brain. This implies that anti-apoptotic treatment may prevent CSD-related functional deficits in the immature brain.
