Glutamate toxicity has been implicated in the pathogenesis of various neurological diseases. Glial glutamate transporters play a key role in the regulation of extracellular glutamate levels in the brain by removing glutamate from the extracellular fluid. Since human blood platelets possess an...
A major aspect of understanding functions of the globus pallidus (GP) within the basal ganglia is the significance of its dopamine innervation. Here, we used in vivo-microdialysis in rats to characterize pallidal dopamine release in response to a number of physiological and pharmacological...
Amyloid-β accumulation in brains of Alzheimer's disease (AD) victims is accompanied by glial inflammatory reactions and preferential loss of cholinergic neurons. Therefore, the aim of this study was to find out whether proinflamatory cytokine interleukin 1β (IL1β) modifies effects of...
Role of central alpha2-adrenoceptors in the regulation of hypothalamic magnocellular cells was studied under hyperosmotic challenge elicited by hypertonic saline (HS). Rats pretreated with receptor agonist, xylazine (XYL), were injected intraperitoneally with different (low: 0.375, moderate:...
This paper served to evaluate the expression levels of subunits NR1, NR2A and NR2C which are implicated in neuronal plasticity events. A 50% (right half) 4 mm longitudinal resection of the spinal cord was done at the C5–C6 level with preservation of the anterior spinal artery. This was effected...
Superfused rat cerebral cortex slices were submitted to a continuous electrical (5 Hz) stimulation and treated with sodium azide (1–10 mM) in the presence of 2 mM 2-deoxyglucose (“chemical ischemia”). Presynaptic cholinergic activity, evaluated as acetylcholine release, was inhibited...
Ferroportin1 (FP1 or MTP1/IREG1), the product of the SLC40A1 gene, is a main iron export protein in mammals. Its mRNA contains an iron response element (IRE) in its 5′ untranslated region, but the way this gene is regulated by iron is still unclear. The existence of FP1 in the brain has been...
Oxidative stress has been implicated in acrolein cytotoxicity in various cell types, including mammalian spinal cord tissue. In this study we report that acrolein also decreases PC12 cell viability in a reactive oxygen species (ROS)-dependent manner. Specifically, acrolein-induced cell death,...
Divalent metal transporter 1 (DMT1) and transferrin receptor (TfR) might play a key role in non-transferrin-bound iron (NTBI) and transferrin-bound iron (Tf-Fe) uptake by neuronal cells. Recent studies demonstrated that nerve growth factor (NGF)-treated PC12 cells (the neuronal phenotype) have...
