HMGB1 Mediates Inflammation-Induced DMT1 Increase and Dopaminergic Neurodegeneration in the Early Stage of Parkinsonism
Both neuroinflammation and iron accumulation play roles in the pathogenesis of Parkinson’s disease (PD). However, whether inflammation induces iron dyshomeostasis in dopaminergic neurons at an early stage of P...

Different Characteristics of Hepcidin Expression in IL-6+/+ and IL-6−/− Neurons and Astrocytes Treated with Lipopolysaccharides
A region-specific regulation of inflammation on the expression hepcidin in the brain has been demonstrated, however, it remains unknown whether there is also a cell-specific regulation of inflammation on hepci...

Neuroprotective Effects of Lycium barbarum Polysaccharide on Focal Cerebral Ischemic Injury in Mice
Increasing evidence demonstrates inflammation contributes to neuronal death following cerebral ischemia. Lycium barbarum polysaccharide (LBP) has been reported to prevent scopolamine-induced cognitive and memory ...

Expression of Iron Transporters and Pathological Hallmarks of Parkinson’s and Alzheimer’s Diseases in the Brain of Young, Adult, and Aged Rats
Iron accumulates progressively in the brain with age; however, the cause is unknown. We hypothesized that iron accumulation may be associated with the age-induced changes in the expression of iron metabolism p...

CX3CL1/CX3CR1 Axis Plays a Key Role in Ischemia-Induced Oligodendrocyte Injury via p38MAPK Signaling Pathway
Based on current knowledge on the role of the CX3CL1/CX3CR1 axis in the regulation of microglial activation and on the involvement of activated microglia in damaging oligodendrocytes, we hypothesized that CX3C...

Hepcidin Suppresses Brain Iron Accumulation by Downregulating Iron Transport Proteins in Iron-Overloaded Rats
Iron accumulates progressively in the brain with age, and iron-induced oxidative stress has been considered as one of the initial causes for Alzheimer’s disease (AD) and Parkinson’s disease (PD). Based on the ...

Lipopolysaccharides Upregulate Hepcidin in Neuron via Microglia and the IL-6/STAT3 Signaling Pathway
Neuroinflammation is closely related to brain iron homeostasis. Our previous study demonstrated that lipopolysaccharides (LPS) can regulate expression of iron-regulatory peptide hepcidin; however, the mechanis...

Iron and Intracerebral Hemorrhage: From Mechanism to Translation
Intracerebral hemorrhage (ICH) is a leading cause of morbidity and mortality around the world. Currently, there is no effective medical treatment available to improve functional outcomes in patients with ICH d...

Angiotensin II Inhibits Iron Uptake and Release in Cultured Neurons
Based on the well-confirmed roles of angiotensin II (ANGII) in iron transport of peripheral organs and cells, the causative link of excess brain iron with and the involvement of ANGII in neurodegenerative diso...

A Synergistic Role of Hyperthermic and Pharmacological Preconditioning to Protect Astrocytes Against Ischemia/Reperfusion Injury
Recent studies provide solid evidence for the importance to delineate the co-relationship between preconditioning stimuli and therapeutic efficacy of drugs commonly used in clinic. However, very little is know...

Activation of Group III Metabotropic Glutamate Receptor Reduces Intracellular Calcium in β-Amyloid Peptide [31–35]-Treated Cortical Neurons
It is unknown whether amyloid beta-protein 31–35 (Aβ[31–35]) has effects similar to Aβ[1–40] and Aβ[25–35] on the intracellular calcium ([Ca2+]i) to induce a disruption of calcium homeostasis. In this study, we i...

Nerve Growth Factor Protects the Cortical Neurons from Chemical Hypoxia-induced Injury
Previous studies showed that nerve growth factor (NGF) exerts protective effects on cultured neurons against various kinds of damage. However, a recent publication reported that exposure of NGF-treated PC12 ce...

Protection against hydrogen peroxide-induced injury by Z-ligustilide in PC12 cells
Z-ligustilide (Z-LIG) is the primary lipophilic compound of the Chinese medicine Danggui (Radix Angelica sinensis). Previous studies demonstrated that Z-LIG had significant neuroprotective potential in both trans...

Ginkgolides protect primary cortical neurons from potassium cyanide-induced hypoxic injury
In this study, we investigated the effects of ginkgolides (Gins A, B, C and J), the main constituent of the non-flavone fraction of EGb 761, on hypoxic injury induced by potassium cyanide (KCN) in primary cort...
