Acid-sensing ion channels (ASICs) are ligand-gated cation channels that respond to acidic stimuli. They are expressed throughout the mammalian nervous system. Complex subunit combinations and lack of specific blockers of native receptors result in the difficulty of resolving the functions of ASICs. In this study, we showed that rat pheochromocytoma cells(More)
The genetic background and the pathogenesis of familial Parkinson's disease (PD) have not been fully elucidated. Two missense mutations in the alpha-synuclein gene, A30P and A53T, have been linked to familial PD. Increasing evidence suggests the involvement of alpha-synuclein, the dopamine transporter (DAT), and neurotoxins in the pathogenesis of PD, but(More)
Growing evidence suggests that dynein dysfunction may be implicated in the pathogenesis of neurodegeneration. It plays a central role in aggresome formation, the delivery of autophagosome to lysosome for fusion and degradation, which is a pro-survival mechanism essential for the bulk degradation of misfolded proteins and damaged organells. Previous studies(More)
Superoxide generated by human NADPH oxidase 5 (NOX5) is of growing importance for various physiological and pathological processes. The activity of NOX5 appears to be regulated by a self-contained Ca(2+) binding domain (CaBD). Recently Bánfi et al. suggest that the conformational change of CaBD upon Ca(2+) binding is essential for domain-domain interaction(More)
In this study, a priming Stroop paradigm was used to determine whether stereotype activation is unintentional. Priming conditions (priming/no-priming) and the relationship between priming and target (consistent/inconsistent/no-relation) were the independent variables; accuracy, reaction time and N400 amplitude were used as dependent variables. The reaction(More)
Paeoniflorin (PF) is the main active component extracted from the roots of Paeonialactiflora, a traditional Chinese medicine used for the treatment of neurodegenerative disorders, especially Parkinson’s disease (PD). The degeneration of dopaminergic (DA-) neurons in PD may be caused by pathological activation of acid-sensing ion channels (ASICs). Thus, we(More)
y These two authors contributed equally to this work. Autophagy dysfunction is implicated in the pathogenesis of Parkinson disease (PD). BECN1/Beclin 1 acts as a critical regulator of autophagy and other cellular processes; yet, little is known about the function and regulation of BECN1 in PD. In this study, we report that dopamine D2 and D3 receptor (DRD2(More)
Tumor necrosis factor-α (TNF) is increasingly implicated as a critical pro-inflammatory cytokine involved in chronic inflammation and neurodegeneration of Parkinson's disease (PD). However, the cellular and molecular events that lead to dopaminergic neuron degeneration are not fully understood. In this study, we demonstrated that microglia-released and(More)
BACKGROUND Neuroinflammation plays an important role in the pathogenesis of Parkinson's disease (PD), inducing and accelerating dopaminergic (DA) neuron loss. Autophagy, a critical mechanism for clearing misfolded or aggregated proteins such as α-synuclein (α-SYN), may affect DA neuron survival in the midbrain. However, whether autophagy contributes to(More)
