Abstract Background Synaptic damage and glutamate excitotoxicity have been implicated in the pathogenesis of vascular dementia (VD). Clathrin, RAB5B N -methyl- d -aspartic acid receptor 1 (NMDAR1) proteins play a vital role endocytosis synaptic vesicles neurons over accumulation. Previous researches confirmed that Shenzhi Jiannao (SZJN) formula has an anti-apoptotic neuroprotective effect VD, b...
The cytotoxic action of quartz (DQ12) particles on cultures of rat peritoneal macrophages, as estimated by the inhibition of the TTC-reductase activity, is considerably reduced by preincubation with glutamic acid and by adding sodium glutamate (15 mg/ml) to the drinking water of the rats donating the macrophages. This increase in macrophage resistance under the influence of glutamate is the mos...
Ifenprodil-induced protection against glutamate cytotoxicity in primary culture of cortical neurons.
Protective effects of adenosine against glutamate-induced cytotoxicity in cultured cortical neurons.
OBJECTIVE Chlorpyrifos (CPF) is a neurotoxic organophosphorus (OP) insecticide. Its mechanism of action includes oxidative stress, excitotoxicity, and inhibition of the acetylcholinesterase enzyme (AChE). The aim of the present study is to investigate CPF toxicity in mature and immature cerebellar granule neurons (CGNs), as well as its effect on glutamate induced excitotoxicity. MATERIALS AND...
BACKGROUND Glutamate (an endogenous excitatory neurotransmitter) at high concentrations contributes to the development of neurodegenerative diseases. Aronia melanocarpa (A. melanocarpa) berries contain anthocyanins and have high antioxidant activities. In this study, we evaluated whether A. melanocarpa berries could protect neuronal cells against glutamate-induced oxidative stress. METHOD A. ...
Oxidative stress plays an important role in neuronal cell death associated with many different neurodegenerative conditions such as cerebral ischemia and Parkinson's disease. Elevated levels of glutamate are thought to be responsible for CNS disorders through various mechanisms causing oxidative stress induced by a nonreceptor-mediated oxidative pathway which blocks cystine uptake and results i...
We have demonstrated that addition of L-glutamate in millimolar amounts to a culture of C6 glioma cells induced cell death within 24 h. The glutamate-induced toxicity in the C6 glioma cells was completely suppressed by adding L-cystine (0.4-1.0 mM), while the C6 cells degenerated in L-cystine-deprived culture medium. Kinetic studies of [35S]cystine and [3H]glutamate uptake showed that cystine c...
