Background/Aims: Vincristine (VCR) is a potent anticancer drug and neurotoxicity is one of its most important doselimiting toxicities. In this study, we investigated the effect of VCR by neurophysiological recordings and the tail flick test. To elucidate the underlying mechanism of action of VCR, expression of both N-methyl-D-aspartate (NMDA) receptor, an index of glutamate excitotoxity and cal...
Neurotoxicology considers that chemicals perturb neurological functions by interfering with the structure or function of neural pathways, circuits and systems. Using in vitro methods for neurotoxicity studies should include evaluation of specific targets for the functionalism of the nervous system and general cellular targets. In this review we present the neuronal characteristics of primary cu...
The involvement of calcium ions in mechanisms of ischemic brain injury has been suggested for several years. Our understanding of the role of intracellular Ca2+ as a trigger of acute neurotoxicity and in the induction of long lasting processes leading to necrotic and/or apoptotic postischemic delayed neuronal death or of compensatory, neuroprotective mechanisms has increased considerably. Still...
Glutamate, the most abundant excitatory transmitter in the brain can lead to neurotoxicity when not properly regulated. Excitotoxicity is a direct result of abnormal regulation of glutamate concentrations in the synapse, and is a common neurotoxic mediator associated with neurodegenerative disorders. It is well accepted that methamphetamine (METH), a potent central nervous stimulant with high a...
