NMDA receptors (NMDARs) mediate ischemic brain damage, for which interactions between the C termini of NR2 subunits and PDZ domain proteins within the NMDAR signaling complex (NSC) are emerging therapeutic targets. However, expression of NMDARs in a non-neuronal context, lacking many NSC components, can still induce cell death. Moreover, it is unclear whether targeting the NSC will impair NMDAR...

N-methyl-D-aspartate (NMDA) receptor-mediated excitotoxicity is one of the major causes for neuronal cell death during cerebral ischemic insult. Previously, we reported that the final product of lipid membrane peroxidation 4-hydroxy-2E-nonenal (HNE) synergistically increased NMDA receptor-mediated excitotoxicity (J Neurochem., 2006). In this study, we investigated the mechanism involved in the ...

Neurodegenerative diseases contain Multiple Sclerosis (MS), Alzheimer’s disease (AD) and Parkinson’s disease (PD), are characterized by neuronal death and neuronal degeneration in specific regions of the central nervous system (CNS). Microglia are the basic immune brain cells and play a role in homeostasis after inflammation challenge. Microglia involves in Neurodegenerative disease...

Many neurons in Alzheimer's disease (AD) exhibit terminal deoxynucleotidyl transferase (TdT) labeling for DNA strand breaks with a distribution suggestive of apoptosis. We have shown previously that immunoreactivity for c-Jun is elevated in AD and found in association with neuronal pathology. In addition, cultured neurons undergoing beta-amyloid-mediated apoptosis exhibit a selective and prolon...

We show that the unavoidable increase in neuronal response latency to ongoing stimulation serves as a nonuniform gradual stretching of neuronal circuit delay loops and emerges as an essential mechanism in the formation of various types of neuronal timers. Synchronization emerges as a transient phenomenon without predefined precise matched synaptic delays. These findings are described in an expe...

Objective: Malformations of cortical development (MCD) are rare central nervous system abnormalities that caused by disruption normal stages, including neural cell proliferation, type differentiation, neuronal migration, and final positioning. It has different phenotypic presentations which largely depend on the underlying cause disorder is associated with other neurologic systemic disorders. M...

BACKGROUND AND PURPOSE Transient ischemic attacks have long been regarded as a risk factor for the incidence of stroke but may reduce the severity of stroke by inducing ischemic tolerance. The present objective was to develop an ischemic preconditioning (IPC) model of delayed tolerance in the mouse based on repetitive, transient middle cerebral artery occlusion (MCAO). METHODS Mice anesthetiz...
