The dichotomy of NMDA receptor signaling.
The N-methyl-D-aspartate (NMDA) subtype of ionotropic glutamate receptors plays a Jekyll and Hyde role in the mammalian central nervous system. In pathological scenarios such as ischemia, Ca2+ influx through the NMDA receptor is a key mediator of cell death. However, physiological levels of NMDA-receptor activity can promote neuronal survival and resistance to trauma and play important roles in...
متن کاملO 17: Childhood Anti-NMDA Receptor Encephalitis
Anti N-methyl-D-aspartate receptor (NMDR) encephalitis has been recognized as the most frequent autoimmune encephalitis in children after acute demyelinating encephalomyelitis (ADEM).However due to the variable the variable clinical presentation, the paucity of specific finding on standard laboratory and radiological investigation remains under recognized. First discribed in 2005, most commonly...
متن کاملCaMKII translocation requires local NMDA receptor-mediated Ca2+ signaling.
Excitatory synaptic transmission and plasticity are critically modulated by N-methyl-D-aspartate receptors (NMDARs). Activation of NMDARs elevates intracellular Ca(2+) affecting several downstream signaling pathways that involve Ca(2+)/calmodulin-dependent protein kinase II (CaMKII). Importantly, NMDAR activation triggers CaMKII translocation to synaptic sites. NMDAR activation failed to induce...
متن کاملHyperdopaminergia and NMDA receptor hypofunction disrupt neural phase signaling.
Neural phase signaling has gained attention as a putative coding mechanism through which the brain binds the activity of neurons across distributed brain areas to generate thoughts, percepts, and behaviors. Neural phase signaling has been shown to play a role in various cognitive processes, and it has been suggested that altered phase signaling may play a role in mediating the cognitive deficit...
متن کاملNon-ionotropic signaling by the NMDA receptor: controversy and opportunity
Provocative emerging evidence suggests that the N-methyl-d-aspartate (NMDA) receptor can signal in the absence of ion flux through the receptor. This non-ionotropic signaling is thought to be due to agonist-induced conformational changes in the receptor, independently of channel opening. Non-ionotropic NMDA receptor signaling has been proposed to be sufficient to induce synaptic long-term depre...
