Background Anti-N-methyl- d-aspartate receptor (anti-NMDAR) encephalitis is an autoimmune neurological disorder that usually occurs as a paraneoplastic syndrome and is particularly associated with ovarian teratoma. Standard therapy for severe cases is not established and the prognosis in patients who do not respond to first-line treatment is poor. Case Report An 11-year-old boy complained ps...
OBJECTIVE To evaluate the presence of immunoglobulin A (IgA) subtype of anti-NMDA receptor (NMDAR) antibodies (IgA-NMDAR-Abs) in the CSF of patients with immunoglobulin G (IgG)-NMDAR-Ab encephalitis and to describe the potential association with a specific clinical pattern. METHODS The retrospective analysis for the presence of IgA-NMDAR-Abs in 94 CSF samples from patients with anti-NMDAR enc...
Glutamate and its receptor N-methyl-D-aspartate receptor (NMDAR) have been associated with cancer, although their functions are not fully understood. Herein, we implicate glutamate-driven NMDAR signaling in a mouse model of pancreatic neuroendocrine tumorigenesis (PNET) and in selected human cancers. NMDAR was upregulated at the periphery of PNET tumors, particularly invasive fronts. Moreover, ...
Stress and corticosteroids dynamically modulate the expression of synaptic plasticity at glutamatergic synapses in the developed brain. Together with alpha-amino-3-hydroxy-methyl-4-isoxazole propionic acid receptors (AMPAR), N-methyl-D-aspartate receptors (NMDAR) are critical mediators of synaptic function and are essential for the induction of many forms of synaptic plasticity. Regulation of N...
Abstract Objective To illustrate an unusual presentation of anti-n-methyl-D-aspartate-receptor (anti-NMDAR) encephalitis in a young adult male. Anti-NMDAR is autoimmune-mediated disorder with psychiatric and neurological features that can have lasting impact on cognition. Unique presentation, diagnosis, assessment are presented. Method Patient 28-year-old, Caucasian male history bipolar disorde...
Neurodegeneration is the pathophysiological basis for permanent neurological disabilities in multiple sclerosis (MS); thus neuroprotection is emerging as a therapeutic approach in MS research. Modulation of excitotoxicity by inhibition of NMDARs has been suggested for neuroprotection, but selective antagonisation of the NR2B subtype of these receptors, a subtype believed to play a more pivotal ...

N-methyl-D-aspartate receptors (NMDAR) have a recognized role in neuronal plasticity while their excessive activation results in excitotoxic death. Therefore, NMDAR antagonists are considered for neuroprotective interventions. However, there is also an emerging role of NMDAR in supporting neuronal survival. Thus, during CNS development, basal NMDAR activity suppresses neuronal apoptosis while m...
