Abstract

The prefrontal cortex (PFC) mediates higher-order cognitive and executive functions that subserve various complex, adaptable behaviors, such as cognitive flexibility, attention, and working memory. Deficits in these functions typify multiple neuropsychiatric disorders that are caused or exacerbated by exposure to psychological stress. Here we review recent evidence examining the effects of stress on executive and cognitive functions in rodents and discuss an emerging body of evidence that implicates the N-methyl-D-aspartate receptor (NMDAR) as a potentially critical molecular mechanism mediating these effects. Future work in this area could open up new avenues for developing pharmacotherapies for ameliorating cognitive dysfunction in neuropsychiatric disease.

Activation of N-methyl-D-aspartate receptor regulates insulin sensitivity and lipid metabolism

Xiao-Ting Huang, Jun-Xiao Yang, Zun Wang, Chen-Yu Zhang, Zi-Qiang Luo, Wei Liu, Si-Yuan Tang

Summary: The study highlights the role of the glutamate/NMDAR axis in obesity-related metabolic syndrome, with evidence showing that targeting NMDAR can be a promising therapeutic strategy. In obese mice, increased glutamate levels and blockade of NMDAR by Memantine improved insulin sensitivity and reduced hepatic steatosis, while NMDA treatment induced obesity and metabolic disorders. In vitro studies demonstrated that NMDAR activation promoted lipid accumulation and impaired fatty acid oxidation through PPARa signaling, suggesting a potential mechanism for NMDAR-mediated metabolic syndrome in obesity.

Silberbauer, Jakob Unterholzner, Christoph Wotawa, Ahmed Haider, Hazem Ahmed, Roger Schibli, Thomas Mindt, Markus Mitterhauser, Wolfgang Wadsak, Andreas Hahn, Rupert Lanzenberger, Marcus Hacker, Simon M. Ametamey

Summary: This study reports on the performance characteristics of (R)-C-11-Me-NB1, a radioligand used to map GluN2B-enriched NMDARs in the human brain. The radioligand demonstrated high and heterogeneous uptake and a high test-retest reliability. It shows promise in deepening our understanding of the role of GluN2B-containing NMDARs in neurodegenerative and neuropsychiatric diseases such Alzheimer's disease and major depression.

Parvalbumin-Positive Interneurons in the Medial Prefrontal Cortex Regulate Stress-Induced Fear Extinction Impairments in Male and Female Rats

Annalise N. Binette, Jianfeng Liu, Hugo Bayer, Kennedi L. Crayton, Laila Melissari, Samantha O. Sweck, Stephen Maren

Summary: Stress has a significant impact on fear extinction and affects the activity of PV interneurons in the mPFC. PV interneurons regulate extinction learning under stress in a sex-dependent manner, and this effect is mediated by amygdaloprefrontal projections.

N-Methyl-D-Aspartate (NMDA)-Type Glutamate Receptors and Demyelinating Disorders: A Neuroimmune Perspective

Amir Parsa Abhari, Masoud Etemadifar, Niloufar Yazdanpanah, Nima Rezaei

Summary: N-methyl-D-aspartate receptors (NMDARs) play a crucial role in regulating physiological processes in the brain and nervous system. Dysfunction of NMDARs can contribute to various pathologies, including cell death and brain dysfunction. Research has shown the significant involvement of NMDARs in demyelinating disorders and anti-NMDAR encephalitis.

Effects of Quinolinate-Induced Lesion of the Medial Prefrontal Cortex on Prefrontal and Striatal Concentrations of d-Serine in the Rat

Asami Umino, Hisayuki Iwama, Masakazu Umino, Dai Shimazu, Yuji Kiuchi, Toru Nishikawa

Summary: d-Serine has been shown to play an important role in brain functions through its interaction with NMDAR. The selective destruction of neuronal cell bodies in the medial prefrontal cortex results in a significant decrease in tissue and extracellular d-serine concentrations, suggesting that the prefrontal cortical region contains substantial amounts of d-serine. The reduction in GABA levels in the prefrontal cortex supports the perikarya-selective nature of the lesion.

Summary: The study demonstrates that NMDAR blockade alleviates D-serine-induced renal injury, possibly through the involvement of NOX4-mediated oxidative stress. These findings have important implications for preventing acute renal injury caused by D-serine.

Levodopa-induced dyskinesia: interplay between the N-methyl-D-aspartic acid receptor and neuroinflammation

Fanshi Zhang, Mei Liu, Jinmei Tuo, Li Zhang, Jun Zhang, Changyin Yu, Zucai Xu

Summary: This article reviews how neuroinflammation mediates the development of levodopa-induced dyskinesia (LID) through the regulation of NMDA receptors. It also evaluates the potential of common anti-inflammatory drugs and NMDA receptor antagonists to mitigate the development of LID by regulating central neuroinflammation, providing a new theoretical basis for finding new therapeutic targets for LID.

N-Methyl-D-Aspartate (NMDA) Receptors in the Prelimbic Cortex Are Required for Short- and Long-Term Memory Formation in Trace Fear Conditioning

Eui-Ho Park, Nam-Soo Kim, Yeon-Kyung Lee, June-Seek Choi

Summary: Accumulating evidence suggests that the medial prefrontal cortex (mPFC) plays a crucial role in the acquisition of fear memory during trace fear conditioning. Specifically, the prelimbic (PL) subregion within the mPFC is involved in short- and long-term trace fear memory formation. Furthermore, NMDA receptor-mediated neurotransmission in PL is required for the acquisition of trace fear memory.

Spatiotemporal Alterations in Working Memory-Related Beta Band Neuromagnetic Activity of Patients With Schizophrenia On and Off Antipsychotic Medication: Investigation With MEG

Daniel Y. Rubinstein, Daniel P. Eisenberg, Frederick W. Carver, Tom Holroyd, Jose A. Apud, Richard Coppola, Karen F. Berman

Summary: This study used magnetoencephalography to investigate working memory-related beta band activity in schizophrenic patients compared to healthy controls. The results showed altered beta band activation in medication-free patients, which were largely observed in prefrontal, parietal, and visual cortices. Antipsychotic medication altered the neural responses in these regions to resemble those of controls.

Human Placenta Derived Mesenchymal Stem Cells Transplantation Reducing Cellular Apoptosis in Hypoxic-Ischemic Neonatal Rats by Down-Regulating Semaphorin 3A/Neuropilin-1

Yang He, Jun Tang, Meng Zhang, Junjie Ying, Dezhi Mu

Summary: This study investigated the protective effects and mechanisms of human placenta derived mesenchymal stem cells (hPMSCs) transplantation in a rat model of hypoxic-ischemic encephalopathy (HIE). The results showed that hPMSCs transplantation reduced apoptosis and improved long-term neurological prognosis. Furthermore, the downregulation of Sema 3A/NRP-1 expression and activation of the PI3K/Akt/mTOR signaling pathway played a key role in the protective effects of hPMSCs.

Probing the Neurophysiology of Temporal Sensitivity in the Somatosensory System Using the Mismatch Negativity (MMN) Sensory Memory Paradigm

Emily L. Isenstein, Edward G. Freedman, Jiayi Xu, Ian A. DeAndrea-Lazarus, John J. Foxe

Summary: This study evaluated electrophysiological discrimination of parametric somatosensory stimuli in healthy young adults to understand how the brain processes the duration of tactile information. The results showed that participants did not electrophysiologically discriminate between 100 and 115 ms, but they exhibited distinct electrophysiological responses when the deviant stimuli were 130, 145, and 160 ms. These findings contribute to a better understanding of tactile sensitivity in different clinical conditions.

Correlation Between Cued Fear Memory Retrieval and Oscillatory Network Inhibition in the Amygdala Is Disrupted by Acute REM Sleep Deprivation

Miki Hashizume, Rina Ito, Rie Suge, Yasushi Hojo, Gen Murakami, Takayuki Murakoshi

Summary: The basolateral amygdaloid complex (BLA) is closely involved in the formation of emotional memories, including both aversive memory and contextual fear memory. Acute sleep deprivation (SD) disrupts the acquisition of tone-associated fear memory in juvenile rats, but has no significant effect on contextual fear memory. Slow network oscillation in the amygdala contributes to the formation of amygdala-dependent fear memory in relation to sleep.

Enhanced Gasdermin-E-mediated Pyroptosis in Alzheimer's Disease

Qunxian Wang, Shipeng Guo, Dongjie Hu, Xiangjun Dong, Zijun Meng, Yanshuang Jiang, Zijuan Feng, Weihui Zhou, Weihong Song

Summary: GSDME plays a crucial role in the pathogenesis of Alzheimer's disease by regulating the switch from apoptosis to pyroptosis and participating in neuroinflammatory response. Knockdown of GSDME has been shown to improve cognitive impairments, indicating that GSDME could be a therapeutic target for Alzheimer's disease.
