Maternal obesity is known to increase the risk of psychiatric disorders, such as anxiety, depression, schizophrenia and autism spectrum disorder in the offspring. While preventive measures are well-documented, practical approaches for addressing the damages once they are already established are limited. We have recently demonstrated the interplay between maternal obesity and treatment with cannabidiol (CBD) on neuroinflammation and peripheral metabolic disturbances during adolescence, however, it is known that both factors tend to vary throughout life.

Gulf War Illness (GWI) has been consistently linked to exposure to pyridostigmine (PB), N,N-Diethyl-meta-toluamide (DEET), permethrin (PER), and traces of sarin. In this study, diisopropylfluorophosphate (DFP, sarin surrogate) and the GWI-related chemicals were found to reduce the number of functionally active neurons in rat hippocampal slices. These findings confirm a link between GWI neurotoxicants and N-Methyl-D-Aspartate (NMDA)-mediated excitotoxicity, which was successfully reversed by Edelfosine (a phospholipase Cβ (PLCβ3) inhibitor) and Flupirtine (a Kv7 channel agonist).

Hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis during chronic stress is essential for depression neurobiology. As the latest member of the RFamide peptide family in mammals, pyroglutamylated RFamide peptide (QRFP) is closely implicated in neuroendocrine maintenance by activating G-protein-coupled receptor 103 (GPR103). We hypothesized that QRFP and GPR103 might contribute to chronic stress-induced depression by promoting corticotropin-releasing hormone (CRH) release from neurons in the paraventricular nucleus (PVN), and various methods were employed in this study, with male C57BL/6J mice adopted as the experimental subjects.

Histamine, a neurotransmitter, plays a predominant role in maintaining wakefulness. Furthermore, our previous studies showed that histamine N-methyltransferase (HNMT), a histamine-metabolizing enzyme, is important for regulating brain histamine concentration. However, the effects of pharmacological HNMT inhibition on mouse behavior, including the sleep-wake cycle and cataplexy, in a mouse model of narcolepsy have not yet been investigated.

Prelimbic cortex perineuronal net expression and social behavior: Impact of adolescent intermittent ethanol exposure.

Neuropharmacology

January 2025

Neurobiology of Adolescent Drinking in Adulthood Consortium, Center for Development and Behavioral Neuroscience, Department of Psychology, Binghamton University, Binghamton, NY, 13902-6000, USA. Electronic address:

Adolescent intermittent ethanol (AIE) exposure in rats leads to social deficits. Parvalbumin (PV) expressing fast-spiking interneurons in the prelimbic cortex (PrL) contribute to social behavior, and perineuronal nets (PNNs) within the PrL preferentially encompass and regulate PV interneurons. AIE exposure increases PNNs, but it is unknown if this upregulation contributes to AIE-induced social impairments.

Adv Sci (Weinh)

December 2024

Key Laboratory of Neuropharmacology and Translational Medicine of Zhejiang Province, School of Pharmaceutical Sciences, Zhejiang Chinese Medical University, Hangzhou, Zhejiang, 310053, China.

Enriched environment (EE), characterized by multi-sensory stimulation, represents a non-invasive alternative for alleviating epileptic seizures. However, the mechanism by which EE exerts its therapeutic impact remains incompletely understood. Here, it is elucidated that EE mitigates seizure susceptibility through the augmentation of adult neurogenesis within the entorhinal cortex (EC) circuit.

G protein-gated inwardly rectifying K+ (GIRK/Kir3) channels: Molecular, cellular, and subcellular diversity.

Histol Histopathol

September 2024

Synaptic Structure Laboratory, Instituto de Biomedicina de la UCLM (IB-UCLM), Departamento de Ciencias Médicas, Facultad de Medicina, Universidad Castilla-La Mancha, Albacete, Spain.

G protein-gated inwardly rectifying K (GIRK/K3) channels are mainly expressed in excitable cells such as neurons and atrial myocytes, where they can respond to a wide variety of neurotransmitters. Four GIRK subunits have been found in mammals (GIRK1-4) and act as downstream targets for various Gαi/o-linked G protein-coupled receptors (GPCRs). Activation of GIRK channels produces a postsynaptic efflux of potassium from the cell, responsible for hyperpolarization/inhibition of the neuron.

Article Synopsis
  • Anxiety is an emotional response marked by worry and tension, potentially linked to the downregulation of TNRC6A in the brain's prefrontal cortex (PFC) following stress.
  • Inhibition of TNRC6A increases anxious behaviors in mice, as it maintains the stability of miR-21-3p, a microRNA that can mitigate anxiety when present in higher levels.
  • The study highlights a new molecular mechanism, showing that low TNRC6A levels reduce miR-21-3p stability, leading to increased corticotropin-releasing factor (CRF) levels and consequently, heightened anxiety-like behaviors.

Transformer-based classification of visceral pain-related local field potential patterns in the brain.

Sci Rep

October 2024

Department of Pharmacology, Graduate School of Pharmaceutical Sciences, Tohoku University, 6-3 Aramaki-Aoba, Aoba-Ku, Sendai, 980-8578, Japan.

Neuronal ensemble activity entrained by local field potential (LFP) patterns underlies a variety of brain functions, including emotion, cognition, and pain perception. Recent advances in machine learning approaches may enable more effective methods for analyzing LFP patterns across multiple brain areas than conventional time-frequency analysis. In this study, we tested the performance of two machine learning algorithms, AlexNet and the Transformer models, to classify LFP patterns in eight pain-related brain regions before and during acetic acid-induced visceral pain behaviors.

Receptor-interacting serine/threonine protein kinase 2 (RIPK2) is a kinase that plays an essential role in the modulation of innate and adaptive immune responses. As a downstream signaling molecule for nucleotide-binding oligomerization domain 1 (NOD1), NOD2, and Toll-like receptors (TLRs), it is implicated in the signaling triggered by recognition of microbe-associated molecular patterns by NOD1/2 and TLRs. Upon activation of these innate immune receptors, RIPK2 mediates the release of pro-inflammatory factors by activating mitogen-activated protein kinases (MAPKs) and nuclear factor-kappa B (NF-κB).

From a neuroscientific point of view, one of the unique archetypes of substance use disorders is its road to relapse, in which the reward system plays a crucial role. Studies on the neurobiology of substance use disorders have highlighted the central role of a protein belonging to the Fos family of transcription factors, ΔFosB. Relying on the roles ΔFosB plays in the pathophysiology of substance use disorders, we endeavour to present some evidence demonstrating that -acetylcysteine, a low-cost and well-tolerated over-the-counter medicine, may influence the downstream pathway of ΔFosB, thereby serving as a treatment strategy to mitigate the risk of relapse in cases of substance use.
