Summary: Glutamate (GLU) and gamma-aminobutyric acid (GABA) play crucial roles in signal transmission in the brain. Imbalances in GLU-GABA homeostasis are linked to brain disorders, and a silicon multifunctional biosensor microarray probe has been developed for real-time simultaneous GLU-GABA detection with high sensitivity and selectivity in vivo.

Summary: This study observed the characteristics of gut microbiota, lipid metabolism, and neurotransmitters in depressed mice and identified the relationship between gut microbiota and depression. The results showed significant differences in gut microbiota and metabolic signatures between depressed mice and control mice, and suggested that lipid metabolism might play a crucial role in the link between gut microbiota and depression.

Summary: Baruch Kanner and the author have parallel careers in investigating neurotransmitter transporters, collaborating and competing at various points but always learning from each other. This commentary focuses on interactions between the Kanner and Rudnick laboratories, specifically on transporters in the Neurotransmitter: Sodium Symporter (NSS) family of amino acid and amine transporters, with a key emphasis on the mechanism of chloride ion activation and transport driving.

Summary: This study aimed to investigate the changes in retinal neurotransmitters and the role of the dopamine D2 receptor (D2R) pathway in regulating myopic refractive state. The results showed that after forced occlusion for 4 weeks, dopamine (DA) and γ-aminobutyric acid (GABA) concentrations decreased, while glutamate (Glu), 3-methoxytyramine (3-MT), and glycine concentrations increased, accompanied by an increase in myopic refraction and axial length (AL). Treating with D2R antagonist sulpiride increased glycine and DA levels, while decreasing 3-MT and Glu levels, accompanied by a decrease in myopic refraction and AL. The ratio of Glu to GABA (RGG) represents the balance between excitatory and inhibitory neurotransmitters, and changes in RGG correlated with changes in AL.

Summary: Room-temperature aqueous solutions of GABA and AABA were studied using DRS and statistical mechanics calculations. The results showed that only about half of the water molecules in direct contact with the solute are affected in their dynamics. GABA moderately retards -10 H2O molecules, while AABA moderately retards -6 H2O molecules and freezes -6 H2O molecules.

Summary: The study found that melatonin enhances plant tolerance to osmotic stress by increasing the ability to scavenge ROS, with the melatonin receptor CAND2 playing a key role in this process. Additionally, the expression of melatonin biosynthetic genes and the accumulation of melatonin are influenced by osmotic stress, affecting the plant's response.

Summary: Neurotransmission signaling is a conserved system with important regulatory events. The role of excitatory and inhibitory neurotransmitter systems in brain function is well established. Recent research has shown that epigenetic regulation plays a crucial role in controlling the expression of neurotransmitter-related genes and its dysregulation is associated with neurological disorders. This article explores the epigenetic regulation of dopamine, GABA, glutamate, and serotonin genes, and discusses how targeting these mechanisms can lead to improved treatments for neurological disorders.

Summary: γ-Aminobutyric acid (GABA) acts as the primary inhibitory neurotransmitter in the CNS, regulated by GABA transporters (GATs). Although GAT1 has been extensively studied, the roles of other GABA transporters, especially BGT-1, remain unclear. This review aims to compare GAT1 and BGT-1, leveraging the knowledge of GAT1 to shed light on the unanswered questions regarding BGT-1.

Summary: The study reveals that the disturbed metabolism of vitamins B1 or B6 may cause seizures, especially with stronger PTZ sensitivity in female rats. Female rats show delayed seizure with administration of vitamins B1 and B6, indicating potential therapeutic effects. Sex differences in behavior and brain biochemistry after a seizure suggest that epilepsy has sex-specific impacts on physiological and biochemical processes in the brain.

Summary: This study maps the positions and connectivity of Onecut3(+) neuronal populations in the developing and adult mouse brain. The study found that Onecut3 marks a previously undescribed neuronal cohort in the lateral hypothalamus, which expresses thyrotropin-releasing hormone. The Onecut3(+) neurons in the lateral hypothalamus have both intra- and extrahypothalamic efferents, with projections to the septal complex, habenula, neocortex, and hippocampus.

Summary: This study investigated the impact of obesity and weight loss on the expression of specific proteoglycans in adipose tissue. Transcriptomic data from human bariatric surgery cohorts and gene analyses in mice revealed altered gene expression in both visceral and subcutaneous adipose tissue depots. The gene expression changes in visceral adipose tissue were more pronounced after surgery, suggesting ongoing adipose tissue repair.

Summary: The authors used low-input methyl RNA immunoprecipitation and sequencing to map the N-6-methyladenosine (m(6)A) landscape during mouse oocyte and early embryo development. They found that retrotransposon-derived RNAs and genes involved in the maternal-to-zygotic transition are often marked by m(6)A. By applying this low-input method, they were able to define the m(6)A landscape during the maternal-to-zygotic transition, including the stage-specific expression of transcription factors that are essential for cell fate determination.

Summary: This review summarizes the key factors contributing to the onset and progress of nonalcoholic fatty liver disease (NAFLD) and discusses the role of genetic regulation of hepatic lipids in NAFLD. Studies have shown that a combination of factors, including obesity, insulin resistance, lipotoxic lipids, and genetic susceptibility, determines the severity of NAFLD. The identification of key determinants in various biological systems has shed light on the development of NAFLD.

Summary: The locus coeruleus (LC), a small nucleus in the pons, plays a crucial role in the functioning of the central nervous system, particularly in wakefulness. This study used single-cell RNA sequencing to identify different subtypes of neurons in the LC and characterized their neuropeptide and receptor profiles. The results showed that NE neurons expressed various neuropeptide transcripts, with galanin being a notable one. Surprisingly, Galr1, a galanin receptor, was highly expressed in GABA neurons surrounding the NE ensemble. Functional experiments revealed that GalR1 agonist can inhibit a significant proportion of NE neurons. These findings provide insights into the role of the galanin system in NE function and have implications for understanding the actions of other peptides and their receptors.

Summary: This study found that in patients with delirium, the concentration of the neurotoxic metabolite quinolinic acid in the cerebrospinal fluid (CSF-QA) was increased and was associated with neuronal damage markers and 1-year mortality. This discovery reveals a strong link between systemic inflammation, neurotoxicity, and delirium.
