Summary: In the striatum, cholinergic interneurons can release both acetylcholine and glutamate, and their individual and combined contributions to behavior regulation were assessed in mice using reward-based touchscreen tests. Changes in VAChT and VGLUT3 levels have different effects on reward responses, and the simultaneous loss of both vesicular transporters affects dopamine signaling and behavior in a more severe way than the loss of VAChT alone. This shows that the ability of CINs to secrete two different neurotransmitters allows for complex modulation of various behaviors.

Summary: Drug addiction is manifested in some individuals and involves multifaceted processes such as cognitive control failures. Impulsivity, which includes reckless behavior without foresight, underlies most drug-taking behavior. While the neural substrates of the relationship between trait impulsivity and drug compulsion are poorly understood, advances have been made in studying limbic cortico-striatal circuits and neuromodulatory influences.

Summary: Neurotransmitters are chemical messengers that play a crucial role in information processing in the nervous system, and are essential for healthy physiological and behavioral functions in the body. Dysregulation of neurotransmitter systems is typically associated with specific neurological disorders. Recent research has shown that each neurotransmitter system has a distinct pathogenic role in multiple neurological disorders of the central nervous system. This review provides updated information on each neurotransmitter system, including their synthesis and regulation, functions, pathogenic roles in diseases, diagnostics, therapeutic targets, and currently used drugs for associated neurological disorders. It also discusses recent developments in neurotransmitter-based therapeutics and future perspectives in this area of research.

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: Neurotransmitter transporters play a crucial role in regulating neurotransmitter concentration and can be dynamically regulated through redistribution and stabilization. This allows for adjustments in uptake capacity for different neurotransmitters in response to changes in neuronal activity, blood flow, and cell-to-cell interactions.

Summary: Proper brain development relies on timely availability of thyroid hormone (TH), which requires regulated expression of TH signaling components. Abnormal TH levels and mutations in TH signaling components can have detrimental effects on brain development and neurological functions. The involvement of TH signaling in the development of different neurotransmitter systems has gained attention. This review summarizes the regulation of TH signaling components during brain development and discusses how altered TH signaling compromises the development of specific neuron types.

Summary: This study presents a topographical distribution map of dopamine, GABA, and glutamate neurons in the ventral tegmental area of mice. The majority of neurons expressed a single type of mRNA, while a subset of neurons co-expressed two or three molecular characteristics. These different neuronal populations were distributed differently across sub-nuclei in the ventral tegmental area, suggesting a complex organization of neuronal molecular characteristics and potentially diverse functions.

Summary: Striatal dopamine release is inhibited by striatal gamma-aminobutyric acid (GABA) acting via GABA(A) and GABA(B) receptors, which is regulated by plasma membrane GABA uptake transporters on striatal astrocytes. The regulation of striatal GABA-DA interactions serves as a potential therapeutic target for psychomotor disorders associated with dysregulated DA signaling.

Summary: The aim of this study was to investigate the effects of alcohol intoxication and withdrawal on neurohormones and neurotransmitters in the brain. Specifically, the researchers focused on the involvement of corticotropin-releasing factor (CRF) and arginine vasopressin (AVP), as well as the two CRF receptors (CRF1 and CRF2). The results showed that the changes in neuroendocrine levels were mediated by CRF1, except for the changes in AVP concentration which were not mediated by CRF receptors.

Summary: This study investigates the mechanisms of eCB mobilization in the DLS, and finds that brief bouts of synaptic stimulation induce long lasting eCB transients, mainly generated by 2-AG mobilization. The efficient mobilization of 2-AG requires coactivation of multiple receptors and is inhibited by dopamine D2 receptors.

Summary: Animal and human postmortem studies have shown that there are changes in gamma-aminobutyric acid (GABA) and glutamate in the prefrontal cortex (PFC) during adolescence, indicating shifts in excitation and inhibition balance consistent with critical period plasticity. However, how GABA and glutamate change in humans during adolescence and how the balance of these neurotransmitters changes is not well understood.

Summary: Adolescence is a critical period of neurocognitive development, with prolonged maturation of the prefrontal cortex and improvements in executive function. Stress experienced during adolescence can affect critical period plasticity mechanisms and cognitive outcomes, with acute stress enhancing cognition and excitatory processes in specific contexts, while chronic stress dampening excitatory and inhibitory processes and impairing cognition.

Summary: This study investigates the role of GABA and glutamate in cognitive inhibition during cognitive flexibility. The results suggest that cognitive inhibition and behavioral inhibition are functionally distinct faculties, and they rely on different brain structures and neurotransmitter systems.

Summary: The A391T missense mutation in ZIP8 results in reduced zinc transport, altered glutamate signaling, and an exacerbated immune and inflammatory response. Re-expression of wild-type ZIP8 or application of the zinc chelator ZX1 can rescue the observed phenotypes. These findings provide novel therapeutic targets relevant to schizophrenia.

Summary: TAK-653 is a novel AMPAR-positive allosteric modulator being developed for major depressive disorder. Noninvasive neurostimulation experiments showed that TAK-653 increased specific electrophysiological responses in both rats and healthy humans, suggesting that TMS may be a useful translational platform for assessing the pharmacodynamic profile of glutamate receptor modulators.

Summary: Dopamine is involved in stress-related illnesses, and corticotropin-releasing factor plays a role in stress responses. This study examined the synaptic terminals between dopamine and non-dopamine cells and found that dopamine regulation may occur indirectly through contacts with non-dopamine neurons.
