The relationship between aberrant neuronal activation in the pregenual anterior cingulate, altered glutamatergic metabolism, and anhedonia in major depression. Also, a few studies have reported that factors such as chronic stress that reduce brain levels of glutamate and glutamine causing hypoactive glutamatergic signaling in the mouse prefrontal cortex are also associated with the development of depression[44], suggesting that regarding brain glutamatergic transmission a delicate balance always needs to be maintained. Anxiety, Depression, and the Microbiome: A Role for Gut Peptides. Effect of co-administration of fluoxetine and amantadine on immunoendocrine parameters in rats subjected to a forced swimming test. Download scientific diagram | Ceftriaxone reduced the concentration of glutamate in cerebrospinal fluid (CSF) of PSD rats. eCollection 2022. The results of a preclinical study by Kos and Popik[111] revealed a dose-dependent antidepressant-like response in the tail-suspension test, with the response observed at a dose of 15 mg/kg persisting with sub-chronic administration. Depression. Melancholic microbes: a link between gut microbiota and depression? Glutamate is one of the most prominent neurotransmitters in the brain and regulates large regions of the nervous system. There is enough evidence from studies to support the notion that regulation of glutamatergic neurotransmission through mGlu receptors is associated with the development of mood, leading to suggestions that they could serve as novel targets in depression management[128,129]. Glutamine is an amino acid synthesized by your body from another amino acid known as glutamic acid or glutamate. PMC Are the HLA Genes Related to Non-Celiac Wheat Sensitivity? Koike H, Chaki S. Requirement of AMPA receptor stimulation for the sustained antidepressant activity of ketamine and LY341495 during the forced swim test in rats. Current perspectives on the development of non-biogenic amine-based antidepressants. Clinical depression or major depressive disorder (MDD) is a chronic, debilitating, and disabling mental health disorder that affects over 300 million people (across all age groups) globally[1-4]. J Physiol. Abdallah CG, Adams TG, Kelmendi B, Esterlis I, Sanacora G, Krystal JH. MSG also increased serotonin uptake in the cerebral cortices and caused deregulation of the hypothalamic-pituitary-adrenal axis, Anxiolytic and memory-enhancing effects at low doses of MSG; however, at higher doses, anxiety and memory retardation were observed, Higher doses of dietary glutamate resulted in an increase in plasma glutamate and glutamine but no difference in total brain glutamate or glutamine levels, Anxiolytic response in females, and anxiogenic response in males following dietary MSG. Two of these visits will use MRI methods to evaluate the structure and function of the brain. This suggests that depression is not an irreversible neurodegenerative disorder. Ketamine: In humans, ketamines ability to alleviate depressive symptoms (Table (Table4)4) was first highlighted by a small, randomized, double-blind study demonstrating that a single subanaesthetic (0.5 mg/kg) dose of ketamine administered intravenously improved depressive symptoms within 72 h in seven persons with treatment resistant MDD[68]. Glutamate as a therapeutic target in psychiatric disorders. This study showed that l-glutamine supplementation showed antidepressant properties on adult study participants suffering from depression 3. Epub 2016 Feb 12. The https:// ensures that you are connecting to the Crosstalk between the microbiota-gut-brain axis and depression. In: European Medicines Agency [Internet]. In: World Health Organization [Internet]. This emerging concept of a microbiota-gut-brain axis suggests that our ability to modulate the gut microbiota may be a potential tool towards the development of novel therapies for complex brain disorders such as psychiatric disorders[19,71,72] (Table (Table33). The NR2B-selective NMDA antagonist (CP-101,606) that was well-tolerated and devoid of psychotropic side effects was also used in a clinical trial involving subjects with traumatic brain injury[119].

Other specific relationships involving glutamate are still being investigated, and their direct implications for therapy are being considered. such as depression and anxiety. excess glutamate is believed to be involved in a variety of neurological and neurodegenerative disorders including autism, obsessive compulsive disorders, hyperactivity disorders, complex motor stereotypes, tics, insomnia, anxiety disorders, seizures, sensory processing disorder, addiction, depression, chronic fatigue, pans, pandas, alzheimers, The neurobehavioral implications of the brain and microbiota interaction. Transferring the blues: Depression-associated gut microbiota induces neurobehavioural changes in the rat. What Is the Difference Between L-Lysine & L-Tyrosine? The antidepressant effects of amantadine have been observed in situations where it is administered in combination with standard antidepressants such as fluoxetine and imipramine[115,116]. There have been suggestions that communications occur through the activation of neurotransmitters such as serotonin, dopamine, GABA and noradrenaline in the enteric nervous system; these neurotransmitters are secreted by gut microbiota and are akin to the neurotransmitters in the central nervous system[76]. Apart from this, clinical investigations also continue to affirm that a single intravenous bolus administration of ketamine can evoke a rapid (within 2 h) and lasting (up to 7 d) antidepressant action[101-103]. Plasma Amino Acid Concentrations in Patients with Alcohol and/or Cocaine Use Disorders and Their Association with Psychiatric Comorbidity and Sex. This study involves four neuroimaging scan visits. There are a few studies that show GABA levels do increase, but none that prove beneficial results. High-fat diet induces depression-like phenotype via astrocyte-mediated hyperactivation of ventral hippocampal glutamatergic afferents to the nucleus accumbens.

Also, they do not seem to affect the extracellular concentration of monoamines[122]; yet they enhance the neurotrophic actions of BDNF mRNA and protein in primary neuronal cultures[122,123]. Cephalalgia 2019;39:428-34. headache and pericranial muscle sensitivity. Bookshelf Glutamate receptors and their transduction molecules have been demonstrated on the epithelial cells of the gut, splanchnic, vagal, and/or pelvic afferents[89-91]. More recently, there is overwhelming evidence of the anxiolytic and antidepressant response to subanaesthetic-doses of ketamine in clinical[27-30] and preclinical studies[31,32]. Also, the results of early studies showing alterations in the levels of glutamate (peripherally and centrally) in persons with mood disorders confirmed this involvement[13,26]. For more than six decades, drugs that modulate biogenic amines, increasing their availability at the synaptic cleft by selectively blocking the uptake of serotonin and/or norepinephrine have been used in the management of depression. Chaki S, Ago Y, Palucha-Paniewiera A, Matrisciano F, Pilc A. mGlu2/3 and mGlu5 receptors: potential targets for novel antidepressants. Muhonen LH, Lnnqvist J, Juva K, Alho H.

A comparison of the predictive therapeutic and undesired side-effects of the NMDA receptor antagonist, memantine, in mice. However, studies from our laboratory revealed that while orally administered monosodium glutamate was associated with the development of anxiety behaviour, especially in male mice[21,45,49], an antidepressant effect was observed in the behavioural-despair paradigms irrespective of sex[47]. However, the lack of a specific depression-associated gut microbiota profile is a major challenge[9]. That being said, diets rich in vegetables, fruits, cereals, nuts, seeds, pulses and moderate amounts of dairy, eggs, fish and unsaturated fats have been associated with a lower incidence of depression[136-139], a view not supported by some studies[140,141]. In the central and enteric nervous systems, respectively, glutamate is the major excitatory neurotransmitter[50,89]. Glutamine deficiency is not common, as it is available in food sources and your body can easily manufacture it. It also helps regulate mood. An official website of the United States government. 1) Incorporate probiotic strains that turn glutamate into GABA. Recent data indicate that a single intravenous dose of an NMDA receptor antagonist is sufficient to produce sustained relief from depressive symptoms, and represent exciting and novel avenues to both understand depressive symptomatology and develop more effective antidepressants. Despite this, the presence of bacteria that produce neuroactive molecules strengthens the link between gut microbiota and behavioural disorders such as depression. Research has continued to show that the consumption of diets rich in fat, deficient in magnesium, or high in monosodium glutamate can cause depression-like behaviours such as decreased social interaction, anhedonia and behavioural despair in rodents[35-37]. In the last few decades, there has been increasing insights into the roles played by the glutamatergic system (Figure (Figure1)1) in the pathophysiology and treatment of mood disorders generally, and depressive disorders specifically[12,22,23]. Hasler G, van der Veen JW, Tumonis T, Meyers N, Shen J, Drevets WC. Glutamate is an excitatory neurotransmitter, which means it has stimulating actions and makes neurons more likely to fire. mGlu receptors have been shown to regulate glutamates neuronal transmission through the ability to alter neurotransmitter release or modulate the post-synaptic responses to glutamate release. Moreover, antidepressant-like activity can be produced not only by drugs modulating the glutamatergic synapse, but also by agents that affect subcellular signaling systems linked to EAA receptors (e.g., nitric oxide synthase). Some of the common symptoms of depression include: * feelings of low self-worth. Psychiatric Times, Psychiatric Times Vol 36, Issue 5, Volume 36, Issue 5. Decades later, these findings eventually culminated in the approval of esketamine (Spravato) by the US Food and Drug Administration[99] and the European Medicines Agency[100]; esketamine was selectively approved for use (in addition to a known antidepressant) in adults with treatment-resistant MDD. While in health, the enteric ganglia and the brain are impermeable to dietary or luminal glutamate; there have been reports suggesting that glutamate permeability in these systems increases in diseased states such as enteric neuropathies, or conditions that alter the integrity of the blood-brain-barrier. Here we report that endogenously released glutamate and GABA can exert a powerful depressant effect on mossy fiber synapses. The monoamine hypothesis supports the notion that the pathology in depression is primarily depletion in the levels of brain monoamine neurotransmitters including serotonin, norepinephrine, and dopamine[10-12]. These limitations are evidence of therapeutics that were still based on an incomplete understanding of disease pathogenesis. Recent studies found that a low dose of the drug ketamine, which alters glutamate system activity, can rapidly eliminate depression in two-thirds of patients who do not respond to conventional antidepressants. However, despite the tantalizing prospect, the directionality and mechanism of the relationship involving diet, the gut microbiome, and depression are still subjects of research. 2022 Jun 22;14(13):3059. doi: 10.3390/cancers14133059. What mental disorder is associated with glutamate? Conflict-of-interest statement: Authors have nothing to declare. While endogenous brain glutamate has been linked to the pathophysiology of psychiatric conditions such as schizophrenia and mood disorders, the possible role of dietary glutamate (Table (Table1)1) in the development of neuropsychiatric conditions is still being evaluated[42]. However, while glutamate-based therapies for depression are still in their infancy (and much more is dietary manipulation of glutamate balance via the gut microbes), it appears that understanding the diet, gut microbiome, gut-brain axis and glutamate link may be the next frontier in advancing our understanding of depression. Dhir A. Investigational drugs for treating major depressive disorder. Is treatment-resistant depression a useful concept? Lauterborn JC, Truong GS, Baudry M, Bi X, Lynch G, Gall CM. Clinical depression occurs in several forms, including major depressive disorder, seasonal affective disorder, dysthymia and postpartum depression. Peer-review reports scientific quality classification, P-Reviewer: Pasquini M, Pavn L, Qu SQ S-Editor: Gao CC L-Editor: Webster JR P-Editor: Li JH. Auer DP, Ptz B, Kraft E, Lipinski B, Schill J, Holsboer F. Reduced glutamate in the anterior cingulate cortex in depression: an. A larger, double-blind, placebo-controlled, crossover study also found that a single ketamine infusion (0.5 mg/kg over 40 min) had a rapid, robust and mildly sustained antidepressant effect (1 wk) in treatment-resistant MDD[104]. Accessibility Although glutamate is ubiquitous in the brain, excessive release of glutamate has been associated with excitotoxicity-induced brain injury[24]. Levine et al[54], using a proton magnetic resonance spectroscopy (MRS) technique examined the relationship between cerebrospinal fluid (CSF) metabolites, such as glutamate and glutamine on depressive symptoms in hospitalized persons with severe unmedicated depression, and reported that compared to control subjects, glutamine level in the CSF of depressed patients was elevated. Adell A. Glutamatergic and neural dysfunction in postpartum depression using magnetic resonance spectroscopy. FOIA Glutamate receptors, both. Depression can leave you feeling like you've been hit by a bulldozer. Research into glutamate's role in mood disorders is underway. That depression may be linked to alterations in glutamate circuits is suggested by the observation that ketamine (which is an NMDA glutamate receptor antagonist) may rapidly reverse depression in some patients. The gut microbiome also influences brain glutamate, with the results of metabolomic studies revealing that alterations in the composition of the gut saprophytic microflora also affected brain concentrations of glutamate[93,94]. IBRO Neurosci Rep. 2022 Jun 4;13:22-30. doi: 10.1016/j.ibneur.2022.05.007. Studies have tried to research the effects of augmenting ketamine with other drugs that are probably better-tolerated; these drugs such as riluzole and lamotrigine have been examined for their ability to either improve ketamine antidepressant effects and/or reduce its psychotomimetic effects[106-108]. . 2022 Jun 20;13:926688. doi: 10.3389/fpsyt.2022.926688. Glutamine is found naturally in goods including beef, poultry, milk, cottage cheese and cabbage. The stimulation of gut glutamate receptors by dietary or luminal glutamate has been associated with the activation of vagal afferents which directly or indirectly influence brain areas such as the cerebral cortex, limbic system, hypothalamus and basal ganglia[90,92]. Kitanaka N, Kitanaka J, Hall FS, Kubota Y, Mimura Y, Ogura S, Okada Y, Uhl GR, Takemura M. Psychotomimetic-like behavioral effects of memantine in the mouse. Mathews DC, Henter ID, Zarate CA. However, the result of a large double-blind randomized Finnish study reported a significant antidepressant effect with memantine in persons with co-morbid alcohol dependence[114].
