Behav Brain Res 2024; 461:114834. [PMID: 38142859 DOI: 10.1016/j.bbr.2023.114834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 12/21/2023] [Accepted: 12/21/2023] [Indexed: 12/26/2023]
Abstract
Memantine, an N-Methyl-D-Aspartate (NMDA) antagonist, has been examined as a potential treatment for Obsessive-Compulsive Disorder (OCD). Yet, there is limited knowledge regarding how it works to reduce compulsive behaviour and whether it has different effects on individuals based on their sex. Herein, we investigated if there are sex differences in the anticompulsive-like effect of memantine in adult Swiss mice. Additionally, we explored whether the nitric oxide (NO) pathway and α-amino-3-hydroxy-5-methyl-4-isoazolepropionic acid (AMPA) receptors play a role in memantine's effects. To start, we assessed the impact of a single intraperitoneal dose of memantine (at 3, 5, and 10 mg/kg) on behaviours exhibited in the open field test (OFT) and the marble-burying test (MBT), the latter being a predictive test for anticompulsive effects. All doses of memantine reduced marble-burying behaviour in both male and female mice without affecting their locomotor activity in the OFT. This anticompulsive-like effect was also confirmed in another predictive test, the nest-building test, with the highest memantine dose (10 mg/kg) reducing nest-building behaviour without significant differences between male and female mice. We observed that pre-treatment with L-arginine, a NO precursor, mitigated the anticompulsive-like effect of memantine in male mice but had no effect in female mice in the MBT. Finally, NBQX, an AMPA receptor antagonist, did not block the anticompulsive-like effect of memantine. In summary, our study suggests that the anticompulsive-like effect of memantine does not appear to be sex-specific, does not depend on AMPA receptors, and involves the NO pathway primarily in male mice.

Prospective study on the association between serum amino acid profiles and depressive symptoms among the Japanese working population. PLoS One 2021; 16:e0256337.

Abstract
Objective Accumulating evidence suggests that amino acids, particularly tryptophan and glutamate, play an important role in the pathology of depression, but prospective epidemiologic data on this issue is scarce. We examined the association between circulating amino acids and the risk of depressive symptoms in a Japanese working population. Methods Participants were 841 workers who were free from depressive symptoms and provided blood at baseline and completed 3-yr follow-up survey. 30 varieties of amino acid concentrations in serum were measured using liquid chromatography/mass spectrometry. Depressive symptoms were defined using the Center for Epidemiologic Studies Depression Scale. Logistic regression was used to calculate the odds ratios of depressive symptoms according to serum amino acids with adjustment for lifestyle factors. Results A total of 151 (18.0%) workers were newly identified as having depressive symptoms at the follow-up. Baseline tryptophan and glutamate concentrations in serum were not appreciably associated with the risk of depressive symptoms. Risk of depressive symptoms tended to increase with increasing arginine concentrations; the multivariable-adjusted odds ratio for the highest versus lowest tertile of serum arginine was 1.65 (95% confidence interval: 0.96–2.83; P for trend = 0.07). No clear association was found for other amino acids. Conclusions Results of the present study do not support a significant role of circulating amino acids in the development of depressive symptoms among Japanese.

Abstract
Dysregulation of the hypothalamus-pituitary-adrenal (HPA) axis is often linked to the neurobiology of depression, though the presence and type of this dysregulation is not a consistent finding. Meanwhile, significant sex differences exist regarding depression and the HPA axis. Animal models of depression simulate certain aspects of the human disease and aim to advance our knowledge regarding its neurobiology and discover new antidepressant treatments. Most animal models of depression induce a depressive-like phenotype taking advantage of stressful experimental conditions, that also increase corticosterone, the main stress hormone in rodents. In this review we present inconsistent results in male and female rodents regarding the interaction between the depressive-like behavioral phenotype and corticosterone. In commonly used models, the female depressive-like phenotype in rodents seems significantly less dependent on the stress hormone corticosterone, whereas the male behavioral response is more evident and associates with variations of corticosterone. Further research and clarification of this sex-dependent interaction will have significant ramifications on the improvement of the validity of animal models of depression.

Abstract
Depressive disorders have complex and multi-faceted underlying mechanisms, rendering these disorders difficult to treat consistently and effectively. One under-explored therapeutic strategy for alleviating mood disorders is the targeting of microRNAs (miRs). miRs are small non-coding RNAs that cause sequestration/degradation of specific mRNAs, thereby preventing protein translation and downstream functions. miR-155 has validated and predicted neurotrophic factor and inflammatory mRNA targets, which led to our hypothesis that miR-155 deletion would modulate affective behaviors. To evaluate anxiety-like behavior, wildtype (wt) and miR-155 knockout (ko) mice (littermates; both male and female) were assessed in the open field and on an elevated plus maze. In both tests, miR-155 ko mice spent more time in open areas, suggesting they had reduced anxiety-like behavior. Depressive-like behaviors were assessed using the forced swim test. Compared to wt mice, miR-155 ko mice exhibited reduced float duration and increased latency to float. Further, although all mice exhibited a strong preference for a sucrose solution over water, this preference was enhanced in miR-155 ko mice. miR-155 ko mice had no deficiencies in learning and memory (Barnes maze) or social preference/novelty suggesting that changes in mood were specific. Finally, compared to wt hippocampi, miR-155 ko hippocampi had a reduced inflammatory signature (e.g., decreased IL-6, TNF-a) and female miR-155 ko mice increased ciliary neurotrophic factor expression. Together, these data highlight the importance of studying microRNAs in the context of anxiety and depression and identify miR-155 as a novel potential therapeutic target for improving mood disorders.

Abstract
Adult neurogenesis has been implicated in affective disorders and the action of antidepressants (ADs) although the functional significance of this association is still unclear. The use of animal models closely mimicking human comorbid affective and anxiety disorders seen in the majority of patients should provide relevant novel information. Here, we used a unique genetic mouse model displaying higher trait anxiety (HAB) and comorbid depression-like behavior. We demonstrate that HABs have a lower rate of hippocampal neurogenesis and impaired functional integration of newly born neurons as compared with their normal anxiety/depression-like behavior (NAB) controls. In HABs, chronic treatment with the AD fluoxetine alleviated their higher depression-like behavior and protected them from relapse for 3 but not 7 weeks after discontinuation of the treatment without affecting neurogenesis. Similar to what has been observed in depressed patients, fluoxetine treatment induced anxiogenic-like effects during the early treatment phase in NABs along with a reduction in neurogenesis. On the other hand, treatment with AD drugs with a particularly strong anxiolytic component, namely the neurokinin-1-receptor-antagonist L-822 429 or tianeptine, increased the reduced rate of neurogenesis in HABs up to NAB levels. In addition, challenge-induced hypoactivation of dentate gyrus (DG) neurons in HABs was normalized by all three drugs. Overall, these data suggest that AD-like effects in a psychopathological mouse model are commonly associated with modulation of DG hypoactivity but not neurogenesis, suggesting normalization of hippocampal hypoactivity as a neurobiological marker indicating successful remission. Finally, rather than to higher depression-related behavior, neurogenesis seems to be linked to pathological anxiety.

Abstract
Estradiol has antidepressive and anxiolytic actions. However, its therapeutic use is limited by its peripheral effects. Selective estrogen receptor modulators may represent an alternative to estradiol for the treatment of depressive symptoms. Here we report that tamoxifen and raloxifene decrease immobility time in the forced swim test and increases the time spent in open arms in the elevated plus maze in ovariectomized mice submitted to chronic unpredictable stress.
