Different synaptic mechanisms of intermittent and continuous theta-burst stimulations in a severe foot-shock induced and treatment-resistant depression in a rat model. Exp Neurol 2023; 362:114338. [PMID: 36717014 DOI: 10.1016/j.expneurol.2023.114338] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2022] [Revised: 01/04/2023] [Accepted: 01/24/2023] [Indexed: 01/28/2023]
Abstract
Treatment-resistant depression (TRD) is a condition wherein patients with depression fail to respond to antidepressant trials. A new form of repetitive transcranial magnetic stimulation (rTMS), called theta-burst stimulation (TBS), which includes intermittent theta-burst stimulation (iTBS) and continuous theta-burst stimulation (cTBS), is non-inferior to rTMS in TRD treatment. However, the mechanism of iTBS and cTBS underlying the treatment of TRD in the prefrontal cortex (PFC) remains unclear. Hence, we applied foot-shock stress as a traumatic event to develop a TRD rat model and investigated the different mechanisms of iTBS and cTBS. The iTBS and cTBS treatment were effective in depressive-like behavior and active coping behavior. The iTBS treatments improved impaired long-term potentiation and long-term depression (LTD), whereas the cTBS treatment only improved aberrant LTD. Moreover, the decrease in mature brain-derived neurotrophic factor (BDNF)-related protein levels were reversed by iTBS treatment. The decrease in proBDNF-related protein expression was improved by iTBS and cTBS treatment. Both iTBS and cTBS improved the decreased α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors and downregulation of mammalian target of the rapamycin (mTOR) signaling pathway. The iTBS produces both excitatory and inhibitory synaptic effects, and the cTBS only produces inhibitory synaptic effects in the PFC.

Abstract
Corticosterone (CORT) treatment has been evidenced to develop a depression-like state in animals, that mimic hypothalamic-pituitary-adrenal (HPA)-axis dysregulation implicated in the development of depression. The present study aimed to examine the ferulic acid (FA), a natural phenolic compound, antidepressant and antioxidant activities on the CORT chronic model. Mice orally treated with 20mg/kg of CORT for 21days were connsidered control group, while mice treated with FA (1mg/kg) or fluoxetine (10mg/kg) for the last week of CORT treatment, as drug groups. Three weeks of CORT treatment resulted in depressive-like behavior, as indicated by the increase on the immobility time in the tail suspension test, grooming in the splash test and an increase in the oxidative stress markers in the brain. It was observed that FA ameliorated the behavioral and oxidative stress alterations induced by CORT, which may plausibly suggest a mode of action for the FA antidepressant effect. The involvement of FA repairing the stress caused by HPA-axis dysfunction evidenced that this phenolic acid could be further investigated as a novel potential agent to improve the management of depression.

Abstract
Adolescents living with human immunodeficiency virus (HIV) comprise approximately 12% of the HIV-positive population worldwide. HIV-positive adolescents experience a higher rate of clinical depression, a greater risk of sexual and drug abuse behaviors, and a decreased adherence to highly active antiretroviral therapies (HAART). Using adolescent HIV-1 transgenic rats (HIV-1 tg) that display related immune response alterations and pathologies, this study tested the hypothesis that developmental expression of HIV-1-related proteins induces a depressive-like phenotype that parallels a decrease in hippocampal cell proliferation and an increase in pro-inflammatory cytokine expression in the hippocampus. Consistent with this hypothesis, adolescent HIV-1 tg rats demonstrated a depressive-like behavioral phenotype, had decreased levels of cell proliferation, and exhibited elevated expression of monocyte chemotactic protein-1 (Mcp-1) in the hippocampus relative to controls. Subsequently, we tested the ability of meloxicam, a selective COX-2 inhibitor, to attenuate behavioral deficits via inflammatory mechanisms. Daily meloxicam treatments did not alter the behavioral profile despite effectively reducing hippocampal inflammatory gene expression. Together, these data support a biological basis for the co-morbid manifestation of depression in HIV-positive patients as early as in adolescence and suggest that modifications in behavior manifest independent of inflammatory activity in the hippocampus.

Abstract
Depression is one of the most frequent neuropsychiatric comorbidities associated with opiate addiction. Mitogen activated protein kinase (MAPK) and MAPK phosphatase (MKP) are involved in drug addiction and depression. However, the potential role of MAPK and MKP in depression caused by morphine withdrawal remains unclear. We utilized a mouse model of repeated morphine administration to examine the molecular mechanisms that contribute to prolonged withdrawal induced depressive-like behaviors. Depressive-like behaviors were significant at 1 week after withdrawal and worsened over time. Phospho-ERK (extracellular signal-regulated protein kinase) was decreased and MKP-1 was elevated in the hippocampus, and JNK (c-Jun N-terminal protein kinase), p38 (p38 protein kinase) and MKP-3 were unaffected. A pharmacological blockade of MKP-1 by intra-hippocampal sanguinarine (SA) infusion prevented the development of depressive-like behaviors and resulted in relatively normal levels of MKP-1 and phospho-ERK after withdrawal. Our findings support the association between hippocampal MAPK phosphorylation and prolonged morphine withdrawal-induced depression, and emphasize the MKP-1 as an negative regulator of the ERK phosphorylation that contributes to depression.

Repeated clomipramine treatment reversed the inhibition of cell proliferation in adult hippocampus induced by chronic unpredictable stress. THE PHARMACOGENOMICS JOURNAL 2008; 8:375-83.

Abstract
Adult hippocampal neurogenesis has been demonstrated in several species and is regulated by both environmental and pharmacological stimuli. Repeated exposure to stress is known to induce the reduction of neurogenesis in the dentate gyrus (DG) of hippocampus. The present study aimed at determining whether the clinically effective antidepressant clomipramine may influence hippocampal proliferation and neurogenesis in adult rats subjected to the chronic unpredictable stress (CUS) procedure, a model of depression with predictive validity. Repeated administration of clomipramine (5 mg kg(-1), intraperitoneal) for 3 weeks, starting 2 weeks after the beginning of the stress procedure, significantly reversed the reduction of behavior measured by open-field test and forced swimming test. Moreover, rats subjected to stress exhibited a 49.9% reduction of cell proliferation at the end of a 5-week stress period, an effect which was suppressed by clomipramine treatment. These results demonstrated that exposure to CUS, which results in a state of behavioral depression, decreases hippocampal cell proliferation and that these effects can be counteracted by chronic clomipramine treatment.

Abstract
BACKGROUND Brain-derived neurotrophic factor (BDNF) has been hypothesized to be involved in the neurobiology of major depression. The aim of this study was to assess the possible relationships between depressive symptoms and serum and/or plasma BDNF levels during 1 year of antidepressant treatment. METHODS Plasma and serum BDNF levels were assayed in 15 drug-free depressed patients and in 15 healthy control subjects at baseline and the 1st, 3rd, 6th and 12th month of antidepressant treatment. RESULTS At baseline, patients' serum and plasma BDNF levels were significantly lower (p<.001 and p=.004, respectively) than those found in healthy control subjects. However, while from the 1st month of treatment patients' plasma BDNF levels did not differ significantly from those observed in healthy control subjects, serum BDNF levels in patients remained significantly lower at all times. LIMITATIONS The main limitations of the current study are represented by the small sample size and the high discontinuation rate. CONCLUSIONS Untreated depressed patients showed reduced baseline serum and plasma BDNF levels, as compared with control subjects. The clinical improvement paralleled the normalization of plasma BDNF after 1 month of treatment, while, at every assessment time, patients' serum BDNF levels were lower than those of control subjects. This would suggest that serum BDNF might represent a non-specific trait marker of depression.

Abstract
The hypothalamic-pituitary-adrenocortical (HPA) system in drug abusers may be affected due to disorders of the hypothalamic dopaminergic system. The present study investigated alterations in the adenohypophysis of middle-aged drug abusers (40-60 years of age), using clusterin-containing mixed cell-follicles as the indicator, in which clusterin (apolipoprotein J) is a multifunctional glycoprotein related to neurodegeneration. The paraffin-embedded adenohypophyses of methamphetamine and psychotropic drug abusers (n = 76) were compared with those of non-abusers (n = 82). The number of follicles was larger in drug abusers independent of the immediate cause of death, although the size was not significantly different. When cell types forming the follicles were immunohistochemically examined, drug abusers showed an increase of prolactin (PRL) cells and gonadotroph cells and a reciprocal decrease of growth hormone cells, suggesting hypofunction of dopaminergic neurons in the hypothalamus, while there was no change in the adrenocorticotropic hormone and thyroid-stimulating hormone cells. These increases of the clusterin-containing follicles and PRL cells in the follicles may be related to the dysfunction of dopaminergic neurons in the hypothalamus of chronic drug abusers and may be useful for investigating drug abuse in forensic casework.
