BACKGROUND: Cardiovascular disease (CVD) and depression are extremely prevalent and debilitating conditions. Evidence suggests there is a two-way relationship between depression and CVD. Inflammation is implicated in the pathophysiology of both conditions, thus representing a central candidate mediating the link between these disorders. Depression is consistently associated with increased inflammation and increased blood levels of inflammatory molecules. In recent years, studies have shown that depression significantly increases the risk of developing inflammatory-related diseases such as CVD, precipitated by the same inflammatory pathways involved in the pathophysiology of CVD...

Accumulating evidence indicates an interaction between inflammation and depression since increased levels of pro-inflammatory cytokines are associated with depression-related symptoms. Melatonin is a hormone synthesized and secreted by the pineal gland with antioxidant, anti-inflammatory and antidepressant-like effects. In this way, it would be interesting to evaluate the putative antidepressant-like effect of melatonin treatment in an acute inflammation mice model of depression. The present study aimed to investigate the effect of melatonin treatment on lipopolysaccharide (LPS) induced depressive-like behavior, neuroinflammation, oxidative stress and alteration on brain-derived neurotrophic fator (BDNF) levels...

Opioid-induced neuroinflammation and the nitric oxide (NO) signal-transduction pathway are involved in the development of opioid analgesic tolerance. The antidepressant venlafaxine (VLF) modulates NO in nervous tissues, and so we investigated its effect on induced tolerance to morphine, neuroinflammation, and oxidative stress in mice. Tolerance to the analgesic effects of morphine were induced by injecting mice with morphine (50 mg/kg) once a day for three consecutive days; the effect of co-administration of VLF (5 or 40 mg/kg) with morphine was similarly tested in a separate group...

Recovery from major depressive disorder is difficult, particularly in patients who are refractory to antidepressant treatments. To examine factors that regulate recovery, we developed a prolonged learned helplessness depression model in mice. After the induction of learned helplessness, mice were separated into groups that recovered or did not recover within 4 weeks. Comparisons were made between groups in hippocampal proteins, inflammatory cytokines, and blood brain barrier (BBB) permeability. Compared with mice that recovered and control mice, non-recovered mice displaying prolonged learned helplessness had greater hippocampal activation of glycogen synthase kinase-3 (GSK3), higher levels of tumor necrosis factor-α (TNFα), interleukin-17A, and interleukin-23, increased permeability of the blood brain barrier (BBB), and lower levels of the BBB tight junction proteins occludin, ZO1, and claudin-5...

Recently, it was suggested that resveratrol (RES), a natural polyphenol, possesses beneficial therapeutic roles in depression. The aim of this review is to discuss the novel potential pharmacological effects of RES on depression. We first consider the pathophysiology of depression and then review the potential antidepressant effects of RES. Apart from the alternation of the monoaminergic system and the molecular markers related to depression, RES might exert an antidepressant-like effect through modulating the HPA axis, BDNF and synaptic vesicle proteins, inflammatory cytokines and oxidative stress, and thyroid hormones...

In the last several years a large number of studies have demonstrated the neurobiological and clinical continuum between depression and Alzheimer's disease (AD). Depression is a risk factor for the development of AD, and the presence of depressive symptoms significantly increases the conversion of Mild Cognitive Impairment (MCI) into AD. Common pathophysiological events have been identified in depression and AD, including neuroinflammation with an aberrant Tumor Necrosis Factor-α (TNF-α) signaling, and an impairment of Brain-Derived Neurotrophic Factor (BDNF) and Transforming-Growth-Factor-β1 (TGF-β1) signaling...

Background: The altered expression and function of dopamine receptor D3 (D3R) in patients and animal models have been correlated with depression disease severity. However, the morphological alterations and biological effects of D3R in the brain after inflammation-induced depressive-like behavior remain elusive. Methods: In the present study, we ascertained the changes of D3R expression in the brain regions after depressive-like behavior induced by peripheral administration of lipopolysaccharide (LPS)...

Several lines of evidence link macrophage activation and inflammation with (monoaminergic) nervous systems in the etiology of depression. IFN treatment is associated with depressive symptoms, whereas anti-TNFα therapies elicit positive mood. This study describes the actions of 2 monoaminergic antidepressants (escitalopram, nortriptyline) and 3 anti-inflammatory drugs (indomethacin, prednisolone, and anti-TNFα antibody) on the response of human monocyte-derived macrophages (MDMs) from 6 individuals to LPS or IFN-α...

Antidepressant-like effects of ethanolic extract of Hericium erinaceus (HE) mycelium enriched in erinacine A on depressive mice challenged by repeated restraint stress (RS) were examined. HE at 100, 200 or 400 mg/kg body weight/day was orally given to mice for four weeks. After two weeks of HE administration, all mice except the control group went through with 14 days of RS protocol. Stressed mice exhibited various behavioral alterations, such as extending immobility time in the tail suspension test (TST) and forced swimming test (FST), and increasing the number of entries in open arm (POAE) and the time spent in the open arm (PTOA)...

Major depressive disorder (MDD) is a chronic condition that affects one in six adults in the US during their lifetime. The current practice of antidepressant medication prescription is a trial-and-error process. Additionally, over a third of patients with MDD fail to respond to two or more antidepressant treatments. There are no valid clinical markers to personalize currently available antidepressant medications, all of which have similar mechanisms targeting monoamine neurotransmission. The goal of this review is to summarize the recent findings of immune dysfunction in patients with MDD, the utility of inflammatory markers to personalize treatment selection, and the potential of targeting inflammation to develop novel antidepressant treatments...

BACKGROUND: The etiopathogenesis of psychiatric disorders is still not completely understood. Growing evidence supports the hypothesis that mental illness and related disturbances in the brain neurobiology do not necessarily originate in the brain. Inflammation has been suggested to play a central role in psychiatric disorders, and altered levels of peripheral cytokines have been reported in several studies. OBJECTIVE AND METHODS: In this review, we present and discuss studies exploring the role of dysbiosis and products of the gut-microbiota in the pathogenesis of psychiatric disorders, as well as its potential involvement in mediating the effect of antidepressants, mood stabilizers, and antipsychotics...

PURPOSE: Rosenblat and McIntyre (Acta Psychiatr Scand. 2015;132: 180-191) propose that immune disorders are important mediators between bipolar disorders and medical comorbidities. Rosenblat et al (Bipolar Disord. 2016;18:89-101) present a meta-analysis showing that adjunctive anti-inflammatory agents could evoke moderate antidepressant responses in bipolar disorders. We propose using the anti-inflammatory drug colchicine to improve the long-term safety and efficacy of lithium treatment for bipolar disorders...

Patients with major depressive disorder have elevated peripheral inflammation; the degree of this increase correlates with the severity of the disorder. Chronic psychological stress increases pro-inflammatory cytokines and promotes microglial activation, leading to stress vulnerability. Epigenetics, including DNA methylation and histone modification, are also related to the pathophysiology of major depressive disorder. Sodium butyrate (SB), a histone deacetylase inhibitor, exerts an antidepressant effect by altering gene expression in the hippocampus...

Silymarin, a plant-derived polyphenolic flavonoid of Silybum marianum, elicited significant antidepressant-like activity in an acute restraint stress model of depression. It improved monoamines, mainly 5-hydroxytryptamine (5-HT) levels in the cortex, dopamine (DA) and norepinephrine (NE) in the cerebellum in mice. The present study was undertaken to explore the antidepressant potential of silymarin in chronic unpredictable mild stress (CUMS) induced depressive-like behavior in mice, and to find out its probable mechanism(s) of action, mainly neurogenesis, neuroinflammation, and/or oxidative stress...

BACKGROUND: The NLRP3 inflammasome activation and neuroinflammation are known to be involved in the pathology of depression, whereas autophagy has multiple effects on immunity, which is partly mediated by the regulation of inflammasome and clearance of proinflammatory cytokines. Given the emerging evidence that autophagy dysfunction plays an essential role in depression, it is very likely that autophagy may interact with the inflammatory process in the development and treatment of depression...

Time dependent sensitization (TDS) - phenomenon described originally by Chiodo and Antelman (1980) in context of dopamine receptors, refers to cascade of events that continue to develop in the organism, after the initiating stimulus is no longer available. Treatment could be recognized as such a initiating stimulus (in case of depression, example of electroconvulsive therapy would be obvious, but some aspects of pharmacotherapy too). The process leads to improvement, but, on the other hand, phenomena of kindling in recurrent depression is well known (more relapses and therapies make heavier and longer lasting subsequent episodes)...

Studies suggest that heightened peripheral inflammation contributes to the pathogenesis of major depressive disorder. We investigated the effect of chronic social defeat stress, a mouse model of depression, on blood-brain barrier (BBB) permeability and infiltration of peripheral immune signals. We found reduced expression of the endothelial cell tight junction protein claudin-5 (Cldn5) and abnormal blood vessel morphology in nucleus accumbens (NAc) of stress-susceptible but not resilient mice. CLDN5 expression was also decreased in NAc of depressed patients...

Inflammation seems to play a role in the pathophysiology of mood disorders, including major depressive disorder (MDD) and bipolar disorder (BD). In the last years several studies have shown increased levels of inflammatory and/or immune markers in patients with mood disorders. Accordingly, the immune system has become a target of interest for the development of biomarkers and therapeutics for mood disorders. Areas covered: Here, we review the evidence showing low-grade inflammation in mood disorders and the studies evaluating immune-based strategies for the treatment of these conditions...

Clinical and experimental studies have shown that mild traumatic brain injury (mTBI) is associated with increased anxiety- and depression-related behaviors and inflammation in the brain. Unfortunately, there are no specific therapies for long-term behavioral consequences of mTBI. This study set out to determine whether silymarin treatment compared to diazepam (DZP) and fluoxetine (FLX) can reduce neuroinflammation, anxiety- and depression-like behaviors after mTBI induction in mice. We used open field, elevated plus maze, light-dark box, zero maze, sucrose preference, forced swim, and tail suspension tests to assess anxiety and depression-like behaviors in mTBI-induced mice...

Depression is characterized by mental retardation, interest blank, hypoactivity, anxiety, appetite loss, sexual dysfunction, sleep disorders and other symptoms. The incidence of depressed patients has demonstrated an upward trend in recent years. Antidepressant drugs are commonly used in modern medicine, but they have the side effect of drug resistance. This study aims to explore the effect of acupuncture stimulation on expressions of macrophage-related cytokines in mice with depression induced by chronic unpredictable mild stress (CUMS), and to explore the underlying immunological mechanism...
