There is a growing body of literature that recognizes the positive effects of exercise on mood states such as anxiety, stress and depression, through physiological and biochemical mechanisms, including endorphins, mitochondria, mammalian target of rapamycin, neurotransmitters and the hypothalamic-pituitary-adrenal axis, and via the thermogenic hypothesis. In addition, psychological mechanisms influence the effects of exercise on mood states, as suggested by both the distraction hypothesis and the self-efficacy hypothesis...

Extensive research links depression and inflammation, with emerging evidence suggesting some differences between males and females in these associations. However, relatively few studies have examined stimulated inflammatory responses (ex vivo) in depression. The present research investigated the associations between depressive symptoms, basal inflammation, and LPS-stimulated production of pro- (IL-1β, IL-6, IL-8, TNF-α) and an anti-inflammatory cytokine (IL-10), with a focus on the extent to which gender moderates these relationships...

OBJECTIVE: Pain and inflammation during acute myocardial infarction (AMI) have been associated with the development of posttraumatic stress disorder and may also impact negatively on somatic outcome. We investigated the relationship between pain during AMI and levels of circulating proinflammatory (tumor necrosis factor [TNF]-α, interleukin [IL]-6) and anti-inflammatory (IL-33 and tissue growth factor [TGF]-β1) cytokines. METHODS: Data were collected as part of the Myocardial Infarction - Stress Prevention Intervention (MI-SPRINT) study...

ETHNOPHARMACOLOGICAL RELEVANCE: Xylocarpus moluccensis (Lamk.) M. Roem of family Meliaceae has triterpenoids rich fruits. Triterpenoids have been known to possess cardioprotection and anti-atherosclerotic activities (Han and Bakovic, 2015; Wu et al., 2009). Standardised fraction of these fruits exhibited anti-dyslipidemic (Srivastava et al., 2015), anti-inflammatory (Ravangpai et al., 2011) and CNS depressant activity (Sarker et al., 2007). However, there is no report in the literature on its cardiovascular effects...

Depression, the most frequent psychiatric disorder following ischaemic stroke, negatively affects survivals' functional outcome, response to rehabilitation and quality of life. Approximately, one-third of them are affected by post-stroke depression (PSD), making it a serious social and public health problem and anti-depressant preventive and curative therapies worth investigating. However, a two-way association between depression and stroke has been also established: stroke increases the risk of PSD, but depression is an independent risk factor for stroke...

OBJECTIVES: Both peripheral and central brain-derived neurotrophic factor (BDNF) levels are decreased in depression and normalized by efficient anti-depressive therapies. While depression symptoms are frequent in rheumatoid arthritis, BDNF has been poorly investigated in this pathology. Therefore, the present study explored cerebral and peripheral BDNF in arthritis rats as well as the link between brain BDNF and the two factors recently involved in the pathogenesis of depression and present in rheumatoid arthritis namely inflammation and endothelial dysfunction...

Mounting evidence indicates that stress influences the experience of pain. Exposure to psychosocial stress disrupts bi-directional communication pathways between the central nervous system and peripheral immune system, and can exacerbate the frequency and severity of pain experienced by stressed subjects. Repeated social defeat (RSD) is a murine model of psychosocial stress that recapitulates the immune and behavioral responses to stress observed in humans, including activation of stress-reactive neurocircuitry and increased pro-inflammatory cytokine production...

BACKGROUND: The physiological and behavioral symptoms of sickness, including fever, anorexia, behavioral depression, and weight loss can be both beneficial and detrimental. These sickness responses are triggered by pro-inflammatory cytokines acting on cells within the brain. Previous research demonstrates that the febrile response to peripheral insults depends upon prostaglandin production by vascular endothelial cells, but the mechanisms and specific cell type(s) responsible for other sickness responses remain unknown...

Neuropathic pain manifested by a number of sensory symptoms is often accompanied by disorders of higher nervous activity, such as memory impairment, depression, anxiety, anhedonia, etc. This emphasizes the involvement of supraspinal structures including the hippocampus in neuropathic pain pathogenesis. In the present study, we focused on the impact of chronic neuropathic pain on hippocampal neurogenesis and microglial state. In addition, we test the effect of alkyl glycerol ethers on hippocampal neuronal and microglial plasticity as well as behavioral parameters...

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...

Lithium augmentation (LA) of antidepressants is a first-line therapy in treatment-resistant depression. Immunomodulatory effects of lithium have been described. The cytokine hypothesis of depression postulates that cytokines play a key role in the pathophysiology of depression. Concordantly, it has been shown that proinflammatory cytokine serum levels decrease during antidepressant treatment. The aim of this study was to investigate changes in cytokine serum levels during LA. Serum concentrations of the cytokines interleukin (IL)-2, IL-4, IL-6, IL-8, IL-10, tumour necrosis factor alpha, interferon-gamma, granulocyte and monocyte colony stimulating factor were measured in a total of 95 acutely depressed patients before and after four weeks of LA...

Recent evidence has established that consumption of High-fat diet (HFD)-induced obesity is associated with deficits in hippocampus-dependent memory/learning and mood states. Nevertheless the link between obesity and emotional disorders still remains to be elucidated. This issue is of particular interest during adolescence, which is important period for shaping learning/memory and mood regulation that can be sensitive to the detrimental effects of HFD. Our present study is focused to investigate behavioral and metabolic influences of short-term HFD intake in adolescent C57BL/6 mice...

This study was conducted to investigate the effects of dietary threonine on the disease resistance, gill immune and physical barriers function of juvenile grass carp (Ctenopharyngodon idella). A total of 1080 juveniles were fed six iso-nitrogenous diets containing graded levels of threonine (3.99-21.66 g kg(-1) diet) for 8 weeks, and then challenged with Flavobacterium columnare. Results showed that threonine deficiency (3.99 g kg(-1) diet): (1) increased the gill rot morbidity after exposure to F. columnare; (2) attenuated the gill immune barrier function by decreasing antimicrobial substances production, up-regulating the mRNA levels of pro-inflammatory cytokines (except IL-12p40), and down-regulating the anti-inflammatory cytokines partly due to the modulation of NF-κB and TOR signaling...

BACKGROUND: Maternal immune activation (MIA) is a risk factor for neurodevelopmental disorders such as autism and schizophrenia, as well as seizure development. The amygdala is a brain region involved in the regulation of emotions, and amygdalar maldevelopment due to infection-induced MIA may lead to amygdala-related disorders. MIA priming of glial cells during development has been linked to abnormalities seen in later life; however, little is known about its effects on amygdalar biochemical and cytoarchitecture integrity...

Objective To investigate the effect of guanylate-binding protein 2 (GBP2) on β-glucan-induced maturation and immune response of dendritic cells (DCs). Methods RNA-microarray and real time quantitative PCR were used to investigate the change of genes in DCs induced by β-glucan. Thereafter, DCs were transfected with GBP2 siRNA to knock down the expression of GBP2. Flow cytometry was used to detect the surface markers (CD11c, MHC-II, CD80) on DCs as well as the proliferation of T cells. Cytokines (IL-6, IL-12p70, TNF-α, IL-10) were tested by ELISA...

REVIEW
Kening Fan, Nicholas J Talley
Functional dyspepsia (FD) is a highly prevalent disorder that affects more than 10% of the population. In the past decade, the conceptual underpinning of FD has begun to change, and new data are unraveling the underlying pathophysiological mechanisms of this disorder with a focus on the duodenum. The Rome IV criteria were published in 2016, and notably suggests that gastroesophageal reflux disease and irritable bowel syndrome may all be part of the same disease spectrum as FD. Helicobacter pylori explains a minority of FD cases and in Rome IV is considered a separate entity...

Systemic inflammation induced by neonatal infection may result as long-term hyperactivation of microglial cells followed by an overproduction of pro-inflammatory cytokines, such as tumor necrosis factor (TNF-α), nitric oxide (NO), and lipid peroxidation. Those inflammation mediators can trigger behavioral disruption and/or cognitive disorders. The present work aims to evaluate the effect of melatonin (a cytokine release modulator and antioxidant agent) in the reduction of the prefrontal microglia activation and depressive-like behaviors induced by LPS injection in adult rats...

BACKGROUND: It is well established that there is a link between inflammation and depression, with several studies reporting increased circulating levels of the pro-inflammatory cytokine, interleukin-6 (IL6), in depressed individuals. Peripheral epigenetic marks, including DNA methylation, hold promise as biomarkers for a range of complex conditions, with potential to inform diagnosis and tailor interventions. The aim of this study was to determine whether individuals with depression display differential methylation of the IL6 gene promoter compared to individuals without depression...
