Both increased inflammation and reduced neurogenesis have been associated with the pathophysiology of major depression. We have previously described how interleukin-1 (IL-1) β,a pro-inflammatory cytokine increased in depressed patients, decreases neurogenesis in human hippocampal progenitor cells. Here, using the same human in vitro model, we show how omega-3 (ω-3) polyunsaturated fatty acids and conventional antidepressants reverse this reduction in neurogenesis, while differentially affecting the kynurenine pathway...

Brain histamine acts as a neurotransmitter and regulates various physiological functions, such as learning and memory, sleep-wake cycles, and appetite regulation. We have recently shown that histamine H3 receptor (H3R) is expressed in primary mouse microglia and has a strong influence on critical functions in microglia, including chemotaxis, phagocytosis, and cytokine secretion in vitro. However, the importance of H3R in microglial activity in vivo remains unknown. Here, we examined the effects of JNJ10181457 (JNJ), a selective and potent H3R inverse agonist, on microglial functions ex vivo and in vivo...

INTRODUCTION: A growing body of evidence shows that disturbances in the immune system are involved in the pathogenesis of depression. Although the immune-modulating effects of antidepressants have been described, few studies have addressed the functioning of the immune system in relation to electroconvulsive therapy (ECT). This study aims to investigate if the addition of ECT to pharmacotherapy is associated with changes in cytokine levels. METHODS: Adult inpatients were invited to participate in this study on admission to a psychiatric unit...

Multiple sclerosis (MS) is an inflammatory immune-mediate disorder of the central nervous system (CNS), primarily affecting the myelin sheath and followed by neurodegeneration. Synaptic alterations are emerging as critical determinants of early neurodegeneration in MS. Inflammation-induced alterations of synaptic transmission and plasticity have been investigated in vitro and also in human MS using transcranial magnetic stimulation (TMS) techniques. Specific inflammatory cytokines alter glutamatergic and GABAergic transmission, resulting in synaptic hyperexcitability...

Nonresolving low-grade inflammation is supposed to underly the basis of chronic disorders including cardiovascular diseases, cancer, diabetes, obesity, and psychiatric disorders such as depression and Alzheimer's diseases. There is increasing evidence suggesting that pathophysiology of psychiatric disorders is related to the inflammatory responses mediated by microglial cells. Elevation of intracellular Ca(2+) is important for the activation of microglial cell functions, including proliferation, release of NO, cytokines, and BDNF...

BACKGROUND: Stress is widely known to alter behavioral responses to rewards and punishments. It is believed that stress may precipitate these changes through modulation of corticostriatal circuitry involved in reinforcement learning and motivation, although the intervening mechanisms remain unclear. One candidate is inflammation, which can rapidly increase following stress and can disrupt dopamine-dependent reward pathways. METHODS: Here, in a sample of 88 healthy female participants, we first assessed the effect of an acute laboratory stress paradigm on levels of plasma interleukin-6 (IL-6), a cytokine known to be both responsive to stress and elevated in depression...

INTRODUCTION: Patients with moderate-to-severe atopic dermatitis (AD) report a multidimensional disease burden that includes impaired health-related quality-of-life (HRQoL). Changes in overall health status and specific dimensions that contribute to HRQoL were evaluated in adults with moderate-to-severe AD who participated in phase 3 clinical trials of dupilumab, which is a fully human monoclonal antibody that inhibits signaling of cytokines IL-4 and IL-13. METHODS: Two dupilumab phase 3 clinical trials of identical design included the 5-dimension 3-level EuroQol (EQ-5D) as a measure of HRQoL...

Emerging evidence indicates that the activation of indoleamine-2,3-dioxygenase (IDO), a first and rate-limiting enzyme in the kynurenine (KYN) pathway, is involved in amyloid-beta (Aβ1-42)-neurotoxicity and Alzheimer's disease (AD) pathogenesis. Physical exercise has been considered an effective intervention in AD, attenuating or limiting their progression. Nevertheless, the neurobiological mechanisms underlying the neuroprotective effects of exercise have not yet been fully elucidated. In present study, we investigated the protective effect of an 8-week swimming training (ST) exercise on cognitive and non-cognitive functions and its role in modulating biomarkers of KYN pathway, before an intracerebroventricular (i...

The wake-promoting drug Modafinil has been used for many years for treatment of Narcolepsy and Excessive Daytime Sleepiness, due to a dopamine-related psychostimulant action. Recent studies have indicated that Modafinil prevents neuroinflammation in animal models. Thus, the aim of the present study was to evaluate the effect of Modafinil pretreatment in the Lipopolysaccharide (LPS)-induced sickness and depressive-like behaviors. Adult male C57BL/6J mice were pretreated with Vehicle or Modafinil (90mg/Kg) and, 30min later, received a single saline or LPS (2mg/Kg) administration, and were submitted to the open field and elevated plus maze test 2h later...

It is well recognized that neuroinflammation is involved in the pathogenesis of various neurodegenerative diseases. Microglia and astrocytes are major pathogenic components within this process and known to respond to proinflammatory mediators released from immune cells such as mast cells. Mast cells reside in the brain and are an important source of inflammatory molecules. Mast cell interactions with glial cells and neurons result in the release of mediators such as cytokines, proteases and reactive oxygen species...

A growing number of studies show an association between seasonal allergic rhinitis (SAR) with depression and anxiety. The underlying mechanisms of a link between SAR and affect, however, are still unclear. The objective of the present study was to investigate depressive symptoms and anxiety in SAR patients and their association to inflammatory and endocrine parameters. SAR patients (n=41) and non-allergic, healthy controls (n=42) were assessed during (pollen season) and out of symptomatic periods (non-pollen season)...

BACKGROUND: Eosinophilia is a typical finding of the acute/juvenile form of paracoccidioidomycosis (PCM), a systemic mycosis endemic in Latin America. This clinical form is characterized by depressed cellular immune response and production of Th2 cytokines. Moreover, it has been shown that the increased number of eosinophils in peripheral blood of patients returns to normal values after antifungal treatment. However, the role of eosinophils in PCM has never been evaluated. This study aimed to assess the phenotypic and functional characteristics of eosinophils in PCM...

BACKGROUND: In recent years, proinflammatory cytokine interleukin-1β (IL-1β) was considered to play a critical role in the pathogenesis of depression. In addition, P2X7 receptor (P2X7R), a member of the purinergic receptor family, which is predominantly present on microglia, as well as on astrocytes and neurons in lesser amounts in the central nervous system, was suggested to be involved in the processing and releasing of IL-1β. Here, we investigated the role of P2X7R in the pathogenesis of depression...

BACKGROUND: Depression is a highly prevalent co-morbidity in Chronic Obstructive Pulmonary Disease (COPD) which was shown to be associated with a worse course of disease, including reduced quality of life and increased symptoms burden, healthcare use, and even mortality. It has been speculated that systemic inflammation may play a role in the presence of depression. Currently, physical activity is an important lifestyle factor that has the potential to modify inflammatory cytokines and depression, however our understanding of how to use exercise effectively in COPD patients to alleviate depression related systemic inflammation is incomplete and has prompted our interest to identify the type and intensities of effective exercise...

Breast cancer survivors are an expanding population that is troubled by lasting mental health problems, including depression and anxiety. These issues reduce quality-of-life throughout survivorhood. Research indicates that tumor biology, cancer treatments, and stress contribute to these mood disturbances. Although the mechanisms underlying these various causes remain under investigation, neuroinflammation is a leading hypothesis. To date, rodent models of recurrence-free tumor survival for understanding mechanisms by which these behavioral issues persist after cancer are lacking...
