Overwhelming evidence indicates the involvement of immune-inflammatory processes in the pathophysiology of major depressive disorder (MDD). Peripheral cytokine alterations serve as one of most consistently reported indices of subthreshold inflammatory state observed in MDD. Although cytokines cannot pass directly through the blood-brain barrier, a number of transport mechanisms have been reported. In addition, peripheral cytokines may impact central nervous system via downstream effectors of their biological activity...

Psoriasis has an enormous impact on patients' lives and is frequently associated with depression. Depression in psoriasis may be attributed, at least in part, to elevated proinflammatory cytokines rather than the psychosocial impact of psoriasis itself. Biologics that target inflammatory cytokines treat the clinical manifestations of psoriasis, but may also play a role in reducing associated depression. Multiple biologics have decreased symptoms of depression during clinical trials in psoriasis; however, these studies used a variety of depression screening tools, which limits comparison...

Connexin 43 (Cx43) plays an important role in the pathogenesis of atrial fibrillation (AF). The present study sought to investigate the effect of macrophage migration inhibitory factor (MIF), a pleiotropic cytokine, on Cx43 expression and activity and determine the intracellular signaling pathways. Cx43 protein and mRNA levels were assayed using immunofluorescence, real-time PCR, and western blot. We found that increased MIF and extracellular regulated protein kinases (ERK) expression was accompanied by a significant reduction in Cx43 protein expression in atrial tissues from patients with AF compared with those with sinus rhythm...

Many breast cancer survivors have to deal with a variety of psychological and physiological sequelae including impaired immune responses. The primary purpose of this randomized controlled trial was to determine the efficacy of a mindfulness-based stress reduction (MBSR) intervention for mood disorders in women with breast cancer. Secondary outcomes were symptom experience, health status, coping capacity, mindfulness, posttraumatic growth, and immune status. This RTC assigned 166 women with breast cancer to one of three groups: MBSR (8 weekly group sessions of MBSR), active controls (self-instructing MBSR) and non-MBSR...

Major depressive disorder (MDD) is not a single disease, but a number of various ailments that form one entity. Psychomotor retardation, anhedonia, sleep disorders, an increased suicide risk, and anxiety are the main symptoms that often define the clinical diagnosis of depression. Interleukin-6 (IL-6), as one of the proinflammatory cytokines, seems to be overexpressed during certain mental disorders, including MDD. Overexpression of IL-6 in depression is thought to be a factor associated with bad prognosis and worse disease course...

To investigate the mechanism of cyclooxygenase 2 (COX2) in learning and memory impairments in rats subjected to chronic unpredictable mild stress (CUMS), meloxicam was used intragastrically to inhibit the activity of cyclooxygenase 2. Moreover, cyclooxygenase 2 over-expressing or RNA interfere lentivirus was injected intraventricularly to increase or decrease the enzyme's expression, respectively. The body weights and sucrose consumption were used to analyze depressive behaviors, while the Morris water maze and step-down-type passive avoidance tests were carried out to evaluate the learning-memory functions...

A history of repeated concussion has been linked to the later development of neurodegeneration, which is associated with the accumulation of hyperphosphorylated tau and the development of behavioral deficits. However, the role that exogenous factors, such as immune activation, may play in the development of neurodegeneration following repeated mild traumatic brain injury (rmTBI) has not yet been explored. To investigate, male Sprague-Dawley rats were administered three mTBIs 5 days apart using the diffuse impact-acceleration model to generate ∼100G...

BACKGROUND: Corrective surgery for congenital heart defects is known to trigger a severe immune reaction. There has been extensive research on the effects of inflammation after cardiopulmonary bypass (CPB). Interestingly, monocytes are observed to be non-responsive to stimulation with lipopolysaccharide (LPS) under these conditions, indicating a state of immunodepression, which lays the ground for second hit infections after cardiosurgery with CPB. OBJECTIVES: The aim of this prospective study was to analyze immunodepression after pediatric cardiopulmonary bypass and to differentiate the effects of monocytic anergy on postoperative outcome...

Notch signaling enhanced the response of interleukin (IL)-22-producing CD4(+) T cells that were defined as T helper 22 (Th22) cells, and Notch-aryl hydrocarbon receptor (AhR)-IL-22 axis fine-tuned inflammatory response. Previous studies have demonstrated that both Notch signaling and Th22 cells took part in the pathogenesis of chronic hepatitis C virus (HCV) infection. Thus, in this study, we aimed at examining the regulatory role of Notch signaling in Th22 cells in HCV infection. A total of 59 patients with chronic hepatitis C and 22 normal controls (NCs) were enrolled in this study...

BACKGROUND: Recognition of cardiomyopathy in sepsis can be challenging due to the limitations of conventional measures such as ejection fraction (EF) and fractional shortening (FS) in the context of variable preload and afterload conditions. This study correlates myocardial function using strain echocardiography (SE) with cardiomyocyte oxidative stress in a murine model of sepsis. METHODS: C57BL/6J mice were randomized into control (n = 10), sham (n = 25), and a cecal ligation and puncture (CLP) (n = 33) model of sepsis...

Neuropathic pain, a maladaptive and chronic condition that can develop after a lesion or disease affecting the somatosensory system, is characterized by allodynia, hyperalgesia and spontaneous pain, and comorbidities such as sleep deprivation, depression and anxiety. The activation of microglial cells in response to nerve injury has been implicated in the development of neuropathic pain. Mediators such as Neuregulin-1, matrix metalloproteinase (MMP)-2, MMP-9, The chemokine (C-C motif) ligand 2 (CCL2) and fractalkine are released after nerve injury and are involved in the activation of microglial cells...

Preclinical studies have largely supported that alcohol-consumption induces the development of an important neuro-inflammation and this neuro-inflammation contributes to alcohol-drinking behaviors, notably through TLR4 and LPS related mechanisms. The neuro-inflammation originates from a direct interaction of ethanol with the neuronal and immune brain cells, but also from the generation of an inflammation at the periphery. Ethanol in particular interacts with the intestine to develop a gut dysbiosis and an increase in gut permeability, that allows the liberation of bacterial fragments to the systemic circulation and induces a pro-inflammatory response in the systemic circulation and peripheral organs, and in particular the liver...

BACKGROUND: Exendin-4 is a peptide agonist of the glucagon-like peptide-1 (GLP-1) receptor, currently in clinical trials as a potential disease-modifying therapy for Parkinson's disease. In light of this, it is important to understand potential modes of action of exendin-4 in the brain. Exendin-4 is neuroprotective and has been proposed to be directly anti-inflammatory, and that this is one way it reduces neurodegeneration. However, prior studies have focused on animal models involving both neurodegeneration and inflammation, therefore, it is also possible that the observed decreased inflammation is secondary to reduced neurodegeneration...

Serum inflammatory markers have been studied in adults with anxiety and depression, but little is known about cytokine levels in young adolescents with emotional disorders. The objective of this study is to compare serum levels of interleukin-6 (IL-6) and interleukin-10 (IL-10) between adolescents with internalizing disorders and adolescents from the same community without internalizing disorders. A total of 134 non-medicated subjects (n=76 with internalizing disorders) were recruited from a larger sample of 2457 individuals...

The characteristics of the cycles of activity and rest stand out among the most intensively investigated aspects of circadian rhythmicity in humans and experimental animals. Alterations in the circadian patterns of activity and rest are strongly linked to cognitive and emotional dysfunctions in severe mental illnesses such as Alzheimer's disease (AD) and major depression (MDD). The proinflammatory cytokine interleukin 6 (IL-6) has been prominently associated with the pathogenesis of AD and MDD. However, the potential involvement of IL-6 in the modulation of the diurnal rhythms of activity and rest has not been investigated...

Mycobacterium tuberculosis (Mtb) early secreted protein antigen 6 (ESAT-6) and culture filtrate protein 10 (CFP-10) are among candidate vaccines against tuberculosis (TB). Results of experimental animal models show that these antigens are associated with induction of strong T cell immunity (IFN-γ production), while others report that these proteins as virulent factors involved in pathogenicity of Mtb infection. However, the role of ESAT-6/CFP-10 during natural Mtb infections in humans has not been established...

BACKGROUND: Structured exercise training has been proposed as a useful adjunctive therapy for Crohn's disease by improving immune function and psychological health, reducing fatigue and promoting gains in muscle and bone strength. However, the evidence for exercise in Crohn's disease is sparse, with only a handful of small prospective trials [1, 2], with methodological limitations, including the use of non-randomised and non-controlled study designs and small sample sizes. Here, we describe the protocol for a study that aims to assess the feasibility and acceptability of two common types of exercise training-high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT)-in adults with inactive or mildly active Crohn's disease (CD)...
