Microglia are the resident immune cells of the central nervous system (CNS) and they contribute to primary inflammatory responses following CNS injuries. The morphology of microglia is closely associated with their functional activities. Most previous research efforts have attempted to delineate the role of ramified and amoeboid microglia in the pathogenesis of neurodegenerative diseases. In addition to ramified and amoeboid microglia, bipolar/rod-shaped microglia were first described by Franz Nissl in 1899 and their presence in the brain was closely associated with the pathology of infectious diseases and sleeping disorders...

Dermatologic symptoms can be associated with posttraumatic stress disorder (PTSD) in several situations: (1) as features of some core PTSD symptoms, such as intrusion symptoms manifesting as cutaneous sensory flashbacks, as autonomic arousal manifesting as night sweats and idiopathic urticaria, and as dissociation manifesting as numbness and dermatitis artefacta; (2) the cutaneous psychosomatic effects of emotional and physical neglect and sexual abuse (eg, infantile eczema, cutaneous self-injury, and body-focused repetitive behaviors such as trichotillomania and skin picking disorder) and eating disorders, which can have dermatologic effects; (3) the direct effect of physical or sexual abuse or catastrophic life events (eg, earthquakes) on the skin; and (4) as a result of significant alterations in hypothalamic-pituitary-adrenal and sympatho-adrenal medullary axes, which can affect neuroendocrine and immune functions, and can lead to exacerbations of stress-reactive inflammatory dermatoses such as psoriasis, chronic urticaria, and atopic dermatitis...

PURPOSE: The purpose of this study is to determine the role of T lymphocyte immune imbalance and interleukin (IL)-10 gene polymorphism in the development of obstructive sleep apnea (OSA) in obese children. METHODS: One hundred obese children at high-risk and low-risk for OSA based upon a sleep questionnaire were selected. Peripheral blood T lymphocyte subsets were measured by flow cytometry, and plasma IFN-γ, IL-4, and IL-10 cytokines were detected by ELISA. The relationships between OSA and the above variables were analyzed...

Shift workers suffer from a constellation of symptoms associated with disruption of circadian rhythms including sleep abnormalities, and abnormal hormone secretion (e.g. melatonin, cortisol). Recent, but limited, evidence suggests that shift workers have elevated levels of circulating white blood cells (WBCs) compared to their day working counterparts. Interestingly, recent reviews highlight the strong linkage between the immune system and circadian rhythms which includes, but is not limited to, circulating cell populations and functions...

OBJECTIVES: Mindfulness based interventions (MBI) have recently gained much interest in western medicine. MBSR paradigm is based on teaching participants to pay complete attention to the present experience and act nonjudgmentally towards stressful events. During this mental practice the meditator focuses his or her attention on the sensations of the body. While the distractions (mental images, thoughts, emotional or somatic states) arise the participant is taught to acknowledge discursive thoughts and cultivate the state of awareness without immediate reaction...

Sleep is an active process; the body undergoes restoration and regeneration. Adequate sleep is essential to health and cognitive function. Sleep is critical for cell repair, a healthy immune system, and hormonal regulation, and aids in the process of learning, memory, and emotion. Inadequate sleep can lead to multiple chronic health and mental conditions over time. The occupational health nurse can be instrumental in screening for two of the most common sleep disorders, insomnia and obstructive sleep apnea, by asking workers key questions and using simple screening tools...

The sleep disorder narcolepsy with cataplexy is characterized by a highly specific loss of hypocretin (orexin) neurons, leading to the hypothesis that the condition is caused by an immune or autoimmune mechanism. All genetic variants associated with narcolepsy are immune-related. Among these are single nucleotide polymorphisms in the P2RY11-EIF3G locus. It is unknown how these genetic variants affect narcolepsy pathogenesis and whether the effect is directly related to P2Y11 signalling or EIF3G function. Exome sequencing in 18 families with at least two affected narcolepsy with cataplexy subjects revealed non-synonymous mutations in the second exon of P2RY11 in two families, and P2RY11 re-sequencing in 250 non-familial cases and 135 healthy control subjects revealed further six different non-synonymous mutations in the second exon of P2RY11 in seven patients...

BACKGROUND: Type-D personality, defined as a combination of high negative affect and high social isolation, has been associated with poor health outcomes. However, pathways underlying this association are largely unknown. We investigated the relationship between Type-D personality and several biological and behavioral pathways including the autonomic nervous system, the immune system, glucose regulation and sleep in a large, apparently healthy sample. METHODS: Data from a total of 646 respondents (age 41...

A risk factor relationship exists between periodontal disease and Alzheimer's disease (AD) via tooth loss, and improved memory following dental intervention. This links the microbial contribution from indigenous oral periodontal pathogens to the manifestation of chronic conditions, such as AD. Here, we use Porphyromonas gingivalis infection to illustrate its effect on mental health. P. gingivalis infection, in its primary sub-gingival niche, can cause polymicrobial synergy and dysbiosis. Dysbiosis describes the residency of select commensals from the oral cavity following co-aggregation around the dominant keystone pathogen, such as P...

Narcolepsy is an orphan neurological disease and presents with sleep-wake, motoric, neuropsychiatric and metabolic symptoms. Narcolepsy with cataplexy is most commonly caused by an immune-mediated process including genetic and environmental factors, resulting in the selective loss of hypocretin-producing neurons. Narcolepsy has a major impact on workableness and quality of life. Areas covered: This review provides an overview of the temporal available treatment options for narcolepsy (type 1 and 2) in adults, including authorization status by regulatory agencies...

BACKGROUND: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is characterized by unexplained persistent fatigue, commonly accompanied by cognitive dysfunction, sleeping disturbances, orthostatic intolerance, fever, lymphadenopathy, and irritable bowel syndrome (IBS). The extent to which the gastrointestinal microbiome and peripheral inflammation are associated with ME/CFS remains unclear. We pursued rigorous clinical characterization, fecal bacterial metagenomics, and plasma immune molecule analyses in 50 ME/CFS patients and 50 healthy controls frequency-matched for age, sex, race/ethnicity, geographic site, and season of sampling...

Adenotonsillar regrowth in children after adenotonsillectomy (T&A) for obstructive sleep apnea (OSA) is often seen in clinical treatment, however, the relationship between allergic disease and adenotonsillar regrowth remains unclear. In this retrospective study, children were assigned to either the recurrence or control group, and subdivided by age at operation. Among children over 36 months, those in the recurrence group had more allergic disease and higher IgE, IL-4, and IL-5 levels than the same-aged children in control group...

Crosstalk between the lung and the kidney is based on the similarities that these organs share. This is why different diseases that affect one organ can have repercussions on the other. Patients with acute kidney injury can present complications such as pulmonary edema and require mechanical ventilation in respiratory failure. This interaction occurs due to the increase in systemic immune mediators that cause inflammatory reactions, oxidative stress, and an increase in vascular permeability in the lung. With regard to lung-induced renal damage, the kidney can also be affected by chemical mediators, which are translocated into the bloodstream...

REVIEW

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...

Prostaglandin D2 (PGD2) is a lipid mediator involved in sleep regulation and inflammation. PGD2 interacts with 2 types of G protein-coupled receptors, DP1 and DP2/CRTH2 (chemoattractant receptor homologous molecule expressed on T helper type 2 cells)/GPR44 to show a variety of biological effects. DP1 activation leads to Gs-mediated elevation of the intracellular cAMP level, whereas activation of DP2 decreases this level via the Gi pathway; and it also induces G protein-independent, arrestin-mediated cellular responses...

Insomnia is a serious worldwide health threat, affecting nearly one third of the general population. Melatonin has been reported to improve sleep efficiency and it was found that eating melatonin-rich foods could assist sleep. During the last decades, melatonin has been widely identified and qualified in various foods from fungi to animals and plants. Eggs and fish are higher melatonin-containing food groups in animal foods, whereas in plant foods, nuts are with the highest content of melatonin. Some kinds of mushrooms, cereals and germinated legumes or seeds are also good dietary sources of melatonin...

Sleep is considered to be an important predictor of the immunity, since the absence of sleep can affect the development of the immune response, and consequently increase the susceptibility to contract an infection. The aim of the present study was to investigate if sleep deprivation and stress induce dysregulation of the duodenal mucous membrane during the acute infection with Trichinella spiralis. Our results shows that, in the intestinal mucous membrane, stress and sleep deprivation, produces different effect in the cells, and this effect depends on the studied duodenal compartment, glands or villi...
