Project description:Sleep is a complex and conserved biological process that affects several body functions and behaviors. Evidence suggests that there is a reciprocal interaction between sleep and immunity. For instance, fragmented sleep can increase the probability of parasitic infections and reduce the ability to fight infections. Moreover, viral and bacterial infections alter the sleep patterns of infected individuals. However, the effects of macro-parasitic infections on sleep remain largely unknown. In this study, we investigated whether macro-parasite infections could alter the sleep of their hosts. We experimentally infected three-spined sticklebacks (Gasterosteus aculeatus) with the tapeworm Schistocephalus solidus and used a hidden Markov model to characterize sleep behavior in sticklebacks. One to four days after parasite exposure, infected fish showed no difference in sleep compared with non-exposed fish, whereas fish that were exposed-but-not-infected slept less during daytime. 29-32 days after exposure, infected fish slept more than uninfected fish, while exposed-but-not-infected fish slept less than non-exposed fish. Using brain transcriptomics, we identified immune- and sleep-associated genes that potentially underlie the observed behavioral changes. These results provide insights into the complex association between macro-parasite infection, immunity, and sleep in fish and may thus contribute to a better understanding of reciprocal interactions between sleep and immunity.

Project description:Eleven healthy human subjects were enrolled in a 6-day simulated shift work protocol. Blood samples were collected during the two 24-hour measurement periods. Blood samples were collected every 4 hours during both measurement periods. Subjects entered the lab on Day 1. At the start of Day 2, the first 24-hour measurement period was started. Subjects slept according to their habitual sleep/wake schedule, followed by a 16-hour constant posture procedure. On days 3-6, the sleep period was delayed by 10 hours. Participants in the control group were exposed to dim light throughout the waking periods; participants in the bright group were exposed to bright light (~6,000lux) for 8 hours during the waking period. Following the third night on this schedule, subjects underwent another 24-hour measurement period. During both measurement periods, blood samples were collected and PBMCs were isolated. mRNA was extracted, labelled, and hybridized to microarrays.

Project description:Short sleep duration is associated with adverse metabolic, cardiovascular, and inflammatory effects. Co-twin study methodologies account for familial (e.g., genetics and shared environmental) confounding, allowing assessment of subtle environmental effects, such as the effect of short habitual sleep duration on gene expression. Therefore, we sought to investigate gene expression in monozygotic twins discordant for actigraphically phenotyped habitual sleep duration. Eleven healthy monozygotic twin pairs (82% female; mean age 42.7 years; SD=18.1), selected based on subjective sleep duration discordance, were objectively phenotyped for habitual sleep duration with two-weeks of wrist actigraphy. Peripheral blood leukocyte (PBL) RNA from fasting blood samples was obtained on the final day of actigraphic measurement and hybridized to Illumina humanHT-12 microarrays. Differential gene expression was determined between paired samples and mapped to functional categories using Gene Ontology. Next, a more comprehensive gene set enrichment analysis was performed based on the entire PBL transcriptome. The mean 24 hour sleep duration of the total sample was 439.2 minutes (SD=46.8 minutes; range 325.4 to 521.6 minutes). Mean within-pair sleep duration difference per 24 hours was 64.4 minutes (SD=21.2; range 45.9 to 114.6 minutes). The twin cohort displayed distinctive pathway enrichment based on sleep duration differences. Short sleep was associated with up-regulation of genes involved in transcription, ribosome, translation and oxidative phosphorylation. Unexpectedly, genes down-regulated in short sleep twins were highly enriched in immuno-inflammatory pathways such interleukin signaling and leukocyte activation, as well as developmental programs, coagulation cascade, and cell adhesion. Objectively assessed habitual sleep duration in monozygotic twin pairs appears to be associated with distinct patterns of differential gene expression and pathway enrichment. By accounting for familial confounding and measuring real life sleep duration, our study shows the transcriptomic effects of short sleep on dysregulated immune response and provides a potential link between sleep deprivation and adverse metabolic, cardiovascular and inflammatory outcomes.

Project description:<p>Sleep is essential for life. A good night's sleep is pleasurable and sleep deprivation is stressful. Prolonged sleep loss impairs temperature control, metabolism, immunity, and ultimately leads to death. Extensive observational and epidemiological evidence indicates that optimal sleep duration of 8 hours is associated with the maintenance of good health. In our society, however, most people only get 6.5 - 7 hours. Suboptimal sleep duration has a strong association with mortality and morbidity. Lack of sleep has been linked to cardiovascular diseases, obesity, hypertension, type 2 diabetes, and other health/cognition conditions. It is clear that the biological need for sleep varies dramatically among humans. Sleep and circadian disorders can include Familial Advanced Sleep Phase (FASP), Delayed Sleep Phase (DSP), Advanced Sleep Phase (ASP), Natural Short Sleepers (NSS) or Long Sleeping. In example, Natural Short Sleepers (NSS) have a lifelong tendency to sleep only 4 - 6 hours per night and to awaken refreshed and energetic. Natural Long Sleepers biologically require 9 - 10 hours/night to feel well rested.</p> <p>The 'Sleep and Circadian Disorders Study' (SACDS) at the University of California San Francisco, set out to investigate the mechanisms involved in regulating sleep duration, patterns and sleep quality regulation by identifying and characterization of individuals and families with unusual sleep and circadian rhythm behavior patterns.</p> <p>SACDS participants were screened with a "General Sleep Questionnaire" that inquired about multiple aspects of sleep, including habitual work-day versus non-work day sleep-wake schedules, permits calculation of subjective habitual initial sleep onset, final sleep offset, and number of awakenings.

Project description:Although the specific functions of sleep have not been completely elucidated, the literature has suggested that sleep is essential for proper homeostasis. Sleep loss is associated with changes in behavioral, neurochemical, cellular, and metabolic functions as well as impaired immune response. We evaluated the gene expression profiles of healthy volunteers submitted to 48 hours of prolonged wakefulness (PW) followed by 12 hours of sleep recovery (SR) using high-resolution microarrays. Peripheral whole blood was collected in the morning before the initiation of sleep deprivation (baseline), after the second night of PW, and one night after SR. the identified differentially expressed genes were related to immune response, DNA damage and repair as well as inflammation. Examples of these include: killer cell lectin-like receptors family granzymes and T-cell receptors, which play important roles in host defense. These results support the idea that sleep loss can lead to alteration of molecular processes that drive perturbation of cellular immunity, induction of inflammatory response and homeostatic imbalance. Moreover, down-regulation of multiple genes after prolonged wakefulness (in comparison with baseline condition) and up-regulated after sleep recovery (in comparison with prolonged wakefulness condition) were observed, suggesting an attempt of the body to re-establish internal homeostasis. In silico validation of alterations in the expression of CETN3, DNAJC, IGFR2B and CEACAM genes, confirmed the previous findings related to the molecular effects of sleep deprivation. It is clear that confirmatory studies will be necessary to fully validate the potential candidate genes and functional networks identified. Nevertheless, the present findings confirm that the effects of sleep deprivation are not restricted to the brain and can occur intensely in peripheral tissues. The peripheral blood from each volunteer (nine individuals) were collected in the baseline night and every morning after PW and after the night of SR.

Project description:Introduction: Sleep deprivation is associated with increased cardiovascular risk, which is more pronounced in women than men; however, causal evidence is lacking and the underlying mechanisms are unclear. We used randomized crossover design of prolonged sleep deprivation that mimics “life-like conditions” and endothelial cells (ECs) harvested from healthy women to investigate directly whether sleep deprivation impairs endothelial function and to identify underlying mechanisms. Methods: Healthy women with normal habitual sleep (7-9 h/day) were randomly allocated to 6-weeks of adequate sleep (7-9 h/day) or sleep deprivation (1.5 h less than habitual sleep) in a crossover design. Sleep duration was monitored objectively by actigraphy. EC harvesting and brachial artery flow-mediated dilation (FMD) were performed at baseline and the end of adequate sleep and sleep deprivation period. Results: Twenty-eight healthy women (mean [SE] age 35±13 years; BMI 25±3 kg/m2) participated. Compared with adequate sleep, sleep deprivation reduced FMD (mean±SE 8.65±0.48 vs. 7.35±0.39, p=0.02) and increased EC inflammation (nuclear factor-κB nuclear fluorescence area mean±SE 1.36±0.24 vs. 2.04±0.38 μm2, p=0.03 and mRNA expression of vascular cell adhesion molecule-1 mean±SE 1.00±0.19 vs. 2.31±0.72, p=0.04) compared with adequate sleep. Sleep deprivation increased EC oxidative stress by 67% compared with adequate sleep (redox sensitive fluorogenic probe fluorescence intensity, p=0.002) without upregulating antioxidant response. Using RNA-seq and a predicted protein-protein interaction algorithm, we identified reduced expression of serum response factor, a transcription factor that primes cortical response to sleep deprivation, and its endothelial target Defective in Cullin Neddylation-1 Domain Containing 3 as novel mediators of impaired nuclear factor (erythroid-derived 2)-like 2-mediated antioxidant responses in ECs in sleep deprivation. Conclusion: Sleep deprivation impairs clearance of endothelial oxidant stress accumulated during wakefulness leading to endothelial dysfunction and potentially increased cardiovascular risk in women.
