Article Abstract
Circadian rhythms play a crucial role in regulating various physiological processes, including specific immune functions that enhance the body's ability to anticipate and respond to threats effectively. However, research on the impact of circadian rhythms on osteoimmunology remains limited. Our study uncovered that circadian disruption leads to bone mass loss by reducing the population of Treg cells in the bone marrow. Furthermore, we observed a significant decrease in serum IL-10 cytokine levels in jet lagged mice. In our current investigation, we explored the anti-osteoclastogenic effects of IL-10 and found that IL-10 inhibits RANKL-induced osteoclastogenesis in a dose-dependent manner. Our findings suggest that the diminished anti-osteoclastogenic properties of Tregs under circadian disruption are mediated by IL-10 cytokine production. Moreover, our discoveries propose that administration of IL-10 or butyrate could potentially reverse bone mass loss in individuals experiencing jet lag.

The uncharted effects of cadmium and cesium on circadian syndrome (CircS), an emerging circadian rhythm disorder drawing considerable attention, and underlying mechanisms warrant exigent elaboration. Data of 11141 subjects from National Health and Nutrition Examination Survey 2005-2018 were incorporated to investigate separate-, joint-/interaction-, and mixture-effects of urinary cadmium and cesium on prevalent CircS risk exploiting survey weight regression and quantile g-computation. The underlying mechanisms were probed by network toxicological analysis.

In many model organisms, the circadian system has been proposed to comprise multiple oscillators that interact to promote accuracy of the clock as well as intricacies of rhythmic outputs. In Neurospora crassa, the circadian transcriptional/translational loop comprising of the FRQ (Frequency) and WCC (White Collar Complex) proteins has been instrumental in explaining many attributes of the clock including entrainment and rhythms in development and gene expression; in addition, some non-circadian oscillations can be unmasked when the FRQ-WCC feedback loop is eliminated. These rhythms have often lost defining circadian characteristics and are potentially controlled by other oscillators, termed FRQ-less oscillators (FLOs) in Neurospora.

Sleep disorders encompass a range of diseases and symptoms that disrupt individual sleep patterns, degrade sleep quality, and diminish sleep efficiency. Currently, the mechanisms governing sleep regulation and the etiology of sleep disorders remain unclear, leading to clinical treatments that are primarily symptomatic due to the absence of precise intervention methods. Recent studies suggest that glymphatic-meningeal lymphatic route is responsible for the clearance of macromolecular metabolites from the brain, thus playing a pivotal role in maintaining sleep homeostasis and circadian rhythm.

The offshore renewable energy industry is expanding rapidly due to decarbonisation commitments and need for energy security. This will change the marine environment in ways that are not fully understood, including more subsea power cables in the sea. Movement of electricity through these cables generates an electromagnetic field (EMF), which might affect marine species.

Current research indicates that insulin secretion deficiency in β-cells contributes to Type 2 diabetes mellitus (T2DM), which is associated with neuropeptide Y receptor (Npy1r) overexpression from neuropeptide Y (NPY) system dysregulation. To date, limited literature has explored nobiletin (NOB) as a circadian modulator for restoring β-cell function through Npy1r regulation. This study investigates NOB's stimulatory effects on insulin secretion via Npy1r and clock-modulatory signaling to elucidate its underlying mechanism.
