Circadian rhythm, a natural cycle that regulates many biological processes, operates on a 24-hour cycle. Changes in light and dark significantly impact circadian cycles, and abnormalities can disrupt ...
In experimental settings, CB1 agonists like THC do alter sleep architecture, shifting NREM and REM balance and restructuring intermediate sleep stages.
Researchers discovered that more than 300 liver genes are under circadian control: Circadian variations affect how much of a drug is available and how effectively the body can break it down. Giving ...
Scientists have identified a protein in the visual system of mice that appears to be key for stabilizing the body's circadian rhythms by buffering the brain's response to light. The finding advances ...
The rising and setting of the sun influences the function of every cell in our bodies. Almost every organism on earth—from single-cell algae to humans—has an internal circadian clock which is a ...
Scientists at the Johns Hopkins University School of Medicine and the National Institutes of Health have identified a protein in the visual system of mice that appears to be key for stabilizing the ...
The fruit fly circadian cycle shares three strong similarities with the mammalian: the per gene itself, CLOCK and BMAL regulation of per, and a gene called tau in hamsters and double-time (dbt) in ...

Alzheimer's disrupts circadian rhythms of plaque-clearing brain cells, mouse study shows
Alzheimer's disease is notorious for scrambling patients' daily rhythms. Restless nights with little sleep and increased napping during the day are early indicators of disease onset, while sundowning, ...
To activate T cells, DCs take up, process, and present antigens as part of major histocompatibility complexes (MHCs) that interact with T cell receptors. Therefore, Curtis and her team set out to ...
