Swiss Researchers Identify Gene Linked to Sleep Depth Variations
Researchers from Switzerland have identified a specific gene that may explain why some individuals experience deep sleep while others remain very alert.
The lead author of the study, Hans-Peter Landolt, an assistant professor at the University of Zurich, stated, “Research on animals shows that the intensity of sleep is genetically controlled; however, the physiological mechanisms remain a mystery.”
Landolt focused on the adenosine neurotransmitter system in the brain and isolated the gene that regulates adenosine. Adenosine is a component believed to affect specific receptors that induce sleep. Antagonistic components, such as caffeine, inhibit these receptors and increase alertness, keeping individuals awake.
According to Landolt, high levels of adenosine lead to drowsiness. The study indicates that adenosine plays a direct role in sleep quality. Landolt suggests that the adenosine system could be a significant target for developing medications aimed at improving sleep disorders.
