Sleep Deprivation Leads to Depletion of Critical Brain Protective Protein

by Kaia

A lack of sleep doesn’t just leave you feeling fatigued; it can also inflict harm on the brain, elevating the risk of debilitating conditions such as Alzheimer’s disease. Scientists exploring the underlying mechanisms of this phenomenon have achieved a significant breakthrough by pinpointing a crucial protein, pleiotrophin (PTN), which experiences a sharp decline in sleep-deprived mice. This decline triggers the death of neurons in the hippocampus, a region of paramount importance for memory retention.

Researchers have identified a notable decrease in the protein pleiotrophin (PTN) in sleep-deprived mice, which subsequently results in the death of hippocampal cells.

Genetic studies conducted in humans have indicated PTN’s involvement in Alzheimer’s and other neurodegenerative diseases.

The study, published in the ACS’ Journal of Proteome Research, highlights not only the detrimental effects of sleep deprivation but also the urgent need to comprehend the mechanisms underlying this damage. By uncovering the decline of a protective protein associated with sleep loss, researchers have taken a significant step towards comprehending the neurological consequences of inadequate sleep and its potential long-term implications, including the heightened risk of Alzheimer’s and other neurological disorders.
