Impact of REM sleep deprivation and sleep recovery on circulatory neuroinflammatory markers.

Abstract

OBJECTIVES: Sleep loss may contribute to neuroinflammation, which might increase neuroinflammatory markers such as neuron-specific enolase (NSE), creatine kinase-brain fraction (CK-BB), lactate dehydrogenase brain fraction (LDH-BB) in blood. Hence, we evaluated the effect of REM sleep deprivation and recovery on these markers. MATERIAL AND METHODS: Twenty-four adult male Sprague Dawley rats were grouped as control, environmental control, REM sleep deprivation, and 24 hour sleep recovery. The rats were sleep deprived for 72 hours and recovered for 24 hours. NSE, CK-BB, and LDH-BB levels in serum were measured using ELISA. RESULTS: >0.05). DISCUSSION: REM sleep deprivation increased serum NSE, CK-BB, and LDH-BB, which might be due to neural damage. However, 24 hours of sleep recovery restored these markers.
