Sleep deprivation attenuates inflammatory responses and ischemic cell death.

ABSTRACT: Although the biological function of sleep remains uncertain, the consequences of sleep deprivation are well-described and are reported to be detrimental to cognitive function and affective well-being. Sleep deprivation also is strongly associated with elevated risk factors for cardiovascular disease. We used a mouse model of cardiac arrest/cardiopulmonary resuscitation to test the hypothesis that acute sleep deprivation would exacerbate neuroinflammation and neurodegeneration after global ischemia. The resulting data led to a rejection of our hypothesis that sleep deprivation is necessarily detrimental. Indeed, acute sleep deprivation (ASD) was associated with a reduction in ischemia-induced interleukin 1beta (IL-1beta) gene expression and attenuation of neuronal damage in the hippocampus.
