We aimed to evaluate the effect of paradoxical sleep deprivation on the cellular migration during inflammation, the peritoneal macrophage phenotype and the infectious stimulus outcomes. A/J mice were inoculated with thioglycollate and exposed to paradoxical sleep deprivation. Sleep-deprived animals presented decreased cell migration compared to controls. Nitric oxide production was reduced in macrophages from sleep-deprived mice compared to controls. Cell surface analysis showed that sleep deprivation reduced F4/80(+)/CD80(low) peritoneal cell population induced by thioglycollate injection. Sleep-deprived mice were not more susceptible to infection than control mice. Our findings challenge the general perception that sleep loss always increases infection susceptibility.
