%0 Journal Article %T To Sleep, Perchance to Survive? %J - %D 2019 %R https://doi.org/10.1016/j.it.2019.02.006 %X Multicellular organisms exist in a sea of microbes. Survival is enabled by an immense diversity of antimicrobial peptides (AMPs) that maintain homeostasis with the microbiota. During pathogen infection, fruit fly survival varies directly with sleep. A newly-identified fruit fly sleep-regulator is also an AMP (Toda et al. Science 2019;363:509¨C515). Its characterization may clarify the association between sleep and surviving infection %U https://www.cell.com/trends/immunology/fulltext/S1471-4906(19)30041-9
