However, the underlying cause of these sleep disturbances is not well understood. Here, we assessed the sleep architecture of male mice infected with<jats:italic>T. brucei<\/jats:italic>and found that infected mice had drastically altered sleep patterns. Interestingly,<jats:italic>T. brucei<\/jats:italic>-infected mice also had a reduced homeostatic sleep response to sleep deprivation, a response modulated by the adenosine system. We found that infected mice had a reduced electrophysiological response to an adenosine receptor antagonist and increased adenosine receptor gene expression. Although the mechanism by which<jats:italic>T. brucei<\/jats:italic>infection causes these changes remains to be determined, our findings suggest that the symptoms of sleeping sickness may be because of alterations in homeostatic adenosine signaling.<\/jats:p><jats:p><jats:bold>SIGNIFICANCE STATEMENT<\/jats:bold>Sleeping sickness is a fatal disease that disrupts the circadian clock, causes disordered temperature regulation, and induces sleep disturbance. To examine the neurologic effects of infection in the absence of other symptoms, in this study, we used a mouse model of sleeping sickness in which the acute infection was treated but brain infection remained. Using this model, we evaluated the effects of the sleeping sickness parasite,<jats:italic>Trypanosoma brucei<\/jats:italic>, on sleep patterns in mice, under both normal and sleep-deprived conditions. Our findings suggest that signaling of adenosine, a neuromodulator involved in mediating homeostatic sleep drive, may be reduced in infected mice.<\/jats:p>","DOI":"10.1523\/jneurosci.1046-20.2020","type":"journal-article","created":{"date-parts":[[2020,10,23]],"date-time":"2020-10-23T21:45:19Z","timestamp":1603489519000},"page":"9306-9316","source":"Crossref","is-referenced-by-count":18,"title":["Sleeping
