While the molecular and circuit mechanisms that track sleep pressure have been an area of intense focus, less attention has been placed on the downstream neurons targeted by dFB cells to change behavioral state. To identify relevant circuitry, we first used an anterograde transsynaptic labeling tool, trans-Tango, to identify postsynaptic partners of dFB. We found that neurons downstream of dFB resemble hΔF cells and through thermogenetic stimulation identify their activity to be wake promoting. We validated these results using independent genetic lines, including highly specific split-Gal4 drivers. Next, we found that hΔF neurons express the glutamate transporter VGLUT and the acetylcholine biosynthetic enzyme, Choline acetyltransferase (ChAT). Consistent with their wake promoting role, RNAi-mediated knock down of VGlut and ChAT in hΔF increases baseline sleep by sustaining sleep episodes. Furthermore, RNAi for VGlut but not ChAT in h∆F cells reduced night-time sleep loss when flies were exposed to night-time light, indicating that these cells promote arousal in response to specific sensory cues. In contrast, VGlut and ChAT knock-down in h∆F neurons resulted in enhanced sleep loss while flies were deprived of food overnight. These results suggest that hΔF cells may selectively release glutamate and acetylcholine to fine tune arousal responses to changing environmental inputs.</p>","PeriodicalId":22018,"journal":{"name":"Sleep","volume":" ","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13472897/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148164289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sleep, an important factor for both cognitive function and AD risk, may further moderate genetic influences (A), including both measured (AP) and latent (AL) components, as well as shared (C) and non-shared environmental (E) contributions to cognition. This study leveraged data from the Interplay of Genes and Environment across Multiple Studies consortium (N = 3894; 1947 complete twin pairs, 842 monozygotic (MZ) pairs and 1105 dizygotic (DZ); Average age = 62.36 years, 38.75% female). Across six cognitive abilities, we examined whether an AD polygenic score (AD-PGS) moderated environmental influences on cognitive performance. We also examined whether sleep moderated genetic and environmental contributions on cognitive performance. Although the AD-PGS accounted for a negligible proportion of genetic variance as a main effect (B's = -0.004 to 0.02), we observed environment-by-PGS interactions. Increasing genetic risk for AD was associated with lower contributions from environmental experiences unique to each individual, on episodic memory, working memory, and verbal ability (B's = -0.03 to -0.05). These interaction effects, albeit small, were primarily observed with the AD-PGS including the APOE region. Hence, the role of person-specific environments on cognitive functioning was boosted for those at lower genetic risk for AD but reduced at greater genetic risk for AD. Although sleep moderation was minimal, results suggest that poorer sleep influences genetic influences on cognitive functioning. Statement of Significance This study provides novel insights into how genetic risk for Alzheimer's disease (AD-PGS), and sleep (duration and disturbances) moderate genetic and environmental contributions to cognitive performance. Although the AD-PGS accounts for minimal genetic variance, significant but small environment-by-PGS interactions emerged. Individuals with higher AD-PGS exhibited heightened responsiveness to nonshared environmental influences on episodic memory, working memory, and verbal ability, primarily driven by the APOE ε4 region. Poorer sleep may be associated with subtle variations in genetic contributions to cognition, though moderation effects were minimal. This work offers insight into the genetic mechanisms underlying sleep, AD risk, and cognition, underscoring the need to consider both genetic susceptibility and environmental influences when examining factors that contribute to individual differences in cognition.</p>","PeriodicalId":22018,"journal":{"name":"Sleep","volume":" ","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13472895/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147780900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
