{"doi":"10.7554/elife.85251","title":"Tau polarizes an aging transcriptional signature to excitatory neurons and glia","abstract":"Aging is a major risk factor for Alzheimer’s disease (AD), and cell-type vulnerability underlies its characteristic clinical manifestations. We have performed longitudinal, single-cell RNA-sequencing in Drosophila with pan-neuronal expression of human tau, which forms AD neurofibrillary tangle pathology. Whereas tau- and aging-induced gene expression strongly overlap (93%), they differ in the affected cell types. In contrast to the broad impact of aging, tau-triggered changes are strongly polarized to excitatory neurons and glia. Further, tau can either activate or suppress innate immune gene expression signatures in a cell-type-specific manner. Integration of cellular abundance and gene expression pinpoints nuclear factor kappa B signaling in neurons as a marker for cellular vulnerability. We also highlight the conservation of cell-type-specific transcriptional patterns between Drosophila and human postmortem brain tissue. Overall, our results create a resource for dissection of dynamic, age-dependent gene expression changes at cellular resolution in a genetically tractable model of tauopathy.","journal":"eLife","year":2023,"id":341112,"datarank":0.5572486314604866,"base_score":2.772588722239781,"endowment":2.772588722239781,"self_citation_contribution":0.41588830833596724,"citation_network_contribution":0.1413603231245194,"self_endowment_contribution":0.41588830833596724,"citer_contribution":0.1413603231245194,"corpus_percentile":null,"corpus_rank":null,"citation_count":15,"citer_count":11,"citers_with_citation_signal":10,"citers_with_endowment":10,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9512,"is_data_producer":true,"deposit_databanks":{"GEO":["GSE138852","GSE107451","GSE142789"]},"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1011430,"name":"Jennifer Deger","orcid":"0000-0003-2208-3348","position":1,"is_corresponding":false},{"id":353011,"name":"Hui Ye","orcid":"0000-0003-3965-9702","position":2,"is_corresponding":false},{"id":288607,"name":"Caiwei Guo","orcid":"0000-0002-9975-9732","position":3,"is_corresponding":false},{"id":40852,"name":"Justin Dhindsa","orcid":"0000-0003-2963-0447","position":4,"is_corresponding":false},{"id":465426,"name":"Brandon Pekarek","orcid":"0000-0001-8785-4196","position":5,"is_corresponding":false},{"id":234498,"name":"Rami Al‐Ouran","orcid":null,"position":6,"is_corresponding":false},{"id":110460,"name":"Zhandong Liu","orcid":"0000-0002-7608-0831","position":7,"is_corresponding":false},{"id":585516,"name":"Ismael Al‐Ramahi","orcid":"0000-0002-1275-1114","position":8,"is_corresponding":false},{"id":585517,"name":"Juan Botas","orcid":"0000-0001-5476-5955","position":9,"is_corresponding":false},{"id":232932,"name":"Joshua M.
