Published by John Wiley & Sons Ltd.Previously, we found that age-dependent accumulation of beta-amyloid is not sufficient to cause synaptic decline. Late-endocytic organelles (LEOs) may be driving synaptic decline as lysosomes (Lys) are a target of cellular aging and relevant for synapses. We found that LAMP1-positive LEOs increased in size and number and accumulated near synapses in aged neurons and brains. LEOs' distal accumulation might relate to the increased anterograde movement in aged neurons. Dissecting the LEOs, we found that late-endosomes accumulated while there are fewer terminal Lys in aged neurites, but not in the cell body. The most abundant LEOs were degradative Lys or endolysosomes (ELys), especially in neurites. ELys activity was reduced because of acidification defects, supported by the reduction in v-ATPase subunit V0a1 with aging. Increasing the acidification of aged ELys recovered degradation and reverted synaptic decline, while alkalinization or v-ATPase inhibition, mimicked age-dependent Lys and synapse dysfunction. We identify ELys deacidification as a neuronal mechanism of age-dependent synapse loss. Our findings suggest that future therapeutic strategies to address endolysosomal defects might be able to delay age-related synaptic decline.iNOVA4Health - pólo NMSNOVA Medical School|Faculdade de Ciências Médicas (NMS|FCM)RUNBurrinha, TatianaCunha, CésarHall, Michael J.Lopes-da-Silva, MafaldaSeabra, Miguel C.Guimas Almeida, Cláudia2023-07-12T22:16:20Z2023-082023-08-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10362/155155eng1398-9219PURE: 62439022https://doi.org/10.1111/tra.12889info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-03-11T05:37:38Zoai:run.unl.pt:10362/155155Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:55:56.049691Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
