{"doi":"10.3390/ijms26168092","title":"Vertebrate and Invertebrate Animal Models for the Study of Down Syndrome","abstract":"Down syndrome (DS) is the most common survivable chromosome trisomy, with an incidence of about 1 in 600–700 births. Consequences of chromosome 21 trisomy include developmental delays, congenital cardiac abnormalities, skeletal abnormalities, and age-related dementia of the Alzheimer’s disease (AD) type. Up to 90% of individuals with DS develop dementia symptoms in their 40s or 50s. Because the biological mechanisms involved in DS-related developmental and age-related pathology are less known, animal models consisting of both lower-order and higher-order animals have been developed. We here review the most pertinent and well-studied DS animal models including models developed in C. elegans, Drosophila, zebrafish, and mice. Molecular pathways involved in DS morbidity that were discovered in animal models will also be discussed.","journal":"International Journal of Molecular Sciences","year":2025,"id":526631,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":3,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9376,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":305914,"name":"Ann‐Charlotte Granholm","orcid":"0000-0002-9685-7599","position":0,"is_corresponding":true}],"reference_count":126,"raw_metadata":null,"created_at":"2026-07-19T02:50:30.402772Z","pmid":"40869415","pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
