Cell Kinetics in the Adult Neurogenic Niche and Impact of Diet-Induced Accelerated Aging. Li N, Li Y, Li LJ, Zhu K, Zheng Y, Wang XM. You can, however, use zebrafish to investigate certain disease phenotypes that are associated with AD. The emerging use of the zebrafish model in neurological and neurodegenerative human diseases (such as PD, autism, Huntington’s disease, and Alzheimer’s disease) was described by Xi et al. … Zebrafish possess genes orthologous to those mutated in familial Alzheimer’s disease and research using zebrafish has revealed unique characteristics of these genes that have been difficult to observe in rodent models. Xia W (2010) Exploring Alzheimer’s disease in zebrafish. Researchers at the University of Alberta are using these fish to study the destructive work of amyloid beta; a protein that piles up inside brain cells and eventually kills them. The consensus today is that Alzheimer’s disease develops from multiple factors such as genetics, lifestyle and the environment. COVID-19 is an emerging, rapidly evolving situation. The basic brain structure of the zebrafish is also conserved when compared to the mammalian brain. 2017 Apr;28(2 and 3-Spec Issue):179-186. doi: 10.1097/FBP.0000000000000284. Finally, the ability to manipulate gene expression has broad usefulness in the study of modeling human disease, including dementia. Role in Alzheimer’s and fibrillization. Their ability to regenerate neurons comes from progenitor cells. Zebrafish possess genes orthologous to those mutated in familial Alzheimer’s disease and research using zebrafish has revealed unique characteristics of these genes that have been difficult to observe in rodent models. Finally, the ability to manipulate gene expression has broad usefulness in the study of modeling human disease, including dementia. -, Hamley IW. Alteration of functional connectivity in patients with Alzheimer's disease revealed by resting-state functional magnetic resonance imaging. Zebrafish possess genes orthologous to those mutated in familial Alzheimer's disease and research using zebrafish has revealed unique characteristics of these genes that have been difficult to observe in rodent models. The utility of the zebrafish model in conditioned place preference to assess the rewarding effects of drugs. NIH The concentration of miRNA-132 is also reduced in the brains of patients with Alzheimer's disease. (β-amyloid, Aβ), which is thought to play a central role in the pathogenesis of Alzheimer's disease (AD), also has an important effect on the development and progression of AD. Alzheimer's disease has reached epidemic proportions in western society. Neural Regen Res. CNS Neurol Disord Drug Targets. Zebrafish brains offer clues to treating Alzheimer’s One of the defining traits of Alzheimer’s diseaseis the accumulation of amyloid-beta aggregates in the brain. 2012;112:5147–5192. -, Eddins D, Cerutti D, Williams P, Linney E, Levin ED. Through knocking-in APP gene in animals, numerous transgenic AD models have been set up for the investigation of the J Neurochem. And yet, considerable debate persists on the role of peptide aggregates of amyloid-β (Aβ)—that form plaques in the brains of Alzheimer’s patients. Zebrafish Help to Unravel Alzheimer’s Disease. Alzheimer’s disease (AD) is a chronic neurodegenerative disease associated with progressive cognitive decline. 2018 May;115:61-68. doi: 10.1016/j.neuint.2018.02.002. Key words. DZNE researcher Caghan Kizil explained that most Alzheimer’s studies looked for ways to stop the death of brain cells. NLM Key findings. In this review we give an overview of how the zebrafish has been used to study Alzheimer's disease. 2019 Jun;14(6):1037-1045. doi: 10.4103/1673-5374.250625. Glutamate receptor delocalization in postsynaptic membrane and reduced hippocampal synaptic plasticity in the early stage of Alzheimer's disease. Biochim Biophys Acta 1812: 346–352. A simplified comparison of the effects of Alzheimer’s disease on neural stem cell plasticity in mouse and zebrafish. The main genes involved in human AD have homologous counterparts in zebrafish and have conserved function. Zebrafish may be a particular powerful model for the study of human disease because many cellular processes are conserved throughout vertebrate evolution, including the corresponding disease genes. USA.gov. There is a specific need to elucidate and improve the treatments available, not only to alleviate the symptoms related to dementias such as Alzheimer’s but also to prevent the formation of the disease. Relationships with other terms of … The concentration of miRNA-132 is also reduced in the brains of patients with Alzheimer's disease.
