Zebrafish and Alzheimer's Disease
We are pleased to highlight a recent publication by Ray et al. (2025) that investigates local genetic covariance between early-onset Alzheimerโs disease (EOAD) and blood lipid traits. We in the Kizil Lab are proud to have contributed to this collaboration, which deepens our understanding of how lipid biology intersects with neurodegenerative risk. ๐ Read the …
We are happy to announce a new preprint from the Kizil Lab, led by first author Elanur Yilmaz, titled โSingleโnucleus multiomics in brains from Hispanic individuals reveal APOEโฮต4โdriven disruption of focal adhesion signaling in the presence of cerebrovascular pathology.โ In this study, our team analyzed 413,175 single nuclei from 52 postmortem brains with high cerebrovascular …
We are excited to share a new preprint from the Kizil Lab titled "APOEโฮต4โinduced Fibronectin at the bloodโbrain barrier is a conserved pathological mediator of disrupted astrocyteโendothelia interaction in Alzheimerโs disease." In this study, we uncover a previously unknown mechanism by which the APOEโฮต4 alleleโone of the strongest genetic risk factors for Alzheimerโs diseaseโdisrupts brain …
We are excited to share our new study on the role of the ABCA7 gene in brain resilience against Alzheimerโs. Published in Cell Genomics, we found that ABCA7 is crucial for maintaining synaptic health by regulating neuropeptide Y (NPY), a key molecule for brain communication and repair. Loss of ABCA7 reduces NPY, weakening the brain's …

We are thrilled to announce our participation in a groundbreaking study in collaboration with Mayo Clinic, now published in Nature Communications. This research looks into the intricate role of blood-brain barrier disruptions in Alzheimerโs disease, leveraging the remarkable capabilities of zebrafish models in combination with vast antemortem and postmortem human brain datasets. The blood-brain barrier …
We discovered a genetic variant that reduces the odds of developing Alzheimerโs disease by up to 70% and may be protecting hundreds of thousands of people from the disease. The discovery of the protective variant, which appears to allow toxic forms of amyloid out of the brain and through theโฏblood-brain barrier, supports emerging evidence that …

We are glad to share our first bioRxiv preprint in 2024. Alzheimer's disease is characterized by cognitive decline and memory loss, and genetic variations in humans are key to understanding it. Our study focused on the ABCA7 gene, which is linked to Alzheimer's risk. We used CRISPR/Cas9 gene editing to create zebrafish with a genetic …

A molecular mechanism that zebrafish brain uses to regenerate neurons after neurodegeneration can help us to cope with Alzheimer's, our recent study shows. Induced neurogenesis could be a therapy option for ameliorating Alzheimer's disease pathology. Our recent publication in Nature Partner Journal Regenerative Medicine addresses whether we can use neurogenesis as a means to counteract …

Our book chapter on 3D hydrogel cultures and modeling Alzheimer's disease is published in Alzheimer's Disease: Methods and Protocols in Methods in Molecular Biology book series. https://link.springer.com/book/10.1007/978-1-0716-2655-9
We are happy to announce that we moved to New York to the Department of Neurology and the Taub Institute in Columbia University Irving Medical Center. We are thrilled to continue and expand on our work in zebrafish on Alzheimerโs disease in the great New York City at this great university! Stay tuned!
