Adult transgenic zebrafish with her4.1-driven human FMNL2 overexpression show higher FMNL2 immunoreactivity, reduced BLBP–ZO1 overlap, fewer normalized SV2 puncta, and increased microglial activation.
- Why it matters: Sustained FMNL2 elevation is linked to Alzheimer’s disease and cerebrovascular pathology, but its long-term brain and behavioral consequences are unclear.
- What they did: The authors created a transgenic Danio rerio line expressing human FMNL2 under the her4.1 promoter and assessed adult brain histology and behavior at baseline and after acute amyloid-beta42 exposure using immunolabeling and the novel tank test and free-movement pattern Y-maze.
- The result: Baseline FMNL2 overexpression produced histological changes in the same direction as acute Aβ42 in wild-type fish, with no additional histological effects after Aβ42 in the overexpression background, and increased composite boldness in the novel tank test.
