Article Citation - WoS: 2Citation - Scopus: 3Magnetic Levitational Assembly of Differentiated Sh-Sy5y Cells for Aβ-Induced 3d Alzheimer's Disease Modeling and Curcumin Screening(Wiley-v C H verlag Gmbh, 2025) Bilginer-Kartal, Rumeysa; Arslan-Yildiz, AhuAlzheimer's disease is one of the prevalent neurodegenerative diseases and is characterized by amyloid beta aggregate (A beta) accumulation. This study reports an A beta 1-42 induced 3D Alzheimer's disease modeling utilizing differentiated SH-SY5Y spheroids, which is carried out by Magnetic levitation approach, and the neuroprotective effect of Curcumin is further investigated on this model. For this purpose, SH-SY5Y spheroids are differentiated using Retinoic acid-Brain-derived neurotrophic factor sequentially during 3D cell culture. Differentiated spheroids maintained high viability and exhibited significant neuronal characteristics, as evidenced by increasing beta-III tubulin and NeuN expressions. 3D Alzheimer's disease model formation and neurotoxicity of A beta 1-42 aggregates are investigated on un-/differentiated spheroids, resulting in 65% and 51% cell viability, respectively. Characterization of the 3D Alzheimer's disease model is done by immunostaining of Choline acetyltransferase to investigate cholinergic neuron activity loss, showing a 2.2 decrease in fluorescence intensity. Further, Curcumin treatment on the 3D Alzheimer's disease model resulted in augmenting cell viability, confirming neuroprotective effect of Curcumin on A beta 1-42 induced Alzheimer's disease model. This study highlighted the magnetic levitation-based fabrication of A beta 1-42-induced 3D Alzheimer's disease model successfully, offering a promising experimental platform for other neurodegenerative disease research and potential clinical applications.
