Cells . 2023 Jan; 12(2). PMID: 36672153
The precision of colocalization analysis is enhanced by 3D and is potentially more accurate than 2D. Even though 3D improves the visualization of colocalization analysis, rendering a colocalization model may...

ACS Chem Neurosci . 2022 Sep; 13(19):2913-2923. PMID: 36095282
Since amyloid β (Aβ) oligomers are more cytotoxic than fibrils, various dimer models have been synthesized. We focused on the C-terminal region that could form a hydrophobic core in the...
