Engram cells in "AD" mouse with Plaques. This image represents a coronal section of hippocampal dentate gyrus (DG) from a mouse model of early Alzheimer’s disease. These AD mice exhibit severe β-amyloid plaques (red) in the DG at 9-months of age. Using these mice combined with a novel viral strategy, memory engram cells (green) for a contextual fear memory were labeled. |
