Mesh-like Scaffold is Disordered in Alzheimer’s-affected cells

A cell nucleus from a normal, healthy brain is shown at left. The lamin nucleoskeleton forms the perimeter around the nucleus. By contrast, tunnel-like anomalies are evident in the nucleus of the Alzheimer's disease-affected cell shown at right.

A new finding offers a insight into one of the earliest biological events of Alzheimer’s disease and is expected to open new avenues of study. Neuronal cell death in Alzheimer’s disease is linked to disruption of a lamin nucleoskeleton that surrounds the nucleus of the cells...
