Description

The study demonstrates that presenilin knockout leads to decreased drebrin A at synapses, but the mechanistic pathway connecting presenilin function to drebrin A regulation remains unexplained. Understanding this mechanism is crucial for identifying therapeutic targets in early AD pathogenesis.
