Mechanistic description

Since spatial navigation deficits are early Alzheimer’s symptoms, targeted upregulation of ADCY8 specifically in hippocampal place cells could restore spatial memory encoding. This approach would leverage the evolutionary conservation of memory-based navigation systems identified in migratory species.

Mechanism / pathway

  1. ADCY8
  2. memory and navigation
