Mechanistic description

The complete ADCY8 signaling cascade through PKA to CREB transcriptional activation could be the mechanistic link to long-term spatial memory formation. Selective activation of this pathway during spatial learning phases could enhance memory consolidation for navigation-dependent behaviors in cognitive impairment.

Mechanism / pathway

  1. ADCY8
  2. memory and navigation
