Mechanistic description

ADCY8 may specifically tag synapses involved in spatial navigation memories through localized cAMP signaling, creating dedicated ‘navigation synapses.’ Therapeutic enhancement of this synaptic tagging could selectively strengthen spatial memory circuits without affecting other memory systems.

Mechanism / pathway

  1. ADCY8
  2. memory and navigation

Evidence for (2)

  • Ca(2+)-stimulated ADCY1 and ADCY8 regulate distinct aspects of synaptic and cognitive flexibility.

    PMID:37465213 2023 Front Cell Neurosci

  • Jejunal long noncoding RNAs are associated with glycemic control via gut-brain axis after bariatric surgery in diabetic mice.
