DHA (docosahexaenoic acid)

Intracellular DHA delivery promote homeostatic synaptic plasticity and neuroprotection in the hippocampus by increasing cAMP/PKA/CREB signaling

  • BDNF-induced synaptogenesis is enhanced by intracellular DHA delivery to neural stem/progenitor cells (NSPCs)
  • Increased CREB function (phosphorylation) may protect neurons from glutamate excitoxicity and neuroinflammation via phosphorylation of the NMDA receptor. [1]
    • mBDNF transactivate the TrkB receptor and decrease the excitability of GABAergic interneurons. [2]

Neuroprotective properties of DHA

  • DHA is neuroprotective and controlled by the P2X7 purinoreceptor. [3]
  • DHA exert proneurogenic functions on activated microglia cells. [4]

DHA and vitamin D control of serotonin synthesis

DHEA (N-docosahexaenoyl ethanolamide)

  • Ethanolamide metabolite of DHA.
  • Derivative of anandamide.
  • A synaptogenic endocannabinoid with antiglutamatergic and neuroprotective effects that induce synaptogenesis in vivo. [5]


  • Serotonin conjugate of DHA. [6]


  • Dopamine conjugate of DHA. [7]
