Mechanistic description

High-frequency gamma oscillations stimulate activity-dependent release of brain-derived neurotrophic factor (BDNF) from excitatory terminals, activating TrkB receptors on postsynaptic neurons to promote spine stabilization and prevent glutamate receptor internalization. This has the highest druggability potential given extensive TrkB agonist development programs. Critical barrier: BDNF does not cross the blood-brain barrier; systemic TrkB agonists must achieve high CNS penetration, which has historically been the failure mode.

Mechanism / pathway

  1. BDNF (brain-derived neurotrophic factor); NTRK2 (TrkB); CREBBP/EP300 (CREB)
  2. Alzheimer's disease

Evidence for (3)

  • BDNF is necessary for gamma entrainment memory benefits

    PMID:35017363

  • TrkB agonism synergizes with 40 Hz stimulation

    PMID:37129384

  • CREB-dependent transcription identified as critical mediator

    PMID:35921564

Evidence against (2)

  • BDNF does not cross the BBB; CNS penetration is the primary obstacle for all TrkB agonists

    PMID:35017363

  • TrkB is widely expressed; systemic side effects (appetite, weight, sensory neuron growth) require characterization

    PMID:35921564
