The mysterious trace amines: Protean neuromodulators of synaptic transmission in mammalian brain

  • Trace amines are structurally related compounds found endogenously in the brain and peripheral nervous system of mammals.
  • Metabolicially related to the neurotransmitters norepinephrine, seratonin, and dopamine.
  • Some are synthesized by parent amine neurotransmitter systems, others have their own unique systems.
  • A large amount of research indicates that trace amines coordinate biogenic synaptic physiology.
  • They mimic the presynaptic amphetamine-like effects of biosynthesis, reuptake, and release of catecholamines and indolamines at high concentrations.
  • At low concentrations, they have postsynamptic effects which potentiate the activity of seratonin and dopamine.
  • Trace amine-specific receptors are proven to exist because of their electrophysiological effects that oppose other neurotransmitters.
  • Although several trace amine receptor sites have been studied in detail, their mechanisms of action on indolamine and caecholamine synaptic physiology remains unclear due to the absence of cloned receptor protein.
  • The newly discovered family of G protein-coupled receptors responsive to many trace amines, including illegal psychotropic drugs such as LSD, have prompted research into their synaptic physiology and role in human disorders involving cognition and affect.
