Tachykinin immunoreactivity is found in a ventromedial spinal
plexus in the lamprey. Neurons in this plexus project bilaterally and
are thus in a position to modulate locomotor networks on both sides of
the spinal cord. We have examined the effects of the tachykinin
substance P on NMDA-evoked locomotor activity. Brief (10 min)
application of tachykinin neuropeptides results in a prolonged
concentration-dependent (>24 hr) modulation of locomotor activity,
shown by the increased burst frequency and more regular burst activity.
These effects are blocked by the tachykinin antagonist spantide II.
There are at least two phases to the burst frequency modulation. An
initial phase (~2 hr) is associated with the protein kinase C-dependent potentiation of cellular responses to NMDA. The
long-lasting phase (>2 hr) appears to be protein synthesis-dependent,
with protein synthesis inhibitors causing the increased burst frequency to recover after washing for 2-3 hr. The modulation of the burst regularity is caused by a separate effect of tachykinins, because unlike the burst frequency modulation it does not require the modulation of NMDA receptors for its induction and is blocked by H8, an
inhibitor of cAMP- and cGMP-dependent protein kinases. The effects of
substance P were mimicked by the dopamine D2 receptor antagonist
eticlopride. The effects of eticlopride were blocked by the tachykinin
antagonist spantide II, suggesting that eticlopride may endogenously
release tachykinins. Because locomotor activity in vitro
corresponds to that during swimming in intact animals, we suggest that
endogenously released tachykinins will result in prolonged modulation
of locomotor behavior.
