Abstract
A family of peptides with the carboxy-terminus Arg-Phe-amide has been localized to specific subpopulations of neurons in every cnidarian species examined. These neurons are typically sensory in character or are associated with smooth muscle. Although a transmitter role for these peptides has been suggested for anthozoans at neuromuscular synapses, no such evidence is available for hydrozoans. Instead there is evidence that RF-amides can be modulators of neuronal activity which takes the form of a biphasic (inhibitory then excitatory) response in vivo, while in vitro only the inhibitory response is seen. Voltage clamp studies of identified motor neurons showed large, transitory outward currents when Pol-RF-amide peptide was applied.
