Effect of Endogenous Neuropeptide Cycloprolylglycine on GABAA Receptors in Cerebellar Purkinje Cells

Bulletin of Experimental Biology and Medicine Aims and scope

Voltage clamp and concentration-jump methods were employed to examine the effects of endogenous neuropeptide cycloprolylglycine on GABA-activated ionic currents in isolated cerebellar Purkinje cells. In the concentration range of 0.1-10.0 μM, short-term (600 msec) external application of cycloprolylglycine against the background of GABA-evoked current produced no effect on its amplitude. In contrast, application of 1 μM cycloprolylglycine increased current up to 177±15% control level. The development of potentiating effect and return to the control level of ionic current were slow, which was indicative of possible implication of second messenger systems in these processes. Functional augmentation of GABAA receptors under the action of cycloprolylglycine can underlie the established neuroprotective and anxiolytic effects of this endogenous dipeptide.
