The effects of extracellularly applied recombinant human interleukin-2 (rhIL-2) on the gamma-aminobutyric acid (GABA)-induced Cl- current recorded from identified neurons (R9 and R12) of Aplysia kurodai were investigated with conventional voltage-clamp and pressure ejection techniques. Bath-applied rhIL-2 (10-40 U/ml) reduced the GABA-induced current in the neurons without affecting resting membrane conductance and the holding current. The suppressing effect of rhIL-2 on the current was completely reversible. Heat-inactivated rhIL-2 was without effect. These results suggest that the immunomodulator IL-2 can modulate the GABA-induced response in the nervous system.
