Gonadotophin-releasing hormone (GnRH) peptide released from the terminal nerve (TN)-GnRH neurones of the dwarf gourami primarily modifies the electrical properties of various neurones, including the TN-GnRH neurones themselves. However, our knowledge on the expression of GnRH receptors (GnRHRs) in the TN-GnRH neurones is still limited. Here, we used the single-cell reverse transcriptase-polymerase chain reaction after whole-cell patch-clamp recording to study the distribution of various GnRHR types expressed in the individual TN-GnRH neurones. We found that TN-GnRH neurones express two of the three types of GnRHRs cloned in the dwarf gourami: GnRHR1-2 and -R2, but not -R1-1. Furthermore, in agreement with our previous findings, all TN-GnRH neurones contained mRNAs of salmon GnRH but not chicken GnRH-II.
