Research Abstract |
To understand fine tuning mechanisms of the central nervous system by peptidergic neurons, we investigated the excitation-secretion relationship of single peptidergic neuron using a primary culture system of isolated fish terminal nerve (TN)-gonadotropin releasing hormone (GnRH) neuron and gene transfer of exogenous genes by single cell electroporation. As a result, we enabled measurement of the movement of secretory vesicles and their exocytotic events from the subcellular region of single peptidergic neuron. We also analyzed the ionic mechanisms of the firing pattern control of TN-GnRH neurons that are the origin of exocytosis of GnRH peptide.
