  • Title: Effect of omega-conotoxin GVIA on neurotransmitter release at the mouse neuromuscular junction.
    Author: Protti DA, Szczupak L, Scornik FS, Uchitel OD.
    Journal: Brain Res; 1991 Aug 23; 557(1-2):336-9. PubMed ID: 1684129.
    Abstract:
    The effect of omega-conotoxin GVIA (omega-CgTx) was studied on spontaneous, K(+)-induced and electrically evoked neurotransmitter release at the neuromuscular junction of mouse diaphragm. omega-CgTx decreased the frequency and amplitude of basal and K(+)-induced miniature end plate potentials. This effect was abolished by raising the extracellular Ca2+ concentration. omega-CgTx had no effect on the quantal content of the electrically evoked release in this preparation.
