  • Title: Effect of PAR1 agonist on acetylcholine secretion in a newly formed neuromuscular synapse in mice.
    Author: Balezina OP, Gerasimenko NY, Strukova SM.
    Journal: Bull Exp Biol Med; 2007 Nov; 144(5):653-6. PubMed ID: 18683487.
    Abstract:
    Peptide agonist of PARI in a concentration of 10 microM significantly facilitated neuromuscular transmission in newly formed synapses in mice. The absence of changes in the amplitude of miniature end-plate potentials attests to presynaptic mechanism of the effect of PAR1 agonist. The effect of the peptide was blocked by protein kinase A inhibitor H89 (1 microM). Blockade of inositol-1,4,5-trisphosphate receptors with 2-amino-ethoxydiphenylborate (30 microM) did not prevent the effects of PARI agonist. Inhibition of protein kinase C with bisindolylmaleimide (1 microM) facilitated neuromuscular transmission in newly formed synapses. Protein kinase C inhibition was associated with reversal of the object of PARI agonist: transmission inhibition instead of facilitation.
