Protein kinase C blocker chelerythrine prevented the increase in quantal content of single and rhythmic evoked end-plate potentials after disinhibition of L-type Ca2+-channels with paxillin. Phorbol ester increased quantal content of single end-plate potentials and changed rhythmic activity of mouse motor synapses. The effects of phorbol ester were to a(More)
Blocker of presynaptic protein kinase C isoforms, GF109203X, reduced quantal content of single and rhythmic evoked end-plate potentials. The increase in quantal content of single potentials under the effect of 4- aminopyridine was neutralized by 75% under the effect of L-type Ca2+-channel blocker nitrendipine and completely returned to the control level(More)
