The Way

Non-heated rabbit serum causes massive transmitter release from motor nerve endings. The effect is not observed after heating the serum, in the way usually done to destroy complement. It seems that serum may be acting on the nerve terminals by a mechanism involving the complement system in the absence of antibody.

Endplate Potentials

β-Bungarotoxin (β-BuTX) induces twitching of innervated frog muscle and subsequently blocks transmitter release from motor nerve endings. These actions of β-BuTX are prevented if the nerve-muscle junctions are pretreated with a low concentration of phospholipase A 2 from bee venom. When the Ca 2+ in the external fluid is replaced by Sr 2+ , the phospholipase activity of β-BuTX is negligible and, in these conditions, β-BuTX causes a decrease in the amplitude of endplate potentials but does not go on to block transmitter release completely.

Individual Motor

Latency of release of individual quanta of transmitter was studied at neuromuscular junctions of a crayfish (Procambarus clarkii). Postsynaptic quantal currents were recorded at individual motor nerve endings with a macropatch electrode while the subterminal axon branch was depolarized by current passed through an intracellular microelectrode. For depolarizing currents of moderate size, the latency of transmitter release did not change when the duration of the depolarizing current was altered. Previous studies in which a contrary result was obtained may have been compromised by artefacts or by the sampling methods employed. The present results do not support the hypothesis of a depolarization-induced "repressor" of quantal release.
