Role of cholinoceptors recycling in short-term potentiation of cholinosensitivity of command neurons in edible snail.

摘要

Exocytosis inhibitor Exo 1, dynamin inhibitory peptide (inhibitor of endocytosis), and colchicine disturb short-term potentiation of cholinosensitivity of defensive behavior command neurons in edible snail induced by rhythmic electrical orthodromic stimulation. We hypothesize that the short-term potentiation of cholinosensitivity in the extra-synaptic membrane develops due to incorporation of extra cholinoceptors into neuron plasmalemma as a result of enhanced recycling of the internalized cholinoceptors with participation of microtubules.
