[The cholinoreceptors of the neurons in the edible snail: their identification and plasticity and its regulation by opioids and second messengers]

Abstract

In the paper is presented the review of author's own data on the cholinoreceptors of identified Helix neurons and the regulation of their plasticity. The review contains the following parts: cholinoreceptors identification, their coupling with ionic channels, identification of opioid receptors, modulation of cholinoreceptors by opioids, plasticity of cholinoreceptors, modulation of their plasticity by the second messengers, second messengers involved in a modulation of cholinoreceptors' plasticity by the opiate kappa-agonist bremazocine.
