Метод быстрой циклической вольтамперометрии для прижизненного измерения содержания дофамина в режиме реального времени

Abstract

Данная работа посвящена измерению дофамина у свободно перемещающихся крыс с помощью методы быстрой циклической вольтамперометрии. Дофамин - ключевой моноамин, участвующий в вознаграждении, обучении, памяти, агрессии и различных других функциях. Следовательно, нарушение регуляции дофаминергической системы может привести к серьезным негативным последствиям во многих аспектах человеческой жизни. Для более эффективной коррекции патологии дофаминергической системы крайне важно иметь представление об уровне дофамина в течение дня. Метод циклической вольтамперометрии с быстрым сканированием позволяет получить вольтамперограмму, которая впоследствии может быть преобразована в концентрацию дофамина с использованием внешних стандартов. Цель работы: Модифицировать метод БСЦВА для прижизненного измерения дофамина у свободно перемещающегося животного. Задачи: 1. Модифицировать конструкцию для БСЦВА для применения на свободно перемещающихся животных. 2 Апробировать модифицированную конструкцию на интактных животных в условиях стандартной электрической стимуляции. Работа была выполнена в Лаборатории нейрохимии Физиологического отдела им. И.П. Павлова ФГБНУ ИЭМ. В результате проделанной работы в лаборатории был спроектирован прибор Теле-ВольтАмперметр, позволяющий измерять концентрацию дофамина в субсекундном масштабе у свободно перемещающихся животных.

This work is devoted to the measurement of dopamine in freely moving rats using the methods of fast cyclic voltammetry. Dopamine is a key monoamine involved in reward, learning, memory, aggression, and various other functions. Consequently, a violation of the regulation of the dopaminergic system can lead to serious negative consequences in many aspects of human life. For a more effective correction of the pathology of the dopaminergic system, it is extremely important to have an idea of the level of dopamine during the day. The method of cyclic voltammetry with fast scanning allows you to obtain a voltammogram, which can subsequently be converted into a dopamine concentration using external standards. The purpose of the work: To modify the FSCV method for lifetime measurement of dopamine in a freely moving animal. Tasks: 1. Modify the design for the FSCV for use on freely moving animals. 2 To test the modified design on intact animals under the conditions of standard electrical stimulation. The work was performed in the Laboratory of Neurochemistry of the I.P. Pavlov Physiological Department of the IEM FSBI. As a result of the work done, a Tele-voltammeter device was designed in the laboratory, which allows measuring the concentration of dopamine on a subsecond scale in freely moving animals.
