Dopaminerjik Homeostasis farelerde yüksek performanslı sıvı Kromatografi analizi ve Synaptosomal dopamin alımı kullanımı tarafından değerlendirilmesi

Overview

This study presents two techniques to investigate dopamine homeostasis in mice: the assessment of dopamine transporter function through synaptosomal dopamine uptake and the analysis of dopamine levels in striatal tissue using high-performance liquid chromatography (HPLC). These methods allow for the evaluation of dopamine tissue content and transporter functionality, especially after in-vivo manipulations.

Key Study Components

Area of Science

• Neuroscience
• Dopamine Transporter Function
• High-Performance Liquid Chromatography (HPLC)

Background

• Dopamine plays a crucial role in various neural functions.
• The dopamine transporter is critical for dopamine reuptake and homeostasis.
