Liberación consistente de virus adenoasociados a través de la inyección lateral de la vena de la cola en ratones adultos

Overview

This article presents an optimized protocol for performing lateral tail-vein injections in adult mice to administer adeno-associated virus (AAV). It also outlines various assays to evaluate AAV transduction efficiency.

Key Study Components

Area of Science

• Gene therapy
• Neuromuscular disorders
• Viral vector administration

Background

• Gene therapies are being developed for muscular dystrophies and neuromuscular disorders.
• Improved viral and non-viral vectors enhance safety and efficiency of therapies.
• Mouse models are essential for testing these gene therapies.
• Lateral tail-vein injections are a common method for systemic administration of AAV.

Purpose of Study

• To facilitate the administration of AAV for gene therapy research.
• To improve the reliability of AAV transduction assessments.

Methods Used

• Preparation of the mouse using a restrainer tube.
• Dilating tail veins with warm water.
• Injecting AAV solution into the lateral tail vein.
• Post-injection care to minimize bleeding.

Main Results

• Successful AAV administration was achieved through optimized injection techniques.
• Histological imaging confirmed widespread transduction in liver and quadriceps tissues.
• tdTomato expression indicated effective delivery of the AAV vector.
