登革热病毒诱发急性病毒性脑炎样疾病的鼠害模型

Overview

This article presents a protocol for creating an immunocompetent ICR murine model to study dengue virus-induced neuropathy. The model allows for monitoring acute viral encephalitic disorders in vivo.

Key Study Components

Area of Science

• Neuroscience
• Infectious Diseases
• Animal Models

Background

• Dengue virus can cause neurological complications.
• Existing models may not effectively represent neuropathogenesis.
• The ICR murine model provides a new platform for research.
• Low viral titer infection is utilized for better disease induction.

Purpose of Study

• To develop a reliable model for studying dengue virus effects on the central nervous system.
• To facilitate screening of viral and host factors involved in neuropathogenesis.
• To monitor disease progression using standardized scoring methods.

Methods Used

• Infection of immunocompetent ICR suckling mice.
• Dilution of non-adapted dengue virus to a specific titer.
• Use of syringes with precise volumes for virus administration.
• Monitoring of disease symptoms and progression.

Main Results

• Successful induction of encephalitic-like disease in mice.
• Establishment of a protocol for future studies on neuropathogenesis.
• Demonstration of the model's utility in screening interventions.
• Standardized scoring system for assessing disease severity.

Conclusions

• The ICR murine model is effective for studying dengue virus neuropathy.
• This protocol can aid in understanding viral and host interactions.
• Future research can build on this model to explore therapeutic options.
