Zebrafish as a Model for the Study of Host-Virus Interactions

Area of Science:

• Virology
• Immunology
• Zebrafish Model Systems

Background:

• Zebrafish (Danio rerio) offer optical and genetic advantages for host-pathogen interaction studies.
• Zebrafish possess a vertebrate-type innate and adaptive immunity.
• Spring viraemia of carp virus (SVCV) can infect zebrafish and related cell lines (ZF4, EPC).

Purpose of the Study:

• To establish a simple and efficient model system for studying host-virus interactions.
• To provide detailed protocols for analyzing SVCV infection in zebrafish and cell lines.
• To facilitate functional assays of zebrafish genes in the context of viral infection.

Main Methods:

• Infection of zebrafish embryos and ZF4/EPC cell lines with SVCV.
• Analysis of immune responses using quantitative PCR (qPCR) and RNA sequencing (RNA-Seq).
• Antiviral assays and luciferase assays for host-virus interaction analysis.

Main Results:

• SVCV successfully infects zebrafish embryos and ZF4/EPC cell lines.
• Protocols enable detailed analysis of immune responses and viral propagation.
• The model system is suitable for functional gene assays and antiviral studies.

Conclusions:

• Zebrafish embryos, ZF4/EPC cells, and SVCV provide a robust model for host-virus interaction research.
• Detailed protocols facilitate the study of viral pathogenesis and host immunity.
• This system offers efficient means to address host-virus interactions in a general biological context.
