Characterisation of chicken viperin

Area of Science:

• * Immunology and Virology
• * Molecular Biology and Poultry Health

Background:

• * Interferon (IFN) pathways are critical for antiviral defense, stimulating genes that inhibit viral replication.
• * Interferon-stimulated genes (ISGs) are vital for controlling viral infections, but their characterization in chickens is limited.
• * Viperin, an ISG found in mammals, plays a significant role in antiviral protection and may offer similar benefits to chickens.

Purpose of the Study:

• * To identify and characterize chicken viperin (ch-viperin) as a potential antiviral factor.
• * To investigate the expression patterns of ch-viperin in response to viral stimuli in chickens.
• * To provide foundational data for developing targeted antiviral strategies in poultry.

Main Methods:

• * Identification and sequencing of chicken viperin (ch-viperin).
• * In vitro analysis of ch-viperin gene expression upon stimulation with viral signature molecules.
• * In vivo assessment of ch-viperin upregulation following viral infection in chickens.

Main Results:

• * Chicken viperin (ch-viperin) was successfully identified.
• * ch-viperin expression was significantly upregulated in response to specific viral molecular patterns.
• * In vivo studies confirmed viperin upregulation during actual viral infections in chickens.

Conclusions:

• * Chicken viperin is an interferon-stimulated gene (ISG) with antiviral properties.
• * ch-viperin expression is induced by viral infection, highlighting its role in the chicken's innate immune response.
• * These findings support targeting ch-viperin for novel antiviral interventions in poultry health.
