Global virus outbreaks: Interferons as 1st responders.

Area of Science:

• Virology
• Immunology
• Infectious Diseases

Background:

• Increasing global outbreaks of emerging, re-emerging, and zoonotic viral infections (e.g., SARS, Ebola, Zika, H5N1) pose significant pandemic risks.
• The absence of specific vaccines or antivirals for many novel viruses highlights the urgent need for broad-spectrum antiviral agents.
• Type I interferons (IFNs) possess known direct antiviral activities against both DNA and RNA viruses.

Purpose of the Study:

• To evaluate type I interferons (IFNs) as broad-spectrum antiviral candidates.
• To highlight the potential of IFNs-α/β in combating emerging viral infectious diseases.

Main Methods:

• Review of the direct antiviral effects of type I IFNs on viral replication cycles.
• Analysis of the immunomodulatory functions of type I IFNs in activating immune cells for virus clearance.

Main Results:

• Type I IFNs demonstrate direct inhibition of viral replication across various stages.
• Type I IFNs effectively activate immune cell populations crucial for eradicating viral infections.

Conclusions:

• Type I interferons (IFNs), specifically IFNs-α/β, are potent broad-spectrum antivirals.
• IFNs-α/β represent promising therapeutic candidates for managing outbreaks of severe viral infections and potential pandemics.
