A Second Career for p53 as A Broad-Spectrum Antiviral?

Area of Science:

• Molecular Biology
• Immunology
• Virology

Background:

• The p53 protein, recognized for its tumor suppressor functions, has a less-explored role in combating viral infections.
• Despite its discovery linked to a viral protein, research has primarily focused on p53's anticancer properties.

Purpose of the Study:

• To highlight the critical role of p53 in host antiviral immune responses.
• To propose that p53 should be recognized as a "virus suppressor" alongside its established function as a tumor suppressor.
• To advocate for increased research into p53's antiviral functions to enhance pandemic preparedness.

Main Methods:

• This is a perspective piece, synthesizing existing scientific literature.
• It reviews the diverse mechanisms viruses employ to counteract p53-mediated defenses.
• It analyzes the implications of p53's role in viral infections.

Main Results:

• p53 is a vital component of the host immune system against a wide range of viral pathogens.
• Viruses have independently evolved sophisticated strategies to inhibit or evade p53 activity.
• The extensive viral countermeasures against p53 underscore its significance in antiviral defense.

Conclusions:

• p53's multifaceted role extends beyond tumor suppression to include potent antiviral activity.
• Understanding and leveraging p53's antiviral functions are essential for developing effective strategies against viral pandemics.
• Further research into p53-virus interactions can improve global readiness for future infectious disease outbreaks.
