The Role of the DNA Damage Response throughout the Papillomavirus Life Cycle

Area of Science:

• Molecular Biology
• Virology
• Genetics

Background:

• The DNA damage response (DDR) is crucial for maintaining genomic stability by detecting and repairing DNA lesions.
• Viruses often exploit host cell machinery, including DDR pathways, to facilitate their replication.
• Papillomaviruses (PVs) are known to interact with host cell processes.

Purpose of the Study:

• To review the papillomavirus (PV) life cycle.
• To highlight how PVs recruit and engage the DNA damage response (DDR) pathways.
• To elucidate the mechanisms by which PVs manipulate DDR for productive infection.

Main Methods:

• Literature review of existing research on PVs and DDR.
• Analysis of current knowledge on PV-DDR interactions.
• Synthesis of information on the PV life cycle in relation to DDR.

Main Results:

• PVs actively recruit and utilize components of the host cell's DDR machinery.
• DDR factors are manipulated by PVs to support viral DNA replication and genome maintenance.
• The interaction between PVs and DDR is essential for the completion of the PV life cycle.

Conclusions:

• Papillomaviruses have evolved sophisticated strategies to co-opt the DNA damage response.
• Understanding PV-DDR interactions is key to comprehending viral pathogenesis and developing antiviral therapies.
• Targeting the DDR manipulation by PVs could offer novel therapeutic avenues.
