HPV disease transmission protection and control

Area of Science:

• Virology
• Immunology
• Oncology

Background:

• Human papillomaviruses (HPVs) are a diverse group of viruses linked to epithelial diseases, including cancers of the anogenital, oral, and cutaneous sites.
• A subset of mucosal HPVs are oncogenic, contributing to over 200,000 global deaths annually.
• HPVs employ sophisticated mechanisms to evade host immune responses, hindering effective control.

Purpose of the Study:

• To review current knowledge on HPV biology, disease transmission, protection, and control.
• To identify key knowledge gaps in papillomavirus biology, including tissue tropism, cancer progression, and immune response strategies.
• To highlight areas for future research to deepen understanding of these viral pathogens.

Main Methods:

• This is a review article, synthesizing existing research on human papillomaviruses.
• It discusses viral life cycle, protein functions, and host immune responses.
• It analyzes disease transmission, protection, and control strategies.

Main Results:

• HPVs exhibit species and tissue tropism, affecting cutaneous and mucosal epithelia.
• Oncogenic HPVs are responsible for a significant cancer burden worldwide.
• Viral proteins actively disrupt host innate and adaptive immunity, facilitating infection and disease progression.

Conclusions:

• Despite extensive knowledge, critical areas in HPV biology, such as tissue tropism and effective immune strategies against carcinogenic HPV stages, require further investigation.
• Continued research into PV biology offers opportunities for discovery and improved understanding of these pathogens.
• Developing effective control strategies necessitates addressing viral evasion tactics and enhancing host immune responses.
