HPV Infections-Classification, Pathogenesis, and Potential New Therapies.

Area of Science:

• Virology
• Oncology
• Immunology

Background:

• Over 400 human papillomavirus (HPV) types exist, causing significant global health issues, including 5% of all cancers and frequent benign lesions like warts.
• Despite effective prophylactic vaccines for common genital HPV types, the viruses persist due to their resistance to disinfectants and environmental conditions.
• Current treatments focus on lesion removal or immune stimulation, as no drugs inhibit HPV replication.

Purpose of the Study:

• To systematically review HPV classification, structural variations across types, lineages, and sublineages.
• To elucidate the pathogenesis of HPV-induced diseases, emphasizing the role of viral proteins (E6, E7) in lesion development.
• To explore novel therapeutic avenues for HPV infections.

Main Methods:

• Literature review of HPV systematics and structural diversity.
• Analysis of GenBank data for HPV genetic variations.
• Review of scientific literature on HPV pathogenesis and therapeutic strategies.

Main Results:

• Detailed classification of HPV types, lineages, and sublineages based on structural differences.
• Elucidation of the pathogenic mechanisms of HPV, highlighting the oncogenic roles of E6 and E7 proteins.
• Identification of potential therapeutic targets, including viral entry inhibitors and replication blockers.

Conclusions:

• Understanding HPV diversity and pathogenesis is crucial for developing effective treatments.
• Emerging therapies targeting viral replication, entry, and host immune response show promise for HPV infection management.
• Further research into novel therapeutic vaccines and plant-derived compounds could offer new solutions for HPV-related diseases.
