Inflammatory microenvironment and human papillomavirus-induced carcinogenesis

Area of Science:

• Oncology
• Immunology
• Virology

Background:

• Infectious agents contribute significantly to the global cancer burden, with persistent infections being a major risk factor.
• Chronic inflammation, a hallmark of persistent infections, plays a crucial role in cancer development and progression.
• Viral oncoproteins can alter cellular pathways, promoting tumorigenesis and contributing to cancer development.

Purpose of the Study:

• To review the role of the inflammatory microenvironment in Human Papillomavirus (HPV)-induced carcinogenesis.
• To explore the involvement of immune molecules and microRNAs in HPV-related cancer development.
• To investigate the mechanisms of immune molecule and microRNA delivery via microvesicles in HPV carcinogenesis.

Main Methods:

• Literature review focusing on basic, clinical, and epidemiological studies.
• Analysis of cellular pathways modified by persistent infections and viral oncoproteins.
• Examination of the immune response in the context of chronic infection and cancer.

Main Results:

• Persistent infections induce chronic inflammation, leading to tissue damage and impaired tumor surveillance.
• Deregulated immune responses promote carcinogenesis by selecting for aggressive tumor phenotypes.
• Microenvironment inflammation is critical in HPV-induced carcinogenesis, involving specific immune molecules and microRNAs.

Conclusions:

• Chronic inflammation driven by persistent infections like HPV is a key factor in cancer development.
• Immune molecules and microRNAs, delivered via microvesicles, are significant players in the HPV carcinogenesis inflammatory microenvironment.
• Understanding these mechanisms can inform strategies for cancer prevention and treatment.
