A Review on Genetic Epidemiology of Host Genetic Structure, Viral Persistence, and Immunological Escape in HPV-Mediated Cervical Carcinogenesis

Review Article

Abstract

Persistent infection with high-risk human papillomavirus genotypes is regarded as the primary etiological driver of cervical neoplasia, yet the vast majority of exposures result in transient subclinical infections that are successfully cleared by host defenses. This biological discrepancy suggests that viral exposure alone is insufficient for oncogenesis, highlighting host genetic susceptibility as a critical mediator of persistence and malignant progression. Inherited variations within the human leukocyte antigen complex, particularly class II loci such as HLA-DRB1 and HLA-DQB1, heavily influence the efficacy of viral antigen presentation and subsequent cell-mediated immune responses. Similarly, polymorphisms in innate immune receptors, cytokine signaling networks, DNA repair mechanisms, and cell cycle checkpoints dictate the microenvironmental conditions that either facilitate viral clearance or permit genomic integration and cellular transformation. In immunocompromised populations, particularly HIV-coinfected cohorts, the pharmacological administration of highly active antiretroviral therapy exerts a profound, though complex, influence on the local microenvironment, altering mucosal CD4+ T-cell reconstitution and modulating viral clearance kinetics. Combining genetic epidemiological data with host-virus interaction models reveals a polygenic architecture of disease risk, modified by both environmental cofactors and viral genomic diversity. Characterization of these host genetic determinants provides a theoretical foundation for refining clinical risk stratification, optimizing therapeutic vaccine interventions, and developing personalized screening algorithms
