Human Endogenous Retroviruses and Diseases.

Area of Science:

• Genomics
• Immunology
• Molecular Biology

Background:

• Human endogenous retroviruses (HERVs) constitute approximately 8% of the human genome.
• Initially dismissed as genomic fossils, HERVs are now recognized for their dynamic roles in gene expression, immunity, and homeostasis.
• HERVs influence biological processes through epigenetic regulation, molecular mimicry, and viral mimicry.

Purpose of the Study:

• To synthesize the molecular architecture and evolutionary history of HERVs.
• To emphasize tissue-specific expression patterns of HERVs.
• To delineate the pathogenic roles of HERVs in various diseases and discuss therapeutic strategies.

Main Methods:

• Review of existing literature on HERV molecular biology, evolution, and disease association.
• Analysis of HERV expression patterns across different tissues.
• Exploration of current and emerging therapeutic strategies targeting HERVs.

Main Results:

• HERVs possess structural components like long terminal repeats and viral genes that function as regulatory elements and antigen sources.
• Dysregulation of HERVs is linked to diseases such as cancer, autoimmune conditions, and neurodegenerative disorders.
• Challenges in HERV detection, quantification, and understanding causal links to disease persist.

Conclusions:

• HERVs are crucial players in both physiological regulation and disease pathogenesis.
• Targeting HERVs offers potential for novel biomarkers and therapeutic interventions in precision medicine.
• Further research is needed to overcome technical challenges and fully realize the clinical potential of HERVs.
