Abstract
Cytomegalovirus (CMV) drives immunosenescence, while its reactivation is associated with inflammation and oxidative stress. This study investigates the interplay between CMV, oxidative stress and inflammation in a cohort of 2065 age-stratified individuals randomly recruited from the general population (RASIG), as part of the MARK-AGE study, to better understand the role of CMV in immunosenescence and its potential impact on age-related diseases. CMV IgG titers were associated with oxidative stress, antioxidant, and inflammatory biomarkers. Stepwise-linear regression identified positive associations with age, BMI, apolipoprotein J (ApoJ/Clu), ceruloplasmin, α-2-macroglobulin, proteasome peptidase activity, and malondialdehyde, and negative associations with α-tocopherol, selenium, and vitamin D. Notably, the associations with ApoJ/Clu and proteasome peptidase activity represent novel findings that point to a potential involvement of proteostasis dysregulation and cellular stress responses in CMV-related immune alterations. Quartile-based analyses revealed significantly lower antioxidant levels (α-tocopherol, selenium, ascorbic acid and vitamin D) and higher oxidative stress markers (plasma 8-isoprostanes, malondialdehyde) in the highest quartile (Q4) compared to lower quartiles. Inflammatory markers (homocysteine, ceruloplasmin and α-2-macroglobulin) ApoJ/Clu and proteasome peptidase activity were elevated in Q4. This group also exhibited a higher prevalence of cardiovascular diseases, hypertension, and diabetes. This study highlights a link between CMV IgG titers, oxidative stress, inflammation, and the prevalence of cardiovascular and metabolic diseases. Our findings suggest that CMV may contribute to immunosenescence through mechanisms involving redox imbalance and dysregulation of protein degradation pathways. Further research is needed to explore the role of CMV reactivation in aging, and its impact on age-related metabolic and cardiovascular diseases.
期刊介绍:
The journal Biogerontology offers a platform for research which aims primarily at achieving healthy old age accompanied by improved longevity. The focus is on efforts to understand, prevent, cure or minimize age-related impairments.
Biogerontology provides a peer-reviewed forum for publishing original research data, new ideas and discussions on modulating the aging process by physical, chemical and biological means, including transgenic and knockout organisms; cell culture systems to develop new approaches and health care products for maintaining or recovering the lost biochemical functions; immunology, autoimmunity and infection in aging; vertebrates, invertebrates, micro-organisms and plants for experimental studies on genetic determinants of aging and longevity; biodemography and theoretical models linking aging and survival kinetics.
