The persistent virome, including viruses like cytomegalovirus, significantly impacts immune aging. This review explores how these lifelong viral infections contribute to the aging of the immune system.
Area of Science:
- Virology
- Immunology
- Microbiome Research
Background:
- The microbiome, including the virome, plays crucial roles in health and disease.
- The virome comprises viruses residing within hosts, including endogenous viral elements and those infecting other microbes.
- These persistent viruses are integral to the host's lifespan and aging process.
Purpose of the Study:
- To review the impact of the persistent latent virome on immune aging.
- To highlight the role of herpesviruses, particularly cytomegalovirus, in modulating immune senescence.
Main Methods:
- Literature review focusing on virome, immune aging, and herpesviruses.
- Analysis of existing research on persistent viral infections and their immunological consequences.
Main Results:
- Persistent viral infections are increasingly recognized as contributors to immune aging.
- Herpesviruses, especially cytomegalovirus, are identified as key modulators of age-related immune decline.
Conclusions:
- The latent virome is a significant factor in the aging of the immune system.
- Understanding the virome's role in immune aging is crucial for developing interventions against age-related diseases.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
