Aging impairs the immune system, increasing susceptibility to infections and diseases. Research highlights age-related changes in T cells, B cells, and skin immunity, affecting adaptive capabilities.

Area of Science:

  • Immunology
  • Gerontology
  • Dermatology

Background:

  • The aging process, known as immunosenescence, significantly impacts the immune system's function.
  • Age-related immune alterations can lead to increased susceptibility to infections, autoimmune diseases, and malignancies.

Purpose of the Study:

  • To summarize age-related changes in the immune system, focusing on the skin immune system.
  • To review the current understanding of immunosenescence and its implications.

Main Methods:

  • Literature search of MEDLINE and institutional libraries.
  • Review of relevant articles on immunosenescence and related keywords.

Main Results:

  • Aging alters T cells, shifting them to a memory phenotype with reduced proliferative response and diversity.

  • B cell diversity declines with age, impacting responses to infections and vaccinations.
  • Skin-associated immune cells like Langerhans cells decrease, reducing sensitization rates, while macrophages and keratinocytes also show age-related changes.

    • Conclusions:

    • The skin immune system's adaptive capacity diminishes with age.
    • Interventions targeting age-related immune dysfunctions are under investigation to promote healthy aging.
