Changes in Adaptive Immunity in Autoimmune Diseases and Aging: Shared Features, Key Differences, and Implications for...

Area of Science:

• Immunology
• Gerontology
• Autoimmunity

Background:

• Immunologically vulnerable populations (IVP) face heightened infection risks due to immune dysregulation.
• Autoimmune diseases (AI DIS) and aging represent the most common IVP groups.
• Immune aging is increasingly linked to the development and progression of autoimmune conditions.

Purpose of the Study:

• To review adaptive immune dysregulation in AI DIS and older adults.
• To critically analyze similarities, differences, and interrelations between these two IVP groups.
• To examine their immune responses to infection and vaccination.

Main Methods:

• Literature review and synthesis of existing research.
• Comparative analysis of adaptive immunity in AI DIS and aging.
• Examination of immune response data related to infection and vaccination.

Main Results:

• Both AI DIS and aging exhibit distinct yet overlapping patterns of adaptive immune dysregulation.
• Evidence suggests immune aging can exacerbate or trigger autoimmune responses.
• Understanding these interrelations is crucial for managing infection and vaccination efficacy in IVP.

Conclusions:

• Adaptive immune dysregulation is a key feature of both AI DIS and aging.
• The interplay between immune aging and autoimmunity requires further investigation.
• Targeted strategies are needed to improve infection and vaccination outcomes for these vulnerable populations.
