Sex and gender affect immune aging

Area of Science:

• Immunology
• Gerontology
• Sociology

Background:

• Biological sex differences influence immune responses.
• Gender, as a social construct, also significantly shapes immune aging and longevity.
• Societal factors like healthcare access, education, and antigen exposure patterns vary between sexes.

Purpose of the Study:

• To elucidate the interplay between biological sex and gender in immune aging.
• To understand divergent trajectories in immune aging and longevity between males and females.
• To provide a comprehensive view of factors influencing immune responses and health outcomes.

Main Methods:

• Review of existing literature on biological and social factors affecting immune aging.
• Analysis of how gender roles and societal structures impact health behaviors and outcomes.
• Examination of data on sex differences in immune responses, infection susceptibility, and longevity.

Main Results:

• Gender can accelerate immune aging or promote longevity.
• Social and behavioral factors associated with gender contribute to disparities in immune responses.
• Older females demonstrate greater resilience to infections than older males, aligning with longer lifespans.

Conclusions:

• Both biological sex and gender are critical determinants of immune aging and longevity.
• Addressing social and economic disparities is crucial for equitable immune health outcomes.
• Understanding these complex interactions is key to promoting healthy aging across the lifespan.
