Age-Independent Immunosenescence: An Antigen-Activated, Sexually Dimorphic Program Predicts Inflammation of Aging and HIV-1 Susceptibility

Abstract

In epidemiologic, immunologic, and genetic analyses of 16,217 people, 279 non-human primates, and 334 mice, we identified age-independent immunosenescence (AIIS), a process concurrent with but distinct from age-dependent immunosenescence (ADIS). AIIS is the consequence of an evolutionarily conserved response to antigenic stimulation characterized by unrestrained expansion of CD8+ relative to CD4+ T-cells. At any age, AIIS correlates with lower immunologic integrity, and its immunologic hallmarks (e.g., CD28CD8+ T-cells) have been misattributed to ADIS.
