Abstract
Interleukin 12 (IL-12), a central cytokine acting on T and natural killer (NK) cells, directs proliferation of activated T lymphocytes towards a Th1 phenotype. The heterodimeric molecule IL-12p70, equates with IL-12 biological activity, while IL-12p40 may antagonize IL-12 and inhibit cytotoxic T lymphocyte (CTL) generation in vitro. This study characterizes age-related changes in serum total IL-12, IL-12p70 and IL-12p40 relating them with CD3(+), NK and related subsets from subjects, aged 30-96 years. Total IL-12, IL-12p40 and the IL-12p40/IL-12p70 ratio, but not IL-12p70, increased significantly with age (P
