Here, we characterize peripheral blood mononuclear cells from 172 healthy adults 21~90 years of age using RNA-seq and the weighted gene correlation network analysis (WGCNA). These data have revealed a meaningful of gene expression modules or representative biomarkers for human immune system aging in Aisan and White ancestry. Among them, several gene modules demonstrated a remarkably correlation with human immune aging progress. Besides, further analysis on these ageing related modules show age-related gene expression changes spike is around early-seventies. More importantly, we also focus on how race and ethnicity affect immune aging as race-specific effects on these gene expression changes have clinical applications for diagnosis and interpretation of immunosenescence. Thus, the top hub genes including NUDT7, CLPB, OXNAD1 and MLLT3 are identified from Asian and white aging related modules and further validated in humans PBMC at different ages. Finally, the impact of age and race on immune phenotypes we discuss may provide insights into future studies.Competing Interest StatementThe authors have declared no competing interest. ER -
