Review synthesizes mechanistic evidence on blood factors that regulate aging, suggesting novel rejuvenation therapies.

Investigate how blood factors influence aging and explore potential rejuvenation strategies.
Utilized multi-omics approaches including plasma proteomics and metabolomics to analyze blood components.
Examined the effects of youthful circulation on tissue maintenance via methodologies like heterochronic parabiosis.
Assessed the impact of specific blood fractions on aging-related processes in animal models.
Circulating proteins and metabolites serve as predictors of aging, healthspan, and disease risk.
Youthful blood components promote regeneration and reverse aging markers in tissues.
Diluting pro-aging factors shows potential in reducing age-related decline, especially in neurodegenerative disease.
