Researchers have discovered that blood signatures of cell type-specific aging can forecast disease risk and resilience, according to a study published in Nature Medicine on June 15, 2026.[1111562][1111564] The study found diverse aging profiles across more than 40 cell types, with links between accelerated aging of specific cell types and increased disease risk.[1111564] Plasma proteomic signatures can be used to evaluate the biological age of individual cell types, revealing potential targets for intervention and prevention strategies.[1111564]
