Proteomics of aging: biomarkers for physiological systems and diseases
Aging is a progressive, multisystem process characterized by declining physiological resilience and increased susceptibility to chronic diseases. Recent advances in high-throughput proteomics have enabled comprehensive mapping of age-related changes across circulating proteins, revealing dynamic and non-linear trajectories that reflect biological rather than chronological aging. This review synthesizes current evidence on proteomic biomarkers across major physiological systems, including the immune, metabolic/endoc …
