37 proteins identified that keep centenarians' bodies biologically younger

Researchers analyzing the SWISS100 cohort have mapped the proteomic signature of centenarians against hospitalized geriatric patients (ages 80–90) and younger healthy adults (ages 30–60), identifying 583 differentially expressed proteins in those who reach 100 years old. The critical finding is a subgroup of 37 proteins that retain a biologically younger profile in centenarians, suggesting aging is neither linear nor inevitable across all molecular systems. These results were validated against independent centenarian proteomics studies, establishing a robust set of aging-associated proteins. Pathway analysis of these 37 proteins mapped to programmed cell death, metabolic enzyme regulation, extracellular matrix stability, immune and inflammatory responses, and neurotrophic signaling—precisely the mechanisms longevity science aims to modulate. For the biohacking-curious reader, the implication is that longevity compression may not be purely genetic luck, but rather the maintenance of specific cellular processes that could potentially be targeted through pharmacological or metabolic intervention.
