On 1–2 November 2024, the annual Biomarkers of Aging conference welcomed academic and industry scientists, and partners from governmental and nongovernmental organizations, to Harvard Medical School in Boston, USA, to discuss new insights into measuring and monitoring human aging, with the aim of clinical translation. In this Meeting Report, we summarize the conference and offer potential future directions for the Biomarkers of Aging Consortium and the longevity science community at large.

AbstractWhile previous studies identified common genetic variants associated with longevity in centenarians, the role of the rare loss-of-function (LOF) mutation burden remains largely unexplored. Here, we investigated the burden of rare LOF mutations in Ashkenazi Jewish individuals from the Longevity Genes Project and LonGenity study cohorts using whole-exome sequencing data. We found that centenarians had a significantly lower burden (11-22%) of LOF mutations compared to controls.

AbstractAging is a major risk factor for neurodegenerative diseases, and coronavirus disease 2019 (COVID-19) is linked to severe neurological manifestations. Senescent cells contribute to brain aging, but the impact of virus-induced senescence on neuropathologies is unknown. Here we show that senescent cells accumulate in aged human brain organoids and that senolytics reduce age-related inflammation and rejuvenate transcriptomic aging clocks.
