Senolytics combat COVID-19 in aging
Aging increases vulnerability to respiratory viral infections, including by SARS-CoV-2. Delval et al. established a causal role for age-related pre-existing senescent cells in the severity of COVID-19 symptoms in an aging hamster model. Selective depletion of senescent cells using senolytic agents mitigated the risk of severe COVID-19 symptoms linked to aging.
