As organisms age, they accumulate cells that can no longer proliferate. Such cells— termed “senescent”—persist and appear to promote aging by producing and secreting a variety of proteins. Zhu et al. tested whether drugs that inhibit cellular signaling pathways that make senescent cells resistant to stress and cell death could deplete senescent cells in mice. A combination of two drugs that inhibit such pathways selectively killed senescent cells in vitro, improved heart and vascular function in aging mice, and improved symptoms in a mouse model of accelerated aging. Although pinpointing the relevant targets of these drugs is difficult, the studies indicate that selectively targeting senescent cells with small molecules may be feasible.
