Abstract
Although senolytics such as dasatinib and quercetin (D+Q) show promise in modulating aging, their tissue-specific efficacy and optimal intervention timing remain poorly understood. Given D+Q's potential off-target effects, incomplete senescent cell clearance and associated hematologic side effects, we performed an unbiased multitissue single-cell analysis in aged mice across different aging phenotypes and tissue contexts. Here through integrative transcriptomics, single-cell technologies, histopathology and molecular profiling, we investigated the influence of D+Q treatment on aging-related phenotypes at the tissue and cellular levels. Specifically, D+Q remodeled immunity by enhancing immune cell function and maintaining population stability, alleviated tissue inflammation and improved metabolic profiles. Furthermore, intervention initiated during early aging and prolonged treatment showed a greater tendency to mitigate readouts of aging compared to shorter, late-stage treatment. Our findings reveal that D+Q systematically attenuates several aging hallmarks in a tissue- and cell-type-specific manner, and support the possibility that early-initiated, long-term intervention may amplify efficacy.
