A novel platform for precise senolysis.

The selective eradication of senescent cells using senolytic compounds represents a promising strategy to treat senescence-associated diseases like aging and cancer. However, many senolytics may cause systemic toxicity. Magkouta et al., writing in Nature Aging, introduced mGL392, an advanced senolytic platform utilizing a lipofuscin-binding domain scaffold conjugated with a senolytic drug (e.g., dasatinib). mGL392 effectively eliminates senescent cells in vitro and in vivo, reducing tumor size in melanoma models while minimizing systemic toxicity. Compared to existing senolytics, it offers improved specificity, reducing off-target effects. This innovation presents a safer and more effective approach for treating senescence-related diseases.
