Recently, it has been suggested that senescent cells could play a central role in pathogenesis by exacerbating the pro-­ inflammatory immune response against SARS-­CoV-­2. Therefore, the selective clearance of senescent cells by senolytic drugs may be useful as a therapy to ameliorate the symptoms of COVID-­19 in some cases. Using the established COVID-­19 murine model K18-­hACE2, we demonstrated that a combination of the senolytics dasatinib and quercetin (D/Q) significantly reduced SARS-­CoV-­2-­related mortality, delayed its onset, and reduced the number of other clinical symptoms. The increase in senescent markers that we detected in the lungs in response to SARS-­CoV-­2 may be related to the post-­COVID-­19 sequelae described to date. These results place senescent cells as central targets for the treatment of COVID-­19, and make D/Q a new and promising therapeutic tool.
