A2 Química Orgánica K1 Dapansutrile K1 Lonafarnib K1 NLRP3 K1 progeria AB The role of the inflammasomes in aging and progeroid syndromes remain understud-ied. Recently, MCC950, a NLRP3 inhibitor, was used in Zmpste24−/− mice to amelio-rate the phenotypes. However, the safety of MCC950 was questioned due to livertoxicity observed in humans. Nevertheless, inhibition of the inflammasomes wouldbe a beneficial therapy for progeria. Here, we show that OLT1177 (dapansutrile),other NLRP3 inhibitor, improved cellular and animal phenotypes using progeroid fi-broblasts and a Lmna G609G/G609G mouse model. In both cases dapansutrile reducedprogerin accumulation, NLRP3-inflammasome activation and secretory phenotype ofsenescence, extended the lifespan of progeroid animals, preserved bodyweight, andreduced kyphosis, inflammation, and senescence. Interestingly, dapansutrile furtherimproved the effect of lonafarnib, the only FDA-approved drug for the progeria. Thecombination of both drugs reduced the inflammation and senescence, extended sur-vival and ameliorated various progeroid defects both in vitro and in vivo, comparedwith treatment using lonafarnib alone. These findings and the safety of dapansutriledemonstrated in several clinical trials proposes it as a possible co-adjuvant treatmentwith lonafarnid in HGPS PB Wiley SN 1474-9726 YR 2024 FD 2024-09-12 LK http://hdl.handle.net/10498/35694 UL http://hdl.handle.net/10498/35694 LA eng DS Repositorio Institucional de la Universidad de Cádiz RD 07-nov-2026
