By turning the liver into a short-term factory for key immune signals (DLL1, FLT3L, IL-7), the authors demonstrate that immune ageing is modifiable, not fixed. &amp;nbsp; This elegant work—covered by Heidi Ledford in Nature—opens provocative questions about immune resilience, ageing biology, and the future of mRNA beyond vaccines. 🧠🛡️ &amp;nbsp; 📄 Friedrich MJ et al., Nature 2025 | News &amp;amp; Views: Ledford H. 🔗 doi:10.1038/s41586-025-09873-4 | doi:10.1038/d41586-025-04082-5 Dr. RR Baliga's 'Podkast for the Kurious Doc' http://www.MasterMedFacts.com <iframe title="Libsyn Player" style="border: none" src="//html5-player.libsyn.com/embed/episode/id/40345950/height/300/theme/custom/thumbnail/yes/direction/forward/render-playlist/no/custom-color/88AA3C/" height="300" width="600" scrolling="no" allowfullscreen webkitallowfullscreen mozallowfullscreen oallowfullscreen msallowfullscreen></iframe> https://assets.libsyn.com/secure/content/199339410
