Immunologia regenerativa: la sfida contro l'invecchiamento | Ermelinda Porpiglia | TEDxCatania
Viviamo più a lungo che mai, ma vivere a lungo non significa necessariamente vivere bene. Con l’età, i nostri tessuti si riparano più lentamente, le funzioni del corpo si riducono e la qualità della vita può peggiorare. La mia ricerca si concentra su un obiettivo ambizioso: migliorare l’healthspan — cioè il numero di anni in cui restiamo in buona salute — tramite la medicina rigenerativa. In particolare, studiamo come rigenerare i tessuti danneggiati sfruttando una risorsa che abbiamo già dentro di noi: il sistema immunitario. Siamo abituati a pensare al sistema immunitario come a un guerriero che ci protegge da virus e batteri. Ma c’è un lato meno conosciuto: quello del sistema immunitario come “alleato della rigenerazione”, che aiuta il nostro corpo a crescere e guarire. Nel mio laboratorio all’ Universita’ di Aarhus vogliamo capire meglio come le cellule immunitarie supportino le cellule staminali, che hanno il compito di rigenerare i tessuti. Ci chiediamo se questo ruolo di “alleato” del sistema immunitario si perde con l’età. E se sì, possiamo riattivarlo? Per trovare nuove risposte, utilizziamo tecnologie all’avanguardia che ci permettono di osservare, una cellula alla volta, le interazioni tra le cellule staminali e le cellule del sistema immunitario all’interno dei tessuti. Il nostro obiettivo è di studiare nel dettaglio le “nicchie rigenerative”, cioè i micro-ambienti specializzati dove le cellule staminali lavorano insieme alle cellule immunitarie per riparare il corpo. E vogliamo capire se, invecchiando, queste nicchie si deteriorano. Questa ricerca puo’ aiutarci a sviluppare nuove strategie per potenziare la capacità del corpo di guarire, anche in età avanzata. In altre parole: stimolare il nostro sistema immunitario per vivere non solo più a lungo, ma meglio. La Dott.ssa Ermelinda Porpiglia è Professore Associato all’Università di Aarhus, in Danimarca, dove guida un laboratorio che studia come l’invecchiamento influenzi la rigenerazione muscolare. Durante il suo post-doc alla Stanford University ha introdotto l’uso della citometria di massa a singola cellula (CyTOF) nello studio del muscolo scheletrico, identificando sottotipi rari di cellule staminali legati all’età. Il suo lavoro impiega tecnologie all’avanguardia per esplorare l’interazione tra cellule staminali e sistema immunitario, con l’obiettivo di sviluppare terapie che migliorino la riparazione muscolare. Laureata a Bologna e con un dottorato negli Stati Uniti, ha pubblicato su riviste di rilievo come Nature Medicine e Cell Stem Cell ed è Direttrice della Danish Society for Women in Science.

- 17:14How tiny particles may explain why we exist | Dr. Lia Merminga | TEDxChicagoFrom questioning the universe's edge as a child in Athens to leading America's premier particle physics laboratory, Dr. Lia Merminga shares her remarkable journey through the world of scientific discovery. She weaves together her uncle's physics legacy, her former role as Fermilab's first women director, and an ambitious international quest to understand existence itself. Dr. Merminga reveals how the Deep Underground Neutrino Experiment (DUNE) unites 1,400 scientists worldwide in the search for fundamental truths about matter and antimatter, showcasing how global collaboration tackles humanity's biggest questions, such as “why do we exist?”, through cutting-edge physics and engineering.#ParticlePhysics #QuantumPhysics #Neutrinos #Fermilab #DUNE #WomeinScience #InternationalScienceDr. Lia Merminga is a Fermi National Accelerator Laboratory Distinguished Scientist, a fellow of the American Physical Society, Crain’s Chicago Business’ Notable Women in STEM, and a graduate of the first cohort of Department of Energy’s (DOE) Oppenheimer Energy Science Leadership Program. She has served on and led numerous international scientific committees. Dr. Merminga was the first female Laboratory Director at Fermilab where she is overseeing the development and execution of the Deep Underground Neutrino Experiment (DUNE), a first-of-its-kind experiment to unlock the mysteries of neutrinos. This program represents the largest international experiment ever built by the DOE on U.S. soil. Ultimately, it will help us get closer to answering the really big questions; such as, why does the universe, and—by extension—humankind exist?This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

- 16:35What if community is built by sharing stories we hide? | Sónia Silva | TEDxPraça Gil EanesWhat if the stories we’ve been taught to repeat are exactly what keep us apart? In this heartfelt talk, communication coach Sónia Silva shows how our most imperfect, personal stories can become the foundation for authentic community, inviting us to belong not by hiding, but by revealing who we truly are. Sónia Silva is a communication coach, trainer, and co-host of Storytelling Lisboa, where a safe space for storytelling is created for. She has worked with companies, entrepreneurs and TEDx speakers, helping them find authenticity in the way they communicate.Sónia has grown up in an environment where social narratives stories shaped how she saw, and was seen by, the world and therefore she believes that imperfect stories are the invisible glue of communitiesm. By sharing them can we rebuild trust, empathy, and belonging. On stage, she brings a voice committed to the human truth behind social and common narratives.

- 15:50Comico ergo sum: spostarsi con le parole | VINCENZO COMUNALE | TEDxAngriIl concetto parte da un puntino rosso, come il naso di un clown, per simboleggiare il potere generativo delle parole. Non sono semplici descrizioni, ma entità capaci di creare nuove realtà e di farci viaggiare tra sogni e concretezza. Vincenzo Comunale, da comico, usa le parole per trasformare l'ansia in rassicurazione, dimostrando come la comicità possa generare riflessioni profonde ed evocare emozioni complesse. Il suo viaggio è un continuo movimento, tramite l'arte e il linguaggio, per esplorare la "Fantopia" e perseguire i sogni, sia propri che altrui. Le parole diventano così strumenti per la scoperta e la realizzazione Born in Naples in 1996, Vincenzo Comunale began studying acting at the age of thirteen and quickly became one of the youngest and most talented comedians in Italy. In 2025, he was included by Forbes Italia in the list of the 100 Under 30 Italians who are changing the world.
