From 12 to 14 October, the Barcelona Biomedical Research Park (PRBB) hosted the 11th International Workshop on Technologies for Optogenetics and Neurophotonics (OPTOGEN 2026), co-organised by the Institute for Bioengineering of Catalonia (IBEC) and the Institute of Photonic Sciences (ICFO). Over three days, more than a hundred scientists and technologists from around the world gathered to discuss the latest advances in optical methods and their applications in neuroscience, from new implantable devices to the latest molecular tools to study and control brain activity. <\/strong><\/p>\n\n\n\n

Creada el 2014, la s\u00e8rie OPTOGEN<\/a> s\u2019ha consolidat com una trobada de refer\u00e8ncia sobre tecnologies fot\u00f2niques per a l\u2019estudi del cervell. L\u2019optogen\u00e8tica utilitza prote\u00efnes sensibles a la llum, introdu\u00efdes en grups espec\u00edfics de neurones, per activar-ne o desactivar-ne l\u2019activitat amb polsos de llum. Aix\u00f2 permet comprovar quines c\u00e8l\u00b7lules intervenen en una determinada funci\u00f3 cerebral o en un comportament. L\u2019edici\u00f3 d\u2019enguany, que va comptar amb el suport de la Societat Espanyola de Neuroci\u00e8ncia (SENC)<\/strong>, va comen\u00e7ar nom\u00e9s una setmana despr\u00e9s que el Premi Nobel de Fisiologia o Medicina 2026<\/strong> es conced\u00eds a Karl Deisseroth, Peter Hegemann i Georg Nagel pels seus descobriments sobre els canals i\u00f2nics activats per la llum i l\u2019optogen\u00e8tica<\/em>. <\/p>\n\n\n\n

Cinc confer\u00e8ncies plen\u00e0ries<\/strong><\/h4>\n\n\n\n

Les confer\u00e8ncies plen\u00e0ries van mostrar el ventall de preguntes que les eines basades en la llum permeten abordar avui dia.<\/p>\n\n\n\n

Michael H\u00e4usser<\/strong> (Universitat de Hong Kong i University College London) va presentar enfocaments totalment \u00f2ptics que combinen la microsc\u00f2pia de dos fotons amb l\u2019optogen\u00e8tica de dos fotons. Aquestes t\u00e8cniques permeten dirigir-se a grups concrets de neurones en funci\u00f3 de la seva activitat i influir en el funcionament dels circuits cerebrals, cosa que ajuda a entendre com els patrons d\u2019activitat neuronal modelen el comportament. <\/p>\n\n\n\n

Alexander Gottschalk<\/strong> (Universitat Goethe de Frankfurt), que va treballar al costat d\u2019investigadors implicats en els primers desenvolupaments de l\u2019optogen\u00e8tica, va oferir una perspectiva hist\u00f2rica del camp. A continuaci\u00f3, va explicar com el seu laboratori utilitza eines optogen\u00e8tiques en el nematode Caenorhabditis elegan<\/em>s per estudiar la transmissi\u00f3 sin\u00e0ptica i petits circuits neuronals. El seu equip est\u00e0 desenvolupant eines controlades per llum per bloquejar passos concrets del cicle d\u2019alliberament i reciclatge de neurotransmissors, cosa que ajuda a entendre la cronologia de la comunicaci\u00f3 entre neurones.
Linda Greensmith (UCL Queen Square Institute of Neurology) va presentar una estrat\u00e8gia de ter\u00e0pia cel\u00b7lular per a l\u2019esclerosi lateral amiotr\u00f2fica (ELA). En aquest enfocament, s\u2019empelten al nervi motoneurones derivades de c\u00e8l\u00b7lules mare i modificades per respondre a la llum, que es reconnecten amb els m\u00fasculs paralitzats. En models de ratol\u00ed, incl\u00f2s un model agressiu d\u2019ELA, estimular amb llum les neurones empeltades va fer que els m\u00fasculs reinnervats es contraguessin i va ajudar a prevenir l\u2019atr\u00f2fia de les seves fibres. <\/p>\n\n\n\n

Michael Lin (Universitat Stanford) va presentar els darrers indicadors de voltatge de la fam\u00edlia ASAP desenvolupats al seu laboratori. Es tracta de prote\u00efnes fluorescents codificades gen\u00e8ticament que registren l\u2019activitat el\u00e8ctrica de les neurones a una velocitat de mil\u00b7lisegons, cosa que permet observar en temps real com funcionen els circuits cerebrals. <\/p>\n\n\n\n

Kay Tye<\/strong> (Institut Salk i Institut M\u00e8dic Howard Hughes), que va fer l\u2019etapa postdoctoral amb el premi Nobel Karl Deisseroth, va impartir la confer\u00e8ncia de cloenda del congr\u00e9s. Va parlar dels circuits cerebrals que sustenten l\u2019\u201chome\u00f2stasi social\u201d, \u00e9s a dir, com el cervell estableix un nivell preferit de contacte social i el mant\u00e9 estable dins d\u2019un grup. Mitjan\u00e7ant diferents enfocaments, des de l\u2019optogen\u00e8tica fins a l\u2019electrofisiologia i la imatge, el seu laboratori investiga com s\u2019interconnecten aquests circuits i com diferents mecanismes neuronals actuen conjuntament per modular el comportament. <\/p>\n\n\n\n

De les eines moleculars a les empreses emergents<\/strong><\/h4>\n\n\n\n
\n

Una de les principals raons per les quals encara no entenem del tot com funciona el cervell \u00e9s que ens falten eines per estudiar-lo amb prou detall. L\u2019optogen\u00e8tica i altres m\u00e8todes basats en la llum ens estan ajudant a superar aquestes limitacions, per\u00f2 el progr\u00e9s dep\u00e8n de desenvolupar noves eines i de reunir diferents comunitats cient\u00edfiques. <\/em><\/p>\n\n\n\n

El programa tamb\u00e9 va incloure dotze pon\u00e8ncies convidades, vuit comunicacions orals seleccionades i nou flash talks. Els temes van anar des de fonts de llum org\u00e0niques flexibles per a l\u2019optogen\u00e8tica i microscopis en miniatura muntats al cap d\u2019animals que es mouen lliurement, fins a eines activades per llum vermella i infraroja propera, la fotofarmacologia i l\u2019obtenci\u00f3 d\u2019imatges de circuits cerebrals en formaci\u00f3 en embrions i cries acabades de n\u00e9ixer de ratol\u00ed. Dues sessions de p\u00f2sters i espais diaris de meet-the-speaker van permetre comentar els treballs directament amb les persones ponents. Una taula rodona, \u201cDel laboratori a l\u2019empresa emergent\u201d, va abordar com les tecnologies desenvolupades als laboratoris de recerca poden arribar al mercat. <\/em><\/em><\/p>\n\n\n\n

\u201cCelebrar l\u2019OPTOGEN a Barcelona nom\u00e9s una setmana despr\u00e9s que el Premi Nobel reconegu\u00e9s l\u2019optogen\u00e8tica ha estat una feli\u00e7 coincid\u00e8ncia, per\u00f2 el veritable valor de la trobada \u00e9s la diversitat de perfils reunits: especialistes en f\u00edsica, enginyeria, qu\u00edmica i neuroci\u00e8ncia que poques vegades comparteixen programa\u201d<\/em>, va afirmar Nicol\u00f2 Accanto<\/strong>, l\u00edder del grup Nonlinear Photonics for Neuroscienc<\/a>e de l\u2019IBEC i membre del comit\u00e8 organitzador. \u201cUna de les principals raons per les quals encara no entenem del tot com funciona el cervell \u00e9s que ens falten eines per estudiar-lo amb prou detall.

El comit\u00e8 organitzador tamb\u00e9 el van formar Galyna Malieiev<\/strong>a i Silvia Pittol<\/strong>o (IBEC) i Michael Krie<\/strong>g (ICFO). Per part de l\u2019IBEC, els l\u00edders de grup Pau Gorostiza<\/strong>, Jos\u00e9 Antonio del R\u00edo<\/strong> i Zaida \u00c1lvarez<\/strong> van formar part del comit\u00e8 cient\u00edfic, juntament amb personal investigador de la Universitat de Barcelona i del Centre de Neuroci\u00e8ncies Cajal. <\/p>\n\n\n\n

Tres premis per recon\u00e8ixer les contribucions m\u00e9s destacades<\/strong><\/h4>\n\n\n\n

El congr\u00e9s es va cloure el dimecres 14 d\u2019octubre amb el lliurament de tres premis. Els premis al millor p\u00f2ster van ser per a Karolina Zimkowsk<\/strong>a, de l\u2019IBEC, i Federica Antonelli<\/strong>, de l\u2019Istituto Italiano di Tecnologia, i el premi a la millor flash talk, per a Shu Xie<\/strong>, de la Universitat de Pequ\u00edn. <\/p>\n\n\n\n

Amb l\u2019organitzaci\u00f3 de l\u2019OPTOGEN 2026, l\u2019IBEC refor\u00e7a el seu paper en la recerca en neurotecnologia a Barcelona i el seu comprom\u00eds de connectar la comunitat cient\u00edfica local amb grups internacionals de refer\u00e8ncia que treballen a la intersecci\u00f3 entre la llum, l\u2019enginyeria i la neuroci\u00e8ncia.<\/p>\n\n\n\n

les seves aplicacions en neuroci\u00e8ncia, des de nous dispositius implantables fins a les eines moleculars m\u00e9s recents per estudiar i controlar l\u2019activitat cerebral.","og_url":"https:\/\/ibecbarcelona.eu\/ca\/optogen-2026-reuneix-a-barcelona-mes-de-100-especialistes-en-optogenetica-i-neurofotonica\/","og_site_name":"Institute for Bioengineering of
