We have had an exceptional 5th CEBC congress in Krakow , in which our Laboratory actively participated both on the scientific front: serving as chairpersons for the plenary lecture, which was delivered by the distinguished clinician-scientist Prof. Gustavo Turecki from McGill University in Montreal, Canada; dr hab. Agata Faron-Górecka, prof. Gustavo Turecki, prof. Marta Dziedzicka-Wasylewska serving as chairpersons of Session1: Blood-brain barrier dysfunction in CNS disoders , during which a lecture was given by Prof. Marta Dziedzicka-Wasylewska (IF PAN), dr hab. Agnieszka Chocyk (IF PAN), and dr hab. Barbara Błasiak (IFJ). we presented three posters during the poster session: Dr Joanna Solich, Dr Magdalena Kolasa, and Ms. Agata Korlatowicz. On the organizational side, dr hab. Agata Faron-Górecka and dr Joanna Solich were responsible for abstracts and the folder. It was a very impressive and enlightening experience!
