At the first EV4 – Extracellular Vesicles in Visegrad Collaboration conference (21–22 October 2026, Budapest), our team was represented by Doctor Barbora Tamášová and Doctor Kristína Truchanová – our former PhD student, currently an active collaborator and Vice President of the Slovak Society for Extracellular Vesicles. In addition to chairing two sessions, they also presented joint research focused on the characterization of DNA on extracellular vesicles in juvenile idiopathic arthritis.
