Oriol Juanola is a PhD. student of the Hepatic and Intestinal Immunobiology Group at Miguel Hernández University (Alicante, Spain). The group is interested in molecular and cellular aspects around the immune system that are responsible for the surveillance, response and regulation of homeostasis with our gut microbiota in the so-called "gut-liver axis", a central element in different metabolic pathologies within the scope of the gastroenterology and hepatology. The translation of these aspects, addressed from different methodological perspectives, to the clinical field is also relevant for the Group in order to improve the diagnosis, treatment and/or prognosis of these diseases. Rubén Francés is professor of Immunology and Head of the Hepatic and Intestinal Immunobiology Group at Miguel Hernández University and the Biomedical Research Networking Center in Hepatic and Digestive Diseases (CIBEREHD).
