Aims and ScopeWith the exciting title 'Gut-Brain-Axis' we would like to open an interdisciplinary discussion of the newest findings on how gut microbiota signal to the central nervous system and vice versa. We encourage researchers to present their data on the relation between the gut microbiota and neurodegenerative, psychiatric diseases to uncover novel therapeutic strategies. In general, we would like to focus on the communication between the immune sytem and the central nervous system. Furthermore, changes in the immune homeostasis of those cardinal systems will be discussed. In addition, the network of the enteric nervous system will be reviewed.Any other related topics are welcome!Our poster session offers a chance to present projects by young participants.Key topics of the conferenceRole of gut microbiota and intestinal immune system in neuropsychiatric - neurodegenerative diseases and CNS infections / Immune homeostasis and gut microbiota / Intestinal and CNS immune homeostasis / Interaction of central and enteric nervous system
