Major areas of interest in microbiome research

Gut microbiota-gut-brain axis related to pain, emotional-affective processing and cognitive function Microbial factors (e.g., lipopolysaccharide, peptidoglycan, lipoteichoic acid a.o.) with a role in gut-brain and immune-brain communication Effects of diet-related factors on the microbiota-gut-brain axis Effects of probiotics on the microbiota-gut-brain axis Roles of gut hormones and neuropeptides in the gut microbiota-gut-brain axis
