Network analysis of a complex disease: the gut microbiota in the inflammatory bowel disease case

no code implementations16 Aug 2022 Mirko Hu, Guido Caldarelli, Tommaso Gili

Inflammatory bowel diseases (IBD) are complex diseases in which the gut microbiota is attacked by the immune system of genetically predisposed subjects when they are exposed to yet unclear environmental factors.
