Stool metaproteomics of children with islet autoimmunity


ABSTRACT: The gastrointestinal ecosystem is a highly complex environment with a profound influence on human health. Inflammation in the gut, linked to an altered gut microbiome has been associated with the development of multiple human conditions including type 1 diabetes (T1D). Viruses infecting the gastrointestinal tract, especially enteroviruses, are also thought to play an important role in T1D pathogenesis possibly via overlapping mechanisms. Here, we apply an integrative approach to combine comprehensive faecal virome, microbiome and metaproteome data sampled before and at the onset of islet autoimmunity in 40 children. We show strong age and antibody related effects across the datasets. Mastadenovirus infection was associated with profound functional changes in the faecal metaproteome. Multiomic factor analysis modelling revealed proteins associated with carbohydrate transport from the genus Faecalibacterium were associated with islet autoimmunity. These findings demonstrate functional remodelling of the gut microbiota accompanies both islet autoimmunity and viral infection.
