The role of the TGF-ß/DBL-1 pathway in shaping the C. elegans gut microbiota

Comparison of gene expression profiles of Caenorhabditis elegans fed a complex microbiota (either a synthetic community or in soil) or a standard Escherichia coli diet. We find that immune and digestion genes are up-regulated in C. elegans that were fed a complex microbiota. Overall design: C. elegans were fed a complex microbiota (either a synthetic community or in soil) or a standard E. coli diet.
