Identification of intestinal mediators of Caenorhabditis elegans DBL-1/BMP immune signaling shaping gut microbiome composition

Compared to the roles of diet, environmental availability, or life style in determining gut microbiome composition, that of genetic factors is the least understood and often underestimated. The identification of intestinal mediators acting downstream of DBL-1/BMP signaling to control enteric bacteria, describes a cocktail of effectors with distinct molecular functions, thus offering a glimpse into the genetic logic of microbiome control as well as a list of targets for future exploration of this logic.
