Signal Transduction: A Different Kind of Toll Is in the BAG

A recent study identifies a role for a Toll pathway with likely non-canonical features in the developmental specification of BAG neurons in Caenorhabditis elegans. These neurons function to sense carbon dioxide, which is shown to facilitate avoidance of pathogenic bacteria.
