Haem is an iron-containing cofactor required for life. Many cellular processes rely on haem and failure to maintain iron homeostasis results in numerous pathological conditions. A study now identifies a Caenorhabditis elegans inter-organ signalling pathway in which secreted intestinal HRG-7 and neuronally secreted BMP signals coordinate animal haem homeostasis.
