Neuronal DAF-16-to-intestinal DAF-16 communication underlies organismal lifespan extension in C. elegans
knockout in neurons and the intestine, respectively. In addition, the systemic regulation of intestinal DAF-16 required the IIS pathway in intestinal and neurons. Collectively, these results highlight the importance of the neuronal DAF-16-to-intestinal DAF-16 communication for organismal lifespan regulation.
