Abstract
Internal organs constantly exchange signals, and can respond with striking anatomical and functional transformations, even in fully developed organisms. We are exploring the mechanisms that drive and sustain such plasticity using the intestine and its neurons as experimental systems. I will present some of our recent work, which has characterised the enteric nervous system of Drosophila, and has explored its physiological plasticity as well as that of the intestine itself. This work has uncovered unexpected sexual dimorphisms, intestinal contributions to reproductive success and metabolic crosstalk between the gut and the brain. Interestingly, this crosstalk appears to be spatially constrained by the three dimensional arrangement of viscera, revealing a previously unrecognised layer of inter-organ signalling regulation. I may also describe our attempts to explore how broadly applicable our findings may be using mammalian systems.
