... for a diuretic hormone, DH 44 . Here, we report that the other CRF receptor subfamily member, encoded by CG12370 , is also a receptor for the DH 44 neuropeptide. The lines of evidence to support this identification include increases in cAMP levels due to CG12370 receptor activation and the recruitment of β...

...Geoffrey M. Coast SUMMARY The pioneering work of Simon Maddrell established that the rapid postprandial diuresis of the haematophagous insect Rhodnius prolixus is controlled by a diuretic hormone and demonstrated the role of the Malpighian tubules in meeting the volumic, osmotic and ionic...

..., and muscle contractions of the crop, hindgut and dorsal vessel, which facilitate mixing of the blood-meal, mixing of the haemolymph,as well as the expulsion of waste. One of the neurohormones that might play a role in this rapid diuresis belongs to the calcitonin-like diuretic hormone(DH 31 ) family...

...Erik C. Johnson; Laura M. Bohn; Paul H. Taghert SUMMARY Diuretic hormone 44 (DH) is a bioactive neuropeptide that mediates osmotic balance in a wide variety of insects through increases in cAMP. It is structurally similar to mammalian corticotrophin releasing factor (CRF)peptides. In the moth...
