.... pHCl-2 is expressed in the Malpighian tubules, which are non-innervated renal-type secretory tissues. We demonstrate that pHCl-2 is localized to the apical membrane of the epithelial principal cells of the tubules and that loss of pHCl-2 reduces urine production during diuresis. Our data implicate pHCl...

... by diuresis and stored until it is digested. While serotonin is known to be a diuretic hormone in R. prolixus , a peptidergic factor(s) was also known to play a role in diuresis. In the present study we employed molecular techniques and mass spectrometry to determine the sequence of a native CRF-like peptide...

...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...

... regulating post-prandial diuresis. Allatotropin induced an increase in frequency and intensity of peristaltic contractions at the level of the HG. The release of the HG content in MTs–HG in vitro preparations undergoing an osmotic shock occurred at different times, depending on the number of MTs present...

... the flight pay load upon eclosion from the aquatic habitat. The non-selective NaCl and KCl diuresis stems from the increase in septate junctional Cl - conductance activated by leucokinin using Ca 2+ as second messenger. Fundamental to diuretic mechanisms are powerful epithelial transport mechanisms...

...V. A. Te Brugge; S. M. Miksys; G. M. Coast; D. A. Schooley; I. Orchard ABSTRACT The blood-feeding bug Rhodnius prolixus ingests a large blood meal, and this is followed by a rapid diuresis to eliminate excess water and salt. Previous studies have demonstrated that serotonin and an unidentified...

...Michael C. Quinlan; Nathan J. Tublitz; Michael J. O’Donnell ABSTRACT Rhodnius prolixus eliminates NaCl-rich urine at high rates following its infrequent but massive blood meals. This diuresis involves stimulation of Malpighian tubule fluid secretion by diuretic hormones released in response...

..., but these peptides were not unambiguously identified as F1 and F2. Indeed, even this correlation was not strict: starved animals showed a peak in the titre of AVP-like peptides without a concomitant burst of diuresis ( Picquot and Proux, 1987 ). Even the supposition that F2 acts via adenylyl cyclase activation...
