Exploring the sialome of the blood-sucking bug Rhodnius prolixus.
Rhodnius prolixus is a Hemiptera that feeds exclusively on vertebrate blood in all life stages. Its salivary glands produce potent pharmacological substances that counteract host hemostasis, including anti-clotting, anti-platelet, and vasodilatory substances. To obtain a further insight into the salivary biochemical and pharmacological complexity of this insect, a cDNA library was randomly sequ...
متن کاملExcretion in the Blood-sucking Bug, Rhodnius Prolixus Stal. 3. the Control of the Release of the Diuretic Hormone.
It seemed reasonable to suppose that the release of the hormone was stimulated nervously or Immorally or both. The possibility of nervous control was examined first. Various of the nervous connexions to the ganglionic mass (Fig. 1) were cut, the insects were fed and the amount of urine subsequently produced was measured as described elsewhere (Maddrell, 1964). After diuresis the insects were di...
متن کاملExcretion in the Blood-sucking Bug, Rhodnius Prolixus Stal. Ii. the Normal Course of Diuresis and the Effect of Temperature.
It has recently been shown that the diuresis of fed 5th-stage larvae of Rhodnius is brought about by a hormone that appears in the haemolymph (Maddrell, 1962, 1963). This diuretic hormone is released from the fused ganglionic mass in the mesothorax, probably from its posterior neurosecretory cells. This paper examines some of the features of this diuresis in the light of this discovery and incl...
متن کاملAn unusual myosuppressin from the blood-feeding bug Rhodnius prolixus.
The myosuppressin (MS) gene was cloned from a central nervous system (CNS) cDNA library of the hematophagous insect Rhodnius prolixus and is predicted to contain two introns and three exons. The mRNA transcribed from the myosuppressin gene encodes an 88 amino acid prepropeptide, which results in a mature decapeptide after post-translational modification. When compared with the myosuppressins is...
متن کاملNitric oxide loading of the salivary nitric-oxide-carrying hemoproteins (nitrophorins) in the blood-sucking bug Rhodnius prolixus.
The salivary glands of the blood-sucking bug Rhodnius prolixus are formed by a single layer of binucleated epithelial cells surrounded by a double layer of transversely oriented smooth muscle cells. The epithelial cells are rich in rough endoplasmic reticulum and mitochondria and have abundant microvillar projections towards the gland lumen. This cell layer surrounds a relatively large cavity w...
