Full textThis work presents a detailed morphofunctional study of the digestive system of Phibalosoma phyllinum (Phasmida, Phasmatidae). From an anatomical point of view, the digestive system of this insect is formed by a foregut, a midgut and a hindgut. The foregut is composed by the buccal cavity (where the salivary gland\'s duct open), a pharynx and an aesophagus that ends in the proventriculus. The midgut consists of a tubular ventriculus and it can be divided in three regions: the anterior ventriculus (AV), the middle ventriculus (MV), and the posterior ventriculus (PV) which can be further subdivided in its proximal (PVI), and distal (PVII) sub-regions. The presence of a complex system of ventricular appendices was observed in the PVI sub-region, which are formed by protuberances, in the external ventricular surface, and by blind-ended canaliculi, which are connected to the protuberances. The hindgut is divided into an ileum and a rectum that ends in the anus. Seen by light microscopy, the foregut is made up by a simple epithelium, which is composed of squamous cells and covered by a cuticle layer. Through the whole foregut the cuticle forms spines. The proventriculus is formed by a simple muscular valve that separates the foregut from the midgut. The midgut itself is formed by a simple epithelium, which is made up of three different cell types: columnar cells (enterocytes), which are the main site of enzyme production and secretion, and nutrient absorption, the regenerative cells, which are clustered in nidi at the basal portion of the epithelium, and the endocrine cells. The ventricular appendices, in turn, are formed by a simple epithelium that is continuous with the ventricular epithelium. Cells from the protuberances are large showing a round shape, while canalicular cells are short, and very similar to the ones presented in the Malpighian tubules. In the transition between the midgut and the hindgut, several Malpighian tubes branch off. The hindgut is formed by a simple epithelium, lined by cuticle. The ventricular lumen is covered by a tubular structure called peritrophic membrane whose presence was confirmed by fluorescence microscopy, using chitin-binding lectin WGA (wheat germ agglutinin) coupled with FITC (fluorescein isothiocyanate). In order to identify specific ventricular regions where water absorption and secretion through the epithelium take place, physiological experiments, using amaranth dye solution were performed. This solution was either orally administered, or injected in the hemolinph of both fed and starved insects. These experiments revealed that, both in fed and starved animals, the AV is the main site of water absorption, whereas the Malpighian tubules are the main sites of water secretion into the ventricular lumen. Ultrastructural analysis showed that enterocytes present an apical surface modified into well-developed microvilli. In their lateral surface, the adjacent plasma membranes are linked by desmosomes and smooth septate junctions. The basal plasma membrane shows several infoldings, forming a labyrinth of channels with associated mitochondria. In the AV and MV, these infoldings present a limited number of openings to the basal lamina, which indicates a greater water absorption potential of these regions from the gut lumen. In the PV cells, the number of openings is greater, indicating that these regions may be involved in water secretion (although occurring in levels that are undetectable through dye experiments). Regenerative cells nidi, in turn, can be observed in the basal portion of the epithelium throughout the midgut. This cell type shows characteristics of undifferentiated cells, such as large nuclei and few organelles. Endocrine cells are confined to the basal portion of the epithelium. Both the ventricular canaliculi and the Malpighian tubules are made up by cuboidal cells with modified apical microvilli bearing mitochondria in their interior, and basal plasma membrane forming a labirinth with many well developed infolds and openings to the basal lamina, as well as many associated mitochondria. An intense secretory activity was observed along the entire midgut. Large amounts of rough endoplasmic reticulum, well developed Golgi areas were observed in the enterocytes. In the AV and MV a large number of secretory vesicles could be observed concentrated in the apical portion of the cells, and their contents are probably eliminated by a merocrine mechanism. Along the PV, secretory vesicles are apparently absent but microvilli display dilated tips frequently showing small vesicles in their interior. This observation may indicate the occurrence of a microapocrine secretory mechanism in this ventricular region. The enzymes amylase and trypsin were immunolocalized in the cells from the AV and MV. In these regions, the two enzymes were detected in Golgi areas, secretory vesicles and in the the ventricular lumen, between the microvilli. Thus, both enzymes seem to be produced and eliminated through the same secretory pathway. Luminal pH measurements revealed a great variation of the pH along the intestine of this species. While in its anterior region the pH is acid (5,3 in the foregut and 5,6 in the AV), it becomes gradually alkaline towards the posterior regions (6,3 in the anterior MV, 8,0 in the posterior MV, 9,1 in the PVI and 8,5 in the PVII); in the hindgut the pH is neutral (7,3). The effect of the pH on amylase and trypsin activities was also measured. It was determined that trypsin\'s optimal pH was 9,0, and amylase\'s optimal pH was 5,0. Biochemical assays of digestive enzymes revealed the presence of amylase and trypsin in the luminal contents, mainly in the foregut and AV. In spite of that, it is possible that trypsin\'s activity is greater in the MV and PV, where the alkaline luminal pH matches the optimal pH for this enzyme. Chymotrypsin is also present in the lumen of the foregut and AV, but, unlike amylase and trypsin, its major activity is found in the AV. Aminopeptidase is found in the ventricular epithelium, mainly in the MV and PV, and maltase is detected associated with the microvillar glicocalix in the AV and PV regions. The hindgut showed low levels of digestive enzyme excretion, both in fed and starved animals, suggesting that these enzymes are recovered during the digestive process. Thus, these results point to the occurrence of an endo-ectoperitrophic circulation of digestive enzymes in both fed and starved animals, in which the AV is the main absorption site of water and the Malpighian tubules, the main secretion site. Initial carbohydrates digestion should occur in the foregut and in the AV, in the endoperitrophic space, whereas its final digestion should take place in the epithelial surface. Protein digestion should take place in the MV and in the PV; initial digestion should occur in the luminal endoperitrophic space, whereas final digestion takes place in the epithelial surface of these regions. Carbonic anhydrase assays revealed a high activity of this enzyme in the ventricular appendices. This fact, along with the morphological similarity between ventricular canaliculi and Malpighian tubules suggest that the canaliculi and the Malpighian tubules are homologous structures. Along the evolutionary process, the canaliculi probably acquired the capability to promote the alkalization of the PV lumen (mainly in the PVI region) thus affecting the digestive process

Full textThe Aedes aegypti borne diseases yellow fever, dengue fever, chinkungunya and zica are important public healthy problems. The digestion and absorption of nutrients are performed in the digestive system, which is also an external environment interface that allows the infection by pathogenic microorganisms. The presence of two digestive lipases were identified by qPCR, L-Aa7051 in the larval phase and L-Aa7055 in the adult female. The lipase sequences were grouped in the neutral family, and exhibit alterations in residues involved in specificity, lid domain and β9 loop. The recombinant L-Aa7055 was expressed in the insoluble fraction, and show activity after a renaturation process. We notice that the expression levels of L-Aa7055 are reduced by 30% in the Plasmodium gallinaceum infection and were not affected by serotype 2 dengue virus (DENV2). The lipid digestion is important in the larval phase, with higher transcript levels. New studies will be necessary to the complete understanding of lipase contribution in the infectious process.
