Costa Clélia Ferreira Multidisciplinaria (Ciencias Naturales y Exactas) ion transport water transport nutrient absorption microvillar membranes perimicrovillar membranes Plasma membranes from insect midgut cells are separated into apical and basolateral domains. The apicaldomain is usually modified into microvilli with a molecular structure similar to other animals. Nevertheless,the microvillar structure should differ in some insects to permit the traffic inside them of secretory vesicles thatmay budd laterally or pinch-off from the tips of microvilli. Other microvillar modifications are associated withproton-pumping or with the interplay with an ensheathing lipid membrane (the perimicrovilllar membrane)observed in the midgut cells of hemipterans (aphids and bugs). The perimicrovillar membranes are thoughtto be involved in amino acid absorption from diluted diets. The microvillar and perimicrovillar membraneshave densities (and protein content) that depend on the insect taxon. The role played by the microvillar andperimicrovillar proteins in insect midgut physiology is reviewed here trying to provide a coherent picture ofdata and highlighting further research areas. 2006 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32778207 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.2 Vol.78 |
