PURPOSE The neural retina expresses multiple monocarboxylate transporters (MCTs) that are likely to play a key role in the metabolism of the outer retina. Recently, it was reported that targeting of MCT1 and -4 to the plasma membrane requires association with 5A11/basigin (CD147). In the present study, the hypothesis that reduced amplitudes in the(More)
The pH profile, gross structure, ultrastructure and immunolabeling of the mosquito (Aedes aegypti) larval midgut are described as a first step in analyzing the role of plasma membrane H(+ )V-ATPase in the alkalization of the gut, nutrient uptake and ionic regulation. Binding of an antibody to H(+ )V-ATPase subunit E colocalizes with 'portasomes'(More)
PURPOSE 5A11/Basigin has recently been identified as a critical glycoprotein for full maturity and function of the mouse retina. However, the biological function of 5A11/Basigin has yet to be determined. Previous reports indicate the presence of multiple 5A11/Basigin polypeptides within the retina. Therefore, in an effort to determine the function of(More)
The midgut of mosquito larvae maintains a specific lumen alkalinization profile with large longitudinal gradients (pH approximately 3 units*mm(-1)) in which an extremely alkaline (pH approximately 11) anterior midgut lies between near-neutral posterior midgut and gastric cecum (pH 7-8). A plasma membrane H(+) V-ATPase energizes this alkalinization but the(More)
5A11/Basigin is a member of the immunoglobulin gene superfamily which plays an important role in cell-cell interactions in the developing neural retina. These studies were initiated to investigate the distribution of 5A11/Basigin within the mouse retina, as well as the cytoarchitectural and biochemical effects on the retina after the inactivation of the(More)
Glutamine synthetase (GS) has been qualified as a very specific marker of astroglial-type neuroglia in vertebrate neural tissues. In this paper we have begun to examine the possibility that glial localization of GS could be a ubiquitous characteristic of complex nervous systems. To this end we have used immunohistochemistry to localize GS-like(More)
We have previously demonstrated the involvement of carbonic anhydrase (CA) in larval mosquito midgut physiology. In this study, we used Hansson's histochemistry to examine the distribution of the enzyme in the midgut of Aedes aegypti, Aedes albopictus, Culex quinquefasciatus, Culex nigripalpus, Ochlerotatus taeniorhynchus, Anopheles albimanus and Anopheles(More)
BACKGROUND Aquaporin (AQP) water channels are important for water homeostasis in all organisms. Malaria transmission is dependent on Anopheles mosquitoes. Water balance is a major factor influencing mosquito survival, which may indirectly affect pathogen transmission. METHODOLOGY/PRINCIPAL FINDINGS We obtained full-length mRNA sequences for Anopheles(More)
During vertebrate neural retina development, the relationship between mitotic activity in progenitor cells and the acquisition of a mature cell phenotype remains an area of controversy. The Müller glial cell has long been recognized as one of the last cell types of the retina to mature, which occurs under the influence of cell-cell interactions. In this(More)
The immunohistochemical localizations of the enzymes glutamine synthetase, carbonic anhydrase-C, and the intermediate filament protein GFA were examined for potential neuroglial specificity in the retinas of several types of fish. Both glutamine synthetase and carbonic anhydrase-C appear to be characteristic markers for retinal Müller cells. However, the(More)
