Ion transport processes of crustacean epithelial cells.
Epithelial cells of the gut, antennal glands, integument, and gills of crustaceans regulate the movements of ions into and across these structures and thereby influence the concentrations of ions in the hemolymph. Specific transport proteins serving cations and anions are found on apical and basolateral cell membranes of epithelia in these tissues. In recent years, a considerable research effor...
متن کاملEpithelial Electrolyte Transport Physiology and the Gasotransmitter Hydrogen Sulfide
Hydrogen sulfide (H2S) is a well-known environmental chemical threat with an unpleasant smell of rotten eggs. Aside from the established toxic effects of high-dose H2S, research over the past decade revealed that cells endogenously produce small amounts of H2S with physiological functions. H2S has therefore been classified as a "gasotransmitter." A major challenge for cells and tissues is the m...
متن کاملReview Cytokine regulation of epithelial permeability and ion transport
Introduction The intestinal epithelium serves as a dynamic barrier which, in the course of its normal function, maintains regulated uptake of nutrients and water at the same time as excluding potential pathogens. Enteropathies, including inflammatory bowel disease (IBD) result in, or perhaps even from, perturbed epithelial function. Despite the idiopathic nature of IBD, it is apparent that much...

متن کاملAlveolar epithelial ion and fluid transport: recent progress.
Studies of epithelial ion and fluid transport across the distal pulmonary epithelia have provided important new concepts regarding the resolution of pulmonary edema, specifically the removal of edema from the distal airspaces of the lung. Overall, there is convincing evidence that vectorial ion transport across the alveolar and distal airway epithelia is the primary determinant of alveolar flui...
