- Maintenance of hindgut reabsorption during cold exposure is a key adaptation for Drosophila cold tolerance
Highlighted Article: A novel assay measuring hindgut ion and fluid reabsorption in Drosophila shows that inter- and intraspecific differences in cold tolerance are linked to maintenance of hindgut osmoregulatory capacity at low temperature.
- Malpighian tubules of Trichoplusia ni: recycling ions via gap junctions and switching between secretion and reabsorption of Na+ and K+ in the distal ileac plexus
Summary: The distal ileac plexus of larval lepidopterans recycles ions using gap junctions, and switches between ion secretion and reabsorption in response to input from the upstream components of the tubule.
- The gastric caecum of larval Aedes aegypti: stimulation of epithelial ion transport by 5-hydroxytryptamine and cAMP
Summary: Transport of H+, Na+ and K+ across the gastric caecum of larval mosquitoes is stimulated by serotonin acting through the intracellular messenger cAMP.
- Biomineralization-related specialization of hemocytes and mantle tissues of the Pacific oyster Crassostrea gigas
Summary: Different subpopulations of oyster hemocytes are specialized for biomineralization or immune functions as revealed by functional differences and gene expression profiles.
