6. Human copper ion transfer : from metal chaperone to target transporter domain
Sammanfattning : Many processes in living systems occur through transient interactions among proteins. Those interactions are often weak and are driven by small changes in free energy. LÄS MER
7. Expression and regulation of water channels and ion transporters : ontogenic aspects
Sammanfattning : The content and distribution of body water changes dramatically during the perinatal period and in infancy. Transport of water across the cell membrane occurs via diffusion and via specific water channels. Transport via water channels is fast and may be hormonally regulated. LÄS MER
8. Ion transport in exocrine glands with reference to cystic fibrosis
Sammanfattning : Aspects of ion transport in rat submandibular gland acinar cells at the subcellular level, and the regulation of chloride secretion and calcium mobilization in cultured pig tracheal gland acinar cells were studied with reference to the disease cystic fibrosis.In adult rat submandibular gland acinar cells, both cholinergic and α-adrenergic stimulation induced efflux of K+ and of C1-, but the response was generally less with α-adrenergic stimulation.

9. Determining the effects of regulatory parameters on the structural dynamics of P-type ATPase membrane transporters
Sammanfattning : Proteins are macromolecular machines with roles in all cellular activities and structures. The functional properties of each protein is the result of its combination of 3D-structure and inherent dynamics, and a wealth of structural and dynamic mechanisms have evolved to regulate protein activity.

10. Colonic barrier function in ulcerative colitis - Interactions between ion and mucus secretion
Sammanfattning : Anion and mucus secretions have traditionally been looked upon as two separate parts of the epithelial defense system. The importance of anion secretion has been attributed to its role in creating the driving force for fluid secretion that flushes the epithelium from bacteria, while mucus secretion ensures protection via the mucus layer that forms a physical barrier between the bacteria and the epithelium.
