Chemical Modification of a Membrane Protein by Hydrophobic and Hydrophilic Labeling Reagents

The major transmembrane protein of the erythrocyte membrane — band 3 — has been chosen as an example of an integral membrane protein. This polypeptide is known to be involved in anion transport and has therefo...

Charge clusters and the orientation of membrane proteins

Although hydrophobic forces probably dominate in determining whether or not a protein will insert into a membrane, recent studies in our laboratory suggest that electrostatic forces may influence the final ori...

Can viral envelope proteins act as or induce proton channels?

The mechanism of the process leading to cell-cell fusion induced by enveloped viruses at a mildly acidic pH is as yet unknown. In this report we demonstrate that the fusion events induced by three viruses of d...

Exposure of Semliki Forest virus-infected baby hamster kidney cells to low pH leads to a proton influx and a rapid depletion of intracellular ATP which in turn prevents cell-cell fusion

The conditions needed to trigger Semliki Forest virus (SFV) induced cell-cell fusion from within (FFWI) of baby hamster kidney (BHK) cells differs from some other cells (e.g., Aedes albopictus cells). In contr...

Dynamic changes in plasma membrane properties of semliki forest virus infected cells related to cell fusion

The mechanism of the processes leading to membrane fusion is as yet unknown. In this report we demonstrate that changes in membrane potential and potassium fluxes correlate with Semliki Forest virus induced ce...

A comparative study of the effect of dextran sulfate on the fusion and the in vitro replication of influenza A and B, Semliki Forest, vesicular stomatitis, rabies, Sendai, and mumps virus

The effect of dextran sulfate on the fusion of a series of enveloped viruses, bearing specifically different fusion proteins, was investigated. The fusion with model- and with biological membranes was monitore...

The fragmentation of incoming Semliki Forest virus nucleocapsids in mosquito (Aedes Albopictus) cells might be coupled to virion uncoating

The fate of Semliki Forest virus (SFV) nucleocapsid, especially the capsid protein (C-protein), was investigated during the early stages of a productive infection in mosquitoAedes albopictus cells. Infection of t...

Cleavage of incoming Semliki Forest virus capsid protein within the endocytotic pathway: a feature common to both invertebrate and mammalian cells

During the initial stages of Semliki Forest virus (SFV) infection in mammalian (baby hamster kidney, BHK) cells, the cleavage of SFV capsid protein could be detected. Analysis of subcellular fractions from SFV...

Combined Calcium and Vitamin D3 Supplementation in Elderly Women: Confirmation of Reversal of Secondary Hyperparathyroidism and Hip Fracture Risk: The Decalyos II Study

Vitamin D insufficiency and low calcium intake contribute to increase parathyroid function and bone fragility in elderly people. Calcium and vitamin D supplements can reverse secondary hyperparathyroidism thus...
