Ion channels in the human red blood cell membrane: their further investigation and physiological relevanceLars Kaestner
Biophysics Section, Institute of Biology, Humboldt University Berlin, Invalidenstr. 42, 10115 Berlin, Germany
Bioelectrochemistry 55:71-4. 2002..We give also evidence that another channel in the RBC membrane, so far assumed to be a small conductance anion channel, is more likely to be a proton or a hydroxyl ion channel...- The diversity of current research in the red cell fieldIngolf Bernhardt

Cell Physiol Biochem 22:269-78. 2008..In addition, aldosterone leads to an acidification of the intracellular medium after an initial alkalisation due to an effect on the Na(+)/H(+) exchanger... - Differential effect of HOE642 on two separate monovalent cation transporters in the human red cell membraneIngolf Bernhardt
Laboratory of Biophysics, Saarland University, Saarbruecken, Germany
Cell Physiol Biochem 20:601-6. 2007..The findings are discussed in the context of red blood cell apoptosis (eryptosis) and disease... - Application of digital holographic microscopy to investigate the sedimentation of intact red blood cells and their interaction with artificial surfacesIngolf Bernhardt
Laboratory of Biophysics, Faculty of Natural and Technical Sciences III, Saarland University, Saarbruecken, Germany
Bioelectrochemistry 73:92-6. 2008..With the applied technique we were able to detect and analyse fast shape changes of red blood cells... - Calcium imaging of individual erythrocytes: problems and approachesLars Kaestner
Institute for Molecular Cell Biology, Faculty of Medicine, Saarland University, 66421 Homburg Saar, Germany
Cell Calcium 39:13-9. 2006..Our results emphasize that in erythrocytes measurements of intracellular calcium are reliably possible with Fluo-4 and that other indicators, especially those requiring UV-excitation, appear less favourable... - Regulation of phosphatidylserine exposure in red blood cellsDuc Bach Nguyen
Faculty of Natural and Technical Sciences III, Saarland University, Saarbruecken, Germany
Cell Physiol Biochem 28:847-56. 2011..In sheep RBCs, only the latter mechanism occurs suggesting absence of scramblase activity... - Changes in the intracellular Ca2+ content in human red blood cells in the presence of glycerolOlga A Kofanova
Laboratory of Biophysics, Faculty of Natural and Technical Sciences III, University of the Saarland, Saarbruecken, Germany
Bioelectrochemistry 73:151-4. 2008..Freeze-thawing and deglycerolization of RBCs resulted in a more pronounced increase in the Ca2+ content. Also in this case, the Ca2+ pump seemed to play a major role... - Stimulation of human red blood cells leads to Ca2+-mediated intercellular adhesionPatrick Steffen
Experimental Physics Department, Saarland University, 66123 Saarbruecken, Germany
Cell Calcium 50:54-61. 2011.... - Prostaglandin E2 activates channel-mediated calcium entry in human erythrocytes: an indication for a blood clot formation supporting processLars Kaestner
Institute for Molecular Cell Biology, Faculty of Medicine, Building 61, Saarland University, 66421 Homburg Saar, Germany
Thromb Haemost 92:1269-72. 2004..Therefore, we conclude that the PGE(2) responses of red blood cells described here reveal a direct and active participation of erythrocytes in blood clot formation... - Inhibitors of the K+(Na+)/H+ exchanger of human red blood cellsErwin Weiss
Laboratory of Biophysics, Faculty of Natural and Technical Sciences III, University of the Saarland, P O Box 151150, , Germany
Bioelectrochemistry 62:135-40. 2004..It remains still unclear to what extent the K+(Na+)/H+ exchanger is inhibited by the different substances used. However, the ground state membrane permeability for K+ is much smaller than assumed so far... - Conformational change of membrane proteins leads to shape changes of red blood cellsThomas Betz
Laboratory of Biophysics, Saarland University, P O Box 151150, 66041 Saarbrucken, Germany
Bioelectrochemistry 70:122-6. 2007..Using the human red blood cell (RBC) as a model, we have demonstrated an important correlation between the conformation of membrane proteins measured from the external face of the cell and the cell shape... - Effect of the ionic strength and prostaglandin E2 on the free Ca2+ concentration and the Ca2+ influx in human red blood cellsYuliya V Kucherenko
Institute for Problems of Cryobiology and Cryomedicine of the National Academy of Sciences of Ukraine, Pereyaslavskaya str. 23, 61015 Kharkov, Ukraine
Bioelectrochemistry 62:127-33. 2004..The present findings suggest that stimulation of the Ca(2+)-activated K+ channel by PGE2, reported in [J. Biol. Chem. 271 (1996) 18651], cannot be mediated via increased [Ca2+]i... - Enhanced suicidal death of erythrocytes from gene-targeted mice lacking the Cl-/HCO(3)(-) exchanger AE1Ahmad Akel
Department of Physiology, University of Tubingen, Tubingen, Germany
Am J Physiol Cell Physiol 292:C1759-67. 2007..In conclusion, lack of AE1 is associated with enhanced Ca(2+) entry and subsequent scrambling of cell membrane phospholipids...
