Interleukin-2 Induced Changes in Mononuclear Cell Surface Charge

1988
Interleukin-2 (IL-2) is not only the hormone responsible for progression of the T cell cycle, but it is also a potent activator of cytolytic (lymphokine-activated killer, LAK) activity against a wide variety of autologous and allogeneic tumours1. These effects are mediated through specific target cell membrane receptors.

Alterations in surface charge density versus changes in surface charge topography in aging red blood cells

Blut, 1980
The changes in hematological parameters and physicochemical composition of red cells which accompany their aging in vivo and the results of recent experiments in which the peripheral zone of density fractionated erythrocytes were labeled with positively charged colloids or treated with relatively high molecular weight polycations suggest a reordering ...

Non-pn-junction-based solar cells: Charge carrier separation in solar cells with bound surface charges

2014 IEEE 40th Photovoltaic Specialist Conference (PVSC), 2014
Traditional junction-based solar cells have limitations on picking the right materials and processing steps to form a working junction due to, for example, lattice mismatch, doping, and band alignment. In this work, we then demonstrated a new approach to realize the charge carrier separation in solar cells with the bound surface charges on ...

Cell Surface Charge and Cell Division in Escherichia coli after X Irradiation

Radiation Research, 1981
Simultaneous detection of electrophoretic mobility (EPM) and morphology of individual irradiated Escherichia coli cells under the phase microscope revealed a concurrent decrease in EPM and arrest of cell division. EPM decreased with time and reached a minimum 15 min after irradiation with doses ranging from 100 R to 80 kR.

Some effects of positively charged surface groups on cell aggregation

Journal of Cell Science, 1976
ABSTRACT A study was made of the effects of 2,3-dimethylmaleic anhydride (DMA), a reagent removing positive charges, on the aggregation and surface charge of embryonic chick neural retina cells. Neural retina cells, recovered from the dissociation procedure, were cultured on a gyratory shaker and the aggregate diameters formed in the ...

ROLE OF ELECTRIC SURFACE CHARGE OF CELL MEMBRANE IN PHAGOCYTOSIS

Acta Pathologica Japonica, 1973
An attempt to clarify the role of surface charge on cell membrane was performed on two cell types, phagocytic (rat peritoneal macrophage) and non‐phagocytic cells (Ehrlich ascites tumor cell). The electrophore‐tic mobility of both cells was remarkably reduced by the treatment with protamine sulfate, and diminished considerably by the increase of ionic ...

Free radicals as probes of cell surface charge

Journal of Electrostatics, 1988
Abstract Surface charge plays an important role in determining the energetics of biomembrane interactions and influences the electrical field that acts across the lipid bilayer and its intrinsic proteins. Electron spin resonance spectroscopy can be employed to estimate surface charge either through the use of amphiphilic spin label probes or by the ...

Distribution of cell surface charges on mesothelium and lymphatic endothelium

Microvascular Research, 1986
The distribution of anionic sites on the luminal surfaces of the peritoneal mesothelium and lymphatic endothelium was investigated by injecting cationized ferritin (CF) intraperitoneally. After washing with phosphate-buffered saline, the diaphragm was fixed and processed for electron microscopy.
