SummaryThe accumulation of the lipophilic cation, triphenylmethylphosphonium, has been employed to determine the resting membrane potential in human erythrocytes, turkey erythrocytes, and rat white adipocytes. The triphenylmethylphosphonium cation equilibrates rapidly in human erythrocytes in the presence of low concentrations of the hydrophobic anion, tetraphenylborate. Tetraphenylborate does not accelerate the uptake of triphenylmethylphosphonium ion by adipocytes. The cell associatedvs… 
Triphenylmethylphosphonium cation distribution as a measure of hormone-induced alterations in white adipocyte membrane potential
TLDR
It is suggested that intracellular free fatty acid accumulation in response to lipolytic agents causes dissipation of the mitochondrial membrane potential and efflux of [3H]TPMP+ from the organelle and cell.
Permeability change in transformed mouse fibroblasts caused by ionophores, and its relationship to membrane permeabilization by exogenous ATP
TLDR
The effects exerted by electrogenic ionophores on the plasma membrane were found to be similar to those induced by exogenous ATP, whereas ATP effects are specific for transformed cells, and it is postulated that ATP actsvia specific sites on the surface of transformed cells.
Erythrocyte plasma membrane potential: past and current methods for its measurement
TLDR
This article summarizes the methodologies used during the past decades to determine Δψ in red blood cells, from seminal microelectrodes, through the use of nuclear magnetic resonance or lipophilic radioactive ions to quantify intra and extracellular ions, to continuously renewed fluorescent potentiometric dyes.
Transport of hydrophobic ions in erythrocyte membrane: I. Zero membrane potential properties
TLDR
TPA flux is stimulated by substoichiometric amounts of tetraphenylboron and other organic anions, suggesting an ion-pairing mechanism, and no evidence for facilitated transport could be found.
Cation channels, cell volume and the death of an erythrocyte
TLDR
Beyond their role in the limitation of erythrocyte survival, cation channels may contribute to the triggering of apoptosis in nucleated cells exposed to osmotic shock and/or oxidative stress.
Membrane potential and ion partitioning in an erythrocyte using the Poisson-Boltzmann equation.
TLDR
To investigate how much the dispersion forces contribute to active ion pumps in an erythrocyte (red blood cell) as well as the correction of chemical potential reference states between intracellular and extracellular environments, the modified Poisson-Boltzmann equation is analyzed.
TRPC6 Contributes to the Ca2+ Leak of Human Erythrocytes
TLDR
Human and mouse erythrocytes express TRPC6 cation channels which participate in cation leak and Ca2+-induced suicidal death.
Isoosmotic shrinkage by self-stimulated outward Na-K-Cl cotransport in quail erythrocytes
TLDR
Isoosmotic hypokalaemia drives a rapid shrinkage of quail erythrocytes, due to auto-catalytic net outward cotransport stimulation.
On the physiological and cellular homeostasis of ascorbate
TLDR
The proposed approach provides, for the first time, a mechanistic account of processes leading to ascorbate physiological and cellular distribution, which helps to explain numerous experimental and clinical observations.

TLDR
A primary mode of action of thyrotropin on the thyroid cell may be an alteration in the electrical potential across the plasma membrane, and the relevance of this observation to the mechanism ofaction of other glycoprotein hormones, certain bacterial toxins, and interferon is discussed.
The effects of ionophores on the fluorescence of the cation 3,3'-dipropyloxadicarbocyanine in the presence of pigeon erythrocytes, erythrocyte 'ghosts' or liposomes.
TLDR
The results were consistent with the suggestion of Sims, Waggoner, Wang & Hoffman that the dye was bound at both membrane surfaces and that, at low dye concentrations, hyperpolarizing the cells promoted dye binding at the inner membrane surface.
The membrane potential of Ehrlich ascites tumor cells microelectrode measurements and their critical evaluation
TLDR
Intracellular potentials were measured using a piezoelectric electromechanical transducer to impale Ehrlich ascites tumor cells with capillary microelectrodes to conclude that the peak potentials represent the membrane potential of the unperturbed cell, and that chloride is in electrochemical equilibrium across the cell membrane.
Cellular energy metabolism, trans-plasma and trans-mitochondrial membrane potentials, and pH gradients in mouse neuroblastoma.
TLDR
Comparing the results of the microelectrode and equilibrium measurements permits estimates of the electrical potential and pH gradients across the mitochondrial membrane (mitochondria-to-cytoplasm gradients) to be made and suggests that the trans-mitochondrial membrane protonmotive force in the intact cell cannot be greater than -143 mV.

TLDR
An in vitro action of tetanus toxin on the synaptosomal membrane that can be correlated with biological potency in vivo and is consistent with the in vivo effects of tetanos toxin on neuronal transmission is defined.
The Determination of the Membrane Potential of Chlorella vulgaris
TLDR
The results demonstrate that sugar uptake in Chlorella is electrogenie and the ΔpH plus membrane potential measured for Chloreella completely cover the energy required to explain the 1600-fold accumulation of' 6-deoxyglucose experimentally observed.
The relation between dicarbocyanine dye fluorescence and the membrane potential of human red blood cells set at varying Donnan equilibria
TLDR
The equilibrium calibration of dye fluorescence, when applied to diffusion potentials induced by 1 microM valinomycin, yields a value for the permeability ratio, PK.VAL/PCl, in agreement with previous estimates by other methods.

TLDR
The data suggest that DeltaPsi is involved in primary triggering of phagocytic cells and that metabolic stimulation is a secondary consequence of ligand-receptor interactions.
Mechanism of monensin-induced hyperpolarization of neuroblastoma-glioma hybrid NG108-15.
TLDR
The hyperpolarizing effect of monensin is mediated apparently by an increase in intracellular Na+ that acts to stimulate the electrogenic activity of the Na+,K+-ATPase.
