Furthermore, because TRPML currents are strongly rectifying at the inward direction, cellular cues can also regulate TRPML-mediated Ca2+ release by modulating lysosomal ∆ψ a driving force for Ca2+ release (Cheng et al., 2010; Dong et al., 2010a, b).
In the absence of any divalent cations in the bath solution, e.g. with the current carried by Na+, large and strongly inward rectifying currents were measured which reversed close to 0 mV.
The shape of the current/voltage relationship for SK3 channels is strongly inwardly rectifying (Grunnet et al, 2001).
However, adenosine at 10 4 and 10 3 M did open a novel strongly outwardly rectifying current (Fig. 2A).
In vivo current, generated by TRPM7 channels, is strongly outwardly rectifying, due to a blockage by cytosolic Mg2+ and, possibly, some additional internal factor [ 213].
The human CLC-5 is an electrogenic voltage-dependent 2Cl−/1H+ exchanger that gives rise to strongly outwardly rectifying currents when expressed.
However, the activation properties differ somewhat to the CLC Cl− channels: activation is strongly outwardly rectifying with no detectable currents at negative potentials (2, 22) and lowering extracellular pH reduces CLC-5 currents (2).
Substitution of external Na+ for NMDG+ strongly augmented the outwardly rectifying current, an observation consistent with increased activity of reversed NCXpm.
When NAGly (10 μM) was applied to histamine-stimulated cells without prior exposure to Na+-free solution, it abolished the outwardly rectifying current stimulated by histamine and strongly suppressed basal NCXpm currents.
This may be rectified by eating lightly prior to practice (overeating is strongly discouraged).
Her hair removal bit (aptly recorded while driving in the car) centers on her internal debate as she's on her way to get her eyebrows waxed, and how to rectify that decision with the old voice in her head that strongly resisted changing her appearance.
