    Membrane properties of OECs from the human olfactory mucosa are comparable to those from the rat olfactory mucosa. A Whole-cell voltage clamp recording from a representative human OEC following three days in vitro (3 DIV), showing membrane currents activated by sequential 200 ms voltage steps between −153 mV and 17 mV, in 10 mV increments from a holding potential of −73 mV. Hyperpolarizing steps activated large inward currents, whereas depolarizing steps typically activated outward currents. B Group (black squares) and individual (gray squares) I-V relationships of 11 human OECs after 1-3 DIV. C Normalized group and individual I-V plots demonstrated the weak voltage-dependence of the whole-cell currents. D Currents in a representative human OEC before (control) and after bath application of 100 µ M Ba 2+ . E Group I-V relationships before (open squares) and after (filled squares) Ba 2+ application in 6 OECs. F Bath applied Ba 2+ depolarized the resting membrane potential (V m ) of all cells reversibly. G Digital subtraction of the currents in the presence of Ba 2+ from control currents revealed a weak inwardly rectifying Ba 2+ -sensitive current. H Group (black squares) and individual (gray squares) I-V relationships of Ba 2+ -sensitive currents in six OECs. Inset , comparison of the Ba 2+ -sensitive component of whole-cell currents recorded in OECs from human OM and rat OM (group data shown in Fig 6H and Fig 1H , respectively).

    Functional implications of homomeric Kir4.1 and heteromeric Kir4.1/Kir5.1 channels in oligodendrocytes. Oligodendroglial expression of Kir4.1 channels indicates they may be important in uptake of excess K + released during axonal action potential propagation, a function largely attribiuted to astrocytes. Due to their wrapping of axons, oligodendrocytes are exposed to large ionic and pH shifts during axonal electrical activity, and it is likely weakly rectifying homomeric Kir4.1 and strongly rectifying Kir4.1/Kir5.1 heteromeric channels are important in maintaining the negative resting membrane potential, which is essential for oligodendroglial and myelin integrity. Weakly rectifying homomeric Kir4.1 channels may preferentially extrude K + and supply extracellular K + for the Na + –K + -pumps, as described in transporting epithelia. In contrast, the pH sensitivity of heteromeric Kir4.1/Kir5.1 channels is likely to have a role in the CO 2 /pH chemosensation in glia, involving carbonic anhydrase that is enriched in astrocytes and oligodendrocytes. Furthermore, intracellular acidification and inhibition of Kir4.1/Kir5.1 channels has been shown to trigger release of ATP from astrocytes, which would act on oligodendroglial P2X and P2Y receptors to provide a mechanism of astrocyte–oligodendrocyte signaling in response to metabolic challenges, which has important implications for white matter physiology and pathology

    Figure Lengend Snippet: OECs in the rat olfactory mucosa express Kir4.1 channel subunits. A Horizontal section of rat OM, immuno-labelled for the OEC marker S100 ( left ) and the neuronal marker tubulin ( center ). The overlay has cell nuclei counter-stained using DAPI ( right ). The cell bodies of OSNs reside within the olfactory epithelium (OE), and their axons fasciculate within lamina propria (LP). S100+ OECs lie beneath the basement membrane and in close association with SN axons. B and C show detail of a fascicle highlighted in A (*), labelled for S100 and βIII-tubulin ( B ), and for the weakly rectifying K + channel subunit Kir4.1 ( C ). D shows detail of fascicles where OSN axons are labelled using anti-OMP and OECs are labelled using anti-Kir4.1. Scale bars: A 50 µ m, B-D 20 µ m.

    Article Snippet: Antibodies The following primary antibodies were used for immunofluorescence: rabbit polyclonal anti-Kir4.1 (APC-035, Alomone Labs); guinea pig polyclonal anti-Kir4.1 (AGP-012, Alomone Labs); mouse monoclonal βIII-tubulin (subtype IgG2a ; clone TUJ1; Covance); rabbit polyclonal anti-S100 (Z0311; Dako); Goat polyclonal anti-OMP (Wako).

    Membrane properties of OECs from the human olfactory mucosa are comparable to those from the rat olfactory mucosa. A Whole-cell voltage clamp recording from a representative human OEC following three days in vitro (3 DIV), showing membrane currents activated by sequential 200 ms voltage steps between −153 mV and 17 mV, in 10 mV increments from a holding potential of −73 mV. Hyperpolarizing steps activated large inward currents, whereas depolarizing steps typically activated outward currents. B Group (black squares) and individual (gray squares) I-V relationships of 11 human OECs after 1-3 DIV. C Normalized group and individual I-V plots demonstrated the weak voltage-dependence of the whole-cell currents. D Currents in a representative human OEC before (control) and after bath application of 100 µ M Ba 2+ . E Group I-V relationships before (open squares) and after (filled squares) Ba 2+ application in 6 OECs. F Bath applied Ba 2+ depolarized the resting membrane potential (V m ) of all cells reversibly. G Digital subtraction of the currents in the presence of Ba 2+ from control currents revealed a weak inwardly rectifying Ba 2+ -sensitive current. H Group (black squares) and individual (gray squares) I-V relationships of Ba 2+ -sensitive currents in six OECs. Inset , comparison of the Ba 2+ -sensitive component of whole-cell currents recorded in OECs from human OM and rat OM (group data shown in Fig 6H and Fig 1H , respectively). I In a 3 DIV culture, an OEC co-labeled with anti-S100 ( left panel) and anti-Kir4.1 antibodies ( center ). The overlay ( right ) has cell nuclei counter-stained using DAPI (blue), and F-actin using phalloidin (cyan). Scale bar: 50 µ m.
