WebThe resting free Ca 2+ concentration of astrocytes is ~ 100 nM 23: we clamped astrocyte Ca 2+ at about 35, 120, 310 and 500 nM using BAPTA. First , we found that clamping astrocyte Ca 2+ to ~120 nM produced no effect on interneuron mIPSC amplitudes ( Fig. 4g ), showing that patching and dialyzing astrocytes per se does not reduce mIPSCs and that clamping … WebAccordingly, the functional properties of astrocytes measured via cell patch-clamp experiments reveal that PnNs do not alter the bioelectrical properties of resting astrocytes, thus setting the scene for the use of PnN-loaded nanofibres as bioconductive platforms for interfacing astrocytes and controlling their bioelectrical properties.
