Impaired Cl- homeostasis in isolated OSNs. A, 2P-FLIM images from isolated rat OSNs loaded with MQAE, sorted by the [Cl-]i in their dendritic knobs. [Cl-]i ranges from 20 to 60 mm. The extracellular Cl- concentration was 150 mm. Scale bar, 10 μm. B, Distribution of [Cl-]i values in dendritic knobs of isolated OSNs (blue histogram; 30 ± 8 mm; 100 cells) and in knobs in intact epithelium (red histogram; 62 ± 6 mm; 39 cells) in the presence of 150 mm extracellular Cl-. Most isolated OSNs showed a reduced ability to accumulate Cl-.
