About ten years ago, structured illumination microscopy (SIM) was introduced as an alternative method for obtaining optical sections from biological specimens. Here we compare the resolution of the ApoTome (commercial SIM by Zeiss) to that achieved by a cLSM (Zeiss LSM 510). If fluorescent beads are used as test objects, then the ApoTome will achieve a lower axial resolution than the cLSM. In contrast to that, its lateral resolution scores slightly better. If subresolution homogeneous fluorescent layers are used as test objects, then the ApoTome will achieve a higher axial resolution than the cLSM. The ApoTome's axial resolution is homogeneous over the field-of-view while that of the cLSM changes markedly. Finally, the anisotropy of the ApoTome's resolution was found to be negligible for standard applications while its capability to resolve fine structures within stained tissue slices is limited to one or two cell layers and thus worse than in the cLSM.

Recently it has been shown that members of this protein family interfere with fluorescent (calcium indicator) dye uptake in taste buds of rat and in cells in the olfactory epithelium of larval Xenopus laevis, including olfactory receptor neurons. It has, however, not been resolved whether this effect only serves to extrude xenobiotics in sensory taste and olfactory cells, or alternatively, whether it is a more general feature of many central nervous system neurons. In the latter case blocking these transporters would improve fluorescent dye uptake in general. Here we show, by means of cell imaging. that also neurons of the olfactory bulb express multidrug resistance transporters, whereby a marked inhomogeneity among cells in the main and accessory olfactory bulb was observed. Blocking these transporters improved the net uptake of fluorescent dyes not only in cell somata of the olfactory bulb, but especially in fine neuronal structures such as individual dendrites or olfactory glomeruli, which consist of a tangle of tiny neuronal processes. We therefore suggest that the expression of multidrug resistance proteins may be common in cells of the central nervous system, and that the application of specific transport inhibitors could generally improve fluorescent dye uptake in brain slices, thereby improving calcium imaging conditions.

Here, we thoroughly characterize ATP-induced responses in SCs of the OE using functional Ca(2+) image The initial ATP-induced increase of the intracellular Ca(2+) concentration [Ca(2+)](i) always occurred in the apical part of SCs and subsequently propagated toward the basal lamina, indicating the occurrence of purinergic receptors I the apical part of SCs. The mean propagation velocity of the Ca(2+) signal within SCs was 17.10 +/- 1.02 mu m/s. ATP evoked increases in [Ca(2+)](i) in both the presence and absence of extracellular Ca(2+). Depletion of the intracellular Ca(2+) stores abolished the responses. This shows that the ATP-induced [Ca(2+)](i) increases were in large part, if not entirely, due to the activation of G protein-coupled receptors followed by Ca(2+) mobilization from intracellular stores, suggesting an involvement of P2Y receptors. The order of potency of the applied purinergic agonists was UTP > ATP > ATP-gamma S (with all others being only weakly active or inactive). The ATP-induced [Ca(2+)](i) increases could be reduced by the purinergic antagonists PPADS and RB2, but not by suramin. Our findings suggest that extracellular nucleotides in the OE activate SCs via P2Y(2)/P2Y(4)-like receptors and initiate a characteristic intraepithelial Ca(2+) wave.

The spontaneous [Ca(2+)] activities of M/T cells appeared to be irregular, but there were groups of spatially distributed neurons showing synchronized [Ca(2+)] activities. These neurons were always connected to the same glomerulus. Odorants elicited complex spatiotemporal response patterns in M/T cells where nearby neurons generally showed little correlation. But the responses of neurons connected to the same glomerulus were virtually identical, irrespective of whether the responses were excitatory or inhibitory, and independent of the distance between them. Synchronous neurons received correlated EPSCs and were coupled by electrical conductances that could account for the correlated responses.
