Calretinin unipolar brush cells

Rogers, 1992 Braak and Braak, 1993 Floris et al., 1994). Calretinin-immunoreactivity in unipolar brush cells was used for a detailed characterization of this cell type, and to... 

Fig. 68. Immuno-electron micrograph of an unipolar brush cell stained with antiserum to calretinin. The micrograph was obtained near the surface of the immunoreacted slice, as indicated by open areas in the tissue and over the cell nucleus (stars). The unipolar cell body has an irregular contour. The nucleus (N) shows a deep indentation (T) and the cytoplasm contains an array of ringlet subunits (R). The short dendrite forms an extensive synapse (arrows) with a calretinin-negative mossy fiber ending (mO. At tbe aspect opposite the synapse the dendrite contains numerous mitochondria. Granule cells (CG) are immunonegative. Bar = 1 fim. Floris et al. (1994).

Fig. 146. Parasagittal section of the rat cerebellar vermis immunostained with antiserum to calretinin. Folia are labelled with roman numerals according to Larsell. The pattern of immunoreactivity in the nodulus (lobule X) and portion of the ventral uvula (lobule IXd) differs from that in the other vermal folia. While in most of the vermis weak immunoreactivity is present in granule cell bodies within the granular layer and in parallel fibers within the molecular layer, in the folia X and IXd of the vestibulo-cerebellum the immunoreaction product is largely localized in unipolar brush cells and mossy fibers, MN, medial cerebellar nucleus. Bar = 1 mm. Floris et al. (1994).
