    Occurrence, distribution and nature of neuropeptide Y in the rat pancreas (1985)
    Springer
    Cellular and molecular life sciences 41 (1985), S. 1554-1557 
    Details
    ISSN: 1420-9071
    Keywords: Immunocytochemistry ; neuropeptide Y ; radioimmunoassay ; rat pancreas
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Significant quantities of a newly discovered peptide, neuropeptide Y, were found in the rat pancreas, where they were localized to nerves in the exocrine parenchyma and around arterial and ductal structures. Although unaffected by surgical parasympathectomy, the periarterial and periductal nerves were abolished by chemical sympathectomy, suggesting that NPY is partially costored with sympathetic transmitters in nerve fibers.

    Immunocytochemical demonstration of calmodulin in cells secreting by exocytosis (1985)
    Springer
    Cellular and molecular life sciences 41 (1985), S. 1340-1342

    ISSN: 1420-9071
    Keywords: Immunocytochemistry ; calmodulin ; secretory granules

    Topics: Biology , Medicine
    Notes: Summary Calmodulin is a regulator of several calcium-dependent cellular processes. It has been suggested that it plays a role in the mechanism of secretion. Employing an indirect immunoperoxidase technique at the light microscope level, this study demonstrates the presence of calmodulin in several exocytotic cells (mast cells, thyroid follicular cells, neurohypophyseal neurosecretory terminals, pancreaticβ-cells and pancreatic acinus cells) in rat and man. The positive staining reaction for calmodulin was granular and at least in the case of rat mast cells it appeared to be associated with the granule membrane.

    Demonstration of enamel matrix proteins on root-analogue surfaces of rabbit permanent incisor teeth (1977)
    Springer
    Calcified tissue international 24 (1977), S. 223-229

    Topics: Biology , Medicine , Physics
    Notes: Summary The continuously erupting rabbit incisor tooth is normally thought of as having an enamel covered “crown” on its labial surface and a cementum covered “root” on its lingual surface. We have examined both surfaces of continuously erupting rabbit incisor teeth taken from near term embryos by a variety of means, including transmission and scanning electron microscopy, biochemical fractionation, and immunohistochemistry. In all cases, we could detect no qualitative difference in the early extracellular matrices taken from the labial and lingual surfaces of the teeth. Both matrices were shown to be composed of dentin and enamel, although the thickness and geometry of the enamel matrix on the lingual surface was somewhat different from that on the labial surface.

    Keywords: Hansenula polymorpha ; Peroxisomes ; Methanol ; Dihydroxyacetone synthase ; Cell fractionation ; Immunocytochemistry

    Topics: Biology
    Notes: Abstract The subcellular localization of dihydroxyacetone synthase (DHAS) in the methylotrophic yeast Hansenula polymorpha was studied by various biochemical and immunocytochemical methods. After cell fractionation involving differential and sucrose gradient centrifugation of protoplast homogenates prepared from methanol-grown cells, DHAS cosedimented with the peroxisomal enzymes alcohol oxidase and catalase. Electron microscopy of this fraction showed that it contained mainly intact peroxisomes, whereas SDS-polyacrylamide gel electrophoresis revealed two major protein bands (75 and 78 kDa) which were identified as alcohol oxidase and DHAS, respectively. The localization of DHAS in peroxisomes was further established by immunocytochemistry. After immuno-gold staining carried out on ultrathin sections of methanol-grown H. polymorpha using DHAS-specific antibodies, labelling was confined to the peroxisomal matrix.

    Notes: Abstract The major albumin protein in storage parenchyma tissue of developing peas has been localised at an ultrastructural level by immunocytochemistry. Tissue was fixed in buffered aldehyde and embedded in LR White resin which was polymerised by addition of catalyst. Sections were labelled by the indirect method of absorption of Protein A-gold to specifically bound antibodies. This method gives high levels of specific labelling on sections which retain good ultrastructural preservation and have high contrast after conventional staining. The albumin is located throughout the cytoplasm although no labelling was found associated with the endoplasmic reticulum, Golgi apparatus, vacuoles-protein bodies or other organelles.

    Immunocytochemical localization of phaseolin and phytohemagglutinin in the endoplasmic reticulum and Golgi complex of developing bean cotyledons (1985)
    Springer
    Planta 164 (1985), S. 295-302 
    Details
    ISSN: 1432-2048
    Keywords: Cotyledon ; Golgi complex ; Immunocytochemistry ; Phaseolus (seed proteins) ; Phaseolin ; Phytohemagglutinin ; Protein (seeds)
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Development of legume seeds is accompanied by the synthesis of storage proteins and lectins, and the deposition of these proteins in protein-storage vacuoles (protein bodies). We examined the subcellular distribution, in developing seeds of the common bean, Phaseolus vulgaris L., of the major storage protein (phaseolin) and the major lectin (phytohemagglutinin, PHA). The proteins were localized using an indirect immunocytochemical method in which ultrathin frozen sections were immunolabeled with rabbit antibodies specific for either PHA or phaseolin. Bound antibodies were then localized using goat-anti-rabbit immunoglobulin G adsorbed onto 4- to 5-nm colloidal gold particles. The sections were post-fixed with OsO4, dehydrated, and embedded in plastic on the grids. Both PHA and phaseolin exhibited a similar distribution in the storage-parenchyma cells, being found primarily in the developing protein bodies. Endoplasmic reticulum and Golgi complexes (cisternal stacks and associated vesicles) also were specifically labeled for both proteins, whereas the cytosol and other organelles, such as mitochondria, were not. We interpret these observations as supporting the hypothesis that the transport of storage proteins and lectins from their site of synthesis, the rough endoplasmic reticulum, to their site of deposition, the protein bodies, is mediated by the Golgi complex.

    Topics: Biology , Medicine
    Notes: Summary Antiserum generated against synthetic urotensin II of the goby, Gillichthys mirabilis, was used to localize urotensin II in the caudal neurosecretory system in six species of freshwater teleosts; Cyprinus carpio, Carassius auratus, Oreochromis mossambicus, Oreochromis niloticus, Salmo gairdneri and Plecoglossus altivelis, and six species of seawater teleosts: Acanthogobius flavimanus, Pagrus major, Paapristipoma trilineatum, Trachurus japonicus, Seriola dumerili and Seriola quinqueradiata. In the carp, urotensin II-immunoreactive perikarya were classified into three groups according to their size and shape. Small cells were located in the spinal cord dorsal to the urophysis, medium-sized cells immediately anterior to the urophysis, and large cells anterior to the medium-sized cells. In each group, a small number of nonreactive cells was found. Urotensin II-immunoreactive nerve fibers extended toward the urophysis and terminated around the blood vessels. Other species of teleosts showed a similar immunoreaction to that observed in the carp. The immunoreaction of the urophysis was stronger in seawater fish than freshwater fish. Urotensin II-immunoreactive elements could not be detected in the brains of the carp, goldfish and goby.

    Luteinizing hormone —Releasing hormone (LH-RH) pathway of the rat hypothalamus revealed by the unlabeled antibody peroxidase-antiperoxidase method (1974)

    Topics: Biology , Medicine
    Notes: Summary Utilizing the unlabeled antibody enzyme method, we report the distribution of hypothalamic elements immunoreactive with antibodies to luteinizing hormone-releasing hormone (LH-RH) in the rat. Immunostained elements, resembling neural processes, were distributed along a pathway corresponding to the tuberoinfundibular tract which appeared to terminate near vascular elements in the external layer of the preand post-infundibular median eminence. No cell bodies stained specifically for LH-RH. Similar topographic arrangements were noted (in coronal and sagittal sections) in diestrous females, ovariectomized females and a hypophysectomized male. The same results were obtained with three different preparations of antisera to LH-RH. Our studies agree with those of other investigators using immunohistochemical techniques as well as with localization studies of LH-RH in the hypothalamus using bioassay and radioimmunoassay. Our results suggest that the unlabeled antibody enzyme technique will have unique value for identifying and tracing fiber systems related to specific functions within the hypothalamus.

    Autoradiographic studies of 3H-dexamethasone uptake by immunocytochemically characterized cells of the rat pituitary (1977)

    Keywords: Pituitary ; Dexamethasone ; ACTH ; Autoradiography ; Immunocytochemistry
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary 3H-Dexamethasone (10 μg/kg) was injected intravenously in adrenalectomized rats and after survival times of 5, 30, 60, and 180 min its uptake within the pituitary was studied by autoradiography. Radioactivity was concentrated in cell nuclei in the pars nervosa and pars distalis. Within the pars intermedia, only cells of the marginal zone were labeled. In the pars distalis, some cells showed a weak nuclear accumulation of radioactivity as early as 5 min after injection. The tissue radioactivity was nearly maximal at 5 min, and the proportion of radioactivity in nuclei reached a maximum of 60–70% by 30 min. In competition experiments, non-radioactive steroids (1 mg/kg) were injected 5 min before 3H-dexamethasone and sacrifice was 30 min later. Dexamethasone markedly diminished the nuclear accumulation in the pars distalis, but corticosterone and progesterone did not. In the pars nervosa, corticosterone and progesterone competed for nuclear uptake of 3H-dexamethasone, although less effectively than dexamethasone itself. Different cell types in the pars distalis were characterized by treating autoradiograms with an immuno-peroxidase bridge procedure. Cells treated with anti-ACTH 17–39 had the greatest nuclear concentration of radioactivity, and those stained with anti-TSH were least heavily labeled. Cells treated with antisera to GH, PRL, and hCG were moderately labeled.

    Immunocytochemical demonstration of retinal S-antigen in the pineal organ of four mammalian species (1985)

    Keywords: Pineal organ (mammals) ; Retinal S-antigen ; Photoreceptors ; Retina ; Immunocytochemistry
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary By means of immunocytochemistry retinal S-antigen is selectively demonstrated in retinal photoreceptor cells of the rat and in pinealocytes of the hedgehog, rat, gerbil and cat. Brain areas surrounding the pineal organ are immunonegative. The immunoreactive material is evenly distributed in the perikarya of the cells. Occasionally, inner segments of retinal photoreceptors and processes of pinealocytes are also stained. The outer segments of retinal photoreceptors display a strong immunoreaction. In both pinealocytes and retinal photoreceptors the intensity of the immunoreaction varied considerably among individual cells. The immunocytochemical demonstration of retinal S-antigen in mammalian pinealocytes indicates that these cells still bear characteristics of photoreceptors. This finding is in accord with the concept that mammalian pinealocytes are derived from pineal photoreceptor cells of poikilothermic vertebrates.
