Download Glycoprotein biosynthesis in developing cerebellar granule cell cultures
In the developing cerebellum, there is a burst of glycoprotein expression on the plasma membrane of the parallel fibres associated with the granule cells (Zanetta et al., ).
This phase coincides with an increase in the activity of some glycosidase enzymes (Zanetta et al., ), which may be involved in glycoprotein by: 5.
Cell cultures Cultures enriched in granule cells were prepared from the cerebella of 8-day-old rats according to Thangnipon et Cultures enriched in cerebellar astrocytes were prepared from 8-day-old rats which had been treated 2 days prior to sacrifice with hydroxyurea (2 mg/kg i.p.2"17).Cited by: 3.
MAG, its receptor (NgR1) and co-receptor (p75 NTR) are expressed in the cerebellum. To establish the role of MAG in developing CGNs, we started the investigation by studying the expression pattern of MAG, NgR1 and p75 NTR in CGNs in vivo and in vitro.
MAG was expressed in P2, P4, P7, P10, P14 and P60 cerebellar (Fig. 1a–c).MAG immunoreactivity was detected diffusely along the whole P2 and P4 Cited by: 1.

ABSTRACT The biosynthesis of the neural cell adhesion molecule (N-CAM) was studied in primary cultures of rat cerebral glial cells, cerebellar granule neurons, and skeletal muscle cells.
The three cell types produced different N-CAM polypeptide patterns. The proliferation of cerebellar granule cell precursors (CGCPs) in EGL, their differentiation into cerebellar granule cells (CGCs), and migration of CGCs toward IGL are tempo-spatially modulated [3,10,14].
Cell adhesion proteins, which play an important role in the morphogenesis of cerebellum, include immunoglobulin superfamily (IgSF) proteins. Background: Neurons in the central nervous system (CNS) are generated by symmetric and asymmetric cell division of neural stem cells and their derivative progenitor cells.
Cerebellar granule cells are the most abundant neurons in the CNS, and are generated by intensive cell division of granule cell precursors (GCPs) during postnatal development.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): ABSTRACT The biosynthesis of the neural cell adhesion molecule (N-CAM) was studied in primary cultures of rat cerebral glial cells, cerebellar granule neurons, and skeletal muscle cells.
The three cell types produced different N-CAM polypeptide patterns. Glial cells synthesized aMr polypeptide B. Cerebellar granule cells form the thick granular layer of the cerebellar cortex and are among the smallest neurons in the brain. (The term granule cell is used for several unrelated types of small neurons in various parts of the brain.) Cerebellar granule cells are also the most numerous neurons in the brain: in humans, estimates of their total number average around 50 billion, which means.
Ornithine Decarboxylase Activity During Development of Cerebellar Granule Neurons Article (PDF Available) in Journal of Neurochemistry 71(5) December with 21 Reads. Human Cerebellar Granule Cells (HCGC) Catalog # Cell Specification The development of the cerebellum involves a set of coordinated cell movements and two separate proliferation zones: the ventricular zone and the external granule cell layer (EGL), a rhombic-lip-derived progenitor pool .
Reelin (Reln) is a glycoprotein that in postnatal and adult mammalian brain is believed to be secreted from telencephalic GABAergic interneurons and cerebellar glutamatergic granule neurons into the extracellular matrix.
To address the question of whether Reln neurosecretion occurs via a regulated or a constitutive process, we exposed postnatal rat cerebellar granule neurons (CGNs). Electron microscopic immunocytochemistry revealed that around the peak of cerebellar neuronal migration (7-day-old rat), 9-O-acetyl GD3 was localized at the contact sites between migrating granule cells and radial glia in the external granular layer and prospective molecular layer.

Kruse 1 R. Mailhammer 1. During CNS development, multipotent neural stem cells give rise first to various kinds of specified precursor cells, which proliferate extensively before terminally differentiating into either neurons or glial cells. It is still not clear, however, whether the specified precursor cells are irreversibly determined to differentiate into their particular cell types.
Effects of a glycoprotein synthesis inhibitor on myelination were investigated in rat cerebellum. The glycoprotein synthesis inhibitor, tunicamycin (TM), was injected intracranially into newborn rats.
The activity of 2′,3′-cyclic nucleotide 3′-phosphodiesterase (CNPase) in the cerebellum was significantly reduced in 2-week-old animals and was restored to the normal level by age 3 weeks. Kensuke Nakahira's 44 research works with 1, citations and reads, including: Pleiotrophin mRNA is highly expressed in neural stem (progenitor) cells of mouse ventral mesencephalon and the.
Myelin-associated glycoprotein (MAG) binds to the nerve cell surface and inhibits nerve regeneration. The nerve cell surface ligand(s) for MAG are not established, although sialic acid-bearing glycans have been implicated. We identify the nerve cell surface gangliosides GD1a and GT1b as specific functional ligands for MAG-mediated inhibition of neurite outgrowth from primary rat cerebellar.
Cerebellar Granule Neurons (CGNs). Cell isolation and culture were as described (16). Cerebella were removed from postnatal day 4–5 Sprague–Dawley rats and dissociated enzymatically. CGNs were isolated by the two-step purification method of Hatten (17).

Many proteins control how cells are organised in your body. For example, a group of proteins called the neurotrophins help to control the life and death of brain cells. After a brain injury, neurotrophins can cause nerve cells to die by working together with another protein called p75NTR.
The p75NTR protein is also found in another type of brain cell called granule progenitor cells. Cerebellar development involves several cell populations, and cellular activities in the developing cerebellum are extremely dynamic.
Cell type specification of precursor cells, rapid cell proliferation, and cell migration/patterning occur during cerebellar development, which are thought to require tremendous energy supply and robust biosynthesis.
Primary cultures of granule neurons from the post-natal rat cerebellum provide an excellent model system for molecular and cell biological studies of neuronal development and function. The cerebellar cortex, with its highly organized structure and few neuronal subtypes, offers.
Analysis of the Nr-CAM/L1 double knockouts suggested defects in granule cells during cerebellar development.
To further test the involvement of Nr-CAM and L1 in granule cell development, we used a dissociated cerebellar culture that mimics the in vivo differentiation of granule and Purkinje cells (Hatten et al., ).
As the double mutant mice. Granule cells were dissociated from early postnatal mouse cerebella and labeled with a fluorescent dye probe PKH Small number of the labeled cells were mixed with cerebellar cortical microexplant cultures or transplanted into cerebellar cortical organotypic explants, and their time‐dependent morphological changes during cultures were examined with fluorescence microscopy.
Importantly, glucosylceramide synthase inhibitors do not directly affect glycoprotein biosynthesis, and P4 does not reduce cell viability or neurite outgrowth (30, 31). Because of the relatively rapid turnover of gangliosides on the surface of CGNs in culture (t 1/2 cell surface gangliosides.
