Striated muscle represents one of the best models for studies on Ca(2+) signalling. However, although much is known on the localisation and molecular interactions of the ryanodine receptors (RyRs), far less is known on the localisation and on the molecular interactions of the inositol trisphosphate receptors (InsP(3)Rs) in striated muscle cells. Recently,(More)
The subcellular distribution of endoplasmic reticulum proteins (IP3R1 and RYR), plasma membrane (PM) proteins (mGluR1 and PMCA Ca(2+)-pump), and scaffolding proteins, such as Homer 1b/c, was assessed by laser scanning confocal microscopy of rat cerebellum parasagittal sections. There appeared to be two classes of Ca2+ stores, nonjunctional Ca2+ stores and(More)
We carried out immunohistochemical studies on cerebellar Purkinje cells in sporadic olivopontocerebellar atrophy (OPCA) and in granule cell-type cerebellar degeneration (gc-CD). The cell bodies, axons and dendrites including spiny branchlets and dendritic spines of normal Purkinje cells were intensely stained by the antibody against P400(More)
