In this study we have used mature, primary cultured mouse cerebellar granule cells (CGCs) to initiate our studies on the mechanisms governing neuronal trafficking of GABAA receptors (GABARs). Initially the steady-state distribution of GABAR alpha1, alpha6, beta2 and beta3 subunits between the cell surface and cell interior was quantified. Cell surface(More)
Mouse cerebellar granule cells (CGCs) were cultured in either non-depolarising (5 mM KCl, '5K') or depolarising (25 mM KCl, '25K') media. CGCs at 5K developed an elaborate network of processes and formed compact cell aggregates, whilst at 25K, cell aggregation was rarely observed. GABA(A) receptor (GABAR) expression was significantly affected by the culture(More)
NMDA receptors were immunopurified from adult mouse forebrain and screened by immunoblotting. NR1 was co-associated with NR2A, NR2B and NR2D but not NR2C, nor was NR2C detected in adult mouse hippocampal membranes. The anatomical distribution of NR1, 2A, 2B and 2D was mapped in the adult murine hippocampal formation. NR1-like immunoreactivity was localised(More)
The distributions of the N-methyl-D-aspartate (NMDA) receptor NR1, NR2A, NR2B and NR2C/D subunits were mapped in adult mouse cerebellum using subunit-specific antibodies. Immunostaining with anti-NR1 antibodies was prominent in cell bodies and dendritic arbors of Purkinje cells, was light to moderate in cerebellar granule cells, Golgi interneurons and(More)
