IgGs from sera containing antiphospholipid antibodies (aPL), detected as antibodies to cardiolipin, or control sera were incubated with rat cerebellar granule cells in primary culture. Using a mitochondrial dehydrogenase activity assay (MTT test), aPL IgGs were shown to decrease MTT metabolism after 24 h incubation with the cells, and to cause non-toxic(More)
Cerebellar granule cells cultured in the presence of a differentiating factor isolated from rabbit serum exhibit, at variance with those cultured in fetal calf serum, an almost complete resistance to excitatory aminoacid (EAA)-induced cytotoxicity. We investigated the behaviour of protein kinase C (PKC), strongly implicated in EAA cytotoxicity, in the two(More)

Carbon monoxide as a novel neuroendocrine modulator: inhibition of stimulated CRH release from acute rat hypothalamic explants. Evidence that carbon monoxide stimulates prostaglandin endoperoxide synthase activity in rat hypothalamic explants and in primary cultures of rat hypothalamic astrocytes. Activation of heme oxygenase and consequent carbon monoxide(More)
Excitatory amino acids which promote the survival of cerebellar granule cells in culture, also promote the expression of the survival of motor neuron (SMN) protein. Immunolocalization studies using SMN monoclonal antibody showed that SMN is decreased in cultures grown in low K+ or chemically defined medium with respect to cultures grown in high K+ medium(More)
The possible modulation of nitric oxide (NO) synthase (NOS) activity by protein kinase C (PKC) was investigated in primary cultures of rat cerebellar neurons. Incubation of the cells with L-arginine and nicotinamide-adenine dinucleotide phosphate (NADPH) produced detectable levels of NO, as quantified by photometric assay [0.14 +/- 0.03 nmol/h/dish (2.5 x(More)
Protein phosphorylation in response to toxic doses of glutamate has been investigated in cerebellar granule cells. 32P-labelled cells have been stimulated with 100 microM glutamate for up to 20 min and analysed by one and two dimensional gel electrophoresis. A progressive incorporation of label is observed in two molecular species of about 80 and 43 kDa(More)
The neurite outgrowth and adhesion complex (NOAC), isolated from rabbit sera has been dissociated in its major components by reverse-phase chromatography in HPLC by using a C18 column. SDS-PAGE analysis of the active fractions revealed the presence of three major bands of approximately 100, 70 and 50 kDa. Studies on the biological activity of NOAC were(More)
