Interleukin-10 prevents glutamate-mediated cerebellar granule cell death by blocking caspase-3-like activity.
Interleukin-10 (IL-10) has been shown to reduce neuronal degeneration after CNS injury. However, the molecular mechanisms underlying the neuroprotective properties of this cytokine are still under investigation. Glutamate exacerbates secondary injury caused by trauma. Thus, we examined whether IL-10 prevents glutamate-mediated cell death. We used rat cerebellar granule cells in culture because ...
متن کاملThe role of Bax and caspase-3 in doppel-induced apoptosis of cerebellar granule cells
Doppel (Dpl) protein is a paralog of the prion protein (PrP) that shares 25% sequence similarity with the C-terminus of PrP, a common N-glycosylation site and a C-terminal signal peptide for attachment of a glycosylphophatidyl inositol anchor. Whereas PrP (C) is highly expressed in the central nervous system (CNS), Dpl is detected mostly in testes and its ectopic expression in the CNS leads to...
متن کاملActivation of a caspase 3-related cysteine protease is required for glutamate-mediated apoptosis of cultured cerebellar granule neurons.
Neurotoxicity induced by overstimulation of N-methyl-D-aspartate (NMDA) receptors is due, in part, to a sustained rise in intracellular Ca2+; however, little is known about the ensuing intracellular events that ultimately result in cell death. Here we show that overstimulation of NMDA receptors by relatively low concentrations of glutamate induces apoptosis of cultured cerebellar granule neuron...
متن کاملCaspase activation cascades in apoptosis.
Apoptosis, a highly controlled mode of cell death, is utilized to eliminate superfluous, aged, injured or infected cells from the body. Caspases, a family of aspartic acid-specific proteases, are the major effectors of apoptosis. To curtail their activity, caspases are normally synthesized as inactive precursors, but become activated at the onset of apoptosis by activation signals. Once active,...
متن کاملActivation of Caspase-3 in Radioinduced Apoptosis in Developing Brain
ICE/ced-3 related proteases (caspases) have been implicated in programmed cell death in a wide variety of cell types. However, their roles in radiation-induced cell death in cultures of mixed, neuronal and glial precursors cells are poorly understood. In order to further elucidate the molecular mechanisms underlying radiation induced death in this system; we have examined the ability of ionizin...
