Feedback inhibitory circuits were characterized electrophysiologically in the CA3 region of organotypic rat hippocampal cultures. Pyramidal cells were impaled with sharp microelectrodes and brief depolarizing current pulses were injected intracellularly to elicit single action potentials. An inhibitory postsynaptic potential (IPSP) was observed at fixed(More)
We have recently reported that in astrocytoma cells the expression of interleukin-8 (IL-8) is upregulated by prostaglandin E2 (PGE2). Unfortunately, the exact mechanism by which this happens has not been clarified yet. Here, we have investigated whether IL-8 activation by PGE2 involves changes in DNA methylation and/or histone modifications in 46(More)
Blockage of gamma-aminobutyric acid (GABA)ergic synaptic transmission in mature hippocampal slice cultures for a period of 3 days with convulsants was shown previously to induce chronic epileptiform activity and to mimic many of the degenerative changes observed in the hippocampi of epileptic humans. The cellular mechanisms underlying the induction of this(More)
