Hypoxia/ischemic brain injury accompanies an inflammatory response involving an activation of glial cells. This study, using an in vitro model, investigated the signaling mechanisms mediating hypoxic responses of the two glial cell types (astrocytes and microglia) in relation to the expression of inducible nitric oxide synthase (iNOS). In cultures of rat(More)
Hypoxia-ischemia (HI) may play a significant role in motor neuron death associated with the pathology of spinal cord injury and, perhaps, amyotrophic lateral sclerosis. The present study employs an in vitro model of HI to investigate the role of a stress kinase pathway, i.e., p38 MAP kinase, in cell death signaling in a motor neuron cell line, i.e., NSC34,(More)
