Cobalt prevents nitric oxide-induced apoptotic motoneuron death in vitro.

We studied the mechanism of nitric oxide (NO) toxicity in cultured rat spinal motoneurons. Treatment with the NO donor NOC-18 (NOC) resulted in slow motoneuron death, ending in apoptosis. The observed motoneuron death was completely prevented by hemoglobin. Treatment with inhibitors of the known intracellular targets of NO, soluble guanylate cyclase… CONTINUE READING
