| Research Abstract |
Neurolathyrism (NL), a motoneuron disease, is caused by the overconsumption of grass pea that is a draught-tolerant crop containing a neurotoxin L-β-ODAP. Under the unavoidable deficiencies of sulfur-containing amino acids and glutathione, I clarified the induction of nonspecific cation channels TRPM2 and 7 in cultured cells and in the spinal cord of a NL-model rat. In the model, there observed the vessel disruption and hemorrhage in the lower spinal cord where heme oxygenase-1 was highly induced to cause pathological changes.
