| Outline of Final Research Achievements |
Previous study from our laboratory reported that the carbonyl stress in a subpopulation of schizophrenia (SZ) patients, leading to a failure of metabolic systems with plasma pentosidine accumulation and serum pyridoxal depletion. However the molecular mechanisms of the relationship between carbonyl stress and SZ are still unknown. We hypothesize that astrocytes may have a deficit in energy metabolism resulting in neuronal damage in SZ, which might be involved in SZ pathology in carbonyl stress context. As a first step of the study, we examined how pentosidine accumulation affects to neuron and astrocyte using human neuronal cells. Our strategy will provide important clues for understanding of SZ.
