14648077GPX1GPx12.2Among them GPx1 is considered as the major enzyme responsible for removing intracytoplasmic 
14648077GPX1GPx12.2Like Prx2 GPx1 needs glutathione reductase (GR) GR as a secondary enzyme as

14648077GPX1GPx12.2Discussion Under normal physiological conditions Prx2 and GPx1 immunoreactivities in the spinal cord anterior horns in humans and 
14648077GPX1GPx12.2Considering that endogenous Prx2 and GPx1 within the neuronal cytoplasm are extremely effective regulators of the 
14648077GPX1GPx12.2of the normal spinal motor neurons co-expressed both Prx2 and GPx1 confirms that these motor neurons maintain themselves using the intracellular 
14648077GPX1GPx12.2these motor neurons maintain themselves using the intracellular Prx2/GPx1 Prx2 GPx1 system that is the redox system 
14648077GPX1GPx12.2Intense co-expression of SOD1 Prx2 and GPx1 in neuronal LBHIs in both diseases was evident 
14648077GPX1GPx12.2mutant wild-type SOD1 as an antioxidant system and Prx2/GPx1 Prx2 GPx1 as a redox system 
14648077GPX1GPx12.2this in vivo milieu where mutant SOD1 exists Prx2 and GPx1 would aberrantly interact with the mutant SOD1 which is assumed 
14648077GPX1GPx12.2that there are neuronal LBHIs positive for SOD1 Prx2 and GPx1 in the milieu where mutant SOD1 exists but no LBHIs 
14648077GPX1GPx12.2conditions our study demonstrates an aberrant interaction of Prx2/GPx1 Prx2 GPx1 with mutant SOD1 the aggregation of which results in neuronal 
14648077GPX1GPx12.2In addition intra-inclusional co-aggregation of Prx2/GPx1 Prx2 GPx1 with mutant SOD1 causes the intracytoplasmic reduction of Prx2/GPx1, Prx2 
14648077GPX1GPx12.2with mutant SOD1 causes the intracytoplasmic reduction of Prx2/GPx1, Prx2 GPx1 thereby reducing the availability of the redox system 
14648077GPX1GPx12.2the aberrant interaction of cytotoxic mutant SOD1 with Prx2/GPx1 Prx2 GPx1 directly regulating a redox system our finding leads us to 
14648077GPX1GPx12.2us to speculate that not only co-aggregation of Prx2/GPx1 Prx2 GPx1 and SOD1 into LBHIs but also intracytoplasmic reduction of Prx2/GPx1 
14648077GPX1GPx12.2SOD1 into LBHIs but also intracytoplasmic reduction of Prx2/GPx1 Prx2 GPx1 in both diseases may partly contribute to the breakdown of 
14648077GPX1GPx12.2to be determined whether this aberrant interaction of Prx2/GPx1 Prx2 GPx1 with mutant SOD1 is a direct or an indirect effect
