Marinesco bodies (MBs) are spherical eosinophilic intranuclear inclusions in pigmented neurons in the substantia nigra and locus ceruleus. Previous immunohistochemical studies have shown that MBs are positive for ubiquitin, p62 and SUMO-1, suggesting the involvement of ubiquitination and related proteins in the formation or disaggregation of MBs. However, the involvement is not thoroughly understood. Therefore, we immunohistochemically examined the midbrain from five control subjects ranged from 53 to 84 years old. MBs were positive for various proteins implicated in the ubiquitin-proteasome system (ubiquitin, p62, EDD1, NEDD8, NUB1, SUMO-1 and SUMO-2), aggresome formation (HDAC6) and autophagy (ubiquitin, p62, LC3, GABARAP and GATE-16). These findings suggest that proteins related to ubiquitination, proteasomal degradation and autophagy are involved in the formation or disaggregation of MBs.
