Recent studies have shown that \u03b1-Syn-immunoreactive Lewy pathology is characterized by membrane crowding, including vesicular structures. To elucidate the role of VAPB and vesicular structures in Parkinson\u2019s disease (PD) and in dementia with Lewy bodies (DLB), the relationships among VAPB, vesicular structures, and Lewy pathology were investigated by immunohistochemistry and immunoelectron microscopy in 8 PD and 4 DLB autopsy cases. The proportions of VAPB-negative neurons in the substantia nigra in PD and in the temporal cortex in DLB were significantly higher than those in 5 controls. In PD, the incidence of \u03b1-Syn inclusions in VAPB-negative neurons was significantly higher (77.4%) than in VAPB-positive neurons (1.6%) in the substantia nigra. In DLB, the incidence of \u03b1-Syn inclusions in VAPB-negative neurons was also significantly higher (65.3%) than in VAPB-positive neurons (2.8%) in the temporal cortex. Immunoelectron microscopy revealed that \u03b1-Syn and VAPB were localized to filamentous structures of Lewy bodies (LBs). However, only a few vesicular structures labeled with anti-\u03b1-Syn were observed within LBs. These findings suggest that reduction of VAPB is involved in the disease processes of PD and DLB, although vesicular structures may not directly contribute to the formation of LBs.<\/jats:p>","DOI":"10.1093\/jnen\/nlac070","type":"journal-article","created":{"date-parts":[[2022,8,11]],"date-time":"2022-08-11T14:28:36Z","timestamp":1660228116000},"page":"807-815","source":"Crossref","is-referenced-by-count":4,"title":["Alteration
