α-Synuclein is a defining, key component of Lewy bodies and Lewy neurites in Parkinson's disease (PD) and dementia with Lewy bodies (DLB), as well as glial cytoplasmic inclusions in multiple system atrophy (MSA). The distribution and spreading of these pathologies are closely correlated with disease progression. Recent studies have revealed that(More)
BACKGROUND α-Synuclein is the major component of filamentous inclusions that constitute the defining characteristic of Parkinson's disease, dementia with Lewy bodies and multiple system atrophy, so-called α-synucleinopathies. Recent studies revealed that intracerebral injection of recombinant α-synuclein fibrils into wild-type mouse brains induced(More)
Aggregates of abnormal proteins are widely observed in neuronal and glial cells of patients with various neurodegenerative diseases, and it has been proposed that prion-like behavior of these proteins can account for not only the onset but also the progression of these diseases. However, it is not yet clear which abnormal protein structures function most(More)
Sialic acids may modulate cell proliferation and gene expression, particularly in neural cells in vitro. However, the function of sialic acids in the central nervous system has not previously been examined. We examined whether N-acetylmannosamine (ManNAc) could improve object recognition and hippocampal cell proliferations in middle-aged mice. C56BL/6J mice(More)
