Glial cytoplasmic inclusions (GCIs) were demonstrated by silver staining, immunocytochemistry and by electron microscopy in the central nervous system (CNS) of 11 patients with various combinations of striatonigral degeneration, olivopontocerebellar atrophy and Shy-Drager syndrome. Although their configuration in light microscope can sometimes resemble neurofibrillary tangles, their cellular localisation, measurements, ultrastructure, immunocytochemical characteristics and regional distribution… 
Immunocytochemical and ultrastructural studies of neuronal and oligodendroglial cytoplasmic inclusions in multiple system atrophy
TLDR
The studies demonstrate widespread distribution of NCIs in the central nervous system of MSA and suggest the same pathological process that forms the granule-associated filaments in axons may also be responsible for the formation of ubiquitin-positive thickened neurites.
The distribution and dynamic density of oligodendroglial cytoplasmic inclusions (GCIs) in multiple system atrophy: a correlation between the density of GCIs and the degree of involvement of striatonigral and olivopontocerebellar systems
TLDR
GCIs may represent the early changes in MSA and may be a useful neuropathological hallmark for diagnosis of MSA, even in cases with minimal OPCA and SND.
Argyrophilic ubiquitinated cytoplasmic inclusions of Leu-7-positive glial cells in olivopontocerebellar atrophy (multiple system atrophy)
TLDR
The observation that Leu-7-positive glial cells, mainly oligodendroglials cells, had argyrophilic ubiquitinated inclusions may be of significance for the evaluation of the pathology of OPCA(MSA).
Accumulation of tubular structures in oligodendroglial and neuronal cells as the basic alteration in multiple system atrophy
TLDR
This study proves that the accumulation of abnormal tubular structures in both oligodendrocytes and neurons is the basic pathological alteration in multiple system atrophy and defines multiple system atrocphy as a group of diseases with similar cellular pathology or as a nosological entity.
Cytoskeletal protein abnormalities in patients with olivopontocerebellar atrophy — an immunocytochemical and Gallyas silver impregnation study
TLDR
Findings indicate that the argyrophilia in the OPCA subjects closely correlates with PHF and tau immunoreactivities.
Multiple System Atrophy
TLDR
The aim of this review is to clarify issues in relation to GCIs in MSA, by defining their diagnostic and biological significance and by comparing them with other, more recently observed glial changes.
Argentophilic intracytoplasmic inclusions in multiple system atrophy
TLDR
It is suggested that the inclusion may be specific to OPCA and related disorders which include PAF and a useful marker to distinguish O PCA from other neurodegenerative diseases.
Structural and immunocytochemical features of olivopontocerebellar atrophy caused by the spinocerebellar ataxia type 1 (SCA-1) mutation define a unique phenotype
TLDR
The type and neuroanatomical distribution of structural lesions were similarly reproduced in all probands at the end stage of SCA-1, to the point that they appeared to constitute a unique phenotype.
Cellular pathology in multiple system atrophy
TLDR
Two degenerative processes might synergistically cause neuronal depletion in MSA, due to the filamentous aggregation of α‐synuclein in the neurons in several brain regions and the widespread occurrence of GCIs associated with oligodendroglia–myelin degeneration in the central nervous system.
Distribution of neuronal cytoplasmic inclusions in multiple system atrophy.
TLDR
It is indicated that NCIs represent a special neuronal alteration characteristic of MSA and support the theory that OPCA, SND and SDS represent manifestations of a single condition i.e. MSA.

Electron microscopic structure of the “inclusion bodies” in Pick's disease
TLDR
Examination of the ultrastructure of these ‘bodies’ offered the opportunity to elucidate the nature of this specific histological alteration in Pick’s disease, and the artefactual problems posed by electron-microscopic examination of formalin-fixed tissue, the rarity of this disease prompted us to accept such technical limitations.
[Striatonigral degeneration associated with olivopontocerebellar atrophy. Anatomo-clinical study of 3 cases. Nosologic discussion].
TLDR
These cases cannot therefore be considered as a pathological entity but as a particular form of degeneration affecting multiple systems, associated with evidence of olivopontocerebellar degeneration.
Pick's disease. A clinical and ultrastructural study.
TLDR
Brain biopsy was performed on a 61-year-old woman with a four-year history of progressive dementia and it is proposed that Pick cells are the result of retrograde or transsynaptic degeneration and that the neuron aggregates whatever fibrillar material it has and can make.
Multiple system atrophy with autonomic failure Clinical, histological and neurochemical observations on four cases
TLDR
Four cases of progressive autonomic failure are described, in all of which there were additional non-autonomic neurological abnormalities, including pyramidal, extra-pyramidal and cerebellar features, including profound depletion in dopamine and noradrenaline from brain regions which are normally rich in these catecholamines.
The striatonigral degenerations. Putaminal pigments and nosology.
TLDR
Three new cases of striato-nigral degeneration (SND) are presented and the presence of neuromelanin in the putamen suggests that the putaminal atrophy is the primary lesion in SND which is a true supranigral form of parkinsonism.
Orthostatic hypotension and nicotine sensitivity in a case of multiple system atrophy.
TLDR
Evidence is provided that the basic disease is a primary atrophy of a selection of neurones in the CNS, and the features of sympathetic failure, including orthostatic hypotension, are attributable to cell loss in the intermediolateral columns; nicotine sensitivity is associated with cerebellar system disorders, which are present in some cases of the Shy-Drager syndrome.

TLDR
After a critical analysis of the classifications in current use, it is concluded that that of Greenfield (1954) remains the most appropriate for familial OPCA and SOPCA.
Lateral horn cells in progressive autonomic failure
TLDR
It was found that all cases of autonomic failure had suffered severe cell loss; on average three quarters of their lateral horn cells were lost.
