Abstract
Niemann-Pick disease type C (NPC) is a neurovisceral lipid-storage disease. Although NPC patients show lipid storage in anterior horn cells of the spinal cord, little information is available regarding the electron microscopic analyses of the morphologies of intra-endosomal lipid like-materials in the anterior horn cells of NPC patients. In this study, we elucidated the intra-endosomal ultrastructures in spinal anterior horn cells in an NPC patient, as well as in mutant BALB/c NPC1-/- mice with a retroposon insertion in the NPC1 gene. These morphologies were classified into four types: vesicle, multiple concentric sphere (MCS), membrane, and rose flower. The percentages of the composition in the NPC patient and NPC1-/- mice were: vesicle (55.5% and 14.9%), MCS (15.7% and 3.4%), membrane (23.6% and 57.1%), and rose flower (5.2% and 24.6%), respectively. Formation of the intra-endosomal structures could proceed as follows: (i) a vesicle or MCS buds off the endosome into the lumen; (ii) when a vesicle breaks down, a membrane is formed; and (iii) after an MCS breaks down, a rose flower structure is formed. Our new finding in this study is that ultrastructural morphology is the same between the NPC patient and NPC1-/- mice, although there are differences in the composition.

Abstract
Background We aimed to produce a detailed neuropathological analysis of pyramidal motor system pathology and provide its clinical pathological correlation in cases with definite progressive supranuclear palsy (PSP). Methods Pyramidal motor system pathologies were analyzed in 18 cases with neuropathologically confirmed PSP. Based on a retrospective clinical analysis, cases were subtyped according to Movement Disorder Society criteria for clinical diagnosis of PSP as probable, possible or suggestive of PSP with Richardson’s syndrome (n = 10), PSP with predominant corticobasal syndrome (n = 3), PSP with predominant parkinsonism (n = 3), PSP with predominant speech/language disorder (n = 1), and PSP with progressive gait freezing (n = 1). Clinical manifestations of motor neuron involvement (pseudobulbar or bulbar signs and spasticity) were retrospectively assessed semiquantitatively. Neuropathologically, hyperphosphorylated tau-related pyramidal motor system neuronal, neuritic, and glial pathology using anti-tau AT8 clone immunohistochemistry, was also evaluated. Results Clinical manifestations of pyramidal motor system involvement were found in patients with different PSP subtypes. A statistically significant higher load of tau pathology was found in the pyramidal system in PSP-Richardson’s syndrome compared to other PSP subtypes (p = 0.016); however, there was no significant correlation between pyramidal system tau pathology and related motor clinical symptoms. Conclusions Tau pathology in the spinal cord and pyramidal motor system structures is very common in progressive supranuclear palsy and may neuropathologically supplement the distinction between classic Richardson’s syndrome from other progressive supranuclear palsy subtypes.

Abstract
We describe the histopathologic features of spinal cord lesions in 10 cases of progressive supranuclear palsy (PSP) and review the literature. Histologic examination revealed atrophy with myelin pallor in the anterior funiculus and anterolateral funiculus in the cervical and thoracic segments in eight of the 10 cases, whereas the posterior funiculus was well preserved. The degrees of atrophy of the anterior funiculus and the anterolateral funiculus correlated with that of the tegmentum of the medulla oblongata. Myelin pallor of the lateral corticospinal tract was observed in two of the 10 cases. Microscopic observation of the spinal white matter, particularly the cervical segment, revealed a few to several neuropil threads, particularly in the white matter surrounding the anterior horn after Gallyas-Braak (GB) staining or AT-8 tau immunostaining. However, the posterior funiculus was completely preserved from the presence of argyrophilic or tau-positive structures. In the spinal gray matter, widespread distribution of neurons with cytoplasmic inclusions and neuropil threads was observed, particularly in the medial division of the anterior horn and intermediate gray matter, especially in the cervical segment. Globose-type neurofibrillary tangles and pretangles were found. The distribution of GB- or AT-8 tau-positive small neurons and neuropil threads resembled that of the spinal interneurons. In conclusion, the spinal cord, especially the cervical segment, is constantly involved in the pathologic process of PSP. We speculate that spinal interneurons and their neuronal processes, particularly in the medial division of the anterior horn and intermediate gray matter of the cervical segment, are most severely damaged in the PSP spinal cord.
