    Abstract Background: Dementia with Lewy bodies (DLB) is one of the major neurodegenerative diseases and a clinical diagnosis is made based on the fourth consensus report on DLB. However, clinicopathological features of DLB are variable among cases.
    Methods: We analyzed three autopsy-proven cases of DLB (patients 1-3). Their clinical features were variable in spite of their pathological commonality. The entire hemispheric sections were stained for phosphorylated alpha-synuclein (aS), digitized, and each aS positive lesion was mapped using a virtual slide system.
    Results: The three patients were clinically diagnosed as having DLB. However, patient 1 exhibited amnesia and misrecognition, while patient 3 exhibited abnormal behavior in addition to dementia. Therefore, both patients 1 and 3 did not fulfill the clinical criteria of DLB, in contrast to patient 2. In spite of the clinical heterogeneity, Lewy pathology was similar in patients 1, 2, and 3. Additionally, patient 1 exhibited less frequent Lewy neurites of the amygdala and entorhinal cortex, and less frequent neurofibrillary tangles and senile plaque as compared to patient 2. On the other hand, the Lewy pathology of patient 3 extended far beyond those of patients 1 and 2, wherein the superior to middle frontal cortices, insular cortex, and lentiform nucleus were severely affected by Lewy pathology.
    Conclusions: Clinical features could be variable among autopsy-proven cases of DLB. Furthermore, we show that the accent of Lewy pathology differs according to the variability of the clinical symptoms. This method will provide a comprehensive strategy to analyze wide-spread aS lesions scattered throughout the entire cerebral hemisphere and help determine the corresponding pathological lesions responsible for the clinical variability of neurodegenerative disorders, including DLB.

    Abstract Cadmium selenide quantum dots (QDs) are fluorescent and electron-dense nanoparticles. When used as reporter of immunolabeling, this dual visibility is essential for direct comparison of its fluorescent signals on light microscopy (LM) and their ultrastructrual counterparts on electron microscopy (EM) as correlative light and electron microscopy (CLEM). To facilitate EM recognition, QDs on EM grid were gold enhanced, which increased their size and electron density. On histological sections as well, gold-enhanced QDs, used as a reporter of immunolabeling, were easily recognized on EM. Because target structures are visible on bright field microscopy, gold enhancement facilitated trimming the target structures into final EM sections. Furthermore, gold enhancement of rod-shaped QD655 on EM grid was accentuated on their tips while spherical QD565 was gold-enhanced as sphere in contrast. This EM distinction was evident on histological sections where QD565 (green fluorescence) and QD655 (red fluorescence) were used as a reporter pair for double immunolabeling. Double-labeled immuno-fluorescent images, initially captured before EM processing, are now compared with their respective immuno EM counterparts. Specific labeling of each epitope was corroborated by mutual comparison between LM and EM. Although fluoronanogold may be a candidate reporter partner with QDs for gold-enhanced, double-labeling CLEM, its limited penetration into fixed tissue hampers universal use for thick histological sections. Gold-enhancement of QD immunolabeling, now expanded to double-labeling CLEM for human brain samples, will pave the way to translate molecular events into ultrastructural morphopathogenesis in situ.

    Abstract The immune system plays an important role in protection against infection and cancer, and in the maintenance of the internal environment of the body. However, such important immune functions are known to decline with age in many mammals, including humans. It is a matter of clinical importance that the incidence of various age-associated diseases such as infections, cancer, and vascular disorders increases with a decrease in immunological vigor. The extent of immunologic decline is variable and exhibits wide interindividual variations. Thus, it is important to assess the extent of immunologic decline in both patients suffering from various diseases and in healthy people in order to maintain healthy conditions. To this end, we have developed a scoring system that analyzes immune parameters according to a database of known age-associated immune changes obtained from a healthy population. Using this scoring system, we can combine several different immunological parameters and express the immune status of individuals as a simple numeral. Several methods of immunological restoration were introduced and the magnitude of restoration was evaluated by the quantitative assessment of immunological level.

    Abstract Background: Spinocerebellar ataxia type 31 (SCA31) is not usually associated with dementia, and autopsy in a patient with both conditions is very rare.
    Case presentation: An 87-year-old male patient presented with ataxia and progressive dementia. Genetic testing led to a diagnosis of SCA31. Fifteen years after his initial symptoms of hearing loss and difficulty walking, he died of aspiration pneumonia. A pathological analysis showed cerebellar degeneration consistent with SCA31 and abundant argyrophilic grains in the hippocampal formation and amygdala that could explain his dementia.
    Conclusions: This is the first autopsy report on comorbid argyrophilic grain disease with SCA31.
