abstract = {This study leverages X-ray phase-contrast tomography for
detailed analysis of neurodegenerative diseases focusing on
the 3D visualization and quantification of neuropathological
features within fixed human postmortem tissue. X-ray
phase-contrast tomography with synchrotron radiation offers
micrometer and even sub-micron resolution, enabling us to
examine intra- and extraneuronal aggregates and inclusions
such as Lewy bodies, granulovacuolar degeneration, Hirano
bodies, neurofibrillary tangles, β-amyloid plaques and
vascular amyloid deposits in three dimensions (3D). In the
reconstructions, we identified the highest electron
densities in Hirano bodies and Lewy bodies while
neurofibrillary tangles exhibit only slight alterations in
X-ray phase-contrast tomography contrast. Using cutting edge
high-resolution X-ray synchrotron beamlines we are now able
to even detect subcellular differences of electron densities
found in granulovacuolar degeneration. Small scale
inhomogeneities of the electron density are also detected in
Lewy bodies potentially relating to inclusions of
organelles. Additionally, we reveal a peculiar 3D geometry
of Hirano bodies and demonstrate the co-occurence with
granulovacuolar degeneration in the same neuron. Utilizing
X-ray phase-contrast tomography in a complementary fashion
to traditional technologies, a quantitative, systematic and
disease-overarching understanding of inclusions and
aggregates in neurodegeneration can be achieved.},
