abstract = {The clinical progression of neurodegenerative diseases
correlates with the spread of proteinopathy in the brain.
The current understanding of the mechanism of proteinopathy
spread is far from complete. Here, we propose that
inflammation is fundamental to proteinopathy spread. A
sequence variant of α-synuclein (V40G) was much less
capable of fibril formation than wild-type α-synuclein
(WT-syn) and, when mixed with WT-syn, interfered with its
fibrillation. However, when V40G was injected
intracerebrally into mice, it induced aggregate spreading
even more effectively than WT-syn. Aggregate spreading was
preceded by sustained microgliosis and inflammatory
responses, which were more robust with V40G than with
WT-syn. Oral administration of an anti-inflammatory agent
suppressed aggregate spreading, inflammation, and behavioral
deficits in mice. Furthermore, exposure of cells to
inflammatory cytokines increased the cell-to-cell
propagation of α-synuclein. These results suggest that the
inflammatory microenvironment is the major driver of the
spread of synucleinopathy in the brain.},
