TL;DR: Analysis of rodent brains with X‐ray fluorescence (XRF) microscopy combined with immunohistochemistry allowed us to demonstrate that local Cu concentrations are thousands of times higher in the glia of the subventricular zone (SVZ) than in other cells.

TL;DR: In this article, a new mechanism featuring Mn$^{\text{IV}}$=O formation in the S$3}$ state is proposed to explain the spectroscopic results.

On the nature of the Cu-rich aggregates in brain astrocytes.

TL;DR: XRF imaging of Au-labeled lysosomes and ubiquitin demonstrates a lack of co-localization with Cu-rich aggregates suggesting they are not involved in a degradation pathway, and overall data suggest that Cu in aggregates is bound by either metallothionein-3 or a yet unknown protein similar to metallothsionein.

TL;DR: It is proposed that O-O bond formation occurs prior to the transfer of the final (4th) electron from the Mn4Ca cluster to the oxidized tyrosine YZ residue, and suggests an evolutionary adaptation to avoid releasing of harmful peroxide species.

Copper accumulation in rodent brain astrocytes: A species difference.
TL;DR: Analysis of additional brain areas of hippocampus (HP) and rostral migratory stream (RMS) with detailed X-ray fluorescent imaging (XRF) analysis suggests that the rat model may have important advantages over the mouse model for the study of hippocampal aging and neurodegeneration.
