They found that the mutant mice had significantly higher
endosome acidity.
The mutant mice with the higher
endosome acidity also had more degradation of a receptor protein, called TrkB, that responds a neurotrophic factor called BDNF.

Using lab - grown mouse astrocytes with variant forms of NHE9, the researchers found a change in the pH (
acidity) inside cellular compartments called
endosomes, which in turn altered the ability of cells to take up glutamate.
Sometimes
acidity in the
endosome can activate protein - degrading enzymes called proteases.
In their experiments the researchers measured
acidity in the
endosomes of brain cells of normal mice and in mice with mutations in the NHE6 gene.
