Therefore, significant molecular changes during the pre-symptomatic phase caused by TrkB signalling depletion may induce iSPN vulnerability

Our work provides an understanding of how age-associated cognitive decline in older humans is linked to glutathione deficiency, increased oxidative stress, mitochondrial dysfunction, abnormal glucose metabolism and insulin resistance, inflammation and low levels of neurotrophic or neuron-supporting factors, and that supplementing GlyNAC reverses these defects and improves cognition. Human studies only permit measurements at the whole-body level, so in this study the researchers studied mice to investigate defects directly in the aging brain
In particular, the copper residue in glutathione is less than 1 ppm: copper is present in undetectable amounts, in both the amorphous solid and the crystalline solid
