“↑” increase, “↓“ decrease, “nc” no change, “blank” data not available,
compared to nPM alone; NAC (N-acetyl L-cysteine). We propose a hierarchy of nPM effects, with lower dose inducing increases NO as first effect, but still below the threshold of oxidative stress required for changes in protein levels and increased production of Aβ peptides.
