Primary cortical neurons exposed to the mitochondrial toxin NaN3 (0.1-3 mM) were submitted to oxidative stress with H2O2 (30-150 μM), to mimic conditions observed in neurodegenerative disorders. The effects of such treatment on a series of parameters useful in characterizing neuronal damage were investigated: (i) the basal release of glutamate, evaluated as (3)H-d-Aspartate efflux, was sharply, concentration-dependently, increased; (ii) the phosphorylation status of intracellular markers known to be involved in the neurodegenerative processes, in particular in Alzheimer disease: tau and GSK3β were increased, as well as the protein level of β-secretase (BACE1) and p35/25 evaluated by Western blotting, while (iii) the cell metabolic activity, measured with the MTT method, was reduced, in a concentration- and time-dependent manner. The latter effect, as well as tau hyperphosphorylation, was prevented both by a mixture of antioxidant drugs (100 μM ascorbic acid, 10 μM trolox, 100 μM glutathione) and by the anti-Alzheimer drug, memantine, 20 μM.

As shown in Figure 3, the level of heme degradation is highly correlated with the level of metHb in RBCs (R = 0.6233, p < 0.0177) supporting the hypothesis that the heme degradation product formed in PRDX2 knockout mice is associated with the un-scavenged H2O2 generated during Hb autoxidation.

However, metHb levels may increase when there is an increase in Hb autoxidation and the concomitant generation of H2O2 that is not scavenged by antioxidant defense enzymes making it more difficult for metHb-reductase to keep up with the metHb produced. PubMed:23215741

Peroxiredoxin-2 (Prx-2) has emerged as the critical antioxidant protecting RBCs from H2O2 produced endogenously (by Hb autoxidation and subsequent superoxide dismutation) and exogenously (e.g., from activated neutrophils) at low (physiologic) concentrations (11, 32, 38, 40, 43, 45) and, therefore, may limit oxidative injury to other cells/tissues in the vasculature (6, 57).

The finding that GPx has a greater role in the inhibition of heme degradation products than catalase [3] is consistent with the primary role of catalase to react with the high concentrations of H2O2 coming from exogenous sources and for GPx to react with the low levels of H2O2 coming from the endogenous autoxidation of Hb [39].
