Certain particle compounds may directly generate ROS in vivo because of their surface chemistry (eg, metals, organic compounds, and semiquinones) or after bioactivation by cytochrome P450 systems (eg, polycyclic aromatic hydrocarbon conversion to quinones).6, 290 a, 290 b A particle surface or anions present on otherwise more inert particles may disrupt iron homeostasis in the lung and thereby also generate ROS via Fenton reactions.291 Other PM constituents may do so indirectly by the upregulation of endogenous cellular sources (eg, nicotinamide adenine dinucleotide phosphate [NADPH]-RRB- oxidase) 292,293 or by perturbing organelle function (eg, mitochondria) by taken - up PM components.261 Particle stimulation of irritant and afferent ANS fibers may also play a role in local and systemic oxidative stress formation.294 Given the rich antioxidant defenses in the lung fluid, secondarily generated oxidization products of endogenous molecules (eg, oxidized phospholipids, proteins) or a reduction in endogenous antioxidants per se may be responsible at least in part for the state of oxidative stress in the lungs (along with instigating the subsequent cellular responses) rather than ROS derived directly from PM and its constituents.

Aβ is believed to penetrate neuronal plasma membranes, where it leads to lipid peroxidation.10 It has also been implicated in deactivating a subunit of the pyruvate dehydrogenase complex, thereby inhibiting conversion of pyruvate to acetyl CoA and the eventual production of cellular energy as ATP.32 Another way Aβ affects glucose metabolism in the brain is that fragments of Aβ disrupt insulin signaling by binding to neuronal synapses, which alters their shape and function.15, 38 Insulin receptors are abundant at synapses, so if the integrity of the synapse itself has been compromised, the receptors won't function effectively.
