Another report by Zhang and collaborators also highlighted glial activation and production of reactive oxygen species in response to oligomer-like preparations of aggregated a-syn [168]. PubMed:28803412
Neurons from these animals exhibited increased oxidative stress, increased generation of ROS, DNA fragmentation, neuronal apoptosis, and impairment in learning, compared to single-transgenic mAPP mice. PubMed:30444369
In another study, neurons from Tg mAPP/ABAD mice were shown to exhibit decreased activity of cyclooxygenase (COX) enzyme, spontaneous release of ROS, loss of mitochondrial membrane potential, a decrease in ATP production and release of cytochrome c from mitochondria with subsequent induction of caspase-3-like activity followed by apoptotic cell death. PubMed:30444369
Dysfunctional mitochondria are critically harmful to cells, as this leads to decreased synthesis of cellular ATP and accumulation of ROS, which further overburden and damage other functional mitochondria. PubMed:29758300
Excessive amounts of free radicals and radical-derived reactive species may also arise from the activity of NAD(P)H oxidases (NOx) and/or xanthine oxidase, as well as from nitric oxide synthase (NOS), P450 metabolism and peroxisomes. PubMed:24563850
Excessive amounts of ROS may also arise from inflammatory processes [75]. PubMed:24563850

We indeed found that there is an overexpression (w15%) of Nox1 protein (a component of NADPH oxidase complex) by Western blot, suggesting the role of NADPH oxidase complex as a potential source of ROS PubMed:28528849
These findings suggest that the ROS production induced by extracellular TauRDΔK oligomers might cause the activation of NADPH oxidase complex PubMed:28528849
By contrast, monomers of TauRDΔK even at 10 mM concentration did not cause any significant ROS increase (Fig. 5B). PubMed:28528849
We observed an oligomer-dependent increase in the ROS production in the mature rat primary hippocampal neurons in all cellular compartments (Fig. 5A). PubMed:28528849

The mitochondrial membrane potential, ROS and NO levels were down-regulated by 1,8-cineole in A 25-35-stimulated cells [250]. PubMed:29179999
The phosphorylation of the NF-B inflamma-tory pathway in A 25-35-stimulated microglial cells was inhibited by vitamin D2 via reducing ROS and inflammatory cytokines [207] PubMed:29179999
Glaucocalyxin B, found in Rabdosia japonica, considerably atten-uated the expression of NO, TNF-, IL-1, COX-2 and iNOS in LPS-induced microglia cells [169–172]. Moreover, the activation of NF-B, p38 MAPK and ROS generation was interrupted by glauco- calyxin B in LPS-induced microglia cells [172]. PubMed:29179999
Besides, it significantly decreased the generation of ROS and affected LPS-induced activation of MAPK, including p38 and NF-B signaling[243]. PubMed:29179999
Higher levels of ROS biomarkers are characteristic of AD patients in clinical and preclinical studies, resulting in the alteration of membrane proper- ties, such as fluidity, ion transport, enzyme activities, protein cross- linking, tau protein hyperphosphorylation, autophagic dysfunction and eventually neuron cell death [20].

Excessive accumulation of Aβ1-42 stimulates microglial cells by signaling via receptor associated advanced glycation end products (RAGE) and peroxisome proliferator-activated receptor-γ (PPAR-γ), phosphorylates IKK proteins, and enhances NF-κB mediated transactivation of inflammatory cytokines and neurotoxic molecules such as glutamate and reactive oxygen species (ROS)/induced nitric oxide synthase (iNOS) [12] (Fig 2B) PubMed:25652642
Furthermore NF-κB specific inhibitor prevents iNOS and ROS upregulation in Aβ stimulated cultures of astrocytes or mixed cortical cells PubMed:25652642
Beyond METH, redox-related changes that result from an imbalance between reactive oxygen species (ROS) production and ROS clearance are implicated in schizophrenia PubMed:30061532
This channel senses intracellular ROS and responds by opening itself to facilitate Ca2+ influx into the cell; this is intriguing considering that both ion fluxes and the oxidative state (see below) have important roles in NLRP3 inflammasome activation. PubMed:23702978
In particular, ROS facilitate the assembly of the apoptosome in several ways. PubMed:23702978
Specifically, ROS have been shown to regulate a wide variety of signalling pathways including anti- inflammatory responses and adaptation to hypoxia [77,78], autop- hagy [79], immune cell function [80], cellular differentiation [81], integrins [82], as well as oncogenes signalling [83].

Under different envi- ronmental conditions such as Aβ/ROS/cytokines accumulation, the IκB kinase (IKK) complex becomes activated and mediates the phosphoryla- tion of IκBs, then IκBs are degradated and the remaining NF-κB dimer is activated and thus translocates to the nucleus where it binds to the DNA consensus sequence of various target genes [9–11].

ROS has been found not only the regulators of NF-κB, interestingly, iNOS is also regulated by NF-κB. PubMed:27288790
ROS generation leads to phosphorylation of NF-κB cytoplasmic inhibitor IκBα. NF-κB is thus liberated and transports to the nucleus. PubMed:27288790
