Moreover,
LPS- or IL-2-stimulation

Gao et al., FASEB J 2003
(Nerve Degeneration...) :
Mechanistically, microglial NADPH oxidase mediated generation of reactive oxygen species played a pivotal role in the synergistic neurotoxicity : MPTP and

stimulated the
NADPH oxidase mediated release of superoxide free radical ; pharmacological inhibition and genetic inactivation of NADPH oxidase prevented superoxide production and the synergistic neurotoxicity

LPS induced MyD88 dependent activation of Rac2,
NADPH oxidase , and ROI production using mice deficient in Vav1, Vav2, and Vav3
Pacquelet et al., Biochem J 2007

IRAK-4 phosphorylated p47phox activated the NADPH oxidase in a cell-free system, and IRAK-4 overexpression increased
NADPH oxidase activity in
response to
LPS
Lin et al., J Agric Food Chem 2007
:
LPS increased the expression of TLR4 in HASMCs, and this effect was
mediated by the activation of nicotinamide adenine dinucleotide phosphate (
NADPH ) oxidase , phosphorylation of intracellular mitogen activated protein kinases ( MAPKs ), and increases in the cytoplasmic level of HuR and TLR4 mRNA stability ... G. biloba extract inhibited LPS induced HASMC proliferation and decreased the expression of TLR4 by inhibiting
LPS induced
NADPH oxidase activation, mRNA stabilization, and MAPK signaling pathways
Deng et al., Zhonghua Xin Xue Guan Bing Za Zhi 2007
:
NOx production by 10 ( -7 ) mol/L and 10 ( -6 ) mol/L ALD increased by 50.0 % and 58.7 % respectively ( P < 0.01 ) and iNOS activity was also significantly increased ( P < 0.01 ) in ALD + RU486 group than that in ALD group. ( 2 )
LPS significantly
increased the
NOx production and iNOS activity ( P < 0.01 ) and these effects were not augmented by adding ALD to LPS ( P > 0.05 ) and SP significantly blocked and RU486 significantly enhanced the effects by LSP and ALD on NOx production and iNOS activity ( P < 0.05 )

Moreover, we demonstrate that TGF-beta1 inhibited
LPS induced
NADPH oxidase ( PHOX ) subunit p47phox translocation from the cytosol to the membrane in microglia within 10 min. Mechanistic studies show that TGF-beta1 fails to protect dopaminergic neurons in cultures from PHOX knockout mice, and significantly reduced LPS induced translocation of the PHOX cytosolic subunit p47phox to the cell membrane
