Effects of NMN supplementation on systemic responses upon subacute and sub-chronic PM exposure. Legends Systemic effects about the inflammatory and oxidative responses in mice upon subacute and sub-chronic PM exposure were examined by measuring the plasma levels of (A) IL-6, (B) TNF-α, and (C) MDA. The results were presented as mean ± SEM. *P < 0.05; **P < 0.01; ***P < 0.001. Con-H2O: air-filtered control group administered drinking water; Con-NMN: air-filtered control group supplemented with NMN; PM-H2O: PM exposed group administered drinking water; PM-NMN: PM exposed group with NMN supplementation
