ResumenTitanium dioxide nanoparticles (TiO2 NPs) have been classified as possibly carcinogenic to humans and they are an important nanomaterial widely used in pharmaceutical and paint industries. Inhalation is one of the most important routes of exposure in occupational settings. Several experimental models have shown that oxidative stress and inflammation are key mediators of cell damage. In this regard, Nrf2 modulates cytoprotection against oxidative stress and inflammation, however, its role in inflammation induced by TiO2 NPs exposure has been less investigated. The aim of this work was to investigate the role of Nrf2 in the cytokines produced after 4 weeks of TiO2 NPs exposure (5 mg/kg/2 days/week) using wild-type and Nrf2 knockout C57bl6 mice. Results showed that Nrf2 protects against inflammation and oxidative damage induced by TiO2 NPs exposure, however, Nrf2 is a positive mediator in the expression of IFN-γ, TNF-α, and TGF-β in bronchial epithelium and alveolar space after 4 weeks of exposure. These results suggest that Nrf2 has a central role in up-regulation of cytokines released during inflammation induced by TiO2 NPs and those cytokines are needed to cope with histological alterations in lung tissue.
