Nrf2 Activator RTA-408 Protects Against Ozone-Induced Acute Asthma Exacerbation by Suppressing ROS and γδT17 Cells.
Ozone is a strong oxidant in air pollution that exacerbates respiratory disorders and is a major risk factor for acute asthma exacerbation. Ozone can induce reactive oxygen species (ROS) and airway neutrophilic inflammation. In addition, γδT17 cells contribute to IL-17A production upon ozone challenge, resulting in neutrophilic inflammation. It is known, however, that Nrf2 can ameliorate oxidative stress. We therefore investigated whether RTA-408, an Nrf2 activator, can attenuate airway inflammation and inhibit ROS production and whether this effect involves γδT17 cells. Balb/c mice were sensitized/challenged with ovalbumin (OVA) and followed by ozone exposure. We investigated the effect of Nrf2 activator RTA-408 on airway hyperresponsiveness, neutrophilic airway inflammation, cytokine/chemokine production, and OVA-specific IgE level in a mouse model of O3 induced asthma exacerbation. Furthermore, malondialdehyde (MDA) and glutathione (GSH) levels in lung and intracellular ROS were measured.
