Particulate matter is an air pollutant composed of various components,and has adverse effects on the human body. Particulatematter is known to induce cell death by generating animbalance in the antioxidant system; however, the underlyingmechanism has not been elucidated. In the present study, wedemonstrated the cytotoxic effects of the size and compositionof particulate matter on small intestine cells. We found thatparticulate matter 2.5 (PM2.5) with extraction ion (EI) components(PM2.5 EI), is more cytotoxic than PM containing only polycyclicaromatic hydrocarbons (PAHs). Additionally, PM-inducedcell death is characteristic of ferroptosis, and includes ironaccumulation, lipid peroxidation, and reactive oxygen species(ROS) generation. Furthermore, ferroptosis inhibitor as liproxstatin-1and iron-chelator as deferiprone attenuated cell mortality, lipidperoxidation, iron accumulation, and ROS production after PM2.5EI treatment in human small intestinal cells. These results suggestthat PM2.5 EI may increase ferroptotic-cell death by ironaccumulation and ROS generation, and offer a potential therapeuticclue for inflammatory bowel diseases in human smallintestinal cells.
