The biological effects of subacute inhalation of diesel exhaust following addition of cerium oxide nanoparticles in atherosclerosis-prone mice

► CeO2 nanoparticles added to diesel decreases the number of particles in exhaust. ► Atherosclerosis is associated with exposure to standard diesel fuel in ApoE mice. ► CeO2 nanoparticles in diesel induce cytokines in the brain of mice.
