Effects of Mycoplasma pulmonis Infection and Exposure to Nitrogen Dioxide on Activities on Natural Killer Cells and Macrophages of the Mouse

Abstract

A marked enhancement was seen in activities of mouse splenic natural killer (NK) cells and macrophages one week after infection with Mycoplasma pulmonis (Mp) or exposure to nitrogen dioxide (NO₂) . Macrophage activity of the Mp-infected mouse showed further augmentation by exposure to NO₂ while NK activity of Mp-infected mice was not affected by NO₂-exposure.
