Effect of intravenous silica on the course of Nocardia asteroides pneumonia. 1988

Infectious Disease Section, Veterans Administration Medical Center, Minneapolis, Minnesota 55417.

Silica, a known toxin of mononuclear phagocytes, was administered intravenously to mice during Nocardia asteroides pneumonia. Mice that received silica had a sevenfold decrease in the number of peripheral blood monocytes and developed more severe N. asteroides pneumonia than control mice. Lung histology in mice that received silica resembled that of mice with impaired cell-mediated immunity. These results are most consistent with the explanation that silica injures blood monocytes and impairs their contributions to pulmonary host defense.

D007111	Immunity, Cellular	Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.
