| Abstract |
Resident alveolar macrophages (AM) play an important immunomodulatory role via suppression of lymphocyte proliferation, and nitric oxide (NO) plays a crucial role in this immunosuppression of AM. Our previous report suggested that during ozone (O3)-induced lung inflammation, bronchoalveolar lavage fluid (BALF) inhibited AM-mediated immunosuppression and concanavalin A (Con A)-induced proliferation of lymph node cells (LNC) [E. Koike et al. (1998) Toxicol. Sci. 41, 217-223]. In these studies, we investigated the mechanisms of the inhibition of BALF from O3-exposed rats (O3-BALF). We investigated whether BALF might affect (1) the interferon-gamma (IFN-gamma) production by Con A-stimulated LNC and IFN-gamma-induced NO production by AM, and (2) the interleukin (IL)-2 production by Con A-stimulated LNC and IL-2-induced LNC proliferation. These results demonstrated that O3-BALF inhibited IFN-gamma production by Con A-stimulated LNC, IFN-gamma-induced NO production by AM, and IL-2-induced LNC proliferation. In addition, the major inhibitory factor against AM-mediated immunosuppression in O3-BALF may be a protein of greater than 10 kDa. |
