The effects of caprine arthritis encephalitis virus (CAEV) infection on cytokine activity of caprine monocytes stimulated with Escherichia coli lipopolysaccharide (LPS) were examined. Compared with supernatants from LPS-stimulated monocytes of CAEV-negative goats, supernatants from CAEV-positive goats stimulated less proliferation of murine thymocytes in the MTT (3-(4,5-dimethylthiazol-2-yl)2,5-diphenyl tetrazolium bromide) assay, showed about 50% less IL-1 activity on the IL-1-dependent cell line LBRM-33 1 A-5, and showed about 200% more tumor necrosis factor (TNF) activity on the TNF-sensitive murine fibroblast cell line L-929. These results indicate that CAEV infection changes caprine monocyte cytokine responsivity.
