چکیده انگلیسی
Various parasites modify the immune-reactions of the host. We have previously shown that crude excretory/secretory (ES) products from plerocercoids of Spirometra erinaceieuropaei, the plerocercoids of which cause sparganosis in humans, suppress the expression of tumor necrosis factor (TNF)-α and IL-1β in lipopolysaccharide (LPS)-stimulated macrophages. As osteoclasts are cells of the monocyte/macrophage lineage, we hypothesised that ES products might suppress receptor activator of nuclear factor κB ligand-induced osteoclastogenesis. Crude ES products from plerocercoids suppressed osteoclastogenesis, judged by tartrate-resistant acid phosphatase (TRAP)-positive multinuclear cell counting, and the mature osteoclast-specific gene expression (calcitonin receptor and TRAP). Second, we purified the inhibitory factor for osteoclastogenesis from the crude ES products. The factor was a trypsin-sensitive glycoprotein and had a relative molecular mass of 90 kDa. The glycoprotein, plerocercoid-immunosuppressive factor, from crude ES products could suppress the gene expression of TNF-α, IL-1β and NO synthesis in LPS-stimulated RAW264.7 macrophages.
