Galectin-9 ameliorates immune complex-induced arthritis by regulating Fc gamma R expression on macrophages

Galectin-9 up-regulated Fc gamma RIIb expression of mouse peritoneal macrophages in vitro but down-regulated Fc gamma RIII expression. Galectin-9-treated macrophages stimulated with immune complexes (IC) produced less TNFalpha and IL-1 beta but more IL-10 than PBS-treated macrophages. Macrophage enh...

520 |a Galectin-9 up-regulated Fc gamma RIIb expression of mouse peritoneal macrophages in vitro but down-regulated Fc gamma RIII expression. Galectin-9-treated macrophages stimulated with immune complexes (IC) produced less TNFalpha and IL-1 beta but more IL-10 than PBS-treated macrophages. Macrophage enhancing effects on IC-induced C5a and neutrophil chemotactic activity were also diminished for galectin-9-treated macrophages. In galectin-9-treated mice, the severity of IC-induced arthritis was reduced, as were pro-inflammatory cytokine levels in inflamed joints and serum C5a. Fc gamma RIIb expression of macrophages from galectin-9-treated mice was up-regulated, whereas Fc gamma RIII expression was down-regulated. Macrophages from galectin-9-treated mice produced less TNFalpha and IL-1 beta but more IL-10 than PBS-treated mice. Disease severity of galectin-9-transgenic mice was milder than wild-type mice, whereas that of galectin-9-deficient mice was exaggerated. Furthermore, macrophage Fc gamma RIIb expression in galectin-9-deficient mice was down-regulated, while Fc gamma RIII expression was up-regulated. These results suggest that galectin-9 suppresses IC-induced inflammation partly by regulating Fc gamma R expression on macrophages
