PG - 170-2 LID - S0034-5288(16)30072-8 [pii] LID - 10.1016/j.rvsc.2016.04.004 [doi] AB - The giant panda (Ailuropoda melanoleuca) is an endangered species. Interleukin-18 (IL-18) plays an important role in the innate and adaptive immune responses by inducing IFN-gamma. IL-18 has been implicated in the pathogenesis of various diseases. IL-18 binding protein (IL-18BP) is an intrinsic inhibitor of IL-18 that possesses higher affinity to IL-18. In this study, we cloned and characterized IL-18BP in giant panda (AmIL-18BP) from the spleen. The amino acid sequence of giant panda IL-18BP ORF shared about 65% identities with other species. To evaluate the effects of AmIL-18BP on the immune responses, we expressed the recombinant AmIL-18BP in Escherichia coli BL21 (DE3).The fusing protein PET-AmIL-18BP was purified by nickel affinity column chromatography. The biological function of purified PET-AmIL-18BP was determined on mice splenocyte by qRT-PCR. The results showed that AmIL-18BP was functional and could significantly reduce IFN-gamma production in murine splenocytes. These results will facilitate the study of protecting giant panda on etiology and immunology. CI - Copyright (c) 2016 Elsevier Ltd. All rights reserved.
