Parasitic Helminth Cystatin Inhibits DSS-Induced Intestinal Inflammation Via IL-10+F4/80+Macrophage Recruitment
Open accessAbstract
Many immune down-regulatory molecules have been isolated from parasites, including cystatin (cystain protease inhibitor). In a previous study, we isolated and characterized Type I cystatin (CsStefin-1) of the liver fluke, Clonorchis sinensis. To investigate whether the CsStefin-1 might be a new host immune modulator, we induced intestinal inflammation in mice by dextran sodium sulfate (DSS) and treated them with recombinant CsStefin-1 (rCsStefin-1). The disease activity index (DAI) increased in DSS only-treated mice. In contrast, the DAI value was significantly reduced in rCsStefin-1-treated mice than DSS only-treated mice. In addition, the colon length of DSS only-treated mice was shorter than that of rCsStefin-1 treated mice. The secretion levels of IFN-γ and TNF-α in the spleen and mesenteric lymph nodes (MLNs) were significantly increased by DSS treatment, but the level of TNF-α in MLNs was significantly decreased by rCsStefin-1 treatment. IL-10 production in both spleen and MLNs was significantly increased, and IL-10(+)F4/80(+) macrophage cells were significantly increased in the spleen and MLNs of rCsStefin-1 treated mice after DSS treatment. In conclusion, rCsStefin-1 could reduce the intestinal inflammation occurring after DSS treatment, these effects might be related with recruitment of IL-10 secreting macrophages.

Helminth cystatins from S. japonicum, Ascaris lumbricoides, and Clonorchis sinensis all ameliorate colitis in vivo.
“Other helminth cystatins with broad immunomodulatory properties including those from S. japonicum (Wang et al., 2016), Ascaris lumbricoides, and the liver fluke Clonorchis sinensis all ameliorate colitis in vivo”
From Modulation of Host Immunity by Helminths: The Expanding Repertoire of Parasite Effector Molecules (2018) · cites this paper as Jang et al., 2011
The Results section reports that recombinant CsStefin-1 from Clonorchis sinensis reduced disease activity and tissue damage in mice with DSS-induced colitis. Our copy does not report that cystatins from Ascaris lumbricoides or S. japonicum ameliorate colitis in vivo; the citing sentence separately cites Wang et al. (2016) for S. japonicum.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
