炎症小体 NLRP6 在调节炎症和宿主防御肠道微生物方面发挥着至关重要的作用。然而,抑制 NLRP6 功能以防止过度炎症的分子机制仍不清楚。在这里,我们证明去泛素酶 Cyld 通过去泛素化 NLRP6 来防止结肠粘膜中白细胞介素 18 (IL-18) 的过量产生。我们发现去泛素化抑制 NLRP6-ASC 炎性体复合物并调节 IL-18 的成熟。小鼠中的 Cyld 缺陷导致活性 IL-18 水平升高,并在啮齿类柠檬酸杆菌感染后出现严重的结肠炎症。此外,在溃疡性结肠炎患者中,活性IL-18的浓度与CYLD表达呈负相关。因此,我们发现了一种抑制肠道炎症中 NLRP6-IL-18 通路的新调节机制。
The inflammasome NLRP6 plays a crucial role in regulating inflammation and host defense against microorganisms in the intestine. However, the molecular mechanisms by which NLRP6 function is inhibited to prevent excessive inflammation remain unclear. Here, we demonstrate that the deubiquitinase Cyld prevents excessive interleukin 18 (IL-18) production in the colonic mucosa by deubiquitinating NLRP6. We show that deubiquitination inhibited the NLRP6–ASC inflammasome complex and regulated the maturation of IL-18. Cyld deficiency in mice resulted in elevated levels of active IL-18 and severe colonic inflammation following Citrobacter rodentium infection. Further, in patients with ulcerative colitis, the concentration of active IL-18 was inversely correlated with CYLD expression. Thus, we have identified a novel regulatory mechanism that inhibits the NLRP6-IL-18 pathway in intestinal inflammation.
