Abstract
A systematic and flexible immunoregulatory network is required to ensure the proper outcome of antiviral immune signaling and maintain homeostasis during viral infection. Tumor necrosis factor-α-induced protein 8-like 2 (TIPE2), a novel immunoregulatory protein, has been extensively studied in inflammatory response, apoptosis, and cancer. However, the function of TIPE2 in antiviral innate immunity is poorly clarified. In this study, we reported that the expression of TIPE2 declined at the early period and then climbed up in macrophages under RNA virus stimulation. Knockout of TIPE2 in the macrophages enhanced the antiviral capacity and facilitated type I interferon (IFN) signaling after RNA viral infection both in vitro and in vivo. Consistently, overexpression of TIPE2 inhibited the production of type I IFNs and pro-inflammatory cytokines, and thus promoted the viral infection. Moreover, TIPE2 restrained the activation of TBK1 and IRF3 in the retinoic acid inducible gene-I (RIG-I)-like receptors (RLR) signaling pathway by directly interacting with retinoic acid inducible gene-I (RIG-I). Taken together, our results suggested that TIPE2 suppresses the type I IFN response induced by RNA virus by targeting RIG-I and blocking the activation of downstream signaling. These findings will provide new insights to reveal the immunological function of TIPE2 and may help to develop new strategies for the clinical treatment of RNA viral infections.

Abstract
Term labour is associated with activation of inflammation which results in myometrial contractility, cervical ripening and decidual/membrane rupture. Serum amyloid A1 (SAA1) is an acute response protein, whose role and underlying regulatory mechanisms in human labour remain unknown. In this study, we found that the mRNA and protein expression of SAA1 in human myometrium at term was increased in labouring tissues compared to non-labouring tissues. In addition, the expression of SAA1 was significantly increased in human primary myometrial cells treated with the pro-inflammatory cytokines interleukin-1 beta (IL-1β) or tumour necrosis factor-alpha (TNF-α). Knockdown of SAA1 using siRNA (siSAA1) resulted in a significant reduction in the expression and secretion of pro-inflammatory cytokines (IL8, IL6), chemokines (CXCL5, CCL2), adhesion molecules (ICAM1, ICAM5) and contraction-associated factors (COX2, PGE2). Mechanistically, the effects of SAA1 were mediated through activation of the Yes-associated protein (YAP) pathway. There was a decrease in the protein expression of phosphorylated YAP (pYAP) after treatment of siSAA1-transfected human primary myometrial cells with IL-1β or TNF-α. Moreover, enhanced expression of YAP reversed the effect of siSAA1 on pro-labour mediators. In conclusion, these experiments demonstrated that SAA1 accelerates the inflammatory response associated with parturition by activating YAP pathway, which may be a novel understanding of the molecular mechanism of labour onset.
