Specific activation of embryonic IFNAR1 and endometrial IFNAR2 induced by embryonic IFNτ directs normal uterine fate for bovine early implantation. J Reprod Immunol 2022; 153:103677.

Abstract
Interferon-tau (IFNτ), as an antiluteolytic factor secreted by trophoderm during the pregnancy of ruminants, actually functions by activating the IFNτ receptor 1 (IFNAR1) and IFNτ receptor 2 (IFNAR2). However, it has not been clearly understood how IFNτ-IFNAR cascade regulation processes between the embryo and uterine epithelial cells in ruminants. In this study, we found the expression and location of IFNτ in the bovine blastocysts from different production sources. IFNτ, IFNAR1 and IFNAR2 were all located in the trophoblast cells of the blastocyst. However, the fluorescence intensity of IFNAR1 was consistent with that of IFNτ. Antagonizing the expressions of IFNAR1 and IFNAR2 in embryos and co-culture with endometrial epithelium cells (EECs) reduced the expressions of Integrin αv β3, WNT7A, and ISG15 in EECs. Knocking out IFNAR1 and IFNAR2 reduce the expressions of Integrin αv β3 and WNT7A in EECs, the deletion of IFNAR2 gene has a greater impact than that of IFNAR1 gene. IFNAR1-/IFNAR2+ and IFNAR1+/IFNAR2- EECs were co-cultured with IVF embryos, the expression of Integrin αv β3 was inhibited, and the inhibition of IFNAR1+/IFNAR2- was much stronger, and the expression of WNT7A was not inhibited. The expressions of Integrin αv β3 and WNT7A did not change significantly after IFNAR1-/IFNAR2+ and IFNAR1+/IFNAR2- co-culture with PA embryos. All of these results strongly suggest that specific activation of embryonic IFNAR1 and endometrial IFNAR2 induced by embryonic IFNτ directs normal uterine preparation for bovine early implantation.

[PMID: 35728283 DOI: 10.1016/j.bbrc.2022.06.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Accepted: 06/08/2022] [Indexed: 12/01/2022]
Abstract
BACKGROUND and Purpose: To investigate the biological role of interferon α/β receptor 2 (IFNAR2) in type 1 diabetes (T1D). METHODS First, IFNAR2 mRNA and protein expression levels in serum of T1D patients and healthy controls were detected by RT-qPCR and Western blot. For experimental studies, 80 male C57BL/6 mice were randomly divided into 4 groups with 20 mice in each group: the control group, the T1D group, the T1D + ad-con group and the T1D + ad-si-IFNAR2 group. The T1D mouse model was generated by multiple intraperitoneal injections of small doses of streptozotocin (STZ). Body weight and blood glucose levels were measured weekly until 6 weeks. After 6 weeks, all mice were sacrificed and the levels of insulin (Ins), tumor necrosis factor α (TNF-α), interleukin 4 (IL-4), IL-6, and type I interferon γ (IFN-γ), IFNAR2 protein expression, the number of dendritic cells (DCs), and changes in islet β cells were assessed. RESULTS IFNAR2 mRNA and protein expression levels in serum of T1D patients were significantly higher than those in healthy controls (P < 0.05). Furthermore, IFNAR2 protein expression, number of DCs, and IFNAR2 mRNA, blood glucose, TNF-α, and IFN-γ levels were significantly upregulated in T1D mice compared with the control group (P < 0.05), while weight, and Ins, IL-6, and IL-4 levels were decreased (P < 0.05). However, knockdown of IFNAR2 reversed these trends. There was no significant difference in markers between the T1D + ad-con group and the T1D group (P > 0.05). CONCLUSIONS Knockdown of IFNAR2 reduced the inflammatory response and improved islet function of T1D mice.

Abstract
The hepatitis C virus (HCV), an obligatory intracellular pathogen, highly depends on its host cells to propagate successfully. The HCV life cycle can be simply divided into several stages including viral entry, protein translation, RNA replication, viral assembly and release. Hundreds of cellular factors involved in the HCV life cycle have been identified over more than thirty years of research. Characterization of these cellular factors has provided extensive insight into HCV replication strategies. Some of these cellular factors are targets for anti-HCV therapies. In this review, we summarize the well-characterized and recently identified cellular factors functioning at each stage of the HCV life cycle.

Selective Targeting of Vascular Endothelial YAP Activity Blocks EndMT and Ameliorates Unilateral Ureteral Obstruction-Induced Kidney Fibrosis. ACS Pharmacol Transl Sci 2021; 4:1066-1074.

Abstract
Kidney fibrosis is accompanied by vascular dysfunction. Discovering new ways to ameliorate dysfunctional angiogenesis may bypass kidney fibrosis. YAP (Yes-associated protein) plays a multifaceted role during angiogenesis. Here, we found that selectively targeting YAP signaling in the endothelium ameliorates unilateral ureteral obstruction (UUO)-induced kidney fibrosis. Genetic deletion of Yap1, encoding YAP protein, in VE-cadherin+ endothelial cells inhibited endothelial-to-mesenchymal transition (EndMT) and dysfunctional angiogenesis and improved obstructive nephropathy and kidney fibrosis. Treatment with the systemic YAP inhibitor verteporfin worsened kidney fibrosis symptoms because of its lack of cell specificity. In an attempt to identify endothelial-specific YAP modulators, we found that G-protein-coupled receptor coagulation factor II receptor-like 1 (F2RL1) was highly expressed in vessels after UUO-induced kidney fibrosis. The F2RL1 peptide antagonist FSLLRY-NH2 selectively blocked YAP activity in endothelial cells and ameliorated kidney fibrosis. Thus, selective antagonization of endothelial YAP activity might bypass kidney fibrosis and provide new avenues for the design of antifibrotic therapies.
