Abstract
1. Tumour necrosis factor receptor-associated factor 3 (TRAF3) is a key regulator of innate immunity and acquired immunity, and has a salient anti-viral role. 2. In this experiment, the duck TRAF3 (DuTRAF3) gene was cloned according to the Anas platyrhynchos TRAF3 sequence to explore its function. The TRAF3 open reading frame contains 1704 bp that encode a protein of 567 amino acids, which contain a RING finger domain, two zinc finger motifs, a coiled-coil region, and a MATH domain. 3. Reverse transcription-polymerase chain reaction showed that DuTRAF3 was expressed in all the examined tissues, with a comparatively higher expression in the spleen and brain tissues. 4. In HEK293T cells, DuTRAF3 overexpression resulted in a significantly increased NF-κB activity and interferon (IFN)-β promoter activation. 5. Following resiquimod (R848) and poly(I:C) stimulation of duck peripheral blood mononuclear cells (PBMCs), the expressions of TRAF3 and IFN-β were significantly upregulated; in addition, following R848 stimulation, the mRNA levels of IL-6, IL-8 and IL-10 were also significantly upregulated. After infection with the Newcastle Disease Virus LaSota vaccine strain, the mRNA levels of IL-6 and IL-10 were significantly upregulated, while that of TRAF3 was downregulated. 6. These results suggest that DuTRAF3 has an important role to play in innate antiviral immune responses.

Abstract
Tumor necrosis factor receptor-associated factor 3 (TRAF3) is a multifunctional regulator implicated in both bacterial defense and antiviral immunity. Here, a TRAF3 gene from the seawater fish sea perch, designated as LjTRAF3, was characterized. The full-length cDNA of LjTRAF3 was 2972 bp including a 5' untranslated region (UTR) of 243 bp, a 3'UTR of 941 bp and a putative open reading frame of 1608 bp encoding a putative protein of 536 amino acid. The deduced LjTRAF3 protein contained a RING finger, two zinc fingers, a coiled-coil, and a meprin and TRAF-C homology domain. Phylogenetic analysis showed that LjTRAF3 shared the closest genetic relationship with Larimichthys crocea TRAF3. Gene expression analyses suggested that LjTRAF3 mRNA was ubiquitously expressed in all the tissues tested, and was up-regulated post red spotted grouper nervous necrosis virus (RGNNV) infection in vivo and in vitro. Reporter gene assay showed that LjTRAF3 significantly activated zebrafish type I interferon (IFN) promoter in vitro. During RGNNV infection, ectopic expression of LjTRAF3 significantly reduced the RNA dependent RNA polymerase transcription of RGNNV, and enhanced the expression of RIG-I-like receptors (RLR), janus kinase-signal transducers and activators of transcription (JAK-STAT) signaling pathway related genes and IFN stimulated genes (ISGs), including ISG15, PKR, VIG and TRIM39. Taken together, our results suggested that LjTRAF3 might trigger the expression of various ISGs to counter RGNNV infection by regulating the RLR-induced IFN and JAK-STAT signaling pathways.

Abstract
Acute pancreatitis is a common threat to human health. Caerulin provokes severe inflammations, causing injuries to surrounding pancreatic cells. TNF receptor-associated factor 3 (TRAF3) is a highly versatile regulator of immune response. The current study aims to understand the potential effect of TRAF3 on caerulin-induced pro-inflammatory responses. In the primary-cultured mouse bone marrow-derived macrophages (BMDMs), caerulin induced TRAF3 protein stabilization, which formed a complex with mitogen-activated protein kinase kinase 3 (MKK3) to mediate downstream p38 activation. Lentiviral shRNA-mediated TRAF3 stable knockdown significantly attenuated caerulin-induced MKK3-p38 activation and production of several key pro-inflammatory cytokines, including interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) and IL-17. Remarkably, TRAF3 knockdown in caerulin-stimulated BMDMs also alleviated cytotoxicity to Panc02 and primary mouse pancreatic cells. Thus, TRAF3 is required for caerulin-induced p38 activation and macrophage-mediated pro-inflammatory responses. TRAF3 expression in macrophages could be a novel therapeutic target protein for the treatment of acute pancreatitis.

FISH & SHELLFISH IMMUNOLOGY 2017; 60:119-128. [PMID: 27876623 DOI: 10.1016/j.fsi.2016.11.047] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/06/2016] [Revised: 11/18/2016] [Accepted: 11/19/2016] [Indexed: 05/07/2023]
Abstract
RIG-I-like receptors (RLRs) can recognize viral RNA and initiate innate antiviral response. In earlier studies, we demonstrated that RLRs were implicated in the antiviral immunity against RGNNV in the seawater fish sea perch (Lateolabrax japonicus). However, potential regulators of RLRs-mediated signaling pathways involved in RGNNV infection remain unclear. In this study, a novel ribonucleoprotein PTB-binding 1 (Raver1) of sea perch (LjRAVER1) was identified for the first time. The cDNA of LjRAVER1 was 4066 bp in length and encoded a deduced polypeptide of 733 amino acids. Phylogenetic analysis revealed a closer affinity of LjRAVER1 with Larimichthys Crocea Raver1. LjRAVER1 mRNA was constitutively expressed in all 10 sampled tissues, and rapidly and significantly increased in vivo upon RGNNV infection. Time course analysis showed that LjRAVER1 transcripts were significantly increased both in vivo and in vitro after RGNNV infection. Viral infection and poly I:C treatment caused translocation of LjRAVER1 from the nucleus to the cytoplasm. Ectopic expression of LjRAVER1 increased the transcription level of several RLR signaling pathway related genes inducible by poly I:C treatment in vitro. Moreover, the viral gene transcription and virus production of RGNNV were significantly decreased in LjRAVER1 overexpressing cells. Luciferase reporter assays demonstrated that overexpression of LjRAVER1 significantly increased the promoter activity of zebrafish IFN1. Taken together, these findings indicated that LjRAVER1 might be an important component of RLR signaling pathway and involved in RLR pathway-mediated IFN response in sea perch.
