Summary: In this study, the virulence-related gene ORF71L of Infectious spleen and kidney necrosis virus (ISKNV) was identified. Deletion of ORF71L resulted in decreased viral replication rate, reduced virulence, and lower mortality in mandarin fish. Additionally, deletion of ORF71L also led to an increase in the number of melanomacrophage centers in the spleen of infected fish.

Summary: In this study, the transcription factor c-Myc was found to play a critical role in virus replication by regulating glutamine metabolism. The cloned Sc-c-Myc in mandarin fish tissues showed high homology with other species. Overexpression of Sc-c-Myc promoted ISKNV and SCRV replication while knocking it down restrained their replication, indicating it could be a potential target for new therapeutic strategies.

Summary: In fish, IL-6 and IL-6ST play important roles in immune response, and their expression is upregulated after ISKNV infection in mandarin fish. A SNP locus in the coding region of IL-6 is significantly associated with ISKNV resistance, suggesting the potential of using SNP markers in breeding for disease resistance.

Summary: TiO2 nanoparticles were synthesized using Echinophora cinerea extract, and their toxicity on zebra fish was evaluated. The optimal synthesis conditions were found to be pH 9, extract concentration 20 g/L, TiO2 concentration 0.4 g/L, and temperature 25 degrees Celsius. The bioassay results showed that the LC50 of green synthesized TiO2 NPs with Echinophora cinerea extract was 300 mg/L, indicating a less hazardous material.

Summary: APOBEC3A (A3A) can suppress gene expression by binding specific DNA sequences, affecting the expression of genes involved in antiviral responses and type I IFN signaling. Additionally, A3A impacts IFN-I induced gene expression by inhibiting a specific signaling pathway. This study reveals an unexpected role of A3A in the IFN signaling pathway.

Summary: In this study, a continuous cell line called SCC was established from spinal cord tissue of mandarin fish. SCC cells showed susceptibility to ISKNV, SCRaV, and SCRV, and could stably produce and transmit these viruses.

Summary: The spotted knifejaw (Oplegnathus punctatus) is an emerging economical aquaculture species in China. In this study, an iridovirus-like disease outbreak (SKIV-SD) in the spotted knifejaw aquaculture industry in Shandong Province was characterized. The SKIV-SD virus, identified as an ISKNV-type megalocytivirus, caused severe mortality and pathological lesions in cultured spotted knifejaw, sharing genetic similarities with infectious spleen and kidney necrosis virus (ISKNV).

Summary: This study successfully produced and characterized monoclonal antibodies (mAbs) against Mandarinfish ranavirus (MRV). Seven mAbs that specifically recognized MRV/LMBV were obtained through Western blotting screening and they targeted late expression structural proteins of MRV. The tissue tropism of MRV was re-assessed using immuno-histochemistry and immuno-histo-fluorescence, and it was found that spleen, kidney, intestines, and pyloric caecum are the major target tissues. Infected intestines and pyloric caecum showed enlarged, multinucleated cells with intracytoplasmic inclusions as the target cells of MRV.

Summary: Circular RNAs (circRNA) are involved in gene expression and affect cellular processes such as transcription, splicing, and translation by interacting with microRNA and RNA binding proteins. A study identified circDNAJB6 as a circular RNA abundant in chicken macrophages after bacterial infection, and found that circDNAJB6 exacerbates cellular injury and interacts with multiple miRNAs and target genes, potentially impacting autophagy and MAPK signaling pathways.

Summary: The innate immune response relies on the ability of host cells to detect and respond to microbial nucleic acids. Toll-like receptors (TLRs) play a crucial role in this process by distinguishing self from non-self. This study focused on TLR21, an avian TLR that recognizes bacterial DNA motifs. The findings suggest that avian TLR21 shares similar activation mechanisms to mammalian TLR9, highlighting the conservation of nucleic acid sensing mechanisms across species.

Summary: Chickens have a unique immune structure characterized by the absence of draining lymph nodes and the presence of well-developed mucosa-associated lymphoid tissue. The structure and development of chicken lymphoid tissues in the intestine, particularly Peyer's patches, have been poorly studied. However, the use of CSF1R-eGFP reporter transgenic chickens has allowed for the visualization and investigation of the development and distribution of these tissues. This research provides insights that could benefit mucosal vaccination strategies and the development of targeted vaccine delivery systems.
