Abstract
Ficus hirta Vahl. (FhV) has been shown to have antimicrobial and antiviral efficacy. To further ascertain the pharmacological properties of FhV., and to search for alternatives to antibiotics. An in vitro experiment was carried out to evaluate what influence FhV. would have on LPS-induced apoptosis. In this study, Fas, an apoptosis receptor, was cloned, which included a 5'-UTR of 39 bp, an ORF of 951 bp, a protein of 316 amino acids, and a 3'-UTR of 845 bp. EcFas was most strongly expressed in the spleen tissue of orange-spotted groupers. In addition, the apoptosis of fish spleen cells induced by LPS was concentration-dependent. Interestingly, appropriate concentrations of FhV. alleviated LPS-induced apoptosis. Inhibition of miR-411 further decreased the inhibitory effect of Fas on apoptosis, which reduced Bcl-2 expression and mitochondrial membrane potential, enhanced the protein expression of Bax and Fas. More importantly, the FhV. could activate miR-411 to improve this effect. In addition, luciferase reporter assays showed that miR-411 binds to Fas 3'-UTR to inhibit Fas expression. These findings provide evidence that FhV. alleviates LPS-induced apoptosis by activating miR-411 to inhibit Fas expression and, therefore, provided possible strategies for bacterial infections in fish.

Cao M, Wang N, Yan X, Yang N, Fu Q, Zhang X, Zhang Y, Li C. Structures, evolutionary relationships and expression profiles of the tumour necrosis factor superfamily and their receptors in black rockfish (Sebastes schlegelii). DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2022; 132:104405. [PMID: 35364135 DOI: 10.1016/j.dci.2022.104405] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Revised: 03/25/2022] [Accepted: 03/25/2022] [Indexed: 06/14/2023]
Abstract
Members of tumour necrosis factor superfamily (TNFSF) and TNF receptor superfamily (TNFRSF) have crucial roles in many important biological processes such as cell proliferation, cell death, development, survival, immunity, and various diseases. The human TNFSF consists of 19 ligands and 29 receptors. Compared with those in human, fish have most of the TNFSF and receptors that have been found in mammals, while some of the homologues are specific or lost in fish. Especially, no systematic report on the identification of TNFSF ligands and their receptors in S. schlegelii. Therefore, to investigate the characterization and molecular evolution of TNFSF and TNFRSF genes in Sebastes schlegelii, we performed a genome-wide survey and identified 14 TNFSFs and 24 TNFRSFs from S. schlegelii. In S. schlegelii, we found duplication events occurred in TNFSF2, TNFSF6, TNFSF10, TNFSF13, TNFSF14, TNFRSF5, TNFRSF6, TNFRSF6B, TNFRSF10B, TNFRSF16, and TNFRSF19 genes. Among which, the tandem duplications events occurred in TNFSF13 and TNFRSF6, and the whole genome duplications events occurred in the remaining TNFSF and TNFRSF genes. Based on the molecular phylogenetic analysis, 14 TNFSFs were divided into three different clusters and 24 TNFRSFs were classed as three distinct subgroups, respectively. Meanwhile, protein domains and motifs analysis revealed that TNFSF contain homology domain (THD), and TNFRSF have typical cysteine-rich domains (CRDs). Synteny results indicates that the TNFSFs and TNFRSFs neighborhood genes have taken place great changes compared to those in human, fugu and zebrafish. Meanwhile, qRT-PCR results demonstrated that most TNFSFs and TNFSRSFs were significantly differentially expressed in gill, skin and intestine after E. tarda infection with time-dependent manners. In addition, protein-protein interaction network (PPI) analysis indicated that the most related genes connecting to TNFSF and TNFRSFs were TNFSF ligands and receptors. In summary, this study provided a new understanding for characterization and evolution of the TNFSF genes and their receptors in S. schlegelii.

The effect of intermittent hypoxia under different temperature on the immunomodulation in Streptococcus agalactiae vaccinated Nile tilapia (Oreochromis niloticus). FISH & SHELLFISH IMMUNOLOGY 2018; 79:181-192.

Abstract
Dissolved oxygen (DO) and temperature are the potential immunomodulators in fish and play the important roles in regulating immunity. We studied the effect of intermittent hypoxia under different temperature on the immunomodulation in vaccinated Nile tilapia (Oreochromis niloticus). The expression of immune-related genes, enzymatic activities, histology, cumulative mortality, and S. agalactiae clearance were assessed. Study conditions were intermittently hypoxic (4.0 ± 1.0 mg/L DO) at 30 ± 0.5 °C or 35 ± 0.5 °C. Interleukin-1beta (IL-1β), tumor necrosis factor alpha (TNF-α) and gamma interferon (IFN-γ) mRNA expression in spleen and head kidney were significantly lower in vaccinated hypoxic fish compared to the vaccinated normoxic fish. Levels of heat shock protein 70 (HSP70) in tissues showed an opposite tendency. Superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) activities were significantly lower in vaccinated hypoxic fish. Malondialdehyde levels were significantly greater under hypoxic conditions. In vitro studies evaluated the effects of intermittent hypoxia at different temperatures on cells of vaccinated O. niloticus. Phagocytic activity of peripheral blood leucocytes (PBLs) and intracellular reactive oxygen species (ROS) production in head kidney cells were significantly decreased by intermittent hypoxia at either 30 °C or 35 °C, while nitric oxide levels in tissues cells increased significantly under hypoxic conditions. These changes were well reflected by the further suppression modulation on S. agalactiae clearance in vaccinated O. niloticus and higher cumulative mortality by intermittent hypoxia. Taken together, intermittent hypoxia at either 30 °C or 35 °C could suppress immunomodulation in vaccinated Nile tilapia.

Purinergic system displays an anti-inflammatory profile in serum of silver catfish experimentally infected with Streptococcus agalactiae: An attempt to ameliorate the inflammatory response. Microb Pathog 2017; 114:193-196.

Abstract
The purinergic system is recognized to modulate extracellular adenosine triphosphate (ATP) and related nucleotides through the activities of triphosphate diphosphohydrolase (NTPDase), 5'-nucleotidase, and adenosine deaminase (ADA), thereby playing an essential role in the immunoregulation of inflammatory and immune responses. Thus, the aim of this study was to evaluate whether the purinergic system can improve the inflammatory response in fish experimentally infected with Streptococcus agalactiae through the modulation of seric NTPDase, 5'-nucleotidase and ADA activities. Seric NTPDase (ATP as substrate) and 5'-nucleotidase activities increased in silver catfish experimentally infected with S. agalactiae compared with the uninfected control group, while seric ADA activity decreased. Based on this evidence, our findings suggest that regulation of adenine nucleotide hydrolysis occurs in an attempt to restrict the inflammatory process and improve the immune system by hydrolyzing excess extracellular ATP. On the other hand, downregulation of seric ADA activity may be an attempt to augment extracellular adenosine (a molecule with anti-inflammatory effects) levels. In summary, the purinergic system is capable of modulating the immune and inflammatory responses during fish streptococcosis.

Abstract
Xanthine oxidase (XO) is a final enzyme of purine metabolism linked with initiation and progression of infectious diseases, since is considered an important source of reactive oxygen species (ROS) and nitric oxide (NO), developing a pro-oxidant and pro-inflammatory profile in some infectious diseases. Thus, the aim of this study was to evaluate the involvement of XO activity in the renal oxidative and inflammatory damage, as well as the interplay with ROS and metabolites of nitric oxide (NOx) levels in silver catfish experimentally infected with Streptococcus agalactiae. Xanthine oxidase activity, and uric acid, ROS and NOx levels increased in renal tissue of infected animals compared to uninfected animals. Moreover, the histopathological analyses revealed the presence of necrosis, generalized edema and nuclear degeneration of renal tubules. Based on these evidences, the upregulation on renal XO activity exerts a pro-oxidant and pro-inflammatory profile in kidney of fish infected with S. agalactiae. The excessive uric acid levels induced the release of oxidative and inflammatory mediators, such as ROS and NOx, that directly contribute to renal oxidative and inflammatory damage. In summary, the upregulation on XO activity may be considered a pathway involved in the renal injury during S. agalactiae infection.
