Yang H, Xiao T, Deng Y, Ding C, Zhang M, Li J, Lv Z. JunD functions as a transcription factor of IL-10 to regulate bacterial infectious inflammation in grass carp (Ctenopharyngodon idella). Int J Biol Macromol 2024; 258:129045. [PMID: 38159700 DOI: 10.1016/j.ijbiomac.2023.129045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 12/04/2023] [Accepted: 12/23/2023] [Indexed: 01/03/2024]
Abstract
IL-10 is a key anti-inflammatory mediator ensuring the protection of a host from excessive inflammation in response to pathogen infections, whose transcription or expression levels are tightly linked to the onset and progression of infectious diseases. An AP-1 family member called CiJunD was shown to be a transcription factor of IL-10 in grass carp (Ctenopharyngodon idella) in the current study. CiJunD protein harbored the conserved Jun and bZIP domains. Mutant experiments demonstrated that CiJunD bound to three specific sites on IL-10 promoter, i.e., 5'-ATTATTCATA-3', 5'-AGATGAGACATCT-3', and 5'-ATTATTCATC-3', mainly relying on the bZIP domain, and initiated IL-10 transcription. Expression data from the grass carp spleen infected by Aeromonas hydrophila and lipopolysaccharide (LPS) challenged spleen leukocytes indicated that the expressions of CiJunD and IL-10 were positively correlated, while the expression of pro-inflammatory cytokines, such as IL-1β, IL-6, IL-8, IFN-γ, and TNF-α, showed an overall downward trend when CiJunD and IL-10 peaked. The ability of CiJunD to down-regulate the production of pro-inflammatory cytokines and up-regulate the expression of IL-10, both with and without LPS stimulation, was confirmed by overexpression experiments. Meanwhile, the subcellular fractionation assay revealed that the nuclear translocation of CiJunD was significantly enhanced after the LPS challenge. Moreover, in vivo administration of grass carp with Oxamflatin, a potent agonist of JunD activity, could promote IL-10 but suppress the expression of pro-inflammatory cytokines. Intriguingly, tissue inflammation lesions and the survival rates of grass carp infected with A. hydrophila were also significantly improved by Oxamflatin administration. This work sheds light on the regulation mechanism by JunD of IL-10 expression and bacterial infectious inflammation for the first time, and it may present a viable method for preventing infectious diseases in fish by regulating IL-10 expression and inflammatory response.

Tankrathok A, Mahong B, Roytrakul S, Daduang S, Temsiripong Y, Klaynongsruang S, Jangpromma N. Proteomic analysis of crocodile white blood cells reveals insights into the mechanism of the innate immune system. Heliyon 2024; 10:e24583. [PMID: 38312682 PMCID: PMC10835162 DOI: 10.1016/j.heliyon.2024.e24583] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2023] [Revised: 01/10/2024] [Accepted: 01/10/2024] [Indexed: 02/06/2024] Open
Abstract
Crocodiles have a particularly powerful innate immune system because their blood contains high levels of antimicrobial peptides. They can survive injuries that would be fatal to other animals, and they are rarely afflicted with diseases. To better understand the crocodile's innate immune response, proteomic analysis was performed on the white blood cells (WBC) of an Aeromonas hydrophila-infected crocodile. Levels of WBC and red blood cells (RBC) rapidly increased within 1 h. In WBC, there were 109 up-regulated differentially expressed proteins (DEP) that were up-regulated. Fifty-nine DEPs dramatically increased expression from 1 h after inoculation, whereas 50 up-regulated DEPs rose after 24 h. The most abundant DEPs mainly had two biological functions, 1) gene expression regulators, for example, zinc finger proteins and histone H1 family, and 2) cell mechanical forces such as actin cytoskeleton proteins and microtubule-binding proteins. This finding illustrates the characteristic effective innate immune response mechanism of crocodiles that might occur via boosted transcription machinery proteins to accelerate cytoskeletal protein production for induction of phagocytosis, along with the increment of trafficking proteins to transport essential molecules for combating pathogens. The findings of this study provide new insights into the mechanisms of the crocodile's innate immune system.

Abstract
The bacterial fish pathogen Edwardsiella tarda causes heavy stock mortality, severely hampering fish production, resulting in great economic loss to the farming industry. The first biological barriers that confer immune protection against pathogen entry are the fish mucosal surfaces. The present study was undertaken to investigate the influence of E. tarda on certain enzymatic and non-enzymatic parameters in the skin mucous secretions of the fish Cirrhinus mrigala using spectrophotometry and zymography. Fish were randomly divided into three groups: control, vehicle control, and infected. A sublethal dose of E. tarda (2.2 × 106 CFU/fish) suspended in 50 μL of PBS was injected intra-peritoneally at 0 day (d). Subsequently, mucus samples were collected at 2 d, 4 d, 6 d and 8 d post-infection. The activities of lysozyme (LYZ), protease (PROT), alkaline phosphatase (ALP), acid phosphatase (ACP), catalase (CAT), peroxidase (PER), superoxide dismutase (SOD), and glutathione S-transferase (GST) decreased significantly in the skin mucus of the challenged fish, indicating the suppressed immune system and decreased antioxidant capacity of C. mrigala to E. tarda infection. Lipid peroxidation (LPO) and total nitrate-nitrite were significantly higher at several time points post-infection, suggesting that physiological functions have been impaired following pathogen challenge. The present findings could be relevant for fish aquaculture and underline the importance of skin mucus not only for assessing fish immune status but also for identifying early warning signals of disease caused by pathogens.

Abstract
The present study evaluated the pathogenicity, immunological, and oxidant/antioxidant responses against Saprolegnia parasitica (S. parasitica) infection in Nile tilapia (Oreochromis niloticus). Three groups of Nile tilapia were assigned as the control group (no zoospores exposure). The other two groups were challenged by Saprolegnia zoospores; one was used for sampling, and the other for mortality monitoring. The study lasted 3 weeks and was sampled at three point times at 1, 2, and 3 weeks. Results showed that S. parasitica zoospores were pathogenic to Nile tilapia, causing a cumulative mortality rate of 86.6%. Immunoglobulin M and C- reactive protein (IgM and CRP) levels showed a similar trend being significantly (P < 0.05, P < 0.001) higher in the infected group at weeks 1, 2, and 3, respectively, compared to the control group. Oxidant and antioxidant parameters in gills revealed that Malondialdehyde (MDA) level was significantly higher in the infected group compared to the control group. While catalase, glutathione peroxidase, and superoxide dismutase (CAT, GSH, and SOD) levels were significantly decreased in the infected group compared to the control group. Compared to the control, the tumor necrosis factor-α (TNF-α) gene was firmly upregulated in gill tissue at all-time points, particularly at day 14 post-infection. Meanwhile, Interleukin 1-β (IL-1 β) gene was significantly upregulated only at days 7 and 14 post-infection compared to control. Histopathological examination revealed destructive and degenerative changes in both skin and gills of experimentally infected Nile tilapia. Our findings suggest that Nile tilapia-S. parasitica infection model was successful in better understanding of pathogenicity and host (fish)-pathogen (oomycete) interactions, where the induced oxidative stress and upregulation of particular immune biomarkers in response to S. parasitica infection may play a crucial role in fish defense against oomycetes in fish.

Abstract
The present work was designed to assess the potential hemato-biochemical protective action, immunemodulatory and antioxidant conclusions of varied concentration of white mulberry Morus alba leaves (MAL) extract supplementation on Nile tilapia (Oreochromis .niloticus). A total two hundred and forty of O. niloticus were haphazardly sorted into four groups. The control (CT) group was fed on basal diet. A group MAL1, MAL3 and MAL5 was fed on 1, 3 and 5 g/kg MAL respectively for thirty days. On day thirty one, half of replicates in each group were challenged by 0.5 ml × 108Aeromonas hydrophila where, the residual replicates were kept without challenge. A. hydrophila challenged tilapias revealed anemia that alleviated by supplementation with 5 g/kg MAL also, recovers the shift of leucogram prompted by the challenge. Elevation of alkaline phosphatase, aminotransferases, lactate dehydrogenase and malondialdehyde (ALP, ALT, AST, LDH and MDA) in CT, MAL1 and MAL3 in the challenged replicates respectively where within normal at MAL5. Supplementation with MAL5 showed more potent antioxidant and immune reaction than MAL1 and MAL3. There were a rapid increase of immunoglobulin M, lysozymes, nitric oxide, catalase and superoxide dismutase and their allied genes expression (IgM, CAT and SOD) in MAL groups with contrast in CT challenged groups. Where in challenged groups, there was suppression in genes expression of interleukins (8 and 1 beta) and interferon ɤ (IL8. IL-1β and INFɤ). Tilapias challenged by A. hydrophila unveiled plentiful surge in the percentage of mortality in CT challenged fish (80%), followed by the groups supplemented with MAL1 and MAL3 were (73.33%) where MAL5 was 20%. The mortalities have been halted from the 6th, 13th, 14th and 15th days in, MAL5, MAL3, MAL1, and CT correspondingly. These previous results could be fulfilled that using of MAL 5 g/kg protect tilapias from hemato-biochemical alterations and enhance its immune feedback, antioxidant defense and resistance against A. hydrophila.

Abstract
Apoptosis-associated speck-like protein containing a caspase-recruitment domain (ASC) is a component of inflammasome, which plays crucial roles in the inflammatory response. In mammals, ASC regulates caspase-1 activation, thereby inducing pyroptosis and producing activated inflammatory cytokines. In addition, ASC also interacts with receptor-interacting protein kinase 2 (RIPK2) and induces nuclear factor-κB (NF-κB) activation. However, the role of ASC remains poorly understood in fish. In this study, we focused on elucidating the role of ASC in fish that were infected with Aeromonas hydrophila using Japanese medaka (Oryzias latipes) as fish model, and ASC-knockout (KO) medaka was established using CRISPR-Cas9 system. ASC-KO and wild type (WT) medakas were infected with A. hydrophila, and mortality was observed. ASC-KO medaka demonstrated higher mortality than WT. Moreover, the expression of immune-related genes in the kidney and intestine of the ASC-KO and WT medakas challenged with A. hydrophila were analyzed. Following A. hydrophila infection, the kidney of ASC-KO medaka exhibited significantly lower expression of NF-κB regulated genes (e.g., IL-1β, IL-6, IL-8 and TNF-α) and RIPK2 gene than in WT kidney. Moreover, to investigate the immune response against A. hydrophila via ASC in the medaka, bacterial burden, superoxide anion production, and lactate dehydrogenase release in the kidney cells of ASC-KO medaka were measured. After infection, these responses in ASC-KO medaka were significantly decreased compared to those in WT. These results suggest that the medaka ASC plays a critical role against A. hydrophila infection by inducing inflammatory responses and cell death for bacterial clearance.

Abstract
Complement is traditionally recognized as part of the innate immune system, defending the host against the invasion of foreign pathogens. In complement system, C3 (complement component 3) is a central component. Therefore, research into C3 can help us better understand the functions of fish complement system. In this study, we detected the grass carp C3 (gcC3) mRNA expression in all sample tissues from healthy grass carp, which was highest in the liver, followed by the heart and the spleen, and lowest in the muscle, head kidney, trunk kidney, blood and intestine. After infection with Aeromonas hydrophila, gcC3 mRNA expression levels were significantly upregulated in the gill, liver, spleen, intestine, trunk kidney and head kidney. Interestingly, C3 protein levels were downregulated and subsequently upregulated in the liver and serum. Histologically, C3 protein at 24 h pi was over expressed in necrotic liver sites, and the liver index (LI) at this point was significantly higher than that of the control. These findings are indicated that C3 plays an important role in the immune response of grass carp after A. hydrophila infection, and C3 protein may play an assistant role in repairing liver tissues from A. hydrophila injury.

Abstract
Outer membrane proteins (OMPs) play essential roles in antibiotic resistance, particularly in Gram-negative bacteria; however, they still have many unidentified functions regarding their behavior in response to antibiotic stress. In the current work, quantitative tandem mass tag labeling-based mass spectrometry was used to compare the outer membrane related proteins between an oxytetracycline-resistant (OXY-R) and its original control stain (OXY-O) in Aeromonas hydrophila. Consequently, a total of 261 commonly altered proteins in two biological repeats were identified including 29 proteins that increased and 28 that decreased. Gene ontology analysis showed that the expression of transport proteins was significantly reduced, and translation-related proteins were downregulated in the OXY-R strain. After using western blotting to validate selected altered proteins, eight OMP-related genes were knocked out and their roles in antibiotic resistance were further evaluated. The survival assays showed that some mutants such as ΔAHA_4281, ΔAHA_2766, ΔAHA_2282, ΔAHA_1181, and ΔAHA_1280 affected the susceptibility of A. hydrophila to antimicrobials. Moreover, the minimum inhibitory concentration assay showed that these candidate mutants also respond differently to other types of antibiotics. Our results reveal several novel outer membrane related proteins of A. hydrophila that play important roles in antibiotic resistance, and as such, may be helpful for screening studies to identify novel drug targets.

Abstract
In recent years, Aeromonas hydrophila, which has been classified as a food borne pathogen, has presented with increased levels of antibiotic resistance, with the mechanisms of this resistance being poorly understood. In this study, iTRAQ coupled mass spectrometry was employed to compare differentially expressed proteins in chlortetracycline (CTC) resistant A. hydrophila relative to a control strain. Result showed that a total of 234 differential proteins including 151 down-regulated and 83 up-regulated were identified in chlortetracycline resistance strain. Bioinformatics analysis showed that chemotaxis related proteins, such as CheA-2, CheR-3, CheW-2, EnvZ, PolA, FliS and FliG were down-regulated in addition to previously reported tricarboxylic acid cycle (TCA) related proteins also being down-regulated. A subset of identified differentially expressed proteins was then further validated via Western blotting. Exogenous metabolite combined with CTC further enhanced the bacterial susceptibilities to CTC in A. hydrophila. Furthermore, a bacterial survival capability assay showed that several chemotaxis related mutants, such as ΔcheR-3 and ΔAHA_0305, may affect the antimicrobial susceptibility of A. hydrophila. Overall, these findings contribute to a further understanding of the mechanism of CTC resistance in A. hydrophila and may contribute to the development of more effective future treatments. BIOLOGICAL SIGNIFICANCE A. hydrophila is a well-known fish pathogenic bacterium and has presented with increasing levels of antibiotic resistance, with the mechanisms of this resistance being poorly understood. Our current study compared the differentially expression proteins between chlortetracycline (CTC) resistant and control stains via an iTARQ-based quantitative proteomics method. Chemotaxis related proteins were down-regulated in CTC resistant strain but exogenous metabolite addition increased bacterial susceptibility in A.hydrophila. Significantly, chemotaxis related genes depletion affected antimicrobial susceptibilities of A.hydrophila indicating the role of chemotaxis process in antibiotics resistance.

Leaves from banana (Musa nana) and maize (Zea mays) have no phyto-prophylactic effects on the susceptibility of grass carp (Ctenopharyngodon idella) to Aeromonas hydrophila infection.

Abstract
Background The ubiquitous and opportunistic bacterial pathogen Aeromonas hydrophila has been associated with ulcerative dermatitis in fish, especially under stressful conditions. It can cause severe losses in fresh water aquaculture and is particularly prevalent in tropical and subtropical regions. Fresh leaves from maize and bananas have been used as feed supplement by fish farmers in Vietnam and it has been reported that they may have phyto-prophylactic benefits. In the present study, a feeding trial was conducted to investigate the benefits of providing maize and banana leaves as feed supplement: to determine if they were taken up and digested by grass carp (Ctenopharyngodon idella), if this uptake resulted in improved growth performance, and if leaf supplementation protected fish when challenged with A. hydrophila by intramuscular injection. Results All fish were fed an identical ratio of commercial pelleted feed relative to biomass. However, in 12/18 tanks, this diet was supplemented with either fresh banana leaves or fresh maize leaves; offered ad libitum. Addition of leaves increased the overall feed conversion ratio (FCR) significantly. However, if only the pellet were taken into account, then no difference was found between treatments. Changes to the isotopic composition of the fish showed leaf nutrient uptake occurred. No prophylactic effects of feeding banana or maize leaves were detected against infection with A. hydrophila, and the diet did not induce changes in the fish haematocrit. However, addition of the maize leaves was associated with significantly reduced severity of the skin lesions, which could improve the market value of the fish. Conclusions Addition of the leaf supplement did not result in significantly improved growth performance. Similarly, the effect of the supplement on the fish survival to infection was not significant.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2017; 76:93-104. [PMID: 28559111 DOI: 10.1016/j.dci.2017.05.019] [Citation(s) in RCA: 42] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/03/2017] [Revised: 05/24/2017] [Accepted: 05/24/2017] [Indexed: 06/07/2023]
Abstract
Pattern recognition receptors (PRRs) play indispensable roles in the immune responses against invading pathogens. In the present study, we systematically identified and characterized Toll-like receptors (TLRs), retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) as well as their adaptors in grass carp (Ctenopharyngodon idella). A comprehensive analysis of BLAST and other bioinformatics methods showed that C. idella TLR family consist of 21 members and their adaptors contain four members. Phylogenetic analyses confirmed the existence of six TLR subfamilies (TLR1, 3, 4, 5, 7 and 11 subfamily) in C. idella and revealed their homologous relationships with other species. Most C. idella TLRs possess three typical structural features of TLR protein family: LRR, TM and TIR domains. Meanwhile, RLR family consist of three conserved members (RIG-I, MDA5 and LGP2) as well as two adaptors (IPS-1 and STING) in C. idella. mRNA expression analyses of TLRs, RLRs and their adaptors indicated that most members are sustainably expressed in multiple tissues before and after grass carp reovirus (GCRV) or Aeromonas hydrophila infection, while TLR9, TLR20a/b, TLR25, TIRAP, SARM1 and STING are transiently expressed in specific tissues. TLRs are transmembrane receptors with few introns, while RLRs are cytoplasmic receptors with plenty of introns. TLRs and RLRs interact with adaptors to perform their functions via various signaling pathways. In conclusion, this study systematically explores the characteristics of TLRs and RLRs in C. idella and provides evidence for the response patterns after viral and/or bacterial infection in vivo. These results contribute to studying the regulation mechanisms of TLR and RLR signaling pathways, and deeply understanding fish immune responses against pathogen infection.

Abstract
Intensive aquaculture has increased the susceptibility of fish to Aeromonas hydrophila, and this has led to severe economic damage. There has been little study of the host defense mechanism against A. hydrophila infection in scaleless fish. Therefore, in the present study, the transcriptome profiles of the spleen of Pelteobagrus vachellii were examined after infection with A. hydrophila. In total, 37,730 unigenes from 322 KEGG pathways were identified. Following A. hydrophila infection, 27,803 differentially expressed genes were identified, including 13,934 upregulated and 13,869 downregulated genes. Significant enrichment analysis of these differentially expressed unigenes showed that the major immune pathways were involved, including toll-like receptor pathways, B-cell receptor signaling pathways, Fcγ receptor-mediated phagocytosis, complement and coagulation cascades, and natural killer cell-mediated cytotoxicity pathways. From these pathways, 59 key immune-related differentially expressed genes were selected: 53 genes that were upregulated, including those coding for complement components, interferons, and interleukins, and six DEGs that were downregulated, including inhibitor of nuclear factor kappa-B kinase. Finally, nine DEGs, which were randomly selected, were confirmed by qRT-PCR to be differentially expressed. The results indicated that complement components, interferons and Fcγ receptor-mediated phagocytosis played key role in the response to A. hydrophila infection in the spleen of P. vachellii, which may prove useful in the future for the development of therapeutic regimens.
