Abstract
This study aimed to investigate the effects of dietary Bacillus subtilis supplementation on gut microbiota diversity, digestive enzyme activity, and Toll-like receptor (TLR) expression in broiler chickens. A total of 240 "817" crossbred broiler chickens were randomly assigned to four groups: control (basal diet, BD), group I (BD + 300 g/d B. subtilis at 1.08 × 107 CFU/kg), group II (BD + 600 g/d B. subtilis at 2.16 × 107 CFU/kg), and group III (BD + 900 g/d B. subtilis at 3.24 × 107 CFU/kg). Gut microbiota analysis revealed significant improvements in the abundance of specific microorganisms in the treatment groups, with distinct variations in the core microorganisms between the groups. Notably, protease activity in the ileum was significantly increased in groups II (22.59%; p < 0.01) and III (14.49%; p < 0.05) compared to that in the control group. Moreover, significant up-regulation of TLR1A and TLR7 expression was observed in jejunum and cecum of the treated groups. Additionally, the TLR1B expression in the ileum was significantly increased. Furthermore, TLR2A and MyD88 transcription levels were significantly elevated in the jejunum, liver, spleen, and kidneys of experimental groups. Modulations in the expression of various TLR's (TLR2B, TLR3, TLR4, TLR15, and TLR21) were also observed in different organs. The spleen and kidney of B. subtilis-supplemented chickens exhibited upregulated expression of the proinflammatory cytokine IL-1β. Dietary supplementation with B. subtilis in broiler chickens improved the gut microbiota diversity and significantly upregulated TLR's expression in various organs. B. subtilis could be a valuable feed additive, contributing to improved disease management and overall health in broiler chickens.

Selenium nanoparticles promotes intestinal development in broilers by inhibiting intestinal inflammation and NLRP3 signaling pathway compared with other selenium sources. Poult Sci 2024; 103:103958. [PMID: 38945002 PMCID: PMC11261441 DOI: 10.1016/j.psj.2024.103958] [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: 02/22/2024] [Revised: 05/25/2024] [Accepted: 06/04/2024] [Indexed: 07/02/2024] Open
Abstract
This study aimed to investigate how various selenium sources affect the intestinal health of broiler chickens. A total of 384, one-day-old Arbor Acres broilers were weighed and randomly allocated to four treatment groups. The control diet was a basal diet added with: 0.2 mg/kg Sodium Selenite (SS-control), 0.2 mg/kg Selenium nano-particles (Nano-Se), 0.2 mg/kg Selenomethionine (SeMet), and 0.2 mg/kg Selenocysteine (Sec) as the treatments. The results indicated that Nano-Se and SeMet were effective in enhancing the villus height (VH) and the villus height/crypt depth ratio (VH/CD) in the jejunum compared to (SS) (P < 0.05). The inclusion of Nano-Se into the diets increased the mRNA levels of zonula occluden-1 (ZO-1), ZO-2, Occludin, Claudin-1, and Claudin-3 compared to the SS diet (P < 0.05). The SeMet increased the levels of ZO-1 and Claudin-3 compared to the SS (P < 0.05). Moreover, SeMet upregulated the marker genes of intestinal enteroendocrine cells, stem cells, and epithelial cells compared to the SS diet (P < 0.05). However, supplementation of Nano-Se reduced the mRNA levels of interleukin 1β (IL-1β), and IL-8 and the concentration of reactive oxygen species (ROS) in the jejunum compared to the SS (P < 0.05). The Nano-Se and SeMet also increased the protein levels of CAT and SOD compared to the SS and Sec diet (P < 0.05). The number of the goblet cells and Mucin-2 (Muc2) levels were the highest in the Nano-Se group (P < 0.05). The protein expression levels of goblet cell differentiation regulator (v-myc avian myelocytomatosis viral oncogene homolog, c-Myc) were highest in the Nano-Se compared to the SS diet (P < 0.05). The Nano-Se decreased the mRNA and protein levels of NLRP3 signaling pathway-related genes compared to the SS diet (P < 0.05). In conclusion, our study demonstrated that Nano-Se and SeMet are better at improving the intestinal health of 21-day-old broilers. Additionally, Nano-Se demonstrated superior antioxidant and anti-inflammatory effects, promoting the development of intestinal goblet cells by modifying the NLRP3 signaling pathway.

Viruses 2022; 15:111. [PMID: 36680150 PMCID: PMC9866435 DOI: 10.3390/v15010111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 12/25/2022] [Accepted: 12/28/2022] [Indexed: 01/03/2023] Open
Abstract
Novel duck reovirus (NDRV) is a newly identified reovirus that brings about more severe damage on multiple organs and mortality in various species of waterfowl. We previously characterized the transcriptomic profiles responding to NDRV in the bursa of Fabricius of Muscovy ducklings, which is a major immunological organ against virus infection. However, the molecular mechanisms of variant cell responses in the bursa of Fabricius to NDRV with different virulence is unclear. Here, we conducted a whole transcriptomic analysis to study the effects of two strains, HN10 (virulent NDRV) and JDm10 (artificially attenuated NDRV), on the bursa of Fabricius of Muscovy ducklings. We harvested a large number of differentially expressed genes (DEGs) of the bursa of Fabricius specially induced by HN10 and JDm10, and we found that HN10 induced DEGs enriched in differentiation and development in multiple organs beyond JDm10. Moreover, the ceRNA regulatory network also indicated the different connections among mRNA, lncRNA and miRNA. Interestingly, we further noticed that a population of differential expressed miRNA could particularly target to transcripts of HN10 and JDm10. We took miR-24 as an example and observed that miR-24 could reduce the transcription of GLI family zinc finger 3 (Gli3) and membrane-associated guanylate kinase, WW and PDZ domain containing 1 (Magi1) via recognition 3' UTR of these two genes by a dual luciferase reporter gene assay in vitro. However, this effect could be compromised by HN10 infection or the ectopic over-expression of the putative miR-24 targeting regions in L1 and L3 fragments of HN10. Taken together, we examined and proposed a novel regulatory competitive mechanism between transcripts of NDRV and Muscovy ducklings for miRNA. These findings may advance the understanding of the molecular pathogenesis of NDRV in Muscovy ducklings, and help provide the potential targets for vaccine and drug development against NDRV.

Abstract
Selenium deficiency can affect the level of selenoprotein in organs and tissues and cause inflammation. However, the mechanism of selenium deficiency on jejunal injury in chickens remains unclear. In this study, we established a selenium deficiency model in chickens by feeding a low selenium diet and observed ultrastructural and pathological changes in the jejunum. The expression levels of 25 selenoproteins, the levels of oxidative stress, tight junction (TJ) proteins, and antimicrobial peptides (AMP), as well as the expression levels of factors related to inflammatory signaling pathways, were examined in the intestine and analyzed using principal component analysis (PCA). The results of PCA and quantitative real-time PCR (qRT-PCR) showed that selenium deficiency mainly affected the expression of antioxidant selenoproteins in chicken jejunum, especially glutathione peroxidases, thioredoxin reductase, and iodothyronine deiodinase, thus weakening the antioxidant function in the intestine and inducing oxidative stress. We also found disruption of intestinal TJ structures, a significant reduction in TJ protein expression, and downregulation of antimicrobial peptide levels, suggesting that selenium deficiency led to damage of the intestinal barrier. In addition, a significant increase in inflammatory cell infiltration and expression of inflammatory factors was observed in the jejunum, indicating that selenium deficiency induces inflammatory injury. In conclusion, selenium deficiency downregulates antioxidant selenoproteins levels, induces oxidative stress, decreases intestinal AMP levels, and leads to inflammatory injury and disruption of the intestinal barrier in the jejunum. These results shed new light on the molecular mechanisms of intestinal damage caused by selenium deficiency.

Abstract
To explore the role of ChTLR4/MyD88/NF-κB signaling pathway on autophagy induced by selenium (Se) deficiency in the chicken bursa of Fabricius, autophagosome formation in the bursa of Fabricius was observed by transmission electron microscopy. Quantitative real-time PCR (qRT-PCR) and Western blot were used to detect the expression of ChTLR4 and its signaling pathway molecules (MyD88, TRIF, and NF-κB), inflammatory factors (IL-1β, IL-8, and TNF-α), and autophagy-related factors (ATG5, Beclin1, and LC3-II) in the Se-deficient chicken bursa of Fabricius at different ages. The results showed that ChTLR4/MyD88/NF-κB signaling pathway was activated in the chicken bursa of Fabricius and autophagy was induced at the same time by Se deficiency. In order to verify the relationship between the autophagy and ChTLR4/MyD88/NF-κB signaling pathway, HD11 cells were used to establish the normal C group, low Se group, and low Se + TLR4 inhibitor (TAK242) group. The results demonstrated that autophagy could be hindered when the TLR4 signaling pathway was inhibited under Se deficiency. Furthermore, autophagy double-labeled adenovirus was utilized to verify the integrity of autophagy flow induced by Se deficiency in HD11 cells. The results showed that it appeared to form a complete autophagy flow under the condition of Se deficiency and could be blocked by TAK242. In summary, we found that Se deficiency was involved in the chicken bursa of Fabricius autophagy occurring by activating the ChTLR4/MyD88/NF-κB pathway.

Abstract
Selenium (Se) is an essential trace element found in the body. Se deficiency and M1/M2 imbalance are closely related to inflammation. Heat stress can decrease immune function and cause inflammation. In order to investigate whether Se deficiency can aggravate pneumonia caused by heat stress and the role of M1/M2 imbalance in the occurrence of pneumonia, 100 AA broilers were divided into two groups and fed the conventional diet (0.2 mg/kg Se) and the Se-deficient diet (0.03 mg/kg Se). After 40 days of feeding, the normal feeding group was randomly divided into a control group and a heat stress group. At the same time, the Se-deficient diet feeding group was randomly divided into a low Se group and a low Se heat stress group, with 25 chickens in each group. The model was established by exposure at 40℃. Six hours later, broilers were euthanized, and their lung tissues were collected. Hematoxylin and eosin staining, immunofluorescence, quantitative real-time PCR, and western blotting were used to detect lung histopathological changes and the expression of M1/M2 markers, nuclear receptor-κB (NF-κB) pathway genes, and heat shock proteins. Meanwhile, the activity and content of oxidative stress-related indices were also detected. We found that the expression of interleukin-1β, interleukin-6, interleukin-12, and tumor necrosis factor-α was upregulated and the expression of interleukin-2, interleukin-10, and interferon-γ was downregulated. Immunofluorescence showed that the expression of CD16 was increased, the expression of CD163 was weakened, and the M1/M2 imbalance was present. In addition, the NF-κB pathway was activated by the increased expressions of heat shock proteins and oxidative stress. There was an increase in malondialdehyde, nitric oxide, and inducible nitric oxide synthase content, while the activity of total antioxidant capacity, glutathione peroxidase, catalase, and superoxide dismutase decreased, and the expression of NF-κB and cyclooxygenase-2 increased. These results suggest that low Se induces M1/M2 imbalance through oxidative stress activation of the NF-κB pathway and aggravates lung tissue inflammation caused by heat stress. This study offers a theoretical basis for exploring the pathogenesis of various kinds of inflammation induced by Se deficiency from the perspective of M1/M2 and provides a reference for the prevention of such diseases.

Selenium-enriched Polysaccharide: an Effective and Safe Selenium Source of C57 Mice to Improve Growth Performance, Regulate Selenium Deposition, and Promote Antioxidant Capacity. Biol Trace Elem Res 2022; 200:2247-2258.

Abstract
Selenium-enriched polysaccharide (SeEPS) was prepared by reducing Se(IV) to elemental selenium and organic selenium in polysaccharide medium by the obtained Enterobacter cloacae strain Z0206 under aerobic conditions. In the present study, we focused on investigating the role of short-term supplementation of SeEPS at supernutritional doses in the regulation of growth performance, liver damage, antioxidant capacity, and selenium (Se) accumulation in C57 mice. Thirty-two C57 mice were randomly divided into four groups: the control group was gavaged with equal volume of phosphate-buffered saline, while the sodium selenite (Na2SeO3), selenomethionine (SeMet), and SeEPS groups were gavaged with 0.5 mg Se/kg BW of Na2SeO3, SeMet, and selenium-enriched polysaccharide (n = 8), respectively. We examined liver injury indicators, antioxidant capacity in the serum and liver, selenium deposition at different sites, selenoprotein levels, and selenocysteine-synthesizing and degradation-associated gene expression in mouse livers. SeEPS supplementation dramatically increased average daily weight gain but reduced the feed-to-gain ratio (F/G) of mice (P < 0.05). Compared to Na2SeO3 and SeMet supplementation, SeEPS supplementation at supernutritional doses did not cause the liver damage. SeEPS supplementation also markedly enhanced total antioxidant capacity (T-AOC), catalase (CAT), glutathione peroxidase (GSH-PX), and total superoxide dismutase (T-SOD) activities but reduced malondialdehyde (MDA) levels in the liver and serum (P < 0.05), while significantly increasing selenocysteine-synthesizing and degradation-related gene (SEPHS2, SEPSECS, Secisbp, Scly) expression at the mRNA level (P < 0.05), thus upregulating the mRNA levels of selenoproteins (SELENOP, SELENOK) (P < 0.05). We suggest that SeEPS could be a potential replacement for inorganic selenium to improve animals' growth performance, promote antioxidant capacity, and regulate selenium deposition.
