Differential activation of chicken gamma delta T cells from different tissues by Toll-like receptor 3 or 21 ligands. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2022; 131:104391. [PMID: 35271861 DOI: 10.1016/j.dci.2022.104391] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Revised: 03/04/2022] [Accepted: 03/04/2022] [Indexed: 06/14/2023]
Abstract
Gamma delta (γδ) T cells are highly enriched in mucosal barrier sites including intestinal tissues where microbial infections and tumors often originate in mammals. Human γδ T cells recognize stress antigens and microbial signals via their T cell receptor (TCR), natural killer (NK) receptors, and pattern recognition receptors. However, little is known about antigens or ligands capable of stimulating chicken γδ T cells. The results of the present study demonstrated that polyinosinic-polycytidylic acid (poly(I:C)), a Toll-like receptor (TLR)3 ligand, significantly induced upregulation of CD8α molecules on circulating and lung γδ T cells. Moreover, poly(I:C) stimulation induced interferon (IFN)-γ production from splenic and lung CD8α+ γδ T cells while Cytosine-phosphate-Guanine oligodeoxynucleotides (CpG-ODN) 2007, a TLR21 ligand, stimulation induced IFN-γ production by circulating γδ T cells. Neither poly(I:C) nor CpG-ODN 2007 stimulation elicited degranulation of γδ T cells. Additionally, the results revealed that CpG-ODN 2007 induced IFN-γ production from TCR-stimulated γδ T cells sorted from spleen. In our experiments, isopentenyl pyrophosphate (IPP), 4-hydroxy-3-methyl-but-2-enyl pyrophosphate (HMBPP), or zoledronate (Zol) stimulation did not induce IFN-γ production or degranulation in γδ T cells. Taken together, a combination of CpG-ODN 2007 and anti-CD3ε monoclonal antibodies (mAbs) can stimulate chicken γδ T cells and induce production of IFN-γ by these cells while IFN-γ production by γδ T cells induced by stimulation of poly(I:C) needs signals from other cells. These results suggest that chicken γδ T cells can sense invading pathogens via TLRs and produce IFN-γ as a first line of defense.

Nihashi Y, Shinji S, Umezawa K, Shimosato T, Ono T, Kagami H, Takaya T. Myogenetic oligodeoxynucleotide complexed with berberine promotes differentiation of chicken myoblasts. Anim Sci J 2021; 92:e13597. [PMID: 34309956 DOI: 10.1111/asj.13597] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 05/20/2021] [Accepted: 07/05/2021] [Indexed: 11/29/2022]
Abstract
Myoblasts are myogenic precursors that develop into myotubes during muscle formation. Improving efficiency of myoblast differentiation is important for advancing meat production by domestic animals. We recently identified novel oligodeoxynucleotides (ODNs) termed myogenetic ODNs (myoDNs) that promote the differentiation of mammalian myoblasts. An isoquinoline alkaloid, berberine, forms a complex with one of the myoDNs, iSN04, and enhances its activities. This study investigated the effects of myoDNs on chicken myoblasts to elucidate their species-specific actions. Seven myoDNs (iSN01-iSN07) were found to facilitate the differentiation of chicken myoblasts into myosin heavy chain (MHC)-positive myotubes. The iSN04-berberine complex exhibited a higher myogenetic activity than iSN04 alone, which was shown to enhance the differentiation of myoblasts into myotubes and the upregulation of myogenic gene expression (MyoD, myogenin, MHC, and myomaker). These data indicate that myoDNs promoting chicken myoblast differentiation may be used as potential feed additives in broiler diets.

An integrated transcriptomics and metabolomics study of the immune response of newly hatched chicks to the cytosine-phosphate-guanine oligonucleotide stimulation. Poult Sci 2020; 99:4360-4372. [PMID: 32867980 PMCID: PMC7598132 DOI: 10.1016/j.psj.2020.06.017] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2019] [Revised: 05/26/2020] [Accepted: 06/19/2020] [Indexed: 11/13/2022] Open
Abstract
The immunological immaturity of the innate immune system during the first-week post-hatch enables pathogens to infect chickens, leading to the death of the animals. Current preventive solutions to improve the resistance of chicks to infections include vaccination, breeding, and sanitation. Other prophylactic solutions have been investigated, such as the stimulation of animal health with immunostimulants. Recent studies showed that administration of immune-modulators to one-day-old chicks, or in ovo, significantly reduces mortality in experimental bacterial or viral infection challenge models. Owing to a lack of molecular biomarkers required to evaluate chicken immune responses and assess the efficacy of vaccines or immune-modulators, challenge models are still used. One way to reduce challenge experiments is to define molecular signatures through omics approaches, resulting in new methodologies to rapidly screen candidate molecules or vaccines. This study aims at identifying a dual transcriptomics and metabolomics blood signature after administration of CpG-ODN (cytosine-phosphate-guanine oligodeoxynucleotides), a reference immune-stimulatory molecule. A clinical study was conducted with chicks and transcriptomics and metabolomics analyses were performed on whole-blood and plasma samples, respectively. Differentially expressed genes and metabolites with different abundance were identified in chicks treated with CpG-ODN. The results showed that CpG-ODN activated the innate immune system, within hours after administration, and its effect lasted over time, as metabolomics and transcriptomics profiles still varied 6 D after administration. In conclusion, through an integrated clinical omics approach, we deciphered in part the mode of action of CpG-ODN in post-hatch chicks.

Abstract
Ebola virus is the causative agent of Ebola virus disease, a severe, often fatal illness in humans. So far, there are no US Food and Drug Administration (FDA)-approved therapeutics directed against Ebola virus. Here, we selected the host factor Niemann-Pick C1 (NPC1), which has been shown to be essential for Ebola virus entry into host cytoplasm, as a therapeutic target for suppression by locked nucleic acid-modified antisense oligonucleotides. Screening of antisense oligonucleotides in human and murine cell lines led to identification of candidates with up to 94% knockdown efficiency and 50% inhibitory concentration (IC50) values in the submicromolar range. Selected candidate oligonucleotides led to efficient NPC1 protein knockdown in vitro without alteration of cell viability. Furthermore, they did not have immune stimulatory activity in cell-based assays. Treatment of Ebola-virus-infected HeLa cells with the most promising candidates resulted in significant (>99%) virus titer reduction, indicating that antisense oligonucleotides against NPC1 are a promising therapeutic approach for treatment of Ebola virus infection.

Abstract
OBJECTIVE To characterize activation and expression of immune genes of chicken macrophages after in vitro stimulation with lipopolysaccharide (LPS) and mouse erythrocytes. ANIMALS Five 15-day-old chickens and 2 BALB/c mice. PROCEDURES Macrophages were extracted from chicken bone marrow or peripheral blood and then stimulated with cytokines secreted from cell lines L929 and HD11. Stimulated chicken macrophages were further cocultured with LPS or mouse erythrocytes, and gene transcription of some distinctive cytokines was detected by use of a real-time PCR assay. RESULTS Morphological features and phagocytic function of macrophages were characterized. Activated macrophages had an elongated shape with a large cell nucleus, and they had phagocytic function. Distinctive genes encoding the surface marker gene CD11b were identified; high quantities of CD11b were transcribed. Relative transcription of chicken genes BF and BL in mature cells cocultured with both stimuli was lower than for control cells. However, the quantity of genes encoding M1- or M2-distinctive cytokines (interleukin [IL]-1β, IL-10, IL-12, inducible nitric oxide synthase, tumor necrosis factor-α, and transforming growth factor-β) that were transcribed differed significantly between stimulation with LPS and mouse erythrocytes. CONCLUSIONS AND CLINICAL RELEVANCE Chicken macrophages were differentially stimulated by LPS and mouse erythrocytes, which suggested that in vitro stimulation can distinctly influence the transcription and expression of immune genes of chicken macrophages.
