Three major bovine herpesvirus type 4 (BHV-4) glycoproteins have been described previously. By using monoclonal antibodies produced against BHV-4 envelope proteins from which the three major antigens had been removed by immunoaffinity, a fourth glycoprotein was identified. This protein (gp1) has a high Mr (greater than 300K), is detected about 8 h post-inoculation of infected cells and is strictly expressed as a gamma protein. Moreover, gp1 was identified by a polyclonal antiserum from an infected animal, indicating that this glycoprotein is an antigen recognized by the immune system of infected animals. [less ▲]

Brucella melitensis 16M is a Gram-negative alpha2-proteobacterium responsible for abortion in goats and for Malta fever in humans. This facultative intracellular pathogen invades into and survives within both professional and non-professional phagocytes. Signature-tagged mutagenesis (STM) was used to identify genes required for the in vivo pathogenesis of Brucella. A library of transposon mutants was screened in a murine infection model. Out of 672 mutants screened, 20 were not recovered after a 5 day passage in BALB/c mice. The attenuation of 18 mutants was confirmed using an in vivo competition assay against the wild-type strain. The 18 mutants were characterized further for their ability to replicate in murine macrophages and in HeLa cells. The sequences disrupted by the transposon in the mutants have homology to genes coding for proteins of different functional classes: transport, amino acid and DNA metabolism, transcriptional regulation, peptidoglycan synthesis, a chaperone-like protein and proteins of unknown function. The mutants selected in this study provide new insights into the molecular basis of Brucella virulence. [less ▲]

he aim of our work is to identify new genes and proteins involved in the control of the proliferation of thyroid cells as putative protooncogenes and antioncogenes. Several strategies are discussed. A first study has allowed to identify three new genes. Further search will use the differential display and gene arrays methodology. The role of the identified proteins coded by the genes is studied in vitro by the search of partner proteins by the double hybrid method and in vivo by mice gene knockout technology [less ▲]

The deltaretrovirus Bovine Leukemia Virus (BLV) is closely related to the Human T-cell leukemia virus-1 (HTLV-1). Cattle are the natural host of BLV where it integrates into B-cells, produces a lifelong infection. Most infected animals remain asymptomatic but following a protracted latency period about ~5% develop an aggressive leukemia/lymphoma, mirroring the disease trajectory of HTLV-1. Like the case in HTLV-1 the 5’LTR BLV provirus is transcriptionally silent in tumors, however the provirus is not entirely quiescent, constitutively express the BLV microRNAs in tumors. Using RNA-seq, we found that in addition to microRNAs, the BLV provirus also constitutively expresses two antisense transcripts in all BLV infected samples examined. The first transcript (AS1) has alternate potential polyadenylation sites generating a short transcript of ~600bp (AS1-S) and a less abundant longer transcript of ~2200bp (AS1-L). Alternative splicing also creates a second transcript of ~400bp (AS2) utilizing the first exon of AS1. Production of AS transcripts from the 3’LTR was supported by reporter assays demonstrating that the BLV LTR has substantial and Tax-independent antisense promoter activity. BLV AS transcripts predominantly localize in the nucleus. Examination of protein coding potential showed AS2 to be non-coding, while the AS1-S/L transcripts coding potential is ambiguous, with a small potential open reading frame (ORF) of 264bp present. The AS1-L transcript overlaps the BLV microRNAs transcribed in the sense direction. Using high throughput sequencing of RNA-ligase-mediated (RLM) 5' RACE products, we show that the perfect complementary between the transcripts leads to RNA-induced silencing complex (RISC) mediated cleavage of AS1-L. Furthermore, experiments using BLV proviruses where the microRNAs were removed or inverted point to additional transcriptional interactions between the two viral RNA species. Knock down of AS1-S/L using locked nucleic acids (LNAs) showed no obvious effect on the cells phenotype. While a detailed elucidation of the BLV antisense transcripts function remains in the future, the constitutive expression in all samples examined, points to a vital role for the transcripts in the life cycle and oncogenic potential of BLV.

Some varieties of wheat are resistant to some aphid clones of the English Grain Aphid (Sitobion avenae). This study used 2D-DIGE coupled with protein identification by Maldi-Tof-MS to compare the proteome patterns of English Grain Aphids on resistant (Llareta) and susceptible (Huayún) wheat lines. Aphids were exposed to wheat during 2 weeks (short term: ST) and 4 weeks (long term: LT). Four treatments were compared: Llareta-ST, Llareta-LT, Huayún-ST, Huayún-LT. Experiment was conducted using different Sitobion avenae clones whose symbionts were previously characterized. Results showed that aphids had low performance on resistant plants. Seventy-two protein spots showed significant quantitative differences among the four treatment groups. Proteomic approach will allow a better understanding of interaction mechanisms between aphids and wheat. [less ▲]

Four Fumaria species (F. vaillantii Loisel, F. parviflora Lam., F. rostellata Knaf and F. jankae Hausskn.) were analysed in order to determine the presence of the isoquinoline alkaloids allocryptopine, chelidonine, protopine, bicuculline, sanguinarine, cheleritrine, stylopine, and hydrastine through an HPLC-DAD method. Protopine and sanguinarine were present in all extracts. Bicuculline and stylopine were found in F. vaillantii and F. parviflora, whilst chelidonine was identified only in F. vaillantii and hydrastine in F. jankae, so they represent potential taxonomic markers that differentiate the four plants. The richest species in isoquinoline alkaloids was F. parviflora. Our study showed significant differences between the four Fumaria species, both qualitative and quantitative. [less ▲]

The C-type lectin domain containing (CLEC) receptors including CD209 are expressed in vivo by monocytes, monocyte-derived macrophages and dendritic cells and by in vitro generated monocyte-derived cells. This paper reports the cloning and sequencing of a lectin molecule, CLEC4T1, in rainbow trout that is a homologue of the CLEC4 family. The expression pattern of the CLEC4T1 was investigated in vivo after infection with a bacterial pathogen and in cultured macrophages after modulation with microbial mimics. Trout CLEC4T1 was highly expressed in spleen and head kidney following infection with Yersinia ruckeri. Expression could also be induced in macrophage cultures by LPS but not by Poly I:C, and suggests that the regulation of CLEC4T1 expression in trout varies according to the nature of the stimulant. A polyclonal CLEC4T1 antibody was generated and validated by Western blotting for use in evaluation of CLEC4T1(+) cells by flow cytometry analysis. Freshly isolated adherent trout head kidney cultures, potentially containing macrophages and dendritic cell precursors, showed an increase of CLEC4T1(+) cells (assessed by flow cytometry) upon stimulation with recombinant interleukin-4/13A. The results suggest that CLEC4T1 is a useful marker for further characterisation of monocyte derived antigen presenting cells in fish. [less ▲]
