Base genética del tropismo de lentivirus de pequeños rumiantes y estudio de la resistencia innata por APOBEC3
Los lentivirus de pequeños rumiantes (SRLV), que incluyen al virus Visna/Maedi (VMV) y al de la artritis encefalitis caprina (CAEV), infectan ovejas y cabras distribuidas por todo el mundo causando un cuadro multisistémico ... -
Characterization of ovine A3Z1 restriction properties against small ruminant lentiviruses (SRLVs)
Intrinsic factors of the innate immune system include the apolipoprotein B editing enzyme catalytic polypeptide-like 3 (APOBEC3) protein family. APOBEC3 inhibits replication of different virus families by cytosine ... -
Detection of PrPSc in lung and mammary gland is favored by the presence of Visna/maedi virus lesions in naturally coinfected sheep
There are few reports on the pathogenesis of scrapie (Sc) and Visna/maedi virus (VMV) coinfections. The aim of this work was to study in vivo as well as post mortem both diseases in 91 sheep. Diagnosis of Sc and VMV ... -
Diagnosing infection with small ruminant lentiviruses of genotypes A and B by combining synthetic peptides in ELISA
The major challenges in diagnosing small ruminant lentivirus (SRLV) infection include early detection and genotyping of strains of epidemiological interest. A longitudinal study was carried out in Rasa Aragonesa sheep ... -
Expression analysis of lung miRNAs responding to ovine VM virus infection by RNA-seq
Background: MicroRNAs (miRNAs) are short endogenous, single-stranded, noncoding small RNA molecules of approximately 22 nucleotides in length. They regulate gene expression posttranscriptionally by silencing mRNA expression, ... -
Extensive rearing hinders Maedi-Visna Virus (MVV) infection in sheep
Maedi-Visna Virus (MVV) seroprevalence and its relationship with housing and mode of rearing of replacement ewe-lambs was investigated in 38 non-randomly selected sheep-flocks in Spain. They included extensive lamb-producing ... -
The extradomain a of fibronectin enhances the efficacy of lipopolysaccharide defective Salmonella bacterins as vaccines in mice
The Extradomain A from fibronectin (EDA) has an immunomodulatory role as fusion protein with viral and tumor antigens, but its effect when administered with bacteria has not been assessed. Here, we investigated the adjuvant ... -
Growth performance and clinicopathological analyses in lambs repetitively inoculated with aluminum-hydroxide containing vaccines or aluminum-hydroxide only
Aluminum (Al) hydroxide is an effective adjuvant used in sheep vaccines. However, Al-adjuvants have been implicated as potential contributors to a severe wasting syndrome in sheep— the so-called ovine autoimmune-inflammatory ... -
Iberian red deer: paraphyletic nature at mtDNA but nuclear markers support its genetic identity
Red deer populations in the Iberian glacial refugium were the main source for postglacial recolonization and subspecific radiation in north-western Europe. However, the phylogenetic history of Iberian red deer (Cervus ... -
Identificación de lentivirus de pequeños rumiantes en granulomas post-vacunales y evaluación de métodos de diagnóstico y selección genética en la lucha frente a la infección
Esta tesis plantea tres objetivos que se desarrollarán en tres capítulos independientes, correspondientes a sus respectivas publicaciones. Por un lado, se ha caracterizado la presencia y replicación de SRLV en macrófagos ... -
Identification of the ovine mannose receptor and its possible role in Visna/Maedi virus infection
This study aims to characterize the mannose receptor (MR) gene in sheep and its role in ovine visna/maedi virus (VMV) infection. The deduced amino acid sequence of ovine MR was compatible with a transmembrane protein having ... -
Immunization against small ruminant lentiviruses
Multisystemic disease caused by Small Ruminant Lentiviruses (SRLV) in sheep and goats leads to production losses, to the detriment of animal health and welfare. This, together with the lack of treatments, has triggered ... -
Innate immunity against small ruminant lentiviruses (SRLV): characterization of APOBEC3-derived restriction
En esta tesis se han llevado a cabo los siguientes estudios: 1. Identificación y caracterización de la restricción por APOBEC3 ovino frente a los SRLV. Se han estudiado dos tipos celulares que muestran restricción natural ... -
Lack of relationship between Visna/maedi infection and scrapie resistance genetic markers
(Instituto Nacional de Investigacion y Tecnologia Agraria y Alimentaria (INIA), 2014) Artículo / ArtikuluaThe relationship between Visna/maedi virus (VMV) antibody status and scrapie genetic resistance of 10,611 Rasa Aragonesa sheep from 17 flocks in Aragón (Spain) was investigated. The fifteen most common PRNP gene haplotypes and ... -
Lentinula edodes β-glucan enriched diet induces pro- and anti-inflammatory macrophages in rabbit
β-glucans exhibited in cell walls of several pathogens as bacteria or fungi are sensed by pathogen recognition receptors such as scavenger receptors present in antigen presenting cells, i.e., macrophages. β-glucans obtained ... -
Maedi-visna virus infection of ovine mammary epithelial cells
The aim of this work was to perform a complete study of maedi-visna virus (MVV) infected mammary glands of naturally-infected sheep, and to determine if cells other than macrophages undergo a productive viral infection in ... -
Mannose receptor may be involved in small ruminant lentivirus pathogenesis
Thirty-one sheep naturally infected with small ruminant lentiviruses (SRLV) of known genotype (A or B), and clinically affected with neurological disease, pneumonia or arthritis were used to analyse mannose receptor (MR) ... -
Molecular signature of aluminum hydroxide adjuvant in ovine PBMCs by integrated mRNA and microRNA transcriptome sequencing
There have been few in vivo studies on the effect of aluminum hydroxide adjuvant and its influence on the immune response to vaccination. In this study, lambs received a parallel subcutaneous treatment with either commercial ... -
Ovine TRIM5α can restrict visna/maedi virus
The restrictive properties of tripartite motif-containing 5 alpha (TRIM5α) from small ruminant species have not been explored. Here, we identify highly similar TRIM5α sequences in sheep and goats. Cells transduced with ... -
Post-entry blockade of small ruminant lentiviruses by wild ruminants
Small ruminant lentivirus (SRLV) infection causes losses in the small ruminant industry due to reduced animal production and increased replacement rates. Infection of wild ruminants in close contact with infected domestic ...
