Exosomes Isolated from Ascites of T-Cell Lymphoma-Bearing Mice Expressing Surface CD24 and HSP-90 Induce a Tumor-Specific Immune Response
(2017-03-16)Extracellular vesicles (EVs), including endosome-derived nanovesicles (exosomes), are involved in cell–cell communication. Through transfer of their molecular contents, extracellular nanovesicles can alter the function of ... -
Expanding the benefits of Tnt1 for the identification of dominant mutations in polyploid crops: A single allelic mutation in the MsNAC39 gene produces multifoliated alfalfa
(Frontiers Media, 2022-04)Most major crops are polyploid species and the production of genetically engineered cultivars normally requires the introgression of transgenic or gene-edited traits into elite germplasm. Thus, a main goal of plant research ... -

(Elsevier España, 2019-12)Bovine leukemia virus (BLV) is an important cattle pathogen that causes major economic losses worldwide, especially in dairy farms. The use of animal models provides valuable insight into the pathogenesis of viral infections. ... -
An experimental reproduction of necrotic enteritis In broiler chickens
(2016)Clostridium perfringens is the main causative agent of avian necrotic enteritis (NE), an enteric infectious disease considered among the most important diseases in the poultry industry. Currently, there are numerous reports ... -
Experimental selection of long‐term intracellular mycobacteria
(Wiley, 2014-09)Some intracellular bacteria are known to cause long‐term infections that last decades without compromising the viability of the host. Although of critical importance, the adaptations that intracellular bacteria undergo ... -
Exploring sunflower responses to Sclerotinia head rot at early stages of infection using RNA‑seq analysis
(Springer Nature, 2020-08)Sclerotinia head rot (SHR), caused by the necrotrophic fungus Sclerotinia sclerotiorum, is one of the most devastating sunflower crop diseases. Despite its worldwide occurrence, the genetic determinants of plant resistance ... -
Exploring the ancestral mechanisms of regulation of horizontally acquired nitrogenases
(Springer, 2015-10)The vast majority of Pseudomonas species are unable to fix atmospheric nitrogen. Although several studies have demonstrated that some strains belonging to the genus Pseudomonas sensu stricto do have the ability to fix ... -
Exploring the association between polymorphisms at 3’UTR SLC11A1 gene microsatellites and resistance to tuberculosis: A case-control study in Bos taurus dairy cattle
(2018-04)Bovine tuberculosis is a contagious infectious disease that causes significant economic impact in dairy and meat farms throughout the world. Multiple factors, including host genome, determine the outcome of the infection. ... -
Exploring the factors involved in the absence of parasitism of Chaetosiphon fragaefolii by generalist parasitoids in strawberry
(Springer, 2020-08)Chaetosiphon fragaefolii Cockerell (Hemiptera: Aphididae) is a worldwide strawberry pest with scarce records of parasitoids for its control. The parasitization rate of two generalist parasitoids, Aphidius colemani Viereck ... -
Exploring the Intrinsic Limits of Nitrogenase Transfer from Bacteria to Eukaryotes
(Springer, 2013-08)Biological nitrogen fixation is widespread among the Eubacteria and Archae domains but completely absent in eukaryotes. The lack of lateral transfer of nitrogen-fixation genes from prokaryotes to eukaryotes has been partially ... -
Exploring the role of the NO‑detoxifying enzyme HmpA in the evolution of domesticated Alfalfa Rhizobia
(Springer, 2022-02)We have previously shown the extensive loss of genes during the domestication of alfalfa rhizobia and the high nitrous oxide emission associated with the extreme genomic instability of commercial inoculants. In the present ... -

Expression analysis of genes putatively associated with hygienic behavior in selected stocks of Apis mellifera L. from Argentina
(2017-11)Hygienic behavior is an economically beneficial, heritable trait, which has evolved to limit the impact of honeybee pathogens. Selecting and breeding colonies with high levels of hygienic behavior has become a feasible and ... -
Expression-based analysis of genes related to single nucleotide polymorphism hits associated with bovine leukemia virus proviral load in Argentinean dairy cattle
(Elsevier, 2021-02)In dairy cattle infected with bovine leukemia virus (BLV), the proviral load (PVL) level is directly related to the viral transmission from infected animals to their healthy herdmates. Two contrasting phenotypic groups can ... -
