IFNG-mediated immune responses enhance autophagy against Mycobacterium tuberculosis antigens in patients with active tuberculosis
(Taylor & Francis, 2014-11)Protective immunity against Mycobacterium tuberculosis (Mtb) requires IFNG. Besides, IFNG-mediated induction of autophagy suppresses survival of virulent Mtb in macrophage cell lines. We investigated the contribution of ... -
Lipoxygenase activation in peanut seed cultivars resistant and susceptible to Aspergillus parasiticus colonization
(American Phytopathological Society, 2014-12)Accumulative evidence indicates that the lipoxygenase (LOX) pathway plays a significant role in the Aspergillus–seed interaction, such as interfering with activities of endogenous fungal oxylipins or producing antimicrobial ... -
Fitness of drug resistant Mycobacterium tuberculosis and the impact on the transmission among household contacts
(Elsevier, 2014-12)There has been an on-going debate on whether the development of drug resistance in Mycobacterium tuberculosis reduces its relative fitness and its ability to cause disease. The aim of this study was to explore this ... -
An integrative analysis of post-translational histone modifications in the marine diatom Phaeodactylum tricornutum
(BioMed Central, 2015)Background: Nucleosomes are the building blocks of chromatin where gene regulation takes place. Chromatin landscapes have been profiled for several species, providing insights into the fundamental mechanisms of ... -

Estudio de la relación del virus de la Bursitis Infecciosa con su hospedador. Análisis de la respuesta inmune y de la función y localización de la proteína viral VP5
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2015)Las aves representan un eslabón fundamental en la economía internacional. A nivel mundial, alrededor del 40% de la carne consumida es de origen aviar. La industria avícola ha experimentado en los últimos años un crecimiento ... -
Population structure and genetic diversity characterization of a sunflower association mapping population using SSR and SNP markers
(BMC, 2015-02)Background: Argentina has a long tradition of sunflower breeding, and its germplasm is a valuable genetic resource worldwide. However, knowledge of the genetic constitution and variability levels of the Argentinean germplasm ... -
ASR1 transcription factor and its role in metabolism
(Taylor & Francis, 2015-03)Asr1 (ABA, stress, ripening) is a plant gene widely distributed in many species which was discovered by differential induction levels in tomato plants subjected to drought stress conditions. ASR1 also regulates the expression ... -
Estrategia de inmunoprofilaxis para la prevención de la rabia paresiante utilizando un virus canarypox recombinante = Immunoprophylaxis strategy for the prevention of paralytic rabies using a recombinant canarypox virus
(Servicio Nacional de Sanidad y Calidad Agroalimentaria (SENASA), 2015-03)La rabia paresiante es una enfermedad causada por el virus rábico transmitido por el vampiro común. En el norte de nuestro país, se registran anualmente un número limitado de casos por lo que es necesaria la implementación ... -
Mycobacterium bovis infection in a horse with granulomatous enterocolitis
(Sage Publications, 2015-03)A 2-year-old dappled Percheron horse had a wasting condition that did not respond to antibiotic treatments and ultimately resulted in death. Thickening of the wall of the large colon and enlargement of the mesenteric lymph ... -
