Host-Derived CD8+ Dendritic Cells Protect Against Acute Graft-versus-Host Disease after Experimental Allogeneic Bone Marrow Transplantation
2014
Graft-versus-host disease (GVHD) is a frequent life-threatening complication after allogeneic hematopoietic stem cell transplantation (HSCT) and induced by donor-derived T cells that become activated by host antigen-presenting cells. To address the relevance of host dendritic cell (DC) populations in this disease, we used mouse strains deficient in CD11c(+) or CD8α(+) DC populations in a model of acute GVHD where bone marrow and T cells from BALB/c donors were transplanted into C57BL/6 hosts. Surprisingly, a strong increase in GVHD-related mortality was observed in the absence of CD11c(+) cells. Likewise, Batf3-deficient (Batf3(-/-)) mice that lack CD8α(+) DCs also displayed a strongly incr…
Myeloperoxidase mediates neutrophil activation by association with CD11b/CD18 integrins.
2004
Recruitment and activation of polymorphonuclear neutrophils (PMNs) reflects a primary immunological response to invading pathogens and has also emerged as a hallmark of vascular inflammation. One of the principal enzymes released upon PMN activation is myeloperoxidase (MPO), a heme protein that not only generates cytotoxic oxidants but also impacts deleteriously on nitric oxide-dependent signaling cascades within the vasculature. Because MPO also associates with the membrane of PMN, we evaluated whether MPO could also function as an autocrine modulator of PMN activation. The extent of PMN membrane-associated MPO was elevated in patients with acute inflammatory vascular disease compared with…
Les vicissituds de la traducció al castellà d’elements heroics i medievals del Canigó, de Jacint Verdaguer. El cas de «La Maladeta»
2014
Resum: En aquest article s’estudien les dificultats de traduir «La Maladeta», un passatge de Canigó, de Jacint Verdaguer. Creiem que aquest fragment és prou representatiu de la temàtica del poema èpic verdaguerià, ja que ha estat un dels més traduïts a totes les llengües i, a més, conté elements heroics i medievals del poema. És per això que hem cregut oportú de fer l’anlàlisi de la traducció dels fragments, per poder treure’n unes conclusions que ens serveixin per avaluar la qualitat de cada versió.Paraules clau: Verdaguer, Canigó, medieval, traducció. Abstract: In this article we study the translation’s difficulties of «La Maladeta», an extract of Canigó by Jacint Verdaguer. We think that…
Il nodo mediterraneo: Corona d'Aragona e Sicilia nella politica di Bonifacio VIII
2003
La politica di papa Bonifacio VIII nella questione del Vespro e in relazione al nuovo regno di Sicilia di Federico III. Si rileva la complessità e l'ambiguità di tale politica, perseguita fin da prima dell'elezione pontificia, specie nei confronti dei re angioini. Si sottolinea l'importante ruolo assunto nella politica mediterranea da Giacomo II d'Aragona.
Josefa Verride y Martina de los Ángeles. El difícil camino hacia la santidad.
2016
Resumen: A través de la información que nos proporcionan las vidas de Josefa Verride, tercera de la orden dominica en Huesca y Martina de los Ángeles, religiosa de la misma orden, fundadora del convento de san Pedro de Benabarre, pretendo aportar nuevas ideas acerca del proceso de adquisición de la fama de santidad de algunas mujeres en la Edad Moderna española. Las órdenes religiosas debieron idear estrategias que ayudasen a legitimar y consolidar la fama de santidad de estas mujeres. Una de estas estrategias fue la vinculación de las religiosas con otras mujeres con fama de santidad, creando genealogías femeninas que les permitiesen perpetuar su memoria y prestigio a lo largo del tiempo. …
Autobiografía y memoria en el diario de viajes del VI Conde de Fernán Núñez = Autobiography and Memory in the Travel Diary of the VI Count of Fernán …
2016
ResumenEl viaje fue una constante en la vida de don Carlos José Gutiérrez de los Ríos, VI conde de Fernán Núñez (1742-1795). A través de ellos pudo cumplir con su servicio al rey y con sus responsabilidades como cabeza del linaje. Asimismo pudo completar su formación y satisfacer anhelos más personales. De todos sus viajes, los realizados dentro y fuera de España, guardó memoria escrita en un diario de viajes, un documento que, en formato manuscrito, se conservó en su archivo familiar. En un periodo cronológico en el que el viaje y su relato adquirieron especial protagonismo, este trabajo analiza el papel que el viaje jugó en la vida y memoria del VI conde de Fernán Núñez y su impronta dent…
Translation of HTT mRNA with expanded CAG repeats is regulated by the MID1-PP2A protein complex.
2012
Expansion of CAG repeats is a common feature of various neurodegenerative disorders, including Huntington's disease. Here we show that expanded CAG repeats bind to a translation regulatory protein complex containing MID1, protein phosphatase 2A and 40S ribosomal S6 kinase. Binding of the MID1-protein phosphatase 2A protein complex increases with CAG repeat size and stimulates translation of the CAG repeat expansion containing messenger RNA in a MID1-, protein phosphatase 2A- and mammalian target of rapamycin-dependent manner. Our data indicate that pathological CAG repeat expansions upregulate protein translation leading to an overproduction of aberrant protein and suggest that the MID1-com…
The E3 Ubiquitin Ligase MID1 Catalyzes Ubiquitination and Cleavage of Fu
2014
Sonic Hedgehog (SHH)-GLI signalling plays an important role during embryogenesis and in tumorigenesis. The survival and growth of several types of cancer depend on autonomously activated SHH-GLI signalling. A protein complex containing the ubiquitin-ligase MID1 and protein phosphatase 2A (PP2A) regulates the nuclear localization and transcriptional activity of GLI3, a transcriptional effector molecule of SHH, in cancer cell lines with autonomously activated SHH signalling. However, the exact molecular mechanisms that mediate the interaction between MID1 and GLI3 remained unknown. Here, we show that MID1 catalyses the ubiquitination and proteasomal cleavage of the GLI3-regulator Fu. Our data…
Sorption of V and VI group metalloids (As, Sb, Te) on modified peat sorbents
2016
AbstractThe present work investigates arsenic, antimony and tellurium sorption using iron modified peat. The results were obtained using batch tests and the sorption was studied as a function of initial metalloid concentration, pH and sorption time, as well as the presence of competing substances. The obtained results indicate that modification of peat with Fe compounds significantly enhances the sorption capacity of the sorbents used for sorption of arsenic, antimony and tellurium. The optimal pH interval for the sorption of Sb(III) is 6.5–9 and for As(V) and Sb(V) – 3–6, while As(III) and tellurium sorption using Fe-modified peat is favourable in a wider interval of 3–9. The presence of c…
