Reconstitución de la inmunidad celular T frente a citomegalovirus y control de la viremia en el paciente receptor de trasplante alogénico de precurso…

2015

Durante los últimos años la incidencia de la enfermedad orgánica causada por el Citomegalovirus (EOC) en los pacientes receptores de un trasplante alogénico de células precursoras hemotopoyéticas ha disminuido por el uso profiláctico o anticipado del ganciclovir e, indirectamente, el advenimiento de procedimientos muy sensibles para detectar la presencia del CMV en la sangre periférica (viremia): la PCR y la prueba de la antigenemia pp65 (AG). Aun así, la EOC continúa siendo una causa demasiado frecuente de morbididad y mortalidad en estos pacientes. Además, la administración profiláctica generalizada de ganciclovir predispone al paciente a sufrir infecciones bacterianas y fúngicas graves d…

Parámetros biológicos predictivos de la infección activa precoz por Citomegalovirus en el trasplante alogénico de precursores hematopoyéticos

2021

El trasplante alogénico de células precursoras hematopoyéticas es la única solución curativa para un variado número de neoplasias hematológicas de alto riego. Por esta razón, la infección sistémica causada por CMV ocasiona frecuente morbilidad y mortalidad en el paciente receptor de este tipo de trasplantes. En la actualidad se emplean dos estrategias terapéuticas. Sin embargo, ninguna está exenta de riesgos y ambas son mejorables. Disponer de marcadores biológicos que permitan estratificar a los pacientes de acuerdo al riesgo de desarrollo de infección sistémica haría posible una profilaxis dirigida, lo que resultaría en una menor toxicidad para el paciente y en menor incidencia de complic…

From endosomes onwards : membranes, lysosomes and viral capsid interactions

2009

Kirsi Pakkanen haki väitöstutkimuksessaan monitieteellisen lähestymistavan avulla uusia näkökulmia virustutkimukseen. Tutkimus tuo uutta tietoa lipidikalvojen merkityksestä viruksen ja viruksen isäntäsolun elämässä. Tutkimuksessa selvisi, että koiran parvovirus, jota tutkimuksessa käytettiin mallina parvoviruksille ja yleisemmin vaipattomille viruksille, tarvitsee tietynlaisia isäntäsolun lipidikalvojen ominaisuuksia voidakseen vapautua solunsisäisten endosomirakkuloiden sisältä. Erityisen tärkeää tässä vapautumisessa näytti olevan kalvojen juoksevuus sekä jäykkien alueiden hallittu järjestäytyminen kolesterolin avulla. Hyödyntämällä molekyylejä, lääkeaineita, jotka muuttavat kolesteroliavu…

Data from: Parasitic wasp-associated symbiont affects plant-mediated species interactions between herbivores

2018

Microbial mutualistic symbiosis is increasingly recognised as a hidden driving force in the ecology of plant–insect interactions. Although plant‐associated and herbivore‐associated symbionts clearly affect interactions between plants and herbivores, the effects of symbionts associated with higher trophic levels has been largely overlooked. At the third‐trophic level, parasitic wasps are a common group of insects that can inject symbiotic viruses (polydnaviruses) and venom into their herbivorous hosts to support parasitoid offspring development. Here, we show that such third‐trophic level symbionts act in combination with venom to affect plant‐mediated interactions by reducing colonisation o…

Experimental Evolution Reveals a Genetic Basis for Membrane-Associated Virus Release

2021

Many animal viruses replicate and are released from cells in close association to membranes. However, whether this is a passive process or is controlled by the virus remains poorly understood. Importantly, the genetic basis and evolvability of membrane-associated viral shedding have not been investigated. To address this, we performed a directed evolution experiment using coxsackievirus B3, a model enterovirus, in which we repeatedly selected the free-virion or the fast-sedimenting membrane-associated viral subpopulations. The virus responded to this selection regime by reproducibly fixing a series of mutations that altered the extent of membrane-associated viral shedding, as revealed by fu…

More nature in the city

2020

According to projects and practices that the Italian botanists and ecologists are carrying out for bringing “more nature in the city”, new insights for a factual integration between ecological perspectives and more consolidated aesthetic and agronomic approaches to the sustainable planning and management of urban green areas are provided.
