Efectos de la i-logica capitalista en la violencia de genero
2015
Las autoras de este artículo reflexionan sobre los cierres y recortes en recursos de servicios sociales en general y de atención a las mujeres víctimas de violencia de género en particular, concluyendo que es la ideología mercantilista aplicada a los recursos sociales de atención a los más necesitados, la principal causante de que estos no funcionen adecuadamente y de que las mujeres víctimas de violencia en muchos casos no reciban la atención que seria necesaria.
Protección integral de la mujer con diversidad funcional en supuestos de violencia de género
2016
"Protección integral de la mujer con diversidad funcional en supuestos de violencia de género" es la culminación de cuatro intensos años de apasionante investigación jurídica, dirigidos por la Doctora Elena Martínez García, la cual partió de una temática especialmente novedosa en el ámbito del derecho, pero que nos inducía a pensar que detrás de ella existía una realidad muchas veces silenciada. A partir de cuestiones tan concretas como igualdad, género, discapacidad o violencia machista, hemos visto como en la última fase de nuestro trabajo, el mismo ha terminado por coincidir con un legislador y unas políticas sociales mucho más abiertas e inclusivas, permitiéndonos recorrer en paralelo y…

Soft X-ray Tomography Reveals HSV-1-Induced Remodeling of Human B Cells.
2022
Upon infection, viruses hijack the cell machinery and remodel host cell structures to utilize them for viral proliferation. Since viruses are about a thousand times smaller than their host cells, imaging virus-host interactions at high spatial resolution is like looking for a needle in a haystack. Scouting gross cellular changes with fluorescent microscopy is only possible for well-established viruses, where fluorescent tagging is developed. Soft X-ray tomography (SXT) offers 3D imaging of entire cells without the need for chemical fixation or labeling. Here, we use full-rotation SXT to visualize entire human B cells infected by the herpes simplex virus 1 (HSV-1). We have mapped the temporo…

Nonlinearities in plant RNA virus fitness
2012
Una de las mayores amenazas tanto para la salud humana y animal, como para la agronomía es la emergencia de nuevas enfermedades infecciosas, la mayoría de las cuales están causadas por los virus de RNA. La emergencia viral es un problema complejo que consista en la adquisición de la variación genética, por mutación o recombinación, dentro de la población viral en el huésped reservorio la cual podría facilitar la capacidad de infectar de manera eficiente nuevos huéspedes. Los virus de RNA presentan a una evolucionabilidad extraordinaria por sus grandes tamaños poblacionales, cortos tiempos de generación y altas tasas de mutación y recombinación. Comprender los mecanismos evolutivos que podrí…
Rab33B and its autophagic Atg5/12/16L1 effector assist in hepatitis B virus naked capsid formation and release
2015
Hepatitis B virus morphogenesis is accompanied by the production and release of non-enveloped capsids/nucleocapsids. Capsid particles are formed inside the cell cytosol by multimerization of core protein subunits and ultimately exported in an uncommon coatless state. Here, we investigated potential roles of Rab GTPases in capsid formation and trafficking by using RNA interference and overexpression studies. Naked capsid release does not require functions of the endosome-associated Rab5, Rab7 and Rab27 proteins, but depends on functional Rab33B, a GTPase participating in autophagosome formation via interaction with the Atg5-Atg12/Atg16L1 complex. During capsid formation, Rab33B acts in conju…
Peptide-mediated interference with baculovirus transduction
2007
Baculovirus represents a multifunctional platform with potential for biomedical applications including disease therapies. The importance of F3, a tumor-homing peptide, in baculovirus transduction was previously recognized by the ability of F3 to augment viral binding and gene delivery to human cancer cells following display on the viral envelope. Here, F3 was utilized as a molecular tool to expand understanding of the poorly characterized baculovirus-mammalian cell interactions. Baculovirus-mediated transduction of HepG2 hepatocarcinoma cells was strongly inhibited by coincubating the virus with synthetic F3 or following incorporation of F3 into viral nucleocapsid by genetic engineering, th…
Generation and Applications of HPV Pseudovirions Using Vaccinia Virus
2005
This chapter outlines the generation and application of human papillomavirus type 33 (HPV 33) pseudovirions. These pseudovirions are structurally indistinguishable from native virions and are therefore valuable tools for the study of papillomavirus/cell interactions. The method describes (1) the construction of vaccinia viruses recombinant for the major and minor HPV capsid proteins, L1 and L2, respectively, (2) the transfection of Cos7 cells with a marker plasmid replicating to high copy numbers, (3) the expression of L1 and L2 using the vaccinia virus expression system, (4) the extraction, purification, and analysis of HPV-33 pseudovirions, (5) pseudoinfection assays, (6) pre- and post-at…
CVB3 VP1 interacts with MAT1 to inhibit cell proliferation by interfering with Cdk-activating kinase complex activity in CVB3-induced acute pancreati…
2021
Coxsackievirus B3 (CVB3) belongs to the genus Enterovirus of the family Picornaviridae and can cause acute acinar pancreatitis in adults. However, the molecular mechanisms of pathogenesis underlying CVB3-induced acute pancreatitis have remained unclear. In this study, we discovered that CVB3 capsid protein VP1 inhibited pancreatic cell proliferation and exerted strong cytopathic effects on HPAC cells. Through yeast two-hybrid, co-immunoprecipitation, and confocal microscopy, we show that Menage a trois 1 (MAT1), a subunit of the Cdk-Activating Kinase (CAK) complex involved in cell proliferation and transcription, is a novel interaction protein with CVB3 VP1. Moreover, CVB3 VP1 inhibited MAT…
