6-O sulfated and N-sulfated Syndecan-1 promotes baculovirus binding and entry into mammalian cells.

2013

Baculoviruses are insect-specific viruses commonly found in nature. They are not able to replicate in mammalian cells but can transduce them when equipped with an appropriate mammalian cell active expression cassette. Although the viruses have been studied in several types of mammalian cells from different origins, the receptor that baculovirus uses to enter or interact with mammalian cells has not yet been identified. Due to the wide tropism of the virus, the receptor has been suggested to be a generally found cell surface molecule. In this article, we investigated the interaction of baculovirus and mammalian cell surface heparan sulfate proteoglycans (HSPG) in more detail. Our data show t…

Intracellular interplay between canine parvovirus with nuclear pore complex and effect of infection on RNA synthesis

2015

Koiran parvovirus (CPV) on halkaisijaltaan 26 nm vaipaton virus. Ikosahedraalinen kapsidi sisältää yksijuosteisen ~5kb DNA-genomin. CPV sisälleotetaan soluun endosytoosilla, jonka jälkeen se kulkeutuu endosomin sisällä kohti tumaa. CPV vapautuu solulimaan tumaa ympäröivistä lysosomeista. Genomin replikaatio ja uusien virionien kasautuminen tapahtuvat tumassa. Aikaisemmin on oletettu, että parvovirukset todennäköisesti pääsisivät tumaan tumahuokosen (NPC) kautta. Uudet tutkimukset kuitenkin viittaavat siihen että siirtyminen tumaan voisi tapahtua toista reittiä käyttäen. CPV ja NPC proteiinien (Nup) kolokalisaatio-kokeissa selvitettiin voidaanko tiettyjä vuorovaikutuksia havaita ja missä mah…

Pathogenic mechanisms of how human parvovirus breaks self-tolerance

2017

It is known that viral infections can cause acute, chronic, and autoimmune diseases (ADs). However, the mechanism of how a persistent viral infection contributes to ADs remains still unclear. In this thesis, pathological and immunological aspects of how common viruses can initiate autoimmunity were investigated, and human parvovirus B19 (B19V) was employed as a model virus. B19V non-structural protein 1 (NS1), a superfamily 3 (SF3) helicase, initiated DNA damage resulting in cellular apoptosis. The apoptotic bodies (ApoBods) induced by B19V NS1 were purified and characterized. These ApoBods contained viral NS1 proteins with modified autoimmune-associated self-antigens, e.g. DNA, Smith, Apol…

Cell biology of canine parvovirus entry

2003

Sanna Suikkasen väitöskirjatyössä havaittiin, että koiran parvovirus tarvitsee solun tarjoamaa kuljetuskoneistoa edetäkseen sen sisällä ja happamia olosuhteita pystyäkseen lisääntymään. Tulokset antavat kehykset viruksen ja sen läheisten sukulaisten solunsisäisen reitin tarkemmalle tutkimukselle ja luovat pohjaa viruslääkkeiden suunnitteluun. Mielenkiintoa parvoviruksien tutkimukseen lisää tutkijan mielestä myös kiinnostus parvopartikkeleiden geeniterapiasovellutuksiin. Koiran parvovirus eriytyi kissan panleukopeniaviruksesta 1970-luvun lopulla ja levisi nopeasti ympäri maailmaa. Se aiheuttaa aikuisille koirille ankaraa ripulia ja pennuille tappavia sydänlihastulehduksia. Parvovirukset aihe…

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…

Zur Morphologie, Klinik und Immunpathologie der Virus B-Hepatitis im Säuglings- und Kindesalter

1980

In Abhangigkeit von der Funktion des Immunsystems reagiert der kindliche Organismus nach einer Hepatitis Virus B-Infektion mit einem breiten Spektrum von verschiedenen HB s Ag-positiven Lebererkrankungen. Wahrend eine normale Immunantwort mit einer Elimination des Hepatitis B-Virus und seiner assoziierten Antigene einhergeht, fuhrt eine inadaquate Immunreaktivitat zu einer Virus- und/oder Antigenpersistenz im Serum und Lebergewebe.

Modelling the removal and reversible immobilization of murine noroviruses in a Phaeozem under various contamination and rinsing conditions

2018

International audience; Enteric viruses entering the soil with contaminated irrigation water can reach groundwater or be internalized in plants through their roots without being inactivated. Their fate in the soil depends on the virus, the soil and the soil solution. In order to write a mathematical model suitable for a Calcaric Phaeozem, we investigated the removal of murine norovirus and reversible immobilization in aggregate columns according to a saturation procedure, conditions between contamination and rinsing time, temperature and soil solution. Viruses were quantified before and after 0.45‐μm filtration with an RT‐qPCR (real‐time polymerase chain reaction). Experimental results supp…
