Ison kiven ympärillä : koulutila ja oppilaat sen käyttäjinä Kuokkalan yläasteella

Tetraspanins (Tspans) are a family of four-span transmembrane proteins, known as plasma membrane “master organizers.” They form Tspan-enriched microdomains (TEMs or TERMs) through lateral association with one another and other membrane proteins. If multiple microdomains associate with each other, larger platforms can form. For infection, viruses interact with multiple cell surface components, including receptors, activating proteases, and signaling molecules. It appears that Tspans, such as CD151, CD82, CD81, CD63, CD9, Tspan9, and Tspan7, coordinate these associations by concentrating the interacting partners into Tspan platforms. In addition to mediating viral attachment and entry, these …
TLR7 controls VSV replication in CD169(+) SCS macrophages and associated viral neuroinvasion
2019
Vesicular stomatitis virus (VSV) is an insect-transmitted rhabdovirus that is neurovirulent in mice. Upon peripheral VSV infection, CD169+ subcapsular sinus (SCS) macrophages capture VSV in the lymph, support viral replication, and prevent CNS neuroinvasion. To date, the precise mechanisms controlling VSV infection in SCS macrophages remain incompletely understood. Here, we show that Toll-like receptor-7 (TLR7), the main sensing receptor for VSV, is central in controlling lymph-borne VSV infection. Following VSV skin infection, TLR7−/− mice display significantly less VSV titers in the draining lymph nodes (dLN) and viral replication is attenuated in SCS macrophages. In contrast to effects o…
INFECTIOUS COMPLICATIONS AFTER UMBILICAL CORD-BLOOD TRANSPLANTATION FROM UNRELATED DONORS
2016
Umbilical cord-blood (UCB) is a well-recognized alternative source of stem cells for unrelated donor hematopoietic stem cell transplantation (HSCT). As compared with other stem cell sources from adult donors, it has the advantages of immediate availability of cells, absence of risk to the donor and reduced risk of graft-versus-host disease despite donor-recipient HLA disparity. However, the use of UCB is limited by the delayed post-transplant hematologic recovery due, at least in part, to the reduced number of hematopoietic cells in the graft and the delayed or incomplete immune reconstitution. As a result, severe infectious complications continue to be a leading cause of morbidity and mort…
Article Commentary: Clinical Medicine: Endocrinology and Diabetes: Insulin Resistance–-a Link between Inflammation and Hepatocarcinogenesis?
2009
The incidence of hepatocellular carcinoma (HCC) is increasing world wide. The risk factors for the development of HCC include liver cirrhosis, chronic alcohol intake, and chronic viral hepatitis. These conditions are associated with inflammation, liver cell injury, and oxidative stress. The signaling pathways that contribute to liver cell injury have been shown to also promote insulin resistance in hepatocytes. On the other hand, obesity and diabetes have been suggested as risk factors for the development of chronic liver disease and HCC. The molecular mediators (e.g. stress kinases) and signaling pathways that contribute to cellular injury, proliferation and insulin resistance are also ac…

Multicompartmental Lipopolyplex as Vehicle for Antigens and Genes Delivery in Vaccine Formulations
2021
Vector design and its characterization is an area of great interest in current vaccine research. In this article, we have formulated and characterized a multicompartmental lipopolyplex, which associates multiple liposomes and polyplexes in the same complex. These particles allow the simultaneous delivery of lipid or water-soluble antigens associated with genes to the same cell, in much higher amounts than conventional lipopolyplexes. The vector characterization and optimization were carried out using liposomes with entrapped carboxyfluorescein and adapted electrophoretic assays. Two types of lipopolyplexes (containing hydrophilic or lipophilic antigens) were employed to evaluate their inter…
A multiresidue analytical method for trace level determination of antibiotics and antiretroviral drugs in wastewater and surface water using SPE-LC-M…
2016
An analytical method for simultaneous determination of seven commonly used antibiotics and three antiretrovirals in surface water and urban wastewater at the ng L−1 level has been developed. The method involves concentration and clean-up by solid phase extraction (SPE) followed by identification and quantification by liquid chromatography tandem mass spectrometry (LC-ESI-MS/MS). The use of matrix-matched calibration curves constructed by spiking surface water was evaluated for quantification and compared with the internal standard method using isotopically labelled compounds. The method gave absolute recoveries of 41–116% with most of the compounds having recoveries >50%. The LOQs ranged fr…
Suomenlinna etnografisen pitkittäistutkimuksen kohteena : esitutkimusvaihe tutkimusprosessin osana
2017
Artikkelissa tarkastellaan pitkittäistutkimukseen tähtäävän etnografisen kenttätyön esitutkimusvaihetta (2015–2016) Suomenlinnassa. Elävä Suomenlinna -tutkimuksen esitutkimusta ohjasi kiinnostus siihen, millaisia vaikutuksia Unescon maailmanperintöstatuksella on 25 vuoden aikana ollut paikallisten asukkaiden ja yhteisöjen elämään. Kansainväliset kulttuuriperintösopimukset korostavat yhteisöjen roolia kulttuuriperinnön suojelijoina, käyttäjinä ja eteenpäin välittäjinä. Tämä luo tarpeen suomenlinnalaisten paikkasuhdetta tarkastelevalle ajantasaiselle tutkimustiedolle. Erityisen kiinnostavaa on pohtia, millaisia tulokulmia paikallisilla on yhteisöllisyyteen, kulttuuriperintöön ja muuttuvaan el…
