HIV-1 Env Associates with HLA-C Free-Chains at the Cell Membrane
www.nature.com/scientificreports OPEN HIV-1 Env associates with HLA-C free-chains at the cell membrane modulating viral infectivity Received: 11 July 2016 Michela Serena1, Francesca Parolini1, Priscilla Biswas2, Francesca Sironi2, Accepted: 30 November 2016 Almudena Blanco Miranda1, Elisa Zoratti3, Maria Teresa Scupoli3, Serena Ziglio1,4, Published: 04 January 2017 Agustin Valenzuela-Fernandez4, Davide Gibellini5, Maria Grazia Romanelli1, Antonio Siccardi2, Mauro Malnati2, Alberto Beretta2 & Donato Zipeto1 HLA-C has been demonstrated to associate with HIV-1 envelope glycoprotein (Env). Virions lacking HLA-C have reduced infectivity and increased susceptibility to neutralizing antibodies. Like all others MHC-I molecules, HLA-C requires β2-microglobulin (β2m) for appropriate folding and expression on the cell membrane but this association is weaker, thus generating HLA-C free-chains on the cell surface. In this study, we deepen the understanding of HLA-C and Env association by showing that HIV-1 specifically increases the amount of HLA-C free chains, not bound toβ 2m, on the membrane of infected cells. The association between Env and HLA-C takes place at the cell membrane requiring β2m to occur. We report that the enhanced infectivity conferred to HIV-1 by HLA-C specifically involves HLA-C free chain molecules that have been correctly assembled with β2m. HIV-1 Env-pseudotyped viruses produced in the absence of β2m are less infectious than those produced in the presence of β2m. We hypothesize that the conformation and surface expression of HLA-C molecules could be a discriminant for the association with Env. Binding stability to β2m may confer to HLA-C the ability to preferentially act either as a conventional immune-competent molecule or as an accessory molecule involved in HIV-1 infectivity. -

Scientific Report 2012 Institute for Research in Biomedicine Scientific Report 2012
Università Institute for della Research in Svizzera Biomedicine italiana Institute for Research in Biomedicine Scientific Report 2012 Institute for Research in Biomedicine Scientific Report 2012 This Scientific Report covers the 2012 Research Activities of the Institute for Research in Biomedicine (IRB) The report can also be accessed at the IRB's website www.irb.usi.ch Scientific Report 2012 Foreword by Giorgio Noseda and Gabriele Gendotti Past and Present Presidents of the Foundation Council The Institute for Research in Biomedicine (IRB), a university-level research institute, has already well af- firmed itself worldwide, despite having started its operations only in the year 2000. Its key strengths are a leadership of international fame, a network of excellent collaborations, and an environment that allows for the carrying out of research with limited teaching activity. 2012 was a year rich in events for the IRB. We in fact modified the Foundation Board and elected a new President to make room for new strengths and fresh ideas and to better face the future challenges that we have undertaken for the growth of the IRB. The Presidential transition and the approval of the new Founda- tion Board of the IRB took place on June 25th, 2012, and were followed by a meeting with the Bellinzona township authorities in which notable scientific results as well as the prospects of expansion of the Institute were presented. The Foundation Board has also finalized a document that describes its future strategies, its mission, its vision, its goals and the predicted evolution of the IRB for the period from 2012 to 2016. -
