A common NFKB1 variant detected through antibody analysis in UK Biobank predicts risk of infection and allergy

Jacques Fellay, Flavia Aurelia Shoko Hodel

Infectious agents contribute significantly to the global burden of diseases through both acute infection and their chronic sequelae. We leveraged the UK Biobank to identify genetic loci that influence humoral immune response to multiple infections. From 45 ...

Microfluidic characterisation reveals broad range of SARS-CoV-2 antibody affinity in human plasma

Didier Trono, Priscilla Turelli, Marc Emmenegger

The clinical outcome of SARS-CoV-2 infections, which can range from asymptomatic to lethal, is crucially shaped by the concentration of antiviral antibodies and by their affinity to their targets. However, the affinity of polyclonal antibody responses in p ...

Primary data for EPFL thesis "Metabolic regulation of cytokinesis in Schizosaccharomyces pombe"

Özge Uysal Özdemir

All cells need to be able to sense their environment, and adapt their metabolism, growth and cell division appropriately. In this study, I examined the response of Schizosaccharomyces pombe to a change in the carbon source and how that affects cytokinesis. ...

Modeling Immunity with Rosetta: Methods for Antibody and Antigen Design

Bruno Emanuel Ferreira De Sousa Correia, Jaume Bonet Martinez

Structure-based antibody and antigen design has advanced greatly in recent years, due not only to the increasing availability of experimentally determined structures but also to improved computational methods for both prediction and design. Constant improv ...

Regulatory T cells engineered with TCR signaling-responsive IL-2 nanogels suppress alloimmunity in sites of antigen encounter

Li Tang, Na Li

Adoptive cell transfer of ex vivo expanded regulatory T cells (T-r(egs)) has shown immense potential in animal models of auto- and alloimmunity. However, the effective translation of such T-reg therapies to the clinic has been slow. Because T-reg homeostas ...

Low-dose photodynamic therapy promotes a cytotoxic immunological response in a murine model of pleural mesothelioma

Paul Joseph Dyson, Etienne Meylan, Julien Robert Rémi Faget, Aspasia Gkasti, Yameng Hao, Maxime Reichenbach

OBJECTIVES: Malignant pleural mesothelioma (MPM) is a deadly disease with limited treatment options. Approaches to enhance patient immunity against MPM have been tested but shown variable results. Previously, we have demonstrated interesting vascular modul ...

HIV peptidome-wide association study reveals patient-specific epitope repertoires associated with HIV control

Jacques Fellay, Nimisha Chaturvedi, Paul Jack Mc Laren

Genetic variation in the peptide-binding groove of the highly polymorphic HLA class I molecules has repeatedly been associated with HIV-1 control and progression to AIDS, accounting for up to 12% of the variation in HIV-1 set point viral load (spVL). This ...

HLA-B*14:02-Restricted Env-Specific CD8+ T-Cell Activity Has Highly Potent Antiviral Efficacy Associated with Immune Control of HIV Infection

Jacques Fellay

Immune control of human immunodeficiency virus type 1 (HIV) infection is typically associated with effective Gag-specific CD8+ T-cell responses. We here focus on HLA-B14, which protects against HIV disease progression, but the immunodominant HLA-B14-rest ...

Protein engineering approaches for direct antigen targeting in CD8+ T cell inducing vaccines

Vasiliki Panagiotou

Effective vaccine design and public vaccination programs have led to the eradication of several diseases and protected millions of people from deadly infections. However, intracellular infections remain a challenge and their eradication requires the activa ...

Memory of tolerance and induction of regulatory T cells by erythrocyte-targeted antigens

Jeffrey Alan Hubbell, Xavier Fredy René Quaglia-Thermes, Giacomo Olimpio Diaceri, Stephane Kontos, Alizée Jéléna Grimm

New approaches based on induction of antigen-specific immunological tolerance are being explored for treatment of autoimmunity and prevention of immunity to protein drugs. Antigens associated with apoptotic debris are known to be processed tolerogenically ...

Modes of antigen presentation by lymph node stromal cells and their immunological implications

Sachiko Hirosue

Antigen presentation is no longer the exclusive domain of cells of hematopoietic origin. Recent works have demonstrated that lymph node stromal cell (LNSC) populations, such as fibroblastic reticular cells, lymphatic and blood endothelial cells, not only p ...

Thymic stromal lymphopoietin plays divergent roles in murine models of atopic and nonatopic airway inflammation

Nicola Harris, Benjamin John Marsland, Ilaria Mosconi

BackgroundThymic stromal lymphopoietin (TSLP) is a cytokine primarily produced by epithelial cells, which has been shown to be a potent inducer of T-helper 2 (Th2)-type responses. However, TSLP has pleiotropic effects upon immune cells, and although extens ...

Gut homeostasis in a microbial world: insights from Drosophila melanogaster

Bruno Lemaitre, Nichole Broderick

Intestinal homeostasis is achieved, in part, by the integration of a complex set of mechanisms that eliminate pathogens and tolerate the indigenous microbiota. Drosophila melanogaster feeds on microorganism-enriched matter and therefore has developed effic ...

Immune Engineering Via Differential Antigen Carriers and Co-Stimulatory Molecules

Jackson Eby

There is an increasing clinical need for vaccines capable of enhancing antigen-specific immune responses and treatments that can induce immunological tolerance toward a single antigen. Here we explore two platforms to enhance either immunization or toleriz ...

Lymphatic drainage function and its immunological implications: From dendritic cell homing to vaccine design

Jeffrey Alan Hubbell, Melody Swartz, Sai Reddy

The slow interstitial flow that drains fluid from the blood capillaries into the lymphatic capillaries provides transport of macromolecular nutrients to cells in the interstitium. We discuss herein how this flow also provides continuous access to immune ce ...

Exploiting immunofunctional nanoparticles as vaccines and synthetic pathogens

Sai Reddy

The emergence of recombinant DNA technology has shifted research towards developing subunit vaccines, which use protein or peptide antigens instead of live/attenuated pathogens. Recent research has also shown that the best way to get sustained immunity is ...

Anti-cooperativity in diffusion-controlled reactions with pairs of anisotropic domains: a model for the antigen-antibody encounter

Paolo De Los Rios, Francesco Piazza

The encounter between anisotropic agents in diffusion-controlled reactions is a topic of very general relevance in chemistry and biology. Here we introduce a simplified model of encounter of an isotropic molecule with a pair of partially reacting agents an ...

Allogeneic beta-islet cells correct diabetes and resist immune rejection

Patrick Aebischer

Allogeneic MHC-incompatible organ or cell grafts are usually promptly rejected by immunocompetent hosts. Here we tested allogeneic beta-islet cell graft acceptance by immune or naive C57BL/6 mice rendered diabetic with streptozotocin (STZ). Fully MHC-misma ...
