Synthetically glycosylated antigens induce antigen-specific tolerance and prevent the onset of diabetes

Jeffrey Alan Hubbell, Sachiko Hirosue, Xavier Fredy René Quaglia-Thermes, Martina Damo, David Scott Wilson, Giacomo Olimpio Diaceri, Michal Mateusz Raczy

Homeostatic antigen presentation by hepatic antigen-presenting cells, which results in tolerogenic T-cell education, could be exploited to induce antigen-specific immunological tolerance. Here we show that antigens modified with polymeric forms of either N ...

Targeted antibody and cytokine cancer immunotherapies through collagen affinity

Jeffrey Alan Hubbell, Melody Swartz, Seung Tae Lee, Lambert Charles François Potin, Jun Ishihara, Kazuto Fukunaga, Michal Mateusz Raczy

Cancer immunotherapy with immune checkpoint inhibitors (CPIs) and interleukin-2 (IL-2) has demonstrated clinical efficacy but is frequently accompanied with severe adverse events caused by excessive and systemic immune system activation. Here, we addressed ...

Genetic determinants of healthy human immune variance: from humoral response to microbiome diversity

Petar Scepanovic

Identifying the drivers of the observed interindividual variability of the human immune system is crucial to our understanding of infectious and immune-mediated diseases. The contribution of genetic and non-genetic factors to immunological differences betw ...

Targeting cancer stem cells by T cell engineering

Nicolas Pierre Desbaillets

The identification of cancer stem cells (CSCs) has fundamentally changed the understanding of tumor biology. CSCs drive tumor initiation and long term tumor growth, can cause relapse and are essential for metastatic colonization. These features place cance ...

Mechanisms of tolerance induction by erythrocyte-targeted antigens

Alizée Jéléna Grimm

Immune-mediated disorders such as autoimmune diseases, graft-versus-host disease or allergies, are a major contemporary burden. Despite significant advances in the field of immunological tolerance, immunosuppressive drugs are still the current hallmark for ...

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 ...

Engineering antigen-specific immunological tolerance

Jeffrey Alan Hubbell, Stephane Kontos, Alizée Jéléna Grimm

Unwanted immunity develops in response to many protein drugs, in autoimmunity, in allergy, and in transplantation. Approaches to induce immunological tolerance aim to either prevent these responses or reverse them after they have already taken place. We pr ...

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

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

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 ...

Amino Acid Variation in HLA Class II Proteins Is a Major Determinant of Humoral Response to Common Viruses

Jacques Fellay, Istvan Bartha, Paul Jack Mc Laren, Christian Hammer

The magnitude of the human antibody response to viral antigens is highly variable. To explore the human genetic contribution to this variability, we performed genome-wide association studies of the immunoglobulin G response to 14 pathogenic viruses in 2,36 ...

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 ...
