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

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

Expanding beyond the natural protein repertoire to engineer targeted vaccines and diagnostics

Fabian Sesterhenn

Proteins have evolved over millions of years to carry out the vast majority of biological functions that are fundamental to life. Their three-dimensional structures and functions have been in the focus of biomedical research for many decades, and substanti ...

Structure-based immunogen design - leading the way to the new age of precision vaccines

Bruno Emanuel Ferreira De Sousa Correia, Jaume Bonet Martinez, Fabian Sesterhenn

Vaccines have been one of the most successful interventions in global health. However, traditional vaccine development has proven insufficient to deal with pathogens that elude the immune system through highly variable and non-functional epitopes. Emerging ...

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 ...

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 ...

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 ...

Comparative genomics of Esx genes from clinical isolates of Mycobacterium tuberculosis provides evidence for gene conversion and epitope variation

Stewart Cole, Swapna Uplekar, Jacques Rougemont

The 23-membered Esx protein family is involved in the host-pathogen interactions of Mycobacterium tuberculosis. These secreted proteins are among the most immunodominant antigens recognized by the human immune system and have thus been used to develop vacc ...
