CD36-mediated metabolic adaptation supports regulatory T cell survival and function in tumors

Depleting regulatory T cells (T-reg cells) to counteract immunosuppressive features of the tumor microenvironment (TME) is an attractive strategy for cancer treatment; however, autoimmunity due to systemic impairment of their suppressive function limits it ...

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

Xavier Fredy René Quaglia-Thermes, Giacomo Olimpio Diaceri, Jeffrey Alan Hubbell, Sachiko Hirosue, 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 ...

Single-Virus Droplet Microfluidics for High-Throughput Screening of Neutralizing Epitopes on HIV Particles

Christoph Merten

Analyzing surface epitopes of single HIV particles holds great potential for the development of vaccine candidates. However, existing technologies do not allow corresponding screens at high throughput. We present here a single-virus droplet-based microflui ...

Investigating the Biological Mechanisms underlying the Initiation of Autoimmunity against Beta Cell Antigens in Type 1 Diabetes

Chiara Cianciaruso

Type 1 diabetes (T1D) is an autoimmune disease characterized by circulating autoantibodies, lymphocytic infiltration of pancreatic islets of Langerhans, and cell-specific destruction of beta cells, leading to insulin deficiency and symptomatic hyperglycemi ...

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 ...

Amyloid-beta oligomerization is associated with the generation of a typical peptide fragment fingerprint

Davide Demurtas, Marc Moniatte, Adrian Schmid, Cyntia De Piano, Nikita Rudinskiy, Christophe Fuerer

Amyloid-beta (A beta) peptide oligomerization plays a central role in the pathogenesis of Alzheimer's disease (AD), and A beta oligomers are collectively considered an appealing therapeutic target for the treatment of AD. However, the molecular mechanisms ...

Aberrant Accumulation of the Diabetes Autoantigen GAD65 in Golgi Membranes in Conditions of ER Stress and Autoimmunity

Jeffrey Alan Hubbell, Steinunn Baekkeskov Hanahan, Chiara Cianciaruso, Miriella Carmela Pasquier, Edward Allen Phelps

Pancreatic islet β-cells are particularly susceptible to endoplasmic reticulum (ER) stress, which is implicated in β-cell dysfunction and loss during the pathogenesis of type 1 diabetes (T1D). The peripheral membrane protein GAD65 is an autoantigen in huma ...
