HLA tapasin independence: broader peptide repertoire and HIV control

Jacques Fellay

Human leukocyte antigen (HLA) class I allotypes vary in their ability to present peptides in the absence of tapasin, an essential component of the peptide loading complex. We quantified tapasin dependence of all allotypes that are common in European and Af ...

Standardization and Validation of Fluorescence-Based Quantitative Assay to Study Human Platelet Adhesion to Extracellular-Matrix in a 384-Well Plate

Nikolaos Stergiopoulos, Augusto Martins Lima, François Cuenot

Platelets play a crucial role in the immunological response and are involved in the pathological settings of vascular diseases, and their adhesion to the extracellular matrix is important to bring leukocytes close to the endothelial cells and to form and s ...

A computationally designed chimeric antigen receptor provides a small-molecule safety switch for T-cell therapy

Bruno Emanuel Ferreira De Sousa Correia, George Coukos, Jaume Bonet Martinez, Pablo Gainza Cirauqui, Sailan Shui, Sabrina Susan Vollers

The activity of CAR-T cells is reversibly halted with a small-molecule drug. Approaches to increase the activity of chimeric antigen receptor (CAR)-T cells against solid tumors may also increase the risk of toxicity and other side effects. To improve the s ...

Atomic-Scale Description of Interfaces between Antigen and Aluminum-Based Adjuvants Used in Vaccines by Dynamic Nuclear Polarization (DNP) Enhanced NMR Spectroscopy

Federico Maria Paruzzo, Jasmine Viger-Gravel

The addition of aluminum-based adjuvants in vaccines enhances the immune response to antigens. The strength of antigen adsorption on adjuvant gels is known to modulate vaccine efficacy. However, a detailed understanding of the mechanisms of interaction bet ...

Cathepsin S Regulates Antigen Processing and T Cell Activity in Non-Hodgkin Lymphoma

Bruno Emanuel Ferreira De Sousa Correia, George Coukos, Elisa Oricchio, Julien Racle, Sarah Wehrle, Elena Battistello, Jessica Sordet, Natalya Katanayeva, Stephanie Jocelyne Sungalee, Elie Charles Eugène Dheilly

Genomic alterations in cancer cells can influence the immune system to favor tumor growth. In non-Hodgkin lymphoma, physiological interactions between B cells and the germinal center microenvironment are coopted to sustain cancer cell proliferation. We fou ...

Myeloid Cells Orchestrate Systemic Immunosuppression, Impairing the Efficacy of Immunotherapy against HPV+ Cancers

Melody Swartz, Douglas Hanahan, Nadine Fournier, Mélanie Louise Tichet, Stephan Wullschleger, Gabriele Galliverti

Cancers induced by human papillomaviruses (HPV) should be responsive to immunotherapy by virtue of expressing the immunogenic oncoproteins E6/E7. However, advanced forms of cervical cancer, driven by HPV, are poorly responsive to immune response-enhancing ...

Inborn errors of type I IFN immunity in patients with life-threatening COVID-19

Jacques Fellay

Clinical outcome upon infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ranges from silent infection to lethal coronavirus disease 2019 (COVID-19). We have found an enrichment in rare variants predicted to be loss-of-function (LOF ...

Functional de novo Protein Design for Targeted Vaccines and Synthetic Biology Applications

Che Yang

Evolution has created, selected and evolved large repertoires of proteins that operate in various biological systems. Nowadays biotechnological needs are coming up orders of magnitude faster than proteins naturally evolve. The emergence of de novo protein ...

Rationally designed Human Cytomegalovirus gB nanoparticle vaccine with improved immunogenicity

Davide Demurtas

Author summary Human cytomegalovirus (HCMV) infection is the foremost viral cause of congenital birth defects. Attempts to vaccinate against HCMV brought moderate, though not sufficient, reduction in infection. Moreover, phase II clinical trial with gB for ...

HIV Transmission Chains Exhibit Greater HLA-B Homogeneity Than Randomly Expected

Jacques Fellay, Christian Axel Wandall Thorball

Background: HIV's capacity to escape immune recognition by human leukocyte antigen (HLA) is a core component of HIV pathogenesis. A better understanding of the distribution of HLA class I in HIV-infected patients would improve our knowledge of pathogenesis ...

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

Jacques Fellay, Paul Jack Mc Laren, Nimisha Chaturvedi

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 ...

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 ...
