Early-life vitamin A treatment rescues neonatal infection-induced durably impaired tolerogenic properties of celiac lymph nodes

Jörn Pezoldt

Gut -draining mesenteric and celiac lymph nodes (mLNs and celLNs) critically contribute to peripheral tolerance toward food and microbial antigens by supporting the de novo induction of regulatory T cells (Tregs). These tolerogenic properties of mLNs and c ...

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 ...

Preliminary evidence that daily light exposure enhances the antibody response to influenza vaccination in patients with dementia

Jean-Louis Scartezzini

Enhancing lighting conditions in institutions for individuals with dementia improves their sleep, circadian rhythms and well-being. Here, we report first findings that exposure to brighter light during daytime may support the immune response to the annual ...

A Rapid Translational Immune Response Program in CD8 Memory T Lymphocytes

Linlin Cao

The activation of memory T cells is a very rapid and concerted cellular response that requires coordination between cellular processes in different compartments and on different time scales. In this study, we use ribosome profiling and deep RNA sequencing ...

Interplay of cGAS with chromatin

Andrea Ablasser, Marilena Wischnewski

Recognition of DNA is an evolutionarily highly conserved mechanism of immunity. In mammals, the cGAS-STING pathway plays a central role in coupling DNA sensing to the execution of innate immune mechanisms, both in contexts of infection as well as in noninf ...

A Nanoscaffolded Spike-RBD Vaccine Provides Protection against SARS-CoV-2 with Minimal Anti-Scaffold Response

Bruno Emanuel Ferreira De Sousa Correia, David Hacker, Florence Pojer, Kelvin Ka Ching Lau

The response of the adaptive immune system is augmented by multimeric presentation of a specific antigen, resembling viral particles. Several vaccines have been designed based on natural or designed protein scaffolds, which exhibited a potent adaptive immu ...

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

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 ...

BAF restricts cGAS on nuclear DNA to prevent innate immune activation

Beat Fierz, Mahmut Selman Sakar, Andrea Ablasser, Murat Kaynak, Kristina Makasheva, Alexiane Clara Decout, Baptiste Claude André Guey, Marilena Wischnewski

The appearance of DNA in the cytosol is perceived as a danger signal that stimulates potent immune responses through cyclic guanosine monophosphate–adenosine monophosphate synthase (cGAS). How cells regulate the activity of cGAS toward self-DNA and guard a ...

The orphan nuclear receptor LRH-1/NR5a2 critically regulates T cell functions

Kristina Schoonjans

LRH-1 (liver receptor homolog-1/NR5a2) is an orphan nuclear receptor, which regulates glucose and lipid metabolism, as well as intestinal inflammation via the transcriptional control of intestinal glucocorticoid synthesis. Predominantly expressed in epithe ...

Nucleic acids presenting polymer nanomaterials as vaccine adjuvants

Maartje Martina Cornelia Bastings, Alice Comberlato, Kaltrina Paloja

Most vaccines developed today include only the antigens that best stimulate the immune system rather than the entire virus or microbe, which makes vaccine production and use safer and easier, though they lack potency to induce acceptable immunity and long- ...

The era of bioengineering: how will this affect the next generation of cancer immunotherapy?

Harm-Anton Klok, Cristiana Berti, Michele Graciotti

Background: Immunotherapy consists of activating the patient's immune system to fight cancer and has the great potential of preventing future relapses thanks to immunological memory. A great variety of strategies have emerged to harness the immune system a ...
