Engineering Agrobacterium tumefaciens Adhesion to Target Cells

Alexandre Louis André Persat, Xavier Jean-Yves Pierrat, Jeremy Pak Hei Wong, Alix Kim Lan Pham

Agrobacterium tumefaciens is a plant pathogen commonly repurposed for genetic modification of crops. Despite its versatility, it remains inefficient at transferring DNA to many hosts, including to animal cells. Like many pathogens, physical contact between ...

Tumor-specific cytolytic CD4 T cells mediate immunity against human cancer

Hatice Altug, Alexander Mathis, George Coukos, Xiaokang Li, Yen-Cheng Liu, David Gfeller, Pedro Romero, Alexandre Harari, Amélie Cachot, Margaux Saillard, Georg Alexander Rockinger

CD4 T cells have been implicated in cancer immunity for their helper functions. Moreover, their direct cytotoxic potential has been shown in some patients with cancer. Here, by mining single-cell RNA-seq datasets, we identified CD4 T cell clusters displayi ...

Noninvasive rapid detection of metabolic adaptation in activated human T lymphocytes by hyperpolarized 13C magnetic resonance

Mor-Miri Mishkovsky, Arnaud Comment, Hikari Ananda Infinity Yoshihara, Nicolas Kunz, Emine Can

The metabolic shift induced in human CD4+ T lymphocytes by stimulation is characterized by an upregulation of glycolysis, leading to an augmentation in lactate production. This adaptation has already been highlighted with various techniques and reported in ...

Structure and Function of the T4 Spackle Protein Gp61.3

Petr Leiman, Alec Fraser

The bacteriophage T4 genome contains two genes that code for proteins with lysozyme activity-e and 5. Gene e encodes the well-known T4 lysozyme (commonly called T4L) that functions to break the peptidoglycan layer late in the infection cycle, which is requ ...

The metabolite BH4 controls T cell proliferation in autoimmunity and cancer

Kai Johnsson, Jairo Alexander Lozano Moreno, Yann Mathieu Pierson

Genetic regulators and environmental stimuli modulate T cell activation in autoimmunity and cancer. The enzyme co-factor tetrahydrobiopterin (BH4) is involved in the production of monoamine neurotransmitters, the generation of nitric oxide, and pain(1,2). ...

Differential immunodominance hierarchy of CD8+ T cell responses in HLA-B27:05 and B27:02-mediated control of HIV-1 infection

Jacques Fellay

The well-characterised association between HLA-B27:05 and protection against HIV disease progression has been linked to immunodominant HLA-B27:05-restricted CD8+ T-cell responses towards the conserved Gag 263-272 ('KK10') and Pol 901-909 'KY9' epitopes. ...

New roles of the lymphatic endothelium in modulating adaptive immunity: implications for immune tolerance and cancer immunotherapy

Lambert Charles François Potin

Lymphatic vessels have traditionally been considered as passive conduits for interstitial fluid drainage and for immune cell trafficking to lymph nodes. In the last two decades, many studies have challenged this classical dogma: lymphatic endothelial cells ...

Introducing tolerance to foreign and partly foreign proteins by erythrocyte binding and artificial glycosylations

Kym Lorenz Brünggel

Over the last few years, protein drugs have steadily gained importance in the clinic. Compared to small molecule drugs, protein drugs are taken up by antigen presenting cells, which degrade the proteins into peptides that are then presented on major histoc ...

T cell–induced CSF1 promotes melanoma resistance to PD1 blockade

Michele De Palma, George Coukos, Krisztian Homicsko, Sina Nassiri, Natacha Anne-Sophie Bordry, Esther Danenberg, Laure Tillé, Christophe Martignier

Colony-stimulating factor 1 (CSF1) is a key regulator of monocyte/macrophage differentiation that sustains the protumorigenic functions of tumor-associated macrophages (TAMs). We show that CSF1 is expressed in human melanoma, and patients with metastatic m ...

Development of a nano-adjuvant cancer vaccine and its evaluation for melanoma in combination with radiotherapy

Sylvie Hauert

Cancer is the second leading cause of death in the world and melanoma is the deadliest type of skin cancer. Although surgery, radiotherapy and chemotherapy are still standard treatments, the discovery of the role played by the immune system in cancer has a ...

Nanoparticle Conjugation of Human Papillomavirus 16 E7-long Peptides Enhances Therapeutic Vaccine Efficacy against Solid Tumors in Mice

Douglas Hanahan, Mélanie Louise Tichet, Melody Swartz, Stephan Wullschleger, Gabriele Galliverti, Sylvie Hauert

Treatment of patients bearing human papillomavirus (HPV)-related cancers with synthetic long-peptide (SLP) therapeutic vaccines has shown promising results in clinical trials against premalignant lesions, whereas responses against later stage carcinomas ha ...

Absence of specific alternatively spliced exon of CD44 in macrophages prevents colitis

Ulrich Hoffmann, Riccardo Sabatini

CD44 is a transmembrane molecule appearing in numerous isoforms generated by insertions of alternatively spliced variant exons (CD44v) and having various binding partners. CD44v7 on T cells was proposed to promote colitis by preventing T-cell apoptosis. He ...

Bimodal CD40/Fas-Dependent Crosstalk between iNKT Cells and Tumor-Associated Macrophages Impairs Prostate Cancer Progression

Michele De Palma, Ferdinando Pucci, Alessandra Recchia

Heterotypic cellular and molecular interactions in the tumor microenvironment (TME) control cancer progression. Here, we show that CD1d-restricted invariant natural killer (iNKT) cells control prostate cancer (PCa) progression by sculpting the TME. In a mo ...
