Identification of genes required for host-cell adhesion and antibiotic persistence of uropathogenic Escherichia coli via high-content screening

Thomas Marie Simonet

Uropathogenic Escherichia coli (UPEC) are the most common bacterial pathogens causing urinary tract infections (UTIs). Driven by the development of antibiotic resistant UPEC strains, UTIs have become a major public health issue and generate substantial hea ...

Invasive Streptococcal Infection Can Lead to the Generation of Cross-Strain Opsonic Antibodies

Hamed Khakzad

The bacterium Streptococcus pyogenes is a common cause of both mild and severe human diseases resulting in substantial morbidity and mortality each year. No vaccines are available, and our understanding of the antibody response to this human pathogen is st ...

A Manganese Phosphate Nanocluster Activates the cGAS‐STING Pathway for Enhanced Cancer Immunotherapy

Li Tang, Yugang Guo, Armand Kurum, Kewen Lei, Yuqing Xie, Min Gao, Yu Zhao, Xiaomeng Hu

Targeting the stimulator of interferon genes (STING) pathway with cyclic dinucleotides (CDNs), the natural STING agonists, is a promising immunotherapeutic strategy for cancer. However, the clinical application of natural CDNs as therapeutics is greatly hi ...

Cell-autonomous inflammation of BRCA1-deficient ovarian cancers drives both tumor-intrinsic immunoreactivity and immune resistance via STING

George Coukos, Christian Iseli, Alexandre Harari, Alizée Jéléna Grimm, Julien Dorier, Mauro Delorenzi

In this study, we investigate mechanisms leading to inflammation and immunoreactivity in ovarian tumors with homologous recombination deficiency (HRD). BRCA1 loss is found to lead to transcriptional reprogramming in tumor cells and cell-intrinsic inflammat ...

New Stable Cell Lines Derived from the Proximal and Distal Intestine of Rainbow Trout (Oncorhynchus mykiss) Retain Several Properties Observed In Vivo

Kristin Schirmer

We derived two novel cell lines from rainbow trout (RT) proximal (RTpi-MI) and distal intestine (RTdi-MI) and compared them with the previously established continuous cell line RTgutGC. Intestinal stem cells, differentiating and differentiated epithelial c ...

Akt Is S-Palmitoylated: A New Layer of Regulation for Akt

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami

The protein kinase Akt/PKB participates in a great variety of processes, including translation, cell proliferation and survival, as well as malignant transformation and viral infection. In the last few years, novel Akt posttranslational modifications have ...

Boosted Pro-Inflammatory Activity in Human PBMCs by Lipopolysaccharide and SARS-CoV-2 Spike Protein Is Regulated by alpha-1 Antitrypsin

Florian Maria Wurm, Divor Kiseljak

For the treatment of severe COVID-19, supplementation with human plasma-purified alpha-1 antitrypsin (AAT) to patients is currently considered. AAT inhibits host proteases that facilitate viral entry and possesses broad anti-inflammatory and immunomodulato ...

Multipotent mesenchymal stromal cells derived from porcine exocrine pancreas improve insulin secretion from juvenile porcine islet cell clusters

Sandrine Gerber, Luca Szabó

Neonatal and juvenile porcine islet cell clusters (ICC) present an unlimited source for islet xenotransplantation to treat type 1 diabetes patients. We isolated ICC from pancreata of 14 days old juvenile piglets and characterized their maturation by immuno ...

A secreted factor NimrodB4 promotes the elimination of apoptotic corpses by phagocytes in Drosophila

Bruno Lemaitre, Florent François Masson, Samuel Rommelaere, Elodie Julie Virginie Ramond, Bianca Marie Petrignani

Programmed cell death plays a fundamental role in development and tissue homeostasis. Professional and non-professional phagocytes achieve the proper recognition, uptake, and degradation of apoptotic cells, a process called efferocytosis. Failure in effero ...

Niche-Mediated Integrin Signaling Supports Steady-State Hematopoiesis in the Spleen

Jörg Hülsken

Outside-in integrin signaling regulates cell fate decisions in a variety of cell types, including hematopoietic stem cells (HSCs). Our earlier published studies showed that interruption of periostin (POSTN) and integrin-av (ITGAV) interaction induces faste ...

Molecular profiling and functional analysis of macrophage-derived tumour extracellular vesicles

Tim Beltraminelli

Extracellular vesicles (EVs) are nanosized vesicles released by virtually all cell types. Increasing data suggest that EVs function in the regulation of intercellular communication both in physiological and pathological states. In cancer biology, mounting ...

Neutrophils suppress tumor-infiltrating T cells in colon cancer via matrix metalloproteinase-mediated activation of TGF beta

Freddy Radtke, Mauro Delorenzi, George Coukos, Nadine Fournier, Marc-Olivier Sauvain, Amber Dawn Bowler, Markus Germann

High T-cell infiltration in colorectal cancer (CRC) correlates with a favorable disease outcome and immunotherapy response. This, however, is only observed in a small subset of CRC patients. A better understanding of the factors influencing tumor T-cell re ...
