Targeting the aging of tumor-associated neutrophils in lung cancer

Neutrophils are leukocytes that play a key role in innate immunity. Their mode of action in case of infection is well described, but their impact in different chronic diseases, such as cancer, remains unclear. Nevertheless, recent publications describe neu ...

Bcl-xL targeting eliminates ageing tumor-promoting neutrophils and inhibits lung tumor growth

Freddy Radtke, Etienne Meylan, Nadine Fournier, Amber Dawn Bowler, Justine Pascual, Anita Bodac

Elevated peripheral blood and tumor-infiltrating neutrophils are often associated with a poor patient prognosis. However, therapeutic strategies to target these cells are difficult to implement due to the life-threatening risk of neutropenia. In a genetica ...

Durable and controlled depletion of neutrophils in mice

Etienne Meylan, Julien Robert Rémi Faget, Gael Luis Boivin, Caroline Anne-Lyse Contat, Aspasia Gkasti, Pierre-Benoit Bernard Ancey, Justine Pascual, Jessica Christine Vazquez

Neutrophils are an essential part of the innate immune system. To study their importance, experimental studies often aim to deplete these cells, generally by injecting anti-Ly6G or anti-Gr1 antibodies. However, these approaches are only partially effective ...

Hookworms Evade Host Immunity by Secreting a Deoxyribonuclease to Degrade Neutrophil Extracellular Traps

Nicola Harris, Romain Guiet, Arne Seitz, Beatrice Volpe, Tiffany Babette Angélique Bouchery, Kathleen Shah, Mati André Marie Moyat, Manuel Kulagin

Hookworms cause a major neglected tropical disease, occurring after larvae penetrate the host skin. Neutrophils are phagocytes that kill large pathogens by releasing neutrophil extracellular traps (NETs), but whether they target hookworms during skin infec ...

Human proteinase 3 resistance to inhibition extends to alpha-2 macroglobulin

Marc Moniatte

Polymorphonuclear neutrophils contain at least four serine endopeptidases, namely neutrophil elastase (NE), proteinase 3 (PR3), cathepsin G (CatG), and NSP4, which contribute to the regulation of infection and of inflammatory processes. In physiological co ...

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 ...

Tumor-Promoting Ly-6G(+) SiglecF(high) Cells Are Mature and Long-Lived Neutrophils

Etienne Meylan

Myeloid cells co-expressing the markers CD11b, Ly-6G, and SiglecF can be found in large numbers in murine lung adenocarcinomas and accelerate cancer growth by fostering tumor cell invasion, angiogenesis, and immunosuppression; however, some of these cells' ...

Neutrophils and Snail Orchestrate the Establishment of a Pro-tumor Microenvironment in Lung Cancer

Nicolas Jean Philippe Guex, Etienne Meylan, Nadine Fournier, Alessandra Piersigilli, Julien Robert Rémi Faget, Miguel Garcia, Gael Luis Boivin, Svenja Johanna Groeneveld

Understanding the immune compartment of tumors facilitates the development of revolutionary new therapies. We used a Kras(G12D)-driven mouse model of lung cancer to establish an immune signature and identified a contribution of Gr1 + neutrophils to disease ...

Osteoblasts remotely supply lung tumors with cancer-promoting SiglecF(high) neutrophils

Etienne Meylan, Julien Robert Rémi Faget

Bone marrow-derived myeloid cells can accumulate within tumors and foster cancer outgrowth. Local immune-neoplastic interactions have been intensively investigated, but the contribution of the systemic host environment to tumor growth remains poorly unders ...

Increased Myeloid Cell Production and Lung Bacterial Clearance in Mice Exposed to Cigarette Smoke

Alessandra Piersigilli

Pneumonia is a leading cause of hospitalization in patients with chronic obstructive pulmonary disease (COPD). Although most patients with COPD are smokers, the effects of cigarette smoke exposure on clearance of lung bacterial pathogens and on immune and ...

Treatment with the GPR55 antagonist CID16020046 increases neutrophil activation in mouse atherogenesis

Nikolaos Stergiopoulos

Endocannabinoids modulate atherogenesis by triggering different receptors. Recently, orphan G protein-coupled receptors (GPRs) were suggested to be activated by endocannabinoids, possibly regulating vasorelaxation. Here, we investigated whether GPR55 antag ...

Biocompatible Packagings for Fully Implantable Multi-Panel Devices for Remote Monitoring of Metabolism

Giovanni De Micheli, Sandro Carrara, Camilla Baj-Rossi, Andrea Cavallini, Francesco Grassi

This paper compares three different biocompatible packagings suitable to support full implantation of multi-panel sensors for remote monitoring of metabolism. The three packagings have been designed, realized and implanted in mice for 30 days. ATP and neut ...
