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

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

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 ...

Activin-A impairs CD8 T cell-mediated immunity and immune checkpoint therapy response in melanoma

Daniel Constam, Etienne Meylan, Julien Robert Rémi Faget, Olivier Andreas Dubey, Katarina Pinjusic

Background Activin-A, a transforming growth factor beta family member, is secreted by many cancer types and is often associated with poor disease prognosis. Previous studies have shown that Activin-A expression can promote cancer progression and reduce the ...

Anti-Ly6G binding and trafficking mediate positive neutrophil selection to unleash the anti-tumor efficacy of radiation therapy

Caroline Anne-Lyse Contat, Etienne Meylan, Gael Luis Boivin, Pierre-Benoit Bernard Ancey

The anti-Ly6G antibody is used to deplete Ly6G(pos) neutrophils and study their role in diverse pathologies. However, depletion is never absolute, as Ly6G(low) neutrophils resistant to depletion rapidly emerge. Studying the functionality of these residual ...

GLUT1 Expression in Tumor-Associated Neutrophils Promotes Lung Cancer Growth and Resistance to Radiotherapy

Nadine Fournier, Caroline Anne-Lyse Contat, Etienne Meylan, Justine Pascual, Gael Luis Boivin, Pierre-Benoit Bernard Ancey, Silvia Sabatino

Neutrophils are the most abundant circulating leucocytes and are essential for innate immunity. In cancer, pro- or antitumor properties have been attributed to tumor-associated neutrophils (TAN). Here, focusing on TAN accumulation within lung tumors, we id ...

Overcoming microenvironmental resistance to PD-1 blockade in genetically engineered lung cancer models

Ioanna Keklikoglou, Nadine Fournier, Sina Nassiri, Etienne Meylan, Michele De Palma, Ece Kadioglu, Chiara Cianciaruso, Bruno Torchia, Gael Luis Boivin, Alan Nicolas Thierry Guichard, Amaia Martinez Usatorre

Immune checkpoint blockade (ICB) with PD-1 or PD-L1 antibodies has been approved for the treatment of nonsmall cell lung cancer (NSCLC). However, only a minority of patients respond, and sustained remissions are rare. Both chemotherapy and antiangiogenic d ...

Neutrophils in the era of immune checkpoint blockade

Etienne Meylan, Julien Robert Rémi Faget

The immune checkpoint blockade-based immunotherapies are revolutionizing cancer management. Tumor-associated neutrophils (TANs) were recently highlighted to have a pivotal role in modulating the tumor microenvironment and the antitumor immune response. How ...

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, Maxime Reichenbach, 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 ...

CD36-mediated metabolic adaptation supports regulatory T cell survival and function in tumors

Etienne Meylan, Fabien Franco

Depleting regulatory T cells (T-reg cells) to counteract immunosuppressive features of the tumor microenvironment (TME) is an attractive strategy for cancer treatment; however, autoimmunity due to systemic impairment of their suppressive function limits it ...

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' ...

Durable and controlled depletion of neutrophils in mice

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

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 ...

Tumour exosomal CEMIP protein promotes cancer cell colonization in brain metastasis

Gonçalo Rodrigues, Etienne Meylan, Loïc Steiner, Yuan Liu

The development of effective therapies against brain metastasis is currently hindered by limitations in our understanding of the molecular mechanisms driving it. Here we define the contributions of tumour-secreted exosomes to brain metastatic colonization ...
