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 ...

Targeting the aging of tumor-associated neutrophils in lung cancer

Anita Bodac

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 ...

Exploration and modulation of mechanical cues for enhanced cancer immunotherapy

Armand Kurum

The advent of immunotherapy, such as immune checkpoint blockade (ICB) and adoptive transfer of cytotoxic lymphocytes, has transformed the clinical care of cancer. However, a significant proportion of patients are resistant to immunotherapy or experience re ...

Bacterial diversity dominates variable macrophage responses of tuberculosis patients in Tanzania

Jacques Fellay, Zhi Ming Xu

The Mycobacterium tuberculosis complex (MTBC) comprises nine human-adapted lineages that differ in their geographical distribution. Local adaptation of specific MTBC genotypes to the respective human host population has been invoked in this context. We aim ...

Single-cell analysis of the interactions between Mycobacterium tuberculosis and macrophages

Ophélie Rutschmann

Mycobacterium Tuberculosis is a highly effective pathogen infecting nearly a third of the world's population. An M. tuberculosis infection starts when droplets containing bacteria enter an individual's lungs. The first host cells to contact the bacteria ar ...

Acute TNF alpha levels predict cognitive impairment 6-9 months after COVID-19 infection

Dimitri Nestor Alice Van De Ville, Alessandra Griffa, Idris Guessous, Alexandre Cionca

Background: A neurocognitive phenotype of post-COVID-19 infection has recently been described that is characterized by a lack of awareness of memory impairment (i.e., anosognosia), altered functional connectivity in the brain's default mode and limbic netw ...

Multivalent Virucidal Antivirals: Synthesis, Mechanisms of Action, and Immune-stimulating Effects

Yong Zhu

Viruses initiate invasion by binding to cell surface glycoproteins. Materials mimicking the carbohydrate motifs of these glycoproteins, such as heparan sulfate (HS) and sialic acid (SA) can block viral attachment and inhibit the infection. Multivalent disp ...

CSF-contacting neurons respond to Streptococcus pneumoniae and promote host survival during central nervous system infection

Ludovic Pierre Gustave Keiser

The pathogenic bacterium Streptococcus pneumoniae (S. pneumoniae) can invade the cerebrospinal fluid (CSF) and cause meningitis with devastating consequences. Whether and how sensory cells in the central nervous system (CNS) become activated during bacteri ...

Monocyte-derived macrophages aggravate pulmonary vasculitis via cGAS/STING/IFN-mediated nucleic acid sensing

Andrea Ablasser

Kessler et al. identify aberrant DNA recognition by cGAS/STING and IFN-I production by inflammatory macrophages as a driver of severe ANCA-associated vasculitis. Pharmacological interventions blocking this pathway ameliorate disease and accelerate recovery ...

m6A methylation potentiates cytosolic dsDNA recognition in a sequence-specific manner

Andrea Ablasser, Muhammet Fatih Gülen

Nucleic acid sensing through pattern recognition receptors is critical for immune recognition of microbial infections. Microbial DNA is frequently methylated at the N-6 position of adenines (m6A), a modification that is rare in mammalian host DNA. We show ...

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 ...

Macrophage NCOR1 Deficiency Ameliorates Myocardial Infarction and Neointimal Hyperplasia in Mice

Johan Auwerx, Hongwei Zhu, Yan Liu

Background NCOR1 (nuclear receptor corepressor 1) is an essential coregulator of gene transcription. It has been shown that NCOR1 in macrophages plays important roles in metabolic regulation. However, the function of macrophage NCOR1 in response to myocard ...

Sirt6 deletion in bone marrow-derived cells increases atherosclerosis - Central role of macrophage scavenger receptor 1

Johan Auwerx

Aims: Sirtuin 6 (Sirt6) is a NAD(+)-dependent deacetylase that plays a key role in DNA repair, inflammation and lipid regulation. Sirt6-null mice show severe metabolic defects and accelerated aging. Macrophage-foam cell formation via scavenger receptors is ...

Inhibition of mitophagy drives macrophage activation and antibacterial defense during sepsis

Johan Auwerx, Antoine Jalil

Mitochondria have emerged as key actors of innate and adaptive immunity. Mitophagy has a pivotal role in cell homeostasis, but its contribution to macrophage functions and host defense remains to be delineated. Here, we showed that lipopolysaccharide (LPS) ...

Immune serum-activated human macrophages coordinate with eosinophils to immobilize Ascaris suum larvae

Nicola Harris, Beatrice Volpe, Tiffany Babette Angélique Bouchery, Julia Esser-von Bieren, Kathleen Shah

Helminth infection represents a major health problem causing approximately 5 million disability-adjusted life years worldwide. Concerns that repeated anti-helminthic treatment may lead to drug resistance render it important that vaccines are developed but ...

Involvement of the M-CSF/IL-34/CSF-1R pathway in malignant pleural mesothelioma

Sènan Mickaël Marius Antoine D'Almeida

Background Malignant pleural mesothelioma (MPM) is a rare and aggressive cancer related to asbestos exposure. The tumor microenvironment content, particularly the presence of macrophages, was described as crucial for the development of the disease. This wo ...

Comparative RNA-Seq analyses ofDrosophilaplasmatocytes reveal gene specific signatures in response to clean injury and septic injury

Bruno Lemaitre, Jan Paul Dudzic, Elodie Julie Virginie Ramond

Drosophila melanogaster's blood cells (hemocytes) play essential roles in wound healing and are involved in clearing microbial infections. Here, we report the transcriptional changes of larval plasmatocytes after clean injury or infection with the Gram-neg ...

The Transcription Factor Nfix Requires RhoA-ROCK1 Dependent Phagocytosis to Mediate Macrophage Skewing during Skeletal Muscle Regeneration

Giuliana Rossi

Macrophages (MPs) are immune cells which are crucial for tissue repair. In skeletal muscle regeneration, pro-inflammatory cells first infiltrate to promote myogenic cell proliferation, then they switch into an anti-inflammatory phenotype to sustain myogeni ...
