Alpha1-antitrypsin improves survival in murine abdominal sepsis model by decreasing inflammation and sequestration of free heme

Background Excessive inflammation, hemolysis, and accumulation of labile heme play an essential role in the pathophysiology of multi-organ dysfunction syndrome (MODS) in sepsis. Alpha1-antitrypsin (AAT), an acute phase protein with heme binding capacity, i ...

Engineering T Cell Trafficking and Function for Enhanced Cancer Immunotherapy

Yuqing Xie

In the past decades, breakthroughs in cancer immunotherapy have led to unprecedented clinical responses in patients with advanced-stage cancers that would otherwise be fatal. However, treatment of many solid organ malignancies with highly immunosuppressive ...

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

Julien Dorier, George Coukos, Christian Iseli, Mauro Delorenzi, Alizée Jéléna Grimm, Giovanni Ciriello, Alexandre Harari, Marco Mina

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 ...

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

Freddy Radtke, Nadine Fournier, George Coukos, Marc-Olivier Sauvain, Mauro Delorenzi, 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 ...

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. ...

Ccr7 ligand delivery and co-delivery in immunotherapy

Jeffrey Alan Hubbell, Melody Swartz, Alice Anna Tomei, Iraklis Kourtis

Chemokines may be administered to a patient for immunotolerization. Chemokines include CCL19 and CCL21. Materials and methods for accomplishing tolerization and described. ...

Plasma Membrane-bound G Protein-coupled Bile Acid Receptor Attenuates Liver Ischemia/Reperfusion Injury Via the Inhibition of Toll-like Receptor 4 Signaling in Mice

Johan Auwerx, Kristina Schoonjans, Xu Wang

The plasma membrane-bound G protein-coupled bile acid receptor (TGR5) displays varied levels of expression in different tissues. TGR5-induced liver protection has been demonstrated during several liver diseases, except during ischemia/reperfusion injury (I ...

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 ...

Immune Antibodies and Helminth Products Drive CXCR2-Dependent Macrophage-Myofibroblast Crosstalk to Promote Intestinal Repair

Duncan-Bruce Sutherland, Nicola Harris, Benjamin John Marsland, Beatrice Volpe, Julia Esser-von Bieren, Jérôme Bürgi

Helminth parasites can cause considerable damage when migrating through host tissues, thus making rapid tissue repair imperative to prevent bleeding and bacterial dissemination particularly during enteric infection. However, how protective type 2 responses ...

Regulation of TGF beta and related signals by precursor processing

Daniel Constam

Secreted cytokines of the TGF beta family are found in all multicellular organisms and implicated in regulating fundamental cell behaviors such as proliferation, differentiation, migration and survival. Signal transduction involves complexes of specific ty ...

TGR5 reduces macrophage migration through mTOR-induced C/EBP beta differential translation

Kristina Schoonjans, Alessia Perino, Matthias Alexander Sokrates Stein, Mitsunori Nomura, Thijs Pols

The bile acid-responsive G protein-coupled receptor TGR5 is involved in several metabolic processes, and recent studies suggest that TGR5 activation may promote pathways that are protective against diet-induced diabetes. Here, we investigated the role of m ...

Dendritic cell chemotaxis in 3D under defined chemokine gradients reveals differential response to ligands CCL21 and CCL19

Melody Swartz, Marco Pisano, Ulrike Haessler, Mingming Wu

Dendritic cell (DC) homing to the lymphatics and positioning within the lymph node is important for adaptive immunity, and is regulated by gradients of CCL19 and CCL21, ligands for CCR7. Despite the importance of DC chemotaxis, it is not well understood ho ...

FcRgamma activation regulates inflammation-associated squamous carcinogenesis

Michele De Palma, Ferdinando Pucci

Chronically activated leukocytes recruited to premalignant tissues functionally contribute to cancer development; however, mechanisms underlying pro- versus anti-tumor programming of neoplastic tissues by immune cells remain obscure. Using the K14-HPV16 mo ...

Dendritic cell chemotaxis in 3D : new tools and insights

Ulrike Haessler

Dendritic cells (DCs) are crucial for the onset of adaptive immunity. Their outstanding migratory capacities in combination with their antigen presenting properties make them perfectly suited to pick up antigens in the periphery and transport them to the l ...

Fluid flow regulates stromal cell organization and CCL21 expression in a tissue-engineered lymph node microenvironment

Melody Swartz, Alice Anna Tomei

In the paracortex of the lymph node (LN), T zone fibroblastic reticular cells (TRCs) orchestrate an immune response by guiding lymphocyte migration both physically, by creating three-dimensional (3D) cell networks, and chemically, by secreting the chemokin ...
