Soft Hydrogel Zwitterionic Coatings Minimize Fibroblast and Macrophage Adhesion on Polyimide Substrates

Silvestro Micera

Minimizing the foreign body reaction to polyimide-based implanted devices plays a pivotal role in several biomedical applications. In this work, we propose materials exhibiting nonbiofouling properties and a Young's modulus reflecting that of soft human ti ...

House dust mite drives proinflammatory eicosanoid reprogramming and macrophage effector functions

Nicola Harris, Tiffany Babette Angélique Bouchery, Julia Esser-von Bieren

Background Eicosanoid lipid mediators play key roles in type 2 immune responses, for example in allergy and asthma. Macrophages represent major producers of eicosanoids and they are key effector cells of type 2 immunity. We aimed to comprehensively track e ...

Cancer cell-derived long pentraxin 3 (PTX3) promotes melanoma migration through a toll-like receptor 4 (TLR4)/NF-kappa B signaling pathway

Mélanie Louise Tichet

Cutaneous melanoma is one of the most aggressive cancers characterized by a high plasticity, a propensity for metastasis, and drug resistance. Melanomas are composed of phenotypically diverse subpopulations of tumor cells with heterogeneous molecular profi ...

Integrin-Mediated Macrophage Adhesion Promotes Lymphovascular Dissemination in Breast Cancer

Michele De Palma, Mario Leonardo Squadrito, Sina Nassiri

Lymphatic vasculature is crucial for metastasis in triple-negative breast cancer (TNBC); however, cellular and molecular drivers controlling lymphovascular metastasis are poorly understood. We define a macrophage-dependent signaling cascade that facilitate ...

Rapid activation of tumor-associated macrophages boosts preexisting tumor immunity

Michele De Palma

Depletion of immunosuppressive tumor-associated macrophages (TAMs) or reprogramming toward a proinflammatory activation state represent different strategies to therapeutically target this abundant myeloid population. In this study, we report that inhibitio ...

Absence of specific alternatively spliced exon of CD44 in macrophages prevents colitis

Ulrich Hoffmann, Riccardo Sabatini

CD44 is a transmembrane molecule appearing in numerous isoforms generated by insertions of alternatively spliced variant exons (CD44v) and having various binding partners. CD44v7 on T cells was proposed to promote colitis by preventing T-cell apoptosis. He ...

T cell–induced CSF1 promotes melanoma resistance to PD1 blockade

Michele De Palma, George Coukos, Krisztian Homicsko, Sina Nassiri

Colony-stimulating factor 1 (CSF1) is a key regulator of monocyte/macrophage differentiation that sustains the protumorigenic functions of tumor-associated macrophages (TAMs). We show that CSF1 is expressed in human melanoma, and patients with metastatic m ...

Periostin Limits Tumor Response to VEGFA Inhibition

Michele De Palma, Ece Kadioglu, Ioanna Keklikoglou

Resistance to antiangiogenic drugs limits their applicability in cancer therapy. Here, we show that revascularization and progression of pancreatic neuroendocrine tumors (PNETs) under extended vascular-endothelial growth factor A (VEGFA) blockade are depen ...

Perivascular macrophages in health and disease

Michele De Palma

Macrophages are a heterogeneous group of cells that are capable of carrying out distinct functions in different tissues, as well as in different locations within a given tissue. Some of these tissue macrophages lie on, or close to, the outer (abluminal) su ...

Unpaired extracellular cysteine mutations of CSF3R mediate gain or loss of function

Oliver Hantschel, Tim Kükenshöner

Exclusive of membrane-proximal mutations seen commonly in chronic neutrophilic leukemia (e.g. T618I), functionally defective mutations in the extracellular domain of the granulocyte colony-stimulating factor receptor (CSF3R) have been reported only in seve ...

Role of myeloid cells in mediating protection against parasitic helminth larvae

Beatrice Volpe

Helminth infections affect around one fourth of the world population living in the poorest regions of our planet. Helminths mainly cause debilitating chronic effects on health, development and nutritional status of infected people. The development of a vac ...

Automated microfluidic sorting of mammalian cells labeled with magnetic microparticles for those that efficiently express and secrete a protein of interest

Amar Rida, Nicolas Mermod

We developed a method for the fast sorting and selection of mammalian cells expressing and secreting a protein at high levels. This procedure relies on cell capture using an automated microfluidic device handling antibody-coupled magnetic microparticles an ...
