Quantitative relationships between SMAD dynamics and target gene activation kinetics in single live cells

Felix Naef, David Michael Suter, Torgil Elias Friman, Onur Tidin

The transduction of extracellular signals through signaling pathways that culminate in a transcriptional response is central to many biological processes. However, quantitative relationships between activities of signaling pathway components and transcript ...

Mesenchymal stromal cell exosomes prevent and revert experimental pulmonary fibrosis through modulation of monocyte phenotypes

Sina Nassiri, Nahal Mansouri

Mesenchymal stromal/stem cell (MSC) therapy has shown promise in experimental models of idiopathic pulmonary fibrosis (IPF). The aim of this study was to test the therapeutic effects of extracellular vesicles produced by human BM MSCs (MEx) in a bleomycin- ...

HIV-1 Vpu is a potent transcriptional suppressor of NF-κB-elicited antiviral immune responses

Jacques Fellay, Christian Hammer

Many viral pathogens target innate sensing cascades and/or cellular transcription factors to suppress antiviral immune responses. Here, we show that the accessory viral protein U (Vpu) of HIV-1 exerts broad immunosuppressive effects by inhibiting activatio ...

Molecular Profiling and Functional Analysis of Macrophage-Derived Tumor Extracellular Vesicles

Michele De Palma, Romain Hamelin, Chiara Cianciaruso, Sina Nassiri, Bruno Torchia, Tim Beltraminelli, Florent Philippe Maurice Duval

Extracellular vesicles (EVs), including exosomes, modulate multiple aspects of cancer biology. Tumor-associated macrophages (TAMs) secrete EVs, but their molecular features and functions are poorly characterized. Here, we report methodology for the enrichm ...

Targeting small molecule drugs to T cells with antibody-directed cell-penetrating gold nanoparticles

Francesco Stellacci, Ahmet Bekdemir

We sought to develop a nanoparticle vehicle that could efficiently deliver small molecule drugs to target lymphocyte populations. The synthesized amphiphilic organic ligand-protected gold nanoparticles (amph-NPs) were capable of sequestering large payloads ...

Role of metabolism and mitochondria during glucose sensing and glucose-induced dysfunction in human pancreatic beta-cells

Isabelle Chareyron

Glucose sensing and regulation of insulin secretion are the two main functions performed by the pancreatic beta-cell. Together these processes contribute to the tight control of blood glucose in our body. Compromising the ability of the beta-cells to prope ...

Elucidating regulatory mechanisms shaping the transcriptome and proteome of the gut immune response in Drosophila melanogaster

Michael Vincent Frochaux

Work on Drosophila melanogaster paved the way to our current understanding of modern genetics. Since then, this model organism has contributed greatly to various fields such as neurobiology, development, and immunology. The discovery and analysis of the va ...

Mutation update: TGFBI pathogenic and likely pathogenic variants in corneal dystrophies

Daniel Francis Schorderet

Human transforming growth factor beta-induced (TGFBI), is a gene responsible for various corneal dystrophies. TGFBI produces a protein called TGFBI, which is involved in cell adhesion and serves as a recognition sequence for integrins. An alteration in cel ...

Quantitative single cell dynamics of signaling and transcriptional response in mammalian cells

Onur Tidin

Cells live in ever-changing environments, thereby facing a variety of dynamic environmental signals. Environmental stimuli elicit intracellular responses through signaling pathways, which converge on transcriptional activation or repression of target genes ...

Novel tools to dissect stem cell metabolism at single cell level

Gennady Nikitin

Hematopoietic stem cells (HSC) are responsible for the life-long maintenance of our blood system. Their long-term capacity to both self-renew and differentiate and the ability to efficiently â homeâ to their bone marrow niches when injected in the blood ...

Structural and functional analysis of host attachment proteins from contractile injection systems

Michel Plattner

Bacteriophages of the myoviridae family, R-type pyocin, Photorhabus virulence cassette (PVC), Serratia antifeeding prophage (Afp) and type 6 secretion system (T6SS) form a class of contractile injection systems that share common structural and functional c ...
