Cecropins contribute to Drosophila host defense against a subset of fungal and Gram-negative bacterial infection

Bruno Lemaitre, Mark Austin Hanson, Alexia Laurie Carboni

Cecropins are small helical secreted peptides with antimicrobial activity that are widely distributed among insects. Genes encoding Cecropins are strongly induced upon infection, pointing to their role in host defense. In Drosophila, four cecropin genes cl ...

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- ...

The Intestinal Microbiota Contributes to the Ability of Helminths to Modulate Allergic Inflammation

Jacques Rougemont, Laure Menin, Nicola Harris, Mario Michael Zaiss, Ilaria Mosconi, Alessandra Piersigilli, Benjamin John Marsland, Lalit Kumar Dubey, Alexis Rapin, Luc Xavier Marie Lebon

Intestinal helminths are potent regulators of their host's immune system and can ameliorate inflammatory diseases such as allergic asthma. In the present study we have assessed whether this anti-inflammatory activity was purely intrinsic to helminths, or w ...

Biomechanical forces promote blood development through prostaglandin E2 and the cAMP-PKA signaling axis

Olaia Maria Naveiras Torres-Quiroga, Nan Li

Blood flow promotes emergence of definitive hematopoietic stem cells (HSCs) in the developing embryo, yet the signals generated by hemodynamic forces that influence hematopoietic potential remain poorly defined. Here we show that fluid shear stress endows ...

Propagation of fast and slow intercellular Ca2+ waves in primary cultured arterial smooth muscle cells

Jean-Jacques Meister, Jean-Louis Bény, Nadia Halidi

Smooth muscle contraction is regulated by changes in cytosolic Ca2+ concentration (Ca2+). In response to stimulation, Ca2+ increase in a single cell can propagate to neighbouring cells through gap junctions, as intercellular Ca2+ waves. To investigate ...

Calcium Dynamics and Intercellular Communication in Arterial Smooth Muscle Cells in Vitro

Nadia Halidi

Tissue blood flow is controlled by changes in the diameter of the arteries and arterioles through coordinated contraction and relaxation of smooth muscle cells (SMCs) within the vascular wall. The contraction of SMCs is primarily regulated by the intracell ...
