Characterization of Cyclo His-Pro for the prevention and treatment of liver disease and muscular dystrophy

Alessia De Masi

The natural compound Cyclo Histidine-Proline (CHP) was initially discovered in the brain, but thereafter evaluated in the context of diabetes because of its hypoglycemic action. The pharmacokinetics and the toxicological profile of CHP showed it can be dos ...

Dissecting the role of the mitochondrial carrier SLC25A47

Nadia Bresciani

Transporters of the SLC25 mitochondrial carrier superfamily bridge cytoplasmic and mitochondrial metabolism by channeling metabolites across mitochondrial membranes and are pivotal for metabolic homeostasis. Despite their physiological relevance as gatekee ...

Defined matrices for epithelial organoid culture and disease modelling

Saba Rezakhani

Advances in our understanding of the biology of stem cells and their niches have provided the necessary foundation to create in vitro complex self-organizing three-dimensional (3D) structures called organoids. While organoids represent a highly promising n ...

Apelin-13 Protects Corpus Cavernosum Against Fibrosis Induced by High-Fat Diet in an MMP-Dependent Mechanism

Nikolaos Stergiopoulos, Rafaela Fernandes Da Silva, Mikaël Nils Sturny, Augusto Martins Lima, Maiia Bragina

Background: An increased fibrosis of the corpora cavernosa is a prevalent process that underlies most cases of erectile dysfunction. Apelin, an endogenous circulating peptide, has been documented as an important effector on cardiovascular homeostasis, cont ...

Neonatal Manifestations of Chronic Granulomatous Disease: MAS/HLH and Necrotizing Pneumonia as Unusual Phenotypes and Review of the Literature

Alessandro Borghesi

Chronic granulomatous disease (CGD) is a rare inborn error of immunity (IEI), characterized by a deficient phagocyte killing due to the inability of NADPH oxidase to produce reactive oxygen species in the phagosome. Patients with CGD suffer from severe and ...

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- ...

Microencapsulated human mesenchymal stem cells decrease liver fibrosis in mice

Jutta Christine Wandrey, Redouan Mahou

Background & Aims: Mesenchymal stem cell (MSC) transplantation was shown to be effective for the treatment of liver fibrosis, but the mechanisms of action are not yet fully understood. We transplanted encapsulated human MSCs in two mouse models of liver fi ...

The Mechanical Environment Modulates Intracellular Calcium Oscillation Activities of Myofibroblasts

Boris Hinz, Adriano Garonna, Lysianne Follonier Castella

Myofibroblast contraction is fundamental in the excessive tissue remodeling that is characteristic of fibrotic tissue contractures. Tissue remodeling during development of fibrosis leads to gradually increasing stiffness of the extracellular matrix. We pro ...

Embryonic Stem Cell-Based Cardiopatches Improve Cardiac Function in Infarcted Rats

Jeffrey Alan Hubbell

Pluripotent stem cell-seeded cardiopatches hold promise for in situ regeneration of infarcted hearts. Here, we describe a novel cardiopatch based on bone morphogenetic protein 2-primed cardiac-committed mouse embryonic stem cells, embedded into biodegradab ...

A New Lock-step Mechanism of Matrix Remodelling Based on Subcellular Contractile Events

Boris Hinz, Jean-Jacques Meister, Lara Buscemi Estefanell, Lysianne Follonier Castella

Myofibroblasts promote tissue contractures during fibrotic diseases. To understand how spontaneous changes in the intracellular calcium concentration, Ca2+, contribute to myofibroblast contraction, we analysed both Ca2+ and subcellular contractio ...

Wound repair and regeneration

Yann Barrandon

The repair of wounds is one of the most complex biological processes that occur during human life. After an injury, multiple biological pathways immediately become activated and are synchronized to respond. In human adults, the wound repair process commonl ...

Liver-specific inactivation of Notch2, but not Notch1, compromises intrahepatic bile duct development in mice

Freddy Radtke

The Notch pathway is an evolutionary conserved, intercellular signaling pathway that plays an important role in cell fate specification and the embryonic development of many organs, including the liver. In humans, mutations in the Notch receptor ligand Jag ...

Myofibroblast contraction activates latent TGF-beta1 from the extracellular matrix

Boris Hinz, Jean-Jacques Meister

The conjunctive presence of mechanical stress and active transforming growth factor beta1 (TGF-beta1) is essential to convert fibroblasts into contractile myofibroblasts, which cause tissue contractures in fibrotic diseases. Using cultured myofibroblasts a ...
