Abstract Proteolytic release of transmembrane proteins from the cell surface, so called ectodomain shedding, is a key process in inflammation. Inactive rhomboid 2 (iRhom2) plays crucial role this context, that it guides maturation and function sheddase ADAM17 (a disintegrin metalloproteinase 17) immune cells, and, ultimately, its ability to inflammatory mediators such as tumor necrosis factor α (TNFα). Yet, macrophage sheddome iRhom2/ADAM17, which collection substrates are released by...
Despite low levels of vascular endothelial growth factor (VEGF)-A, the secretome human Wharton’s jelly (WJ) mesenchymal stromal cells (MSCs) effectively promoted proangiogenic responses in vitro, which were impaired upon depletion small (~140 nm) extracellular vesicles (EVs). The isolated EVs shared VEGF-A profile and expressed five microRNAs, upregulated compared to fetal dermal MSC-derived EVs. These microRNAs exclusively targeted gene within 54 Gene Ontology (GO) biological processes, 18...
Ischemia/reperfusion injury (IRI) represents one of the leading causes primary non-function acute liver transplantation failure. IRI, generated by an interruption organ blood flow and subsequent restoration upon transplant, i.e., reperfusion, generates activation inflammatory cascade from resident Kupffer cells, first to neutrophils recruitment second apoptosis parenchyma. Recently, human mesenchymal stromal/stem cells (hMSCs) derivatives have been implemented for reducing damage induced...
Abstract Cigarette smoking impairs the lung innate immune response making smokers more susceptible to infections and severe symptoms. Dysregulation of cell death is emerging as a key player in chronic inflammatory conditions.
