Macrophage plasticity is the ability of mononuclear phagocytes to change phenotype, function, and genetic reprogramming upon encounter of specific local stimuli. In the tumor microenvironment, Tumor‐Associated Macrophages (TAMs) acquire an immune‐suppressive and tumor‐promoting phenotype. With the aim to re‐educate TAMs to antitumor effectors, in this study, we used two immunestimulatory compounds:...
It is disputed whether inflammasome activation leading to secretion of pro-inflammatory interleukin (IL)-1β in macrophages transpires independently of cell death or whether the two processes are linked. Here, we synthesized hollow carbon spheres (HCS) and investigated their effects on primary human monocyte-derived macrophages (HMDM); short (500 nm) non-functionalized single-walled carbon nanotubes...
Carbon nanotubes (CNTs) may elicit inflammatory responses following pulmonary exposure. Conversely, enzymatic biodegradation of CNTs by inflammatory cells has also been reported. The aim of this study was to study the degradation of oxidized single-walled CNTs (ox-SWCNTs) by lactoperoxidase (LPO), a secreted peroxidase present in the airways, and whether pulmonary surfactant affects this biodegradation...
