Abstract The prolonged exposure of macrophages to endotoxin occurs in various chronic inflammatory conditions, including long-term inflammation triggered by particle-releasing implanted biomaterials, progressive pulmonary obstructive conditions, chronic bronchitis, colitis and hepatitis characterized by sustained exposure to gut-derived lipopolysaccharide (LPS).

Abstract During the foreign body response, immune cells are metabolically rewired after exposure to breakdown products of various biomaterials, including polylactide (PLA) and polyethylene. Particles of polyethylene interact with Toll-like receptor 4 on macrophages, resulting in increased oxygen consumption that forms reactive oxygen species at complex I of the mitochondrial electron transport chain (mETC).

Abstract The incidence of breast cancer remains high worldwide and is associated with a significant risk of metastasis to the brain that can be fatal; this is due, in part, to the inability of therapeutics to cross the blood brain barrier (BBB). Extracellular vesicles (EVs) have been found to cross the BBB and further, have been used to deliver drugs to tumors.
