Morphine Enhances The Permeability Across Vascular Endothelial Cell Barriers, Jenine Anday
Seton Hall University Dissertations and Theses (ETDs)
Using three types of in vitro endothelial cell barrier models, we investigated the direct effects and mechanisms of morphine on vascular permeability. Our current studies illustrate LPS induces permeability across these VEC barriers, and is significantly enhanced when co-treated with morphine, displayed using the [ 14 CJ-inulin paracellular marker. Incubation with morphine alone induces permeability in a concentration depeodent manner, and is not blocked by the addition of naloxone. Morphine enhances the detrimental effects of LPS on cell viability and alone also decreases endothelial cell viability, concentration-dependently, which is also not affected by naloxone, as demonstrated by the trypan blue …
