BACKGROUND Gadopentate dimeglumine (Gd-DTPA) enhanced magnetic resonance imaging (MRI) is widely applied for the visualization of blood brain barrier (BBB) breakdown in multiple sclerosis and its animal model, experimental autoimmune encephalomyelitis (EAE). Recently, the potential of magnetic nanoparticles to detect macrophage infiltration by MRI was(More)
The Virchow-Robin spaces (VRS), perivascular compartments surrounding small blood vessels as they penetrate the brain parenchyma, are increasingly recognized for their role in leucocyte trafficking as well as for their potential to modulate immune responses. In the present study, we investigated VRS numbers and volumes in different brain regions in 45(More)
The role of phagocytosing immune cells in Alzheimer's pathology can be studied experimentally in APP23 transgenic mice. This present study intended to label phagocytosing immune cells in the plaque periphery of APP23 mice in vivo by intraventricular injection of VSOP-C184, a phagocytosable iron oxide nanoparticle MRI contrast agent. Firstly, the dosages of(More)
