PURPOSE To establish a novel, targeted lentivirus-mediated LEP503-HSV-tk/GCV suicide gene therapy system combined with all trans-retinoic acid (ATRA) for the inhibition of human lens epithelial cell (HLEC) proliferation and treatment of posterior capsular opacification (PCO) after cataract surgery; to estimate the enhancement of the bystander effect by(More)
PURPOSE Retinal microglia can be activated and recruited by chemokines and play a protective role in early retinal degeneration. CC-chemokine ligand 2 (CCL2) and its receptor, CC-chemokine receptor 2 (CCR2), have been implicated as key mediators for the trafficking and accumulation of microglial cells in lesioned tissue. The current study investigates(More)
Retinal microglia play an important role as resident immunocompetent and phagocytic cells in the event of injury and disease. Retinal microglia and microglia precursor transplantation show a rescue effect in ischemic retina and retinal degeneration. However, studies of retinal microglia have been hampered by the difficulty of obtaining sufficient numbers of(More)
Recent progress in regenerative medicine has suggested that mesenchymal stem cell (MSC)-based therapy is a novel potential cure for diabetes. Betatrophin is a newly identified hormone that can increase the production and expansion of insulin-secreting β-cells when administered to mice. In this study, we evaluated the effect of betatrophin overexpression by(More)
