Recent advances in fluorescence microscopy allow three-dimensional analysis of HIV-1 preintegration complexes in the nuclei of infected cells. To extend this investigation to gammaretroviruses, we engineered a fluorescent Moloney murine leukemia virus (MLV) system consisting of MLV-integrase fused to enhanced green fluorescent protein (MLV-IN-EGFP). A comparative analysis of lentiviral (HIV-1) and gammaretroviral (MLV) fluorescent complexes in the nuclei of infected cells revealed their different spatial distributions. This research tool has the potential to achieve new insight into the nuclear biology of these retroviruses.

Abstract
Recent advances in fluorescence microscopy allow three-dimensional analysis of HIV-1 preintegration complexes in the nuclei of infected cells. To extend this investigation to gammaretroviruses, we engineered a fluorescent Moloney murine leukemia virus (MLV) system consisting of MLV-integrase fused to enhanced green fluorescent protein (MLV-IN-EGFP). A comparative analysis of lentiviral (HIV-1) and gammaretroviral (MLV) fluorescent complexes in the nuclei of infected cells revealed their different spatial distributions. This research tool has the potential to achieve new insight into the nuclear biology of these retroviruses.File in questo prodotto:
