Using Multiphoton Intravital Microscopy to Study Neutrophil Transmigration and Blood−Brain Barrier Permeability in a Mouse Model of Herpes Simplex Virus Encephalitis
摘要
Multiphoton intravital microscopy (MP-IVM) is an imaging technique used for the observation of living organisms at a microscopic resolution. The tissue of interest is exposed through a window allowing imaging of cells in real time. Using MP-IVM, the temporospatial kinetics of leukocyte transendothelial migration can be visualized and quantitated using reporter mice and cell-specific fluorophore-conjugated monoclonal antibodies to track the leukocytes within and outside of vascular beds. Here we describe a method used to study neutrophil transendothelial migration and blood−brain barrier permeability in a mouse model of herpes simplex virus I (HSV) encephalitis.
