Inflammation plays an important role in the pathogenesis of ischemic stroke
including an acute and prolonged inflammatory process. The role of neutrophil
granulocytes as first driver of the immune reaction from the blood site is under
debate due to controversial findings. In bone marrow chimeric mice we were able
to study the dynamics of tdTomato-expressing neutrophils and GFP-expressing
microglia after photothrombosis using intravital two-photon microscopy. We
demonstrate the infiltration of neutrophils into the brain parenchyma and confirm
a long-lasting contact between neutrophils and microglia as well as an uptake of
neutrophils by microglia clearing the brain from peripheral immune cells.
