Yet the associated mechanisms and especially the role of post-stroke neuroinflammation are still poorly understood. Our aim was to elucidate the highly debated (harmful or beneficial) role of microglia in the context of an ischemic insult. Our unique experimental design includes the exogenous application of fluorescently labeled microglial cell line BV2 to transgenic (fluorescently labeled neurons) organotypic hippocampal cultures. We could thus modify microglia prior to application, reach pathophysiologically relevant microglia numbers, and ensure that the observed effects were mediated exclusively by the microglia. <h3>PRINCIPAL FINDINGS</h3> <h3>1.
