The peripheral immune system plays a role in delayed neural injury after stroke. This response originates from the spleen as splenectomy prior to middle cerebral artery occlusion (MCAO) in rats significantly reduces infarct volume in the brain. This research is based on the hypothesis that inhibiting the splenic response will reduce neurodegeneration after stroke. Studies in animals have implicated lymphocytes as the immune cell type that is detrimental following MCAO. Interferon gamma (IFNγ) has been identified as a pro-inflammatory cytokine that is also detrimental following stroke. IFNγ is important because it activates microglia and macrophages in a pro-inflammatory nature that …
