CD8A and ischemic stroke: To determine the number of immune cells in ischemic stroke samples, the CIBERSORT method was used, and we found that the fractions of resting dendritic cells, follicular helper T cells, CD8+ T cells, and gamma delta T cells were significantly higher in the ischemic stroke samples than in normal tissue, whereas the fraction of neutrophils, activated M0 macrophages, activated mast cells, and NK cells was significantly lower.
