CD8A and ischemic stroke: Based on CIBERSORT, as shown in Figure 6, the fractions of CD8+ T cells, gamma delta T cells, resting dendritic cells, and follicular helper T cells were consistently lower in the normal tissue than in ischemic stroke samples, whereas the fraction of activated NK cells, M0 macrophages, activated mast cells, and neutrophils were significantly lower in the ischemic stroke samples.
