Therefore, we studied M1/M2 infiltrated monocytes and N1/N2 infiltrated neutrophils populations 1 day after stroke, demonstrating that aged animals not only had a higher number of infiltrated M1 monocytes (Cd11b+, CD45hi, CCR2+, Ym1− cells, Figure 3B and plot) but also of N1 neutrophils (Cd11b+, Ly6Ghi, CD45hi, Ym1− cells, Figure 3A and plot) than young animals (P < 0.05 young vs. aged; Figure 3A, B). Here, ITGAM is linked to Stroke.
