At 3 days after stroke the difference is not statistically significant, but a tendency towards a reduced cell number (1.21-fold reduction) can be observed in TLR2−/− mice compared with WT group (control: WT: 5.71 ± 1.15%, n = 4; TLR2−/−, 6.23 ± 1.47%, n = 4, P = 0.793; 3 days: WT, 20.44 ± 0.55%; TLR2−/−, 16.91 ± 2.26%, n = 4, P = 0.137; 7 days: WT, 32.44 ± 1.69%; TLR2−/−, 23.55 ± 2.52%, n = 4, P = 0.026). Here, TLR2 is linked to Stroke.
