Ceramide subspecies are differentially regulated in the peri-infarct cortex. (a) Total ceramide, ceramide 16:0, 18:0, and 24:0 in the time course after photothrombotic stroke compared to sham. Asterisks for p values as well as ceramide 18:1 and 24:1 are not shown (see Section 3). (b) Ratios for ceramide 16:0/ceramide 24:0 + 24:1. Data are presented as means ± SD. Differences between sham and PT group were analyzed using Student's unpaired two-tailed t-test.^∗∗ p ≤ 0.01; ^∗∗∗ p ≤ 0.001; n.s., nonsignificant; n = 8–10.
