Fig. 6. In vivo effects of different hypomethylation levels on GvHD scores.

Fig. 6

Male and female 8- to 11-week old NSG HLA-A*02 mice were injected intravenously with different batches of TX200 Tregs that were isolated with 2 different gating strategies (TR101 and TR100) and characterized by different levels of FOXP3 hypomethylation. Mice were observed for up to 27 days or until ethical endpoints were reached (represented by a cross). Evolution of GvHD scores is shown based on scoring in 5 categories (0: no findings, 1: mild, 2: moderate, 3: severe) combined into a total score. Data are presented as mean ± SEM with n = 5 for 80.8% hypomethylation, n = 3 for 92% and 89.1%, n = 20 for 69%, n = 2 for 98%, and n = 5 for 100%. Average percentage of transduction was 59.5 ± 2.7% (mean ± SEM) and cells were on average 95.3 ± 2.8% CD4+/CD45RA+/CD25+/FoxP3+ (mean ± SEM).
