TNFRSF18 and infection: To strengthen our reasoning even further, we blocked the activity of Tregs by co-administering neutralizing antibodies against CD25 and GITR (i.v.)at day 4 and day 6 post Bm-L3 infection (Figure 4D) and quite notably found significantly depleted percentages of Tregs (Figure 4E), along with drastically reduced Bm-L3 burden in treated animals (Figure 4F).
