In vivo depletion of Treg cells with anti-CD25 antibodies was performed as previously described [9 (link)]. We verified that this schedule was very effective in the depletion of Treg cells without causing significant alterations in other T cell subsets. Briefly, C57BL/6 Foxp3GFP mice were given i.p. injections of 500 μg of anti-CD25 (clone PC61) or control rat IgG (BioXcell, USA) diluted in sterile PBS. Antibodies were administered on days -3 and +3 relative to infection with P. brasiliensis yeasts.
