Though Foxp3+ Treg expansion has been observed in the mLN of S. ratti-infected mice [22], we did not observe increased frequencies of polyclonal Foxp3+ and Foxp3+GATA3+ CD4+ T cells in the lungs of mice 14 days post S. ratti-infection relative to naïve mice (Fig 1B and 1C). This evidence concerns the gene GATA3 and infection.
