After demonstrating the relationship between SIgA levels and eosinophils controlling larval migration, and after verifying the increase in the expression of TLR2 and TLR4 in single-infected mice (S3 Fig), we assessed the potential role of TLRs in triggering SIgA production and eosinophilia. This evidence concerns the gene TLR4 and Increased total eosinophil count.
