Although no statistical difference for expression of IL-4, IL-17 and Foxp3 mRNA levels in carcinoma tissues of non-IBC and IBC patients was observed, there was a trend for upregulation of IL-4 and downregulation of Foxp3 mRNA levels in carcinoma tissues of IBC in comparison to non-IBC (S3 Fig). Here, IL4 is linked to carcinoma.
