Pre-treatment with rIL-17B significantly decreased paclitaxel-induced cytotoxicity in BT20 and MDA-MB-468 cells (derived from TN/basal-like breast cancers) and also in MCF7 cells (from a luminal A breast cancer) (Figure 3B), while it had not effect on the IL-17RB negative MDA-MB-435S cell line (Supplementary Figure 3A and 3B). Here, IL17RB is linked to breast carcinoma.
