CDH1 and skin neoplasm: Although we do not provide direct evidence of the mechanism by which TGF-β1 inhibits DC migration toward TDLNs in this study, Weber et al. reported that TGFβ1 inhibits DC migration from skin tumors to draining lymph nodes, based on the disappearance of E-cadherin+ DCs from draining lymph nodes consistent with our results [20].
