TLR4 and melanoma: The role of TLR4 is evaluated that TLR4 can induce dendritic cells,activate environmental danger molecules, and inhibit melanoma.14,15 It has beenproven that melanoma is regulated by interfering TLR4 signals.16 In addition, some studies show that EGCG can inhibit TLR4 expression orinhibit the TLR4 signaling pathway.17,18 This study then aimed todiscover the possible relationship between TP and TLR4 in melanoma treatment.
