BATF3 and melanoma: For example, oncogenic Wnt/β-catenin signaling in melanoma decreased T cell infiltration by downregulating the expression of CCL4, which recruits the basic leucine zipper TF ATF-like 3 (BATF3)-lineage dendritic cells (DCs) that cross-present tumor-derived antigens through major histocompatibility complex class I19.
