DLX6 and neoplasm: Specifically, the high expression of DLX6 suppresses the infiltration of B cells, cytotoxic cells, T cells, neutrophils, central memory T cells, effector memory T cells, γδT cells, and dendritic cells, all of which play key roles in tumor immune responses, including antitumor cytotoxicity, immune memory formation, and the initiation of specific immune responses.
