CCR6 and neoplasm: The immune cell phenotype of PpardTG tumors analyzed by FlowJo-tSNE (t-distributed stochastic neighbor embedding) showed more abundant tumor-associated macrophages (TAMs), polymorphonuclear (PMN)-MDSCs/neutrophils, monocytic (M)-MDSCs, and CD4+ T cells than CD8+ T cells and B cells (Fig. 4a [left]), as well as more abundant CCR6+ immune cells than CCR6− immune cells (Fig. 4a [right]).
