We analyzed the correlations between SNAI1 expression and immune marker genes of different immune cells, included CD8+ T cell, T cell (general), B cell, monocyte, tumor-associated macrophage (TAM), M1 macrophage, M2 macrophage, neutrophils, natural killer cell, dendritic cell, T helper cell (Th) 1, Th2, follicular helper T cell (Tfh), Th17, regulatory T cell (Treg), and T cell exhaustion. This evidence concerns the gene SNAI1 and neoplasm.
