In addition, FKBP1A expression has a negative correlation with tumor purity (r = −0.318, p = 1.03 × 10–2) and significant positive correlations with infiltrating levels of B cells (r = 0.351, p = 2.20 × 10−11), CD8+ cells (r = 0.466, p = 8.11 × 10−20), CD4+ T cells (r = 0.279, p = 1.49 × 10−7), macrophages (r = 0.482, p = 3.24 × 10−21), neutrophils (r = 0.386, p = 1.05 × 10−13), and dendritic cells (r = 0.525, p = 1.84 × 10−25) (Figure 8A). The gene discussed is CD4; the disease is neoplasm.
