As shown in Figure S2, the mRNA expression levels of NEURL1B, CNTN1, and FCER2 were positively correlated with a variety of immune cells in the tumor microenvironment (CD4+ T cell: R/p = 0.251/2.28 × 10−6, 0.193/3.17 × 10−4, and 0.177/9.45 × 10−4, respectively; CD8+ T cell: R/p = 0.21/8.39 × 10−5, 0.142/8.36 × 10−3, and 0.14/9.18 × 10−3, respectively; Tregs cell: R/p = 0.292/3.23 × 10−8, 0.257/1.28 × 10−6, and 0.146/ 6.46 × 10−3, respectively; B cell: R/p = 0.183/6.34 × 10−4, 0.173/1.29 × 10−3, and 0.382/2.05 × 10−13, respectively). The gene discussed is CNTN1; the disease is neoplasm.
