In addition, correlation analysis showed that the expression level of CX3CR1 was positive association with infiltrating levels of B cells (R = 0.31, P = 3.10e−12), CD8+ T cells (R = 0.26, P = 7.93e−09), CD4+ T cells (R = 0.11, P = 1.41e−02), macrophages (R = 0.32, P = 4.29e−13), dendritic cells (R = 0.27, P = 2.98e−09), and neutrophil (R = 0.25, P = 3.25e−08) in epithelial ovarian cancer. This evidence concerns the gene CX3CR1 and ovarian carcinoma.
