However, the proportions of CD4+ memory resting T cells (P < 0.001), gamma delta T cells (P = 0.031), M1 Macrophages (P = 0.020), M2 Macrophages (P < 0.001), and neutrophils (P = 0.002) in endometriosis tissues were significantly higher than those in normal tissues (Fig. 5B). This evidence concerns the gene CD4 and endometriosis.
