CD8A and endometriosis: For the MCP-counter method, we found that T cells (P = 1.6e-6), CD8+ T cells (P = 0.00018), cytotoxic lymphocytes (P = 0.0038), and NK cells (P = 0.00016) were elevated in the eutopic endometria of patients with endometriosis compared to the endometria of healthy controls (Figures 3A, B), while monocytic lineage was decreased in the eutopic endometrium samples (P = 0.04699).
