*2.1. Concentrations of Cytokines and Chemokines in PF*

Concentrations of IL-2, IFN-γ, IL-17A, TNF, IL-4, IL-10 and IL-6 in the peritoneal fluid of control women and patients with endometriosis are shown in Table 1. Women with

endometriosis had increased concentrations of IL-6 and IL-10. There were no differences between the control and endometriosis groups in concentrations of IL-2, IFN-γ, IL-17A, TNF, and IL-4.

**Table 1.** Immunoregulatory cytokine concentrations in peritoneal fluid from patients with endometriosis and control women.


Values are expressed in pg/mL and are shown as medians (range). \* *p*-values were calculated by Mann–Whitney U test. ns, non-significant.

Concentrations of CCL2, CCL5, CXCL8 and CXCL9 in PF of control women and patients with endometriosis are shown in Table 2. PF from the women with endometriosis displayed significantly increased concentrations of CCL2, CXCL8 and CXCL9 as compared with the control subjects.

**Table 2.** Chemokine concentrations in peritoneal fluid from patients with endometriosis and control women.


Values are expressed in pg/mL and are shown as medians and a range. \* *p*-values were calculated by Mann– Whitney U test. ns, non-significant.
