Cytotoxic activity of peripheral blood mononuclear cells in patients with endometriosis: A cross-sectional study.

Background: Endometriosis is believed to be associated with dysfunction of the lymphocyte population and cytotoxicity of natural killer (NK) cells, induced by the production of interleukin-2 (IL-2).

Objective: This study aimed to investigate T lymphocytes and NK cell activity in the peripheral blood mononuclear cells (PBMCs) of women with endometriosis.

Materials And Methods: PBMCs were obtained from the peripheral venous blood samples of 14 women with and without endometriosis (n = 7 for each group).
