This paper reviews published literature on how natural killer (NK) cell activity may contribute to the pathogenesis of endometriosis, emphasizing NK cytotoxic effector function and its ability to lyse target cells in an MHC class I-independent manner. It reports that endometriosis is associated with a defect in NK cell cytotoxicity, which can impair elimination of endometrial cells in ectopic sites, and that altered NK-mediated innate immunity may disturb adaptive immune functions and thereby support disease development and infertility. A key limitation is that the work is explicitly a literature review/summarization rather than a new primary study with original experiments. This paper is centrally about endometriosis — specifically, it reviews how impaired NK cell activity and NK-driven immune dysregulation may underlie endometriosis pathogenesis.

Abstract

Natural Killer (NK) cells are cytotoxic effector lymphocytes with the ability to lyse target cells in a major histocompatibility complex (MHC) class I-independent manner and without the need for prior antigen exposure. Data strongly suggested that NK cells play an important role in human reproduction and disturbance in their function can favor development of the gynecological disorders. In our study the role of NK cells in pathogenesis of endometriosis is reviewed and summarized from available literature. Endometriosis is related to a defect of NK cell cytotoxicity function in the ability to eliminate endometrial cells in ectopic sites. Alternations of the innate immunity mediated by NK cells may promote impairments or disrupt functions of adaptive immunity, which can contribute to development and progression of endometriosis and infertility associated with endometriosis. Aberrant immune responses by NK cells in affected women may represent risk factors for endometriosis and the repaired function can be a new treatment target of the affected women.
