This study investigated the levels of soluble NKG2D ligands in peritoneal fluid collected from patients with endometriosis compared to control subjects following abdominopelvic exploration. Using enzyme-linked immunosorbent assay, the researchers measured concentrations of MICA and MICB molecules, finding that these soluble ligands are released during the disease process. The analysis revealed significant differences in the peritoneal fluid MICA and MICB ratios between the endometriosis group and controls, indicating a correlation with disease severity. This paper is centrally about endometriosis — specifically examining the role of immune-related soluble ligands in the peritoneal environment of affected patients.

Abstract

Samples with undetectable levels of NKG2D ligands have been excluded. The peritoneal fluid MICA and MICB ratio levels among groups was significantly different by the Mann Whitney test (P = 0.035 and P<0.001 respectively). Peritoneal NKG2D ligands ratio values are represented on a logarithmic scale as a scatter dot plot. The medians with their interquartile range are reported.
