This study measured soluble NKG2D ligands in peritoneal fluid using ELISA to assess their role in endometriosis pathology. The researchers compared levels across patients with deep infiltrating endometriosis, ovarian endometriomas, superficial disease, and healthy controls, excluding samples with undetectable values. Results indicated that MICA and MICB ratio levels differed significantly among the groups, correlating with the surgical classification of the disease severity. This paper is centrally about endometriosis — specifically investigating immune response markers in peritoneal fluid across different stages of the condition.

Abstract

Samples with undetectable levels of NKG2D ligands have been excluded. The peritoneal fluid MICA and MICB ratio levels among groups [DIE (n = 48), OMA (n = 31); SUP (n = 39) and controls (n = 78)] was significantly different by the Kruskal-Wallis test (P = 0.015 and P = 0.002 respectively). Post hoc test were performed using the with Dunn's Multiple Comparison Test. Peritoneal NKG2D ligands ratio values are represented on a logarithmic scale as a scatter dot plot. The medians with their interquartile ranges are reported.

Soluble Ligands for the NKG2D Receptor Are Released during Endometriosis and Correlate with Disease Severity Fig 2 Peritoneal NKG2D ligands levels measured by ELISA in patients with endometriosis and in controls according to the surgical classification of endometriosis.
