KLRD1 and endometriosis: Interestingly, 40 of the 92 genes encoding NK cell receptors and ligands in our list were also amongst the differentially regulated gene list in the baboon eutopic endometrium at 6 months after induction of endometriosis (reported in Additional file 3: Table S2 in Afshar et al. [29], and in Additional file 3: Table S2), suggesting a close homology between the baboon model of endometriosis induction with the human disease.
