FCGR1A and endometriosis: By differential expression analyses on manually gated mononuclear phagocytic subsets, we found that, in the proliferative phase, a greater frequency of CD91+ macrophages in endometrium of women with endometriosis express SIRPα compared to controls (Fig. 5A) and they have higher expression levels of CD64 in the proliferative phase of the menstrual cycle (Fig. 5B), corroborating the results observed with the unsupervised analysis.
