Xie et al. [30] from a study carried out in human pMφ and peripheral blood mononuclear cells, concluded that the eutopic endometrium could reduce the phagocytic capacity of pMφ in women with endometriosis by increasing the expression of the Signal Regulatory Protein-α (SIRP-α), and decreasing the corresponding expression of the CD36 scavenger receptor (Table 2). The gene discussed is SIRPA; the disease is endometriosis.
