The scientific evidence suggests that Neisseria gonorrhoeae (NG) infects human fallopian tubes by molecular mimicry in which pathogens act like a ligand to bind to epithelial cell surface human chorionic gonadotrophin (hCG)/luteinizing hormone (LH) receptors. The hCG-like molecule has been identified as ribosomal protein L12 in NG coat surface. Human fallopian tube epithelial cells have been shown to contain functional hCG/LH receptors. As previously shown in human fallopian tube organ and cell culture studies, cellular invasion and infection can be prevented by exposing the cells to excess hCG, which would outnumber and outcompete NG for receptor binding. Based on these data, we suggest testing hCG in clinical trials on infected women.
Keywords: Neisseria gonorrhoeae; fallopian tubes; hCG/LH receptors; human chorionic gonadotropin.
