Fas ligand+ fallopian tube epithelium induces apoptosis in both Fas receptor+ T lymphocytes and endometrial cells

In both FasR+ T lymphocytes and endometrial cells, FasL+ FT cells induce apoptosis. Data suggest that the FT epithelium acts as a barrier to limit the influx of lymphocytes as well as endometrial cells ascending the tube. Failure of these regulatory mechanisms may be related to the development of endometriosis.
