The endocervical mucosae of the female reproductive tract (FRT) not only serve as a physical barrier against microbial infection, but they also express a wide variety of immune mediators. The endocervical epithelial cells express a distinct profile of immune-regulators, which is higher than vaginal and ectocervical epithelial cells. Constant cytokine production would ensure rapid responses to infections and maintenance of the sterility of the upper genital tract. However, overproduction of cytokines could inhibit normal reproductive processes and stimulate excess growth and cell proliferation. The synthetic progestins medroxyprogesterone acetate (MPA) and norethisterone (NET) and its derivatives (norethisterone enanthate (NET-EN); norethisterone acetate (NET-A)) are synthetic steroidal hormones designed to elicit progestational effects similar to those of the endogenous hormone progesterone (P4). They are extensively used as contraceptives and in hormone replacement therapy (HRT). Numerous studies, however, have reported that synthetic progestins affect immune function, increase the risk of sexually transmitted infections (STIs) and also change the morphology of the cervicovaginal mucosa. Despite these findings little is known about the molecular mechanisms of action of MPA and NET, in particular their differential effects on gene expression. 2016-09-30T11:35:38Z 2016-09-30T11:35:38Z 2010 Doctoral Thesis Doctoral PhD http://hdl.handle.net/11427/22025 eng application/pdf Department of Molecular and Cell Biology Faculty of Science University of Cape Town |
