Enhancement of the Expression of Progesterone Receptor on Progesterone‐Treated Lymphocytes After Immunotherapy in Unexplained Recurrent Spontaneous Abortion

PROBLEM: The immunological mechanism of an effective immunotherapy with paternal lymphocytes for unexplained recurrent spontaneous abortion (RSA) is not yet clear. Previous studies revealed that progesterone plays an important role in maintaining normal pregnancy and lower expression of progesterone receptor (PGR) on lymphocytes was found in RSA. Therefore, it was of interest to investigate whether immunotherapy for RSA would be able to enhance the expression of PGR on lymphocytes of RSA.
