Evaluation of oestrogen and progesterone receptor expression in uterine mucosal lymphocytes

Abstract
Expression of the oestrogen and progesterone receptors on uterine mueosal leukocytes has been examined by dual immunohistology. Neither the oestrogen receptor nor the progesterone receptor was expressed by lymphocytes, macrophages or the distinctive population of uterine natural killer (NK) cells. Although the accumulation and survival of these NK cells appears to be hormonally dependent, the effects must therefore be indirect.
