In the female reproductive tract, the innate immune system is modulated by two
sex steroid hormones, estrogen and progesterone. A cyclical wave of neutrophils
in the vaginal lumen is triggered by chemokines and correlates with circulating
estrogen levels. Classical estrogen signaling in the female reproductive tract is
activated through estrogen receptor ? (encoded by the Esr1 gene). To study the
role of estrogen action in the vagina, we used a mouse model in which Esr1 was
conditionally ablated from the epithelial cells (Wnt7a(cre/+); Esr1(f/f)).
Histological evidence showed that in response to a physical stress, the lack of
ESR1 caused the vaginal epithelium to deteriorate due to the absence of a
protective cornified layer and a reduction in keratin production. In the absence
of ESR1 in the vaginal epithelial tissue, we also observed an excess of
neutrophil infiltration, regardless of the estrous cycle stage. The histological
presence of neutrophils was found to correlate with persistent enzymatic activity
in the cervical-vaginal fluid. Together, these findings suggest that ESR1
activity in the vaginal epithelial cells is required to maintain proper
structural integrity of the vagina and immune response, both of which are
necessary for protecting the vagina against physical damage and resetting the
vaginal environment.
