Do immune cells help break down the uterine lining during menstruation?
Lab tests suggest they do play a role, but the process is tightly regulated by other molecules to prevent excessive tissue damage.
What they did
Lab cultures of immune cells called neutrophils with uterine tissue cells. Researchers tested whether neutrophils could activate enzymes that break down tissue matrix.
What they found
When neutrophils from blood were cultured with uterine stromal fibroblasts, they activated enzymes that break down tissue. A protease called elastase appeared to play a role in this activation. However, neutrophils taken from the uterus itself did not activate these enzymes the same way, possibly because they produce different levels of elastase and inhibitors.
What it means for you
Immune cells may contribute to the normal breakdown of the uterine lining during menstruation, but the process is carefully regulated. This is lab work using cultured cells, so we cannot directly apply these findings to what happens in the living body.
