Researchers find common immune system mechanism between pregnancy, cancer

Researchers found a molecular mechanism, shared in cancer and pregnancy, that suppresses the immune system. Block this mechanism, called B7-H4, and the immune system revs up to slow cancer's growth. Looking at mouse models and cell lines of breast and gynecologic cancers, the researchers identified the hormone progesterone as a key regulator of the B7-H4 immune checkpoint.
