Further analysis showed that the expression of CD86,CD40, and MHC-II markers on the uDCs in controlgroup (abortion-prone mice) (39.2 ± 2.8%, 27.6 ±2.9%, and 62.5 ± 2.1% respectively) was noticeablyhigher than normal pregnant group (16.5 ± 2.5%,5.7 ± 1.7%, and 45.6 ± 3.2%, respectively, P<0.001,P<0.0001, P<0.001, Fig .3). Here, CD86 is linked to abortion.
