Higher expression of HSP70 and LOX-1 in the placental tissues of pre-eclampsia pregnancies.

Background: Pre-eclampsia, a hypertensive disorder of pregnancy is the main cause of fetal and maternal morbidity and mortality. Growing evidences suggest that placental oxidative stress involves in the pathogenesis of pre-eclampsia. The HSP70 is a novel marker of oxidative stress which binds with high avidity to LOX-1.

Positional relationship between natural killer cells and distribution of sympathetic nerves in decidualized mouse uterus.

Background: Uterine natural killer (uNK) cells are the most abundant leukocytes in pre-implantation endometrium and early pregnancy deciduas in humans and rodents. They are associated with structural changes in maternal spiral arteries but regulation of their recruitment and activation is incompletely understood. The major subpopulation of uNK cells in humans expresses CD56, the neural cell adhesion molecule (NCAM)-1 while their counterpart in mouse expresses asialoGM1, a brain ganglioside.
