FosB-positive cells

downin rats1

1 study
  1. Maternal separation decreases FosB-positive cells in rats.

    “In the PVN, the number of FosB expressing cells decreased with age; this effect was greater in NMS females.”

17β-estradiol

downin rats1

1 study
  1. Maternal separation decreases 17β-estradiol in rats.

    “Age-related decline in 17β-oestradiol (E2) was greater in NMS rats than CTRL.”

ACE2

downin rats1−35%

1 study
  1. Maternal separation decreases ACE2 in rats (-35%).

    “In old females, ACE2 activity was 35% less in NMS than CTRL.”

1 study
  1. Maternal separation increases mean arterial pressure in rats.

    “Age-related rise in MAP was observed only in NMS”
