Dopamine transporters participate in the physiological regulation of prolactin.
1999 Free zinc increases at the site of injury after cortical stab wounds in mature but not immature rat brain. Prolactin activates all three populations of hypothalamic neuroend ocrine dopaminergic neurons in ovariectomized rats. Endothelin is an autocrine regulator of prolactin secretion. Ovarian steroids modulate responsiveness to dopamine and expression of G-proteins in lactotrophs.
